<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>You can query/set/replace/unset options with this command. The name is
actually the section and the key separated by a dot, and the value will be
escaped.</p>
</div>
<div class="paragraph">
<p>Multiple lines can be added to an option by using the <code>--append</code> option.
If you want to update or unset an option which can occur on multiple
lines, <code>--value=</code><em>&lt;pattern&gt;</em> (which is an extended regular expression,
unless the <code>--fixed-value</code> option is given) needs to be given.  Only the
existing values that match the pattern are updated or unset.  If
you want to handle the lines that do <strong>not</strong> match the pattern, just
prepend a single exclamation mark in front (see also <a href="#EXAMPLES">EXAMPLES</a>),
but note that this only works when the <code>--fixed-value</code> option is not
in use.</p>
</div>
<div class="paragraph">
<p>The <code>--type=</code><em>&lt;type&gt;</em> option instructs <em>git config</em> to ensure that incoming and
outgoing values are canonicalize-able under the given &lt;type&gt;.  If no
<code>--type=</code><em>&lt;type&gt;</em> is given, no canonicalization will be performed. Callers may
unset an existing <code>--type</code> specifier with <code>--no-type</code>.</p>
</div>
<div class="paragraph">
<p>When reading, the values are read from the system, global and
repository local configuration files by default, and options
<code>--system</code>, <code>--global</code>, <code>--local</code>, <code>--worktree</code> and
<code>--file</code> <em>&lt;filename&gt;</em> can be used to tell the command to read from only
that location (see <a href="#FILES">FILES</a>).</p>
</div>
<div class="paragraph">
<p>When writing, the new value is written to the repository local
configuration file by default, and options <code>--system</code>, <code>--global</code>,
<code>--worktree</code>, <code>--file</code> <em>&lt;filename&gt;</em> can be used to tell the command to
write to that location (you can say <code>--local</code> but that is the
default).</p>
</div>
<div class="paragraph">
<p>This command will fail with non-zero status upon error.  Some exit
codes are:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>The section or key is invalid (ret=1),</p>
</li>
<li>
<p>no section or name was provided (ret=2),</p>
</li>
<li>
<p>the config file is invalid (ret=3),</p>
</li>
<li>
<p>the config file cannot be written (ret=4),</p>
</li>
<li>
<p>you try to unset an option which does not exist (ret=5),</p>
</li>
<li>
<p>you try to unset/set an option for which multiple lines match (ret=5), or</p>
</li>
<li>
<p>you try to use an invalid regexp (ret=6).</p>
</li>
</ul>
</div>
<div class="paragraph">
<p>On success, the command returns the exit code 0.</p>
</div>
<div class="paragraph">
<p>A list of all available configuration variables can be obtained using the
<code>git</code> <code>help</code> <code>--config</code> command.</p>

<h2 id="_commands">COMMANDS</h2>
<div class="sectionbody">
<div class="dlist">
<dl>
<dt class="hdlist1">list</dt>
<dd>
<p>List all variables set in config file, along with their values.</p>
</dd>
<dt class="hdlist1">get</dt>
<dd>
<p>Emits the value of the specified key. If key is present multiple times
in the configuration, emits the last value. If <code>--all</code> is specified,
emits all values associated with key. Returns error code 1 if key is
not present.</p>
</dd>
<dt class="hdlist1">set</dt>
<dd>
<p>Set value for one or more config options. By default, this command
refuses to write multi-valued config options. Passing <code>--all</code> will
replace all multi-valued config options with the new value, whereas
<code>--value=</code> will replace all config options whose values match the given
pattern.</p>
</dd>
<dt class="hdlist1">unset</dt>
<dd>
<p>Unset value for one or more config options. By default, this command
refuses to unset multi-valued keys. Passing <code>--all</code> will unset all
multi-valued config options, whereas <code>--value</code> will unset all config
options whose values match the given pattern.</p>
</dd>
<dt class="hdlist1">rename-section</dt>
<dd>
<p>Rename the given section to a new name.</p>
</dd>
<dt class="hdlist1">remove-section</dt>
<dd>
<p>Remove the given section from the configuration file.</p>
</dd>
<dt class="hdlist1">edit</dt>
<dd>
<p>Opens an editor to modify the specified config file; either
<code>--system</code>, <code>--global</code>, <code>--local</code> (default), <code>--worktree</code>, or
<code>--file</code> <em>&lt;config-file&gt;</em>.</p>
</dd>

<div class="sect1">
<h2 id="OPTIONS">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist">
<dl>
<dt class="hdlist1">--replace-all</dt>
<dd>
<p>Default behavior is to replace at most one line. This replaces
all lines matching the key (and optionally <code>--value=</code><em>&lt;pattern&gt;</em>).</p>
</dd>
<dt class="hdlist1">--append</dt>
<dd>
<p>Adds a new line to the option without altering any existing
values. This is the same as providing <em>--value=^$</em> in <code>set</code>.</p>
</dd>
<dt class="hdlist1">--comment &lt;message&gt;</dt>
<dd>
<p>Append a comment at the end of new or modified lines.</p>
<div class="paragraph">
<p>If <em>&lt;message&gt;</em> begins with one or more whitespaces followed
by #, it is used as-is.  If it begins with #, a space is
prepended before it is used.  Otherwise, a string " # " (a
space followed by a hash followed by a space) is prepended
to it.  The resulting string is placed immediately after
the value defined for the variable.  The <em>&lt;message&gt;</em> must
not contain linefeed characters (no multi-line comments are
permitted).</p>
</div>
</dd>
<dt class="hdlist1">--all</dt>
<dd>
<p>With <code>get</code>, return all values for a multi-valued key.</p>
</dd>
<dt class="hdlist1">--regexp</dt>
<dd>
<p>With <code>get</code>, interpret the name as a regular expression. Regular
expression matching is currently case-sensitive and done against a
canonicalized version of the key in which section and variable names
are lowercased, but subsection names are not.</p>
</dd>
<dt class="hdlist1">--url=&lt;URL&gt;</dt>
<dd>
<p>When given a two-part &lt;name&gt; as &lt;section&gt;.&lt;key&gt;, the value for
&lt;section&gt;.&lt;URL&gt;.&lt;key&gt; whose &lt;URL&gt; part matches the best to the
given URL is returned (if no such key exists, the value for
&lt;section&gt;.&lt;key&gt; is used as a fallback).  When given just the
&lt;section&gt; as name, do so for all the keys in the section and
list them.  Returns error code 1 if no value is found.</p>
</dd>
<dt class="hdlist1">--global</dt>
<dd>
<p>For writing options: write to global <code>~/.gitconfig</code> file
rather than the repository .<code>git/config</code>, write to
<code>$XDG_CONFIG_HOME/git/config</code> file if this file exists and the
<code>~/.gitconfig</code> file doesn&#8217;t.</p>
<div class="paragraph">
<p>For reading options: read only from global <code>~/.gitconfig</code> and from

<dt class="hdlist1">--worktree</dt>
<dd>
<p>Similar to <code>--local</code> except that <code>$GIT_DIR/config.worktree</code> is
read from or written to if <code>extensions.worktreeConfig</code> is
enabled. If not it&#8217;s the same as <code>--local</code>. Note that <code>$GIT_DIR</code>
is equal to <code>$GIT_COMMON_DIR</code> for the main working tree, but is of
the form <code>$GIT_DIR/worktrees/</code><em>&lt;id&gt;</em><code>/</code> for other working trees. See
<a href="git-worktree.html">git-worktree(1)</a> to learn how to enable
<code>extensions.worktreeConfig</code>.</p>

you can use <em>master:.gitmodules</em> to read values from the file
<em>.gitmodules</em> in the master branch. See "SPECIFYING REVISIONS"
section in <a href="gitrevisions.html">gitrevisions(7)</a> for a more complete list of
ways to spell blob names.</p>

<div class="paragraph">
<p>Use <code>--no-value</code> to unset <em>&lt;pattern&gt;</em>.</p>
</div>
</dd>
<dt class="hdlist1">--fixed-value</dt>
<dd>
<p>When used with <code>--value=</code><em>&lt;pattern&gt;</em>, treat <em>&lt;pattern&gt;</em> as
an exact string instead of a regular expression. This will restrict
the name/value pairs that are matched to only those where the value
is exactly equal to <em>&lt;pattern&gt;</em>.</p>

<h2 id="_configuration_file">CONFIGURATION FILE</h2>
<div class="sectionbody">
<div class="paragraph">
<p>The Git configuration file contains a number of variables that affect
the Git commands' behavior. The files .<code>git/config</code> and optionally
<code>config.worktree</code> (see the "CONFIGURATION FILE" section of
<a href="git-worktree.html">git-worktree(1)</a>) in each repository are used to store the
configuration for that repository, and <code>$HOME/.gitconfig</code> is used to
store a per-user configuration as fallback values for the .<code>git/config</code>
file. The file <code>/etc/gitconfig</code> can be used to store a system-wide
default configuration.</p>
</div>
<div class="paragraph">
<p>The configuration variables are used by both the Git plumbing
and the porcelain commands. The variables are divided into sections, wherein
the fully qualified variable name of the variable itself is the last
dot-separated segment and the section name is everything before the last
dot. The variable names are case-insensitive, allow only alphanumeric
characters and <code>-</code>, and must start with an alphabetic character.  Some
variables may appear multiple times; we say then that the variable is
multivalued.</p>
</div>
<div class="sect2">
<h3 id="_syntax">Syntax</h3>
<div class="paragraph">
<p>The syntax is fairly flexible and permissive.  Whitespace characters,
which in this context are the space character (SP) and the horizontal
tabulation (HT), are mostly ignored.  The <em>#</em> and <em>;</em> characters begin
comments to the end of line.  Blank lines are ignored.</p>
</div>
<div class="paragraph">
<p>The file consists of sections and variables.  A section begins with
the name of the section in square brackets and continues until the next
section begins.  Section names are case-insensitive.  Only alphanumeric
characters, <code>-</code> and . are allowed in section names.  Each variable
must belong to some section, which means that there must be a section
header before the first setting of a variable.</p>
</div>
<div class="paragraph">
<p>Sections can be further divided into subsections.  To begin a subsection
put its name in double quotes, separated by space from the section name,
in the section header, like in the example below:</p>
</div>
<div class="listingblock">
<div class="content">
<pre>        [section "subsection"]</pre>
</div>
</div>
<div class="paragraph">
<p>Subsection names are case sensitive and can contain any characters except
newline and the null byte. Doublequote " and backslash can be included
by escaping them as <code>\</code>" and <code>\\</code>, respectively. Backslashes preceding
other characters are dropped when reading; for example, <code>\t</code> is read as
<code>t</code> and <code>\0</code> is read as <code>0</code>. Section headers cannot span multiple lines.
Variables may belong directly to a section or to a given subsection. You
can have [<code>section</code>] if you have [<code>section</code> "subsection"], but you don&#8217;t
need to.</p>
</div>
<div class="paragraph">
<p>There is also a deprecated [<code>section.subsection</code>] syntax. With this
syntax, the subsection name is converted to lower-case and is also
compared case sensitively. These subsection names follow the same
restrictions as section names.</p>
</div>
<div class="paragraph">
<p>All the other lines (and the remainder of the line after the section
header) are recognized as setting variables, in the form
<em>name = value</em> (or just <em>name</em>, which is a short-hand to say that
the variable is the boolean "true").
The variable names are case-insensitive, allow only alphanumeric characters
and <code>-</code>, and must start with an alphabetic character.</p>
</div>
<div class="paragraph">
<p>Whitespace characters surrounding <code>name</code>, <code>=</code> and <code>value</code> are discarded.
Internal whitespace characters within <em>value</em> are retained verbatim.
Comments starting with either # or ; and extending to the end of line
are discarded.  A line that defines a value can be continued to the next
line by ending it with a backslash (<code>\</code>);  the backslash and the end-of-line
characters are discarded.</p>
</div>
<div class="paragraph">
<p>If <code>value</code> needs to contain leading or trailing whitespace characters,
it must be enclosed in double quotation marks (").  Inside double quotation
marks, double quote (") and backslash (<code>\</code>) characters must be escaped:
use <code>\</code>" for " and <code>\\</code> for <code>\</code>.</p>
</div>

<h3 id="_includes">Includes</h3>
<div class="paragraph">
<p>The <code>include</code> and <code>includeIf</code> sections allow you to include config
directives from another source. These sections behave identically to
each other with the exception that <code>includeIf</code> sections may be ignored
if their condition does not evaluate to true; see "Conditional includes"
below.</p>
</div>
<div class="paragraph">
<p>You can include a config file from another by setting the special
<code>include.path</code> (or <code>includeIf.*.path</code>) variable to the name of the file
to be included. The variable takes a pathname as its value, and is
subject to tilde expansion. These variables can be given multiple times.</p>
</div>
<div class="paragraph">
<p>The contents of the included file are inserted immediately, as if they
had been found at the location of the include directive. If the value of the
variable is a relative path, the path is considered to
be relative to the configuration file in which the include directive
was found.  See below for examples.</p>
</div>
</div>
<div class="sect2">
<h3 id="_conditional_includes">Conditional includes</h3>
<div class="paragraph">
<p>You can conditionally include a config file from another by setting an
<code>includeIf.</code><em>&lt;condition&gt;</em><code>.path</code> variable to the name of the file to be
included.</p>
</div>
<div class="paragraph">
<p>The condition starts with a keyword followed by a colon and some data
whose format and meaning depends on the keyword. Supported keywords
are:</p>
</div>
<div class="dlist">
<dl>
<dt class="hdlist1"><code>gitdir</code></dt>
<dd>
<p>The data that follows the keyword <code>gitdir</code> and a colon is used as a glob
pattern. If the location of the .git directory matches the
pattern, the include condition is met.</p>
<div class="paragraph">
<p>The .git location may be auto-discovered, or come from <code>$GIT_DIR</code>
environment variable. If the repository is auto-discovered via a .git
file (e.g. from submodules, or a linked worktree), the .git location
would be the final location where the .git directory is, not where the
.git file is.</p>
</div>
<div class="paragraph">
<p>The pattern can contain standard globbing wildcards and two additional
ones, <code>**/</code> and <code>/**</code>, that can match multiple path components. Please
refer to <a href="gitignore.html">gitignore(5)</a> for details. For convenience:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>If the pattern starts with <code>~/</code>, <code>~</code> will be substituted with the
content of the environment variable <code>HOME</code>.</p>
</li>
<li>
<p>If the pattern starts with .<code>/</code>, it is replaced with the directory
containing the current config file.</p>
</li>
<li>
<p>If the pattern does not start with either <code>~/</code>, .<code>/</code> or <code>/</code>, <code>**/</code>
will be automatically prepended. For example, the pattern <code>foo/bar</code>
becomes <code>**/foo/bar</code> and would match <code>/any/path/to/foo/bar</code>.</p>
</li>
<li>
<p>If the pattern ends with <code>/</code>, <code>**</code> will be automatically added. For
example, the pattern <code>foo/</code> becomes <code>foo/**</code>. In other words, it
matches "foo" and everything inside, recursively.</p>
</li>
</ul>
</div>
</dd>
<dt class="hdlist1"><code>gitdir/i</code></dt>
<dd>
<p>This is the same as <code>gitdir</code> except that matching is done
case-insensitively (e.g. on case-insensitive file systems)</p>
</dd>
<dt class="hdlist1"><code>onbranch</code></dt>
<dd>
<p>The data that follows the keyword <code>onbranch</code> and a colon is taken to be a
pattern with standard globbing wildcards and two additional
ones, <code>**/</code> and <code>/**</code>, that can match multiple path components.
If we are in a worktree where the name of the branch that is
currently checked out matches the pattern, the include condition
is met.</p>
<div class="paragraph">
<p>If the pattern ends with <code>/</code>, <code>**</code> will be automatically added. For
example, the pattern <code>foo/</code> becomes <code>foo/**</code>. In other words, it matches
all branches that begin with <code>foo/</code>. This is useful if your branches are
organized hierarchically and you would like to apply a configuration to
all the branches in that hierarchy.</p>
</div>
</dd>
<dt class="hdlist1"><code>hasconfig:remote.*.url</code></dt>
<dd>
<p>The data that follows this keyword and a colon is taken to
be a pattern with standard globbing wildcards and two
additional ones, <code>**/</code> and <code>/**</code>, that can match multiple
components. The first time this keyword is seen, the rest of
the config files will be scanned for remote URLs (without
applying any values). If there exists at least one remote URL
that matches this pattern, the include condition is met.</p>
<div class="paragraph">
<p>Files included by this option (directly or indirectly) are not allowed
to contain remote URLs.</p>
</div>
<div class="paragraph">
<p>Note that unlike other includeIf conditions, resolving this condition
relies on information that is not yet known at the point of reading the
condition. A typical use case is this option being present as a
system-level or global-level config, and the remote URL being in a
local-level config; hence the need to scan ahead when resolving this
condition. In order to avoid the chicken-and-egg problem in which
potentially-included files can affect whether such files are potentially
included, Git breaks the cycle by prohibiting these files from affecting
the resolution of these conditions (thus, prohibiting them from
declaring remote URLs).</p>
</div>
<div class="paragraph">
<p>As for the naming of this keyword, it is for forwards compatibility with
a naming scheme that supports more variable-based include conditions,
but currently Git only supports the exact keyword described above.</p>
</div>
</dd>
</dl>
</div>
<div class="paragraph">
<p>A few more notes on matching via <code>gitdir</code> and <code>gitdir/i</code>:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Symlinks in <code>$GIT_DIR</code> are not resolved before matching.</p>
</li>
<li>
<p>Both the symlink &amp; realpath versions of paths will be matched
outside of <code>$GIT_DIR</code>. E.g. if ~/git is a symlink to
/mnt/storage/git, both <code>gitdir:~/git</code> and <code>gitdir:/mnt/storage/git</code>
will match.</p>
<div class="paragraph">
<p>This was not the case in the initial release of this feature in
v2.13.0, which only matched the realpath version. Configuration that
wants to be compatible with the initial release of this feature needs
to either specify only the realpath version, or both versions.</p>
</div>
</li>
<li>
<p>Note that "../" is not special and will match literally, which is
unlikely what you want.</p>

<p>Values of many variables are treated as a simple string, but there
are variables that take values of specific types and there are rules
as to how to spell them.</p>
</div>
<div class="dlist">
<dl>
<dt class="hdlist1">boolean</dt>
<dd>
<p>When a variable is said to take a boolean value, many
synonyms are accepted for <em>true</em> and <em>false</em>; these are all
case-insensitive.</p>
<div class="openblock">
<div class="content">
<div class="dlist">
<dl>
<dt class="hdlist1">true</dt>
<dd>
<p>Boolean true literals are <code>yes</code>, <code>on</code>, <code>true</code>,
and <code>1</code>.  Also, a variable defined without <code>=</code> <em>&lt;value&gt;</em>
is taken as true.</p>
</dd>
<dt class="hdlist1">false</dt>
<dd>
<p>Boolean false literals are <code>no</code>, <code>off</code>, <code>false</code>,
<code>0</code> and the empty string.</p>
</dd>
</dl>
</div>
</div>
</div>
<div class="paragraph">
<p>When converting a value to its canonical form using the <code>--type=bool</code> type
specifier, <em>git config</em> will ensure that the output is "true" or
"false" (spelled in lowercase).</p>
</div>
</dd>
<dt class="hdlist1">integer</dt>
<dd>
<p>The value for many variables that specify various sizes can
be suffixed with <code>k</code>, <code>M</code>,&#8230;&#8203; to mean "scale the number by
1024", "by 1024x1024", etc.</p>
</dd>
<dt class="hdlist1">color</dt>
<dd>
<p>The value for a variable that takes a color is a list of
colors (at most two, one for foreground and one for background)
and attributes (as many as you want), separated by spaces.</p>
<div class="paragraph">
<p>The basic colors accepted are <code>normal</code>, <code>black</code>, <code>red</code>, <code>green</code>,
<code>yellow</code>, <code>blue</code>, <code>magenta</code>, <code>cyan</code>, <code>white</code> and <code>default</code>.  The first
color given is the foreground; the second is the background.  All the
basic colors except <code>normal</code> and <code>default</code> have a bright variant that can
be specified by prefixing the color with <code>bright</code>, like <code>brightred</code>.</p>
</div>
<div class="paragraph">
<p>The color <code>normal</code> makes no change to the color. It is the same as an
empty string, but can be used as the foreground color when specifying a
background color alone (for example, "normal red").</p>
</div>
<div class="paragraph">
<p>The color <code>default</code> explicitly resets the color to the terminal default,
for example to specify a cleared background. Although it varies between
terminals, this is usually not the same as setting to "white black".</p>
</div>
<div class="paragraph">
<p>Colors may also be given as numbers between 0 and 255; these use ANSI
256-color mode (but note that not all terminals may support this).  If
your terminal supports it, you may also specify 24-bit RGB values as
hex, like #ff0ab3, or 12-bit RGB values like #f1b, which is
equivalent to the 24-bit color #ff11bb.</p>
</div>
<div class="paragraph">
<p>The accepted attributes are <code>bold</code>, <code>dim</code>, <code>ul</code>, <code>blink</code>, <code>reverse</code>,
<code>italic</code>, and <code>strike</code> (for crossed-out or "strikethrough" letters).
The position of any attributes with respect to the colors
(before, after, or in between), doesn&#8217;t matter. Specific attributes may
be turned off by prefixing them with <code>no</code> or <code>no-</code> (e.g., <code>noreverse</code>,
<code>no-ul</code>, etc).</p>
</div>
<div class="paragraph">
<p>The pseudo-attribute <code>reset</code> resets all colors and attributes before
applying the specified coloring. For example, <code>reset</code> <code>green</code> will result
in a green foreground and default background without any active
attributes.</p>
</div>
<div class="paragraph">
<p>An empty color string produces no color effect at all. This can be used
to avoid coloring specific elements without disabling color entirely.</p>
</div>
<div class="paragraph">
<p>For git&#8217;s pre-defined color slots, the attributes are meant to be reset
at the beginning of each item in the colored output. So setting
<code>color.decorate.branch</code> to <code>black</code> will paint that branch name in a
plain <code>black</code>, even if the previous thing on the same output line (e.g.
opening parenthesis before the list of branch names in <code>log</code> <code>--decorate</code>
output) is set to be painted with <code>bold</code> or some other attribute.
However, custom log formats may do more complicated and layered
coloring, and the negated forms may be useful there.</p>
</div>
</dd>
<dt class="hdlist1">pathname</dt>
<dd>
<p>A variable that takes a pathname value can be given a
string that begins with "<code>~/</code>" or "<code>~user/</code>", and the usual
tilde expansion happens to such a string: <code>~/</code>
is expanded to the value of <code>$HOME</code>, and <code>~user/</code> to the
specified user&#8217;s home directory.</p>
<div class="paragraph">
<p>If a path starts with <code>%</code>(<code>prefix</code>)<code>/</code>, the remainder is interpreted as a
path relative to Git&#8217;s "runtime prefix", i.e. relative to the location
where Git itself was installed. For example, <code>%</code>(<code>prefix</code>)<code>/bin/</code> refers to
the directory in which the Git executable itself lives. If Git was
compiled without runtime prefix support, the compiled-in prefix will be
substituted instead. In the unlikely event that a literal path needs to
be specified that should <em>not</em> be expanded, it needs to be prefixed by
.<code>/</code>, like so: .<code>/%</code>(<code>prefix</code>)<code>/bin</code>.</p>
</div>
<div class="paragraph">
<p>If prefixed with <code>:</code>(<code>optional</code>), the configuration variable is treated
as if it does not exist, if the named path does not exist.</p>

<p>Command aliases for the <a href="git.html">git(1)</a> command wrapper. Aliases
can be defined using two syntaxes:</p>
<div class="openblock">
<div class="content">
<div class="olist arabic">
<ol class="arabic">
<li>
<p>Without a subsection, e.g., [<code>alias</code>] <code>co</code> <code>=</code> <code>checkout</code>. The alias
name ("co" in this example) is
limited to ASCII alphanumeric characters and <code>-</code>,
and is matched case-insensitively.</p>
</li>
<li>
<p>With a subsection, e.g., [<code>alias</code> "co"] <code>command</code> <code>=</code> <code>checkout</code>. The
alias name can contain any characters (except for newlines and NUL bytes),
including UTF-8, and is matched case-sensitively as raw bytes.
You define the action of the alias in the <code>command</code>.</p>
</li>
</ol>
</div>
</div>
</div>
<div class="paragraph">
<p>Examples:</p>
</div>
<div class="listingblock">
<div class="content">
<pre># Without subsection (ASCII alphanumeric and dash only)
[alias]
    co = checkout
    st = status

# With subsection (allows any characters, including UTF-8)
[alias "hämta"]
    command = fetch
[alias "rätta till"]
    command = commit --amend</pre>
</div>
</div>
<div class="paragraph">
<p>With a Git alias defined, e.g.,</p>
</div>
<div class="literalblock">
<div class="content">
<pre>$ git config --global alias.last "cat-file commit HEAD"
# Which is equivalent to
$ git config --global alias.last.command "cat-file commit HEAD"</pre>
</div>
</div>
<div class="paragraph">
<p><code>git</code> <code>last</code> is equivalent to <code>git</code> <code>cat-file</code> <code>commit</code> <code>HEAD</code>.</p>
</div>
<div class="paragraph">
<p>To avoid confusion and troubles with script usage, aliases that
hide existing Git commands are ignored except for deprecated
commands.  Arguments are split by
spaces, the usual shell quoting and escaping are supported.
A quote pair or a backslash can be used to quote them.</p>
</div>
<div class="paragraph">
<p>Note that the first word of an alias does not necessarily have to be a
command. It can be a command-line option that will be passed into the
invocation of <code>git</code>. In particular, this is useful when used with <code>-c</code>
to pass in one-time configurations or <code>-p</code> to force pagination. For example,
<code>loud-rebase</code> <code>=</code> <code>-c</code> <code>commit.verbose=true</code> <code>rebase</code> can be defined such that
running <code>git</code> <code>loud-rebase</code> would be equivalent to
<code>git</code> <code>-c</code> <code>commit.verbose=true</code> <code>rebase</code>. Also, <code>ps</code> <code>=</code> <code>-p</code> <code>status</code> would be a
helpful alias since <code>git</code> <code>ps</code> would paginate the output of <code>git</code> <code>status</code>
where the original command does not.</p>
</div>
<div class="paragraph">
<p>If the alias expansion is prefixed with an exclamation point,
it will be treated as a shell command.  For example, defining
<code>alias.new</code> <code>=</code> !gitk <code>--all</code> <code>--not</code> <code>ORIG_HEAD</code>, the invocation
<code>git</code> <code>new</code> is equivalent to running the shell command
<code>gitk</code> <code>--all</code> <code>--not</code> <code>ORIG_HEAD</code>.  Note:</p>
</div>
<div class="ulist">
<ul>
<li>
<p>Shell commands will be executed from the top-level directory of a
repository, which may not necessarily be the current directory.</p>
</li>
<li>
<p><code>GIT_PREFIX</code> is set as returned by running <code>git</code> <code>rev-parse</code> <code>--show-prefix</code>
from the original current directory. See <a href="git-rev-parse.html">git-rev-parse(1)</a>.</p>
</li>
<li>
<p>Shell command aliases always receive any extra arguments provided to
the Git command-line as positional arguments.</p>
<div class="ulist">
<ul>
<li>
<p>Care should be taken if your shell alias is a "one-liner" script
with multiple commands (e.g. in a pipeline), references multiple
arguments, or is otherwise not able to handle positional arguments
added at the end.  For example: <code>alias.cmd</code> <code>=</code> "!echo <code>$1</code> | <code>grep</code> <code>$2</code>"
called as <code>git</code> <code>cmd</code> <code>1</code> <code>2</code> will be executed as <em>echo $1 | grep $2
1 2</em>, which is not what you want.</p>
</li>
<li>
<p>A convenient way to deal with this is to write your script
operations in an inline function that is then called with any
arguments from the command-line.  For example <code>alias.cmd</code> <code>=</code> "!c() {
<code>echo</code> <code>$1</code> | <code>grep</code> <code>$2</code> ; }; <code>c</code>" will correctly execute the prior example.</p>
</li>
<li>
<p>Setting <code>GIT_TRACE=1</code> can help you debug the command being run for
your alias.</p>

<p>Commits are grouped into pseudo-merge groups based on whether or not

<p>Within a pseudo-merge group, commits may be further grouped into

between.</p>

where <code>f</code>(<code>n</code>) is the size of the `n`th group.</p>
<div class="paragraph">

decay rate cause consecutive groups to shrink at an increasing rate.

<div class="paragraph">
<p>If all groups are the same size, it is possible that groups containing

Parallel checkout usually delivers better performance for repositories
located on SSDs or over NFS. For repositories on spinning disks and/or machines
with a small number of cores, the default sequential checkout often performs
better. The size and compression level of a repository might also influence how
well the parallel version performs.

<p>Like hook-based file system monitors, the built-in file system monitor
can speed up Git commands that need to refresh the Git index

built-in monitor eliminates the need to install and maintain an
external third-party tool.</p>

<p>Note that if you concurrently use multiple versions of Git, such
as one version on the command line and another version in an IDE

allow boolean values in addition to hook pathnames.  Git versions
2.35.1 and prior will not understand the boolean values and will
consider the "true" or "false" values as hook pathnames to be
invoked.  Git versions 2.26 thru 2.35.1 default to hook protocol
V2 and will fall back to no fsmonitor (full scan).  Git versions
prior to 2.26 default to hook protocol V1 and will silently
assume there were no changes to report (no scan), so status
commands may report incomplete results.  For this reason, it is
best to upgrade all of your Git versions before using the built-in

the device number, if Git was compiled to use it), are
excluded from the check among these fields, leaving only the
whole-second part of mtime (and ctime, if <code>core.trustCtime</code>

<div class="paragraph">
<p>There are implementations of Git that do not leave usable values in

0x80 are not considered "unusual" any more. Double-quotes,
backslash and control characters are always escaped regardless
of the setting of this variable.  A simple space character is
not considered "unusual".  Many commands can output pathnames
completely verbatim using the <code>-z</code> option. The default value
is true.</p>

<dt class="hdlist1">core.eol</dt>

<p>Sets the line ending type to use in the working directory for
files that are marked as text (either by having the <code>text</code>
attribute set, or by having <code>text=auto</code> and Git auto-detecting
the contents as text).
Alternatives are <em>lf</em>, <em>crlf</em> and <em>native</em>, which uses the platform&#8217;s
native line ending.  The default value is <code>native</code>.  See
<a href="gitattributes.html">gitattributes(5)</a> for more information on end-of-line
conversion. Note that this value is ignored if <code>core.autocrlf</code>
is set to <code>true</code> or <code>input</code>.</p>
</dd>
<dt class="hdlist1">core.safecrlf</dt>
<dd>
<p>If true, makes Git check if converting <code>CRLF</code> is reversible when
end-of-line conversion is active.  Git will verify if a command
modifies a file in the work tree either directly or indirectly.
For example, committing a file followed by checking out the
same file should yield the original file in the work tree.  If
this is not the case for the current setting of
<code>core.autocrlf</code>, Git will reject the file.  The variable can
be set to "warn", in which case Git will only warn about an
irreversible conversion but continue the operation.</p>
<div class="paragraph">
<p>CRLF conversion bears a slight chance of corrupting data.
When it is enabled, Git will convert CRLF to LF during commit and LF to
CRLF during checkout.  A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by Git.  For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.</p>
</div>
<div class="paragraph">
<p>If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes.  Right
after committing you still have the original file in your work
tree and this file is not yet corrupted.  You can explicitly tell
Git that this file is binary and Git will handle the file
appropriately.</p>
</div>
<div class="paragraph">
<p>Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished.  In both cases CRLFs are removed
in an irreversible way.  For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.</p>
</div>
<div class="paragraph">
<p>Note, this safety check does not mean that a checkout will generate a
file identical to the original file for a different setting of
<code>core.eol</code> and <code>core.autocrlf</code>, but only for the current one.  For
example, a text file with <code>LF</code> would be accepted with <code>core.eol=lf</code>
and could later be checked out with <code>core.eol=crlf</code>, in which case the
resulting file would contain <code>CRLF</code>, although the original file
contained <code>LF</code>.  However, in both work trees the line endings would be
consistent, that is either all <code>LF</code> or all <code>CRLF</code>, but never mixed.  A
file with mixed line endings would be reported by the <code>core.safecrlf</code>
mechanism.</p>
</div>

files, count 64-byte chunks instead, since binary files have no
natural concept of lines). This is a more expensive <code>--dirstat</code>

<p>Compute the dirstat numbers by counting the number of files changed.
Each changed file counts equally in the dirstat analysis. This is

<dd>
<p>Provides the default value for the <code>--from</code> option to format-patch.
Accepts a boolean value, or a name and email address.  If false,
format-patch defaults to <code>--no-from</code>, using commit authors directly in
the "From:" field of patch mails.  If true, format-patch defaults to
<code>--from</code>, using your committer identity in the "From:" field of patch

<dt class="hdlist1">format.thread</dt>
<dd>
<p>The default threading style for <em>git format-patch</em>.  Can be
a boolean value, or <code>shallow</code> or <code>deep</code>.  <code>shallow</code> threading
makes every mail a reply to the head of the series,
where the head is chosen from the cover letter, the
<code>--in-reply-to</code>, and the first patch mail, in this order.
<code>deep</code> threading makes every mail a reply to the previous one.
A true boolean value is the same as <code>shallow</code>, and a false
value disables threading.</p>
</dd>
<dt class="hdlist1">format.signOff</dt>
<dd>
<p>A boolean value which lets you enable the <code>-s/--signoff</code> option of
format-patch by default. <strong>Note:</strong> Adding the <code>Signed-off-by</code> trailer to a

</dd>
<dt class="hdlist1">format.coverLetter</dt>
<dd>
<p>A boolean that controls whether to generate a cover-letter when

Default is false.</p>
</dd>
<dt class="hdlist1">format.commitListFormat</dt>
<dd>
<p>When the <code>--commit-list-format</code> option is not given, <code>format-patch</code>

</dd>
<dt class="hdlist1">format.useAutoBase</dt>
<dd>
<p>A boolean value which lets you enable the <code>--base=auto</code> option of
format-patch by default. Can also be set to "whenAble" to allow
enabling <code>--base=auto</code> if a suitable base is available, but to skip
adding base info otherwise without the format dying.</p>
</dd>
<dt class="hdlist1">format.notes</dt>
<dd>
<p>Provides the default value for the <code>--notes</code> option to
format-patch. Accepts a boolean value, or a ref which specifies
where to get notes. If false, format-patch defaults to
<code>--no-notes</code>. If true, format-patch defaults to <code>--notes</code>. If
set to a non-boolean value, format-patch defaults to
<code>--notes=</code><em>&lt;ref&gt;</em>, where <code>ref</code> is the non-boolean value. Defaults
to false.</p>

implementation, which could save itself some work with an already sorted
list. Unless you had a humongous list there was no reason to go out of
your way to pre-sort the list. After Git version 2.20 a hash implementation

</dd>
<dt class="hdlist1">gc.packRefs</dt>
<dd>
<p>Running <code>git</code> <code>pack-refs</code> in a repository renders it
unclonable by Git versions prior to 1.5.1.2 over dumb
transports such as HTTP.  This variable determines whether
<em>git gc</em> runs <code>git</code> <code>pack-refs</code>. This can be set to <code>notbare</code>
to enable it within all non-bare repos or it can be set to a
boolean value.  The default is <code>true</code>.</p>
</dd>
<dt class="hdlist1">gc.cruftPacks</dt>
<dd>
<p>Store unreachable objects in a cruft pack (see

is <code>true</code>.</p>
</dd>
<dt class="hdlist1">gc.maxCruftSize</dt>
<dd>
<p>Limit the size of new cruft packs when repacking. When
specified in addition to <code>--max-cruft-size</code>, the command line
option takes priority. See the <code>--max-cruft-size</code> option of
<a href="git-repack.html">git-repack(1)</a>.</p>
</dd>
<dt class="hdlist1">gc.pruneExpire</dt>
<dd>
<p>When <em>git gc</em> is run, it will call <em>prune --expire 2.weeks.ago</em>
(and <em>repack --cruft --cruft-expiration 2.weeks.ago</em> if using
cruft packs via <code>gc.cruftPacks</code> or <code>--cruft</code>).  Override the
grace period with this config variable.  The value "now" may be
used to disable this grace period and always prune unreachable
objects immediately, or "never" may be used to suppress pruning.
This feature helps prevent corruption when <em>git gc</em> runs
concurrently with another process writing to the repository; see
the "NOTES" section of <a href="git-gc.html">git-gc(1)</a>.</p>
</dd>
<dt class="hdlist1">gc.worktreePruneExpire</dt>

<div class="paragraph">
<p>These types of entries are generally created as a result of using <code>git</code>
<code>commit</code> <code>--amend</code> or <code>git</code> <code>rebase</code> and are the commits prior to the amend

<dt class="hdlist1">gitcvs.usecrlfattr</dt>
<dd>
<p>If true, the server will look up the end-of-line conversion
attributes for files to determine the <code>-k</code> modes to use. If
the attributes force Git to treat a file as text,
the <code>-k</code> mode will be left blank so CVS clients will
treat it as text. If they suppress text conversion, the file
will be set with <em>-kb</em> mode, which suppresses any newline munging
the client might otherwise do. If the attributes do not allow
the file type to be determined, then <code>gitcvs.allBinary</code> is
used. See <a href="gitattributes.html">gitattributes(5)</a>.</p>
</dd>
<dt class="hdlist1">gitcvs.allBinary</dt>
<dd>
<p>This is used if <code>gitcvs.usecrlfattr</code> does not resolve
the correct <em>-kb</em> mode to use. If true, all
unresolved files are sent to the client in
mode <em>-kb</em>. This causes the client to treat them
as binary files, which suppresses any newline munging it
otherwise might do. Alternatively, if it is set to "guess",
then the contents of the file are examined to decide if
it is binary, similar to <code>core.autocrlf</code>.</p>

<dd>
<p>Pathname of the program to use instead of "<code>gpg</code>" when
making or verifying a PGP signature. The program must support the
same command-line interface as GPG, namely, to verify a detached
signature, "<code>gpg</code> <code>--verify</code> <code>$signature</code> <code>-</code> &lt;$file" is run, and the
program is expected to signal a good signature by exiting with
code 0.  To generate an ASCII-armored detached signature, the
standard input of "<code>gpg</code> <code>-bsau</code> <code>$key</code>" is fed with the contents to be
signed, and the program is expected to send the result to its
standard output.</p>
</dd>
<dt class="hdlist1">gpg.format</dt>
<dd>
<p>Specifies which key format to use when signing with <code>--gpg-sign</code>.
Default is "openpgp". Other possible values are "x509", "ssh".</p>

<p>Specifies a minimum trust level for signature verification.  If
this option is unset, then signature verification for merge
operations requires a key with at least <code>marginal</code> trust.  Other
operations that perform signature verification require a key
with at least <code>undefined</code> trust.  Setting this option overrides

<dt class="hdlist1">gpg.ssh.defaultKeyCommand</dt>
<dd>
<p>This command will be run when user.signingkey is not set and a ssh
signature is requested. On successful exit a valid ssh public key
prefixed with <code>key::</code> is expected in the first line of its output.
This allows for a script doing a dynamic lookup of the correct public
key when it is impractical to statically configure <code>user.signingKey</code>.
For example when keys or SSH Certificates are rotated frequently or
selection of the right key depends on external factors unknown to git.</p>
</dd>
<dt class="hdlist1">gpg.ssh.allowedSignersFile</dt>
<dd>
<p>A file containing ssh public keys which you are willing to trust.
The file consists of one or more lines of principals followed by an ssh
public key.
e.g.: <code>user1@example.com,user2@example.com</code> <code>ssh-rsa</code> <code>AAAAX1..</code>.
See ssh-keygen(1) "ALLOWED SIGNERS" for details.
The principal is only used to identify the key and is available when
verifying a signature.</p>
<div class="paragraph">
<p>SSH has no concept of trust levels like gpg does. To be able to differentiate
between valid signatures and trusted signatures the trust level of a signature
verification is set to <code>fully</code> when the public key is present in the allowedSignersFile.
Otherwise the trust level is <code>undefined</code> and git verify-commit/tag will fail.</p>
</div>
<div class="paragraph">
<p>This file can be set to a location outside of the repository and every developer
maintains their own trust store. A central repository server could generate this
file automatically from ssh keys with push access to verify the code against.
In a corporate setting this file is probably generated at a global location
from automation that already handles developer ssh keys.</p>
</div>
<div class="paragraph">
<p>A repository that only allows signed commits can store the file
in the repository itself using a path relative to the top-level of the working tree.
This way only committers with an already valid key can add or change keys in the keyring.</p>

<div class="paragraph">
<p>Since OpensSSH 8.8 this file allows specifying a key lifetime using valid-after &amp;
valid-before options. Git will mark signatures as valid if the signing key was

<p>The command to execute for <code>hook.</code><em>&lt;friendly-name&gt;</em>. <em>&lt;friendly-name&gt;</em>
is a unique name that identifies this hook. The hook events that
trigger the command are configured with <code>hook.</code><em>&lt;friendly-name&gt;</em><code>.event</code>.
The value can be an executable path or a shell oneliner. If more than
one value is specified for the same <em>&lt;friendly-name&gt;</em>, only the last
value parsed is used. See <a href="git-hook.html">git-hook(1)</a>.</p>
</dd>
<dt class="hdlist1">hook.&lt;friendly-name&gt;.event</dt>
<dd>
<p>The hook events that trigger <code>hook.</code><em>&lt;friendly-name&gt;</em>. The value is the
name of a hook event, like "pre-commit" or "update". (See
<a href="githooks.html">githooks(5)</a> for a complete list of hook events.) On the
specified event, the associated <code>hook.</code><em>&lt;friendly-name&gt;</em><code>.command</code> is executed.
This is a multi-valued key. To run <code>hook.</code><em>&lt;friendly-name&gt;</em> on multiple
events, specify the key more than once. An empty value resets
the list of events, clearing any previously defined events for
<code>hook.</code><em>&lt;friendly-name&gt;</em>. See <a href="git-hook.html">git-hook(1)</a>.</p>
<div class="paragraph">
<p>The <em>&lt;friendly-name&gt;</em> must not be the same as a known hook event name
(e.g. do not use <code>hook.pre-commit.event</code>). Using a known event name as
a friendly-name is a fatal error because it creates an ambiguity with
<code>hook.</code><em>&lt;event&gt;</em><code>.enabled</code> and <code>hook.</code><em>&lt;event&gt;</em><code>.jobs</code>. For unknown event names,
a warning is issued when <em>&lt;friendly-name&gt;</em> matches the event value.</p>
</div>
</dd>
<dt class="hdlist1">hook.&lt;friendly-name&gt;.enabled</dt>
<dd>
<p>Whether the hook <code>hook.</code><em>&lt;friendly-name&gt;</em> is enabled. Defaults to <code>true</code>.
Set to <code>false</code> to disable the hook without removing its
configuration. This is particularly useful when a hook is defined
in a system or global config file and needs to be disabled for a
specific repository. See <a href="git-hook.html">git-hook(1)</a>.</p>
</dd>
<dt class="hdlist1">hook.&lt;friendly-name&gt;.parallel</dt>
<dd>
<p>Whether the hook <code>hook.</code><em>&lt;friendly-name&gt;</em> may run in parallel with other hooks
for the same event. Defaults to <code>false</code>. Set to <code>true</code> only when the
hook script is safe to run concurrently with other hooks for the same
event. If any hook for an event does not have this set to <code>true</code>,
all hooks for that event run sequentially regardless of <code>hook.jobs</code>.
Only configured (named) hooks need to declare this. Traditional hooks
found in the hooks directory do not need to, and run in parallel when
the effective job count is greater than 1. See <a href="git-hook.html">git-hook(1)</a>.</p>
</dd>
<dt class="hdlist1">hook.&lt;event&gt;.enabled</dt>
<dd>
<p>Switch to enable or disable all hooks for the <em>&lt;event&gt;</em> hook event.
When set to <code>false</code>, no hooks fire for that event, regardless of any
per-hook <code>hook.</code><em>&lt;friendly-name&gt;</em><code>.enabled</code> settings. Defaults to <code>true</code>.
See <a href="git-hook.html">git-hook(1)</a>.</p>
<div class="paragraph">
<p>Note on naming: <em>&lt;event&gt;</em> must be the event name (e.g. <code>pre-commit</code>),
not a hook friendly-name. Since using a known event name as a
friendly-name is disallowed (see <code>hook.</code><em>&lt;friendly-name&gt;</em><code>.event</code> above),
there is no ambiguity between event-level and per-hook .<code>enabled</code>
settings for known events. For unknown events, if a friendly-name
matches the event name despite the warning, .<code>enabled</code> is treated
as per-hook only.</p>
</div>
</dd>
<dt class="hdlist1">hook.&lt;event&gt;.jobs</dt>
<dd>
<p>Specifies how many hooks can be run simultaneously for the <em>&lt;event&gt;</em>
hook event (e.g. <code>hook.post-receive.jobs</code> <code>=</code> <code>4</code>). Overrides <code>hook.jobs</code>
for this specific event. The same parallelism restrictions apply: this
setting has no effect unless all configured hooks for the event have
<code>hook.</code><em>&lt;friendly-name&gt;</em><code>.parallel</code> set to <code>true</code>. Set to <code>-1</code> to use the
number of available CPU cores. Must be a positive integer or <code>-1</code>;
zero is rejected with a warning. See <a href="git-hook.html">git-hook(1)</a>.</p>
<div class="paragraph">
<p>Note on naming: although this key resembles <code>hook.</code><em>&lt;friendly-name&gt;</em><code>.*</code>
(a per-hook setting), <em>&lt;event&gt;</em> must be the event name, not a hook
friendly name. The key component is stored literally and looked up by
event name at runtime with no translation between the two namespaces.
A key like <code>hook.my-hook.jobs</code> is stored under "my-hook" but the
lookup at runtime uses the event name (e.g. "post-receive"), so
<code>hook.my-hook.jobs</code> is silently ignored even when <code>my-hook</code> is
registered for that event. Use <code>hook.post-receive.jobs</code> or any other
valid event name when setting <code>hook.</code><em>&lt;event&gt;</em><code>.jobs</code>.</p>
</div>
</dd>
<dt class="hdlist1">hook.jobs</dt>
<dd>
<p>Specifies how many hooks can be run simultaneously during parallelized
hook execution. If unspecified, defaults to 1 (serial execution).
Set to <code>-1</code> to use the number of available CPU cores.
Can be overridden on a per-event basis with <code>hook.</code><em>&lt;event&gt;</em><code>.jobs</code>.
Some hooks always run sequentially regardless of this setting because
they operate on shared data and cannot safely be parallelized:</p>

addition to the syntax understood by curl, it is possible to specify a
proxy string with a user name but no password, in which case git will
attempt to acquire one in the same way it does for other credentials. See
<a href="gitcredentials.html">gitcredentials(7)</a> for more information. The syntax thus is

<p>Maximum size in bytes of the buffer used by smart HTTP
transports when POSTing data to the remote system.
For requests larger than this buffer size, HTTP/1.1 and
Transfer-Encoding: chunked is used to avoid creating a
massive pack file locally.  Default is 1 MiB, which is
sufficient for most requests.</p>
<div class="paragraph">
<p>Note that raising this limit is only effective for disabling chunked
transfer encoding and therefore should be used only where the remote

Defaults to 0 (retry immediately). When a Retry-After header is
present, its value takes precedence over this setting; however,
automatic use of the server-provided <code>Retry-After</code> header requires
libcurl 7.66.0 or later. On older versions, configure this setting

is configured with a value that exceeds this maximum, Git will fail
immediately rather than waiting. Default is 300 seconds (5 minutes).
Can be overridden by the <code>GIT_HTTP_MAX_RETRY_TIME</code> environment
variable. See also <code>http.retryAfter</code> and <code>http.maxRetries</code>.</p>
</dd>
<dt class="hdlist1">http.noEPSV</dt>
<dd>
<p>A boolean which disables using of EPSV ftp command by curl.
This can be helpful with some "poor" ftp servers which don&#8217;t
support EPSV mode. Can be overridden by the <code>GIT_CURL_FTP_NO_EPSV</code>
environment variable. Default is false (curl will use EPSV).</p>
</dd>
<dt class="hdlist1">http.userAgent</dt>
<dd>
<p>The HTTP USER_AGENT string presented to an HTTP server.  The default
value represents the version of the Git client such as git/1.7.1.
This option allows you to override this value to a more common value
such as Mozilla/4.0.  This may be necessary, for instance, if
connecting through a firewall that restricts HTTP connections to a set
of common USER_AGENT strings (but not including those like git/1.7.1).
Can be overridden by the <code>GIT_HTTP_USER_AGENT</code> environment variable.</p>
</dd>
<dt class="hdlist1">http.followRedirects</dt>
<dd>
<p>Whether git should follow HTTP redirects. If set to <code>true</code>, git
will transparently follow any redirect issued by a server it
encounters. If set to <code>false</code>, git will treat all redirects as
errors. If set to <code>initial</code>, git will follow redirects only for
the initial request to a remote, but not for subsequent
follow-up HTTP requests. Since git uses the redirected URL as
the base for the follow-up requests, this is generally
sufficient. The default is <code>initial</code>.</p>
</dd>
<dt class="hdlist1">http.&lt;url&gt;.*</dt>
<dd>
<p>Any of the http.* options above can be applied selectively to some URLs.
For a config key to match a URL, each element of the config key is
compared to that of the URL, in the following order:</p>
<div class="openblock">
<div class="content">
<div class="olist arabic">
<ol class="arabic">
<li>
<p>Scheme (e.g., <code>https</code> in <code>https://example.com/</code>). This field
must match exactly between the config key and the URL.</p>
</li>
<li>
<p>Host/domain name (e.g., <code>example.com</code> in <code>https://example.com/</code>).
This field must match between the config key and the URL. It is
possible to specify a <code>*</code> as part of the host name to match all subdomains
at this level. <code>https://*.example.com/</code> for example would match
<code>https://foo.example.com/</code>, but not <code>https://foo.bar.example.com/</code>.</p>
</li>
<li>
<p>Port number (e.g., <code>8080</code> in <code>http://example.com:8080/</code>).
This field must match exactly between the config key and the URL.
Omitted port numbers are automatically converted to the correct
default for the scheme before matching.</p>
</li>
<li>
<p>Path (e.g., <code>repo.git</code> in <code>https://example.com/repo.git</code>). The
path field of the config key must match the path field of the URL
either exactly or as a prefix of slash-delimited path elements.  This means
a config key with path <code>foo/</code> matches URL path <code>foo/bar</code>.  A prefix can only
match on a slash (<code>/</code>) boundary.  Longer matches take precedence (so a config
key with path <code>foo/bar</code> is a better match to URL path <code>foo/bar</code> than a config
key with just path <code>foo/</code>).</p>
</li>
<li>
<p>User name (e.g., <code>user</code> in <code>https://user@example.com/repo.git</code>). If
the config key has a user name it must match the user name in the
URL exactly. If the config key does not have a user name, that
config key will match a URL with any user name (including none),
but at a lower precedence than a config key with a user name.</p>
</li>
</ol>
</div>
</div>
</div>
<div class="paragraph">
<p>The list above is ordered by decreasing precedence; a URL that matches
a config key&#8217;s path is preferred to one that matches its user name. For example,
if the URL is <code>https://user@example.com/foo/bar</code> a config key match of
<code>https://example.com/foo</code> will be preferred over a config key match of
<code>https://user@example.com</code>.</p>
</div>
<div class="paragraph">
<p>All URLs are normalized before attempting any matching (the password part,
if embedded in the URL, is always ignored for matching purposes) so that
equivalent URLs that are simply spelled differently will match properly.
Environment variable settings always override any matches.  The URLs that are
matched against are those given directly to Git commands.  This means any URLs
visited as a result of a redirection do not participate in matching.</p>
</div>
</dd>
<dt class="hdlist1">i18n.commitEncoding</dt>
<dd>
<p>Character encoding the commit messages are stored in; Git itself
does not care per se, but this information is necessary e.g. when
importing commits from emails or in the gitk graphical history
browser (and possibly in other places in the future or in other
porcelains). See e.g. <a href="git-mailinfo.html">git-mailinfo(1)</a>. Defaults to <em>utf-8</em>.</p>

<dt class="hdlist1"><code>imap.folder</code></dt>
<dd>
<p>The folder to drop the mails into, which is typically the Drafts
folder. For example: <code>INBOX.Drafts</code>, <code>INBOX/Drafts</code> or
[<code>Gmail</code>]<code>/Drafts</code>. The IMAP folder to interact with MUST be specified;
the value of this configuration variable is used as the fallback
default value when the <code>--folder</code> option is not given.</p>

<dt class="hdlist1"><code>imap.tunnel</code></dt>
<dd>
<p>Command used to set up a tunnel to the IMAP server through which
commands will be piped instead of using a direct network connection
to the server. Required when <code>imap.host</code> is not set.</p>
</dd>
<dt class="hdlist1"><code>imap.host</code></dt>
<dd>
<p>A URL identifying the server. Use an <code>imap://</code> prefix for non-secure
connections and an <code>imaps://</code> prefix for secure connections.
Ignored when <code>imap.tunnel</code> is set, but required otherwise.</p>
</dd>
<dt class="hdlist1"><code>imap.user</code></dt>
<dd>
<p>The username to use when logging in to the server.</p>

<p>The password to use when logging in to the server.</p>
</dd>
<dt class="hdlist1"><code>imap.port</code></dt>
<dd>
<p>An integer port number to connect to on the server.
Defaults to 143 for <code>imap://</code> hosts and 993 for <code>imaps://</code> hosts.
Ignored when <code>imap.tunnel</code> is set.</p>
</dd>
<dt class="hdlist1"><code>imap.sslverify</code></dt>
<dd>
<p>A boolean to enable/disable verification of the server certificate
used by the SSL/TLS connection. Default is <code>true</code>. Ignored when
<code>imap.tunnel</code> is set.</p>
</dd>
<dt class="hdlist1"><code>imap.preformattedHTML</code></dt>
<dd>
<p>A boolean to enable/disable the use of html encoding when sending
a patch.  An html encoded patch will be bracketed with <em>&lt;pre&gt;</em>
and have a content type of text/html.  Ironically, enabling this
option causes Thunderbird to send the patch as a plain/text,
format=fixed email.  Default is <code>false</code>.</p>
</dd>
<dt class="hdlist1"><code>imap.authMethod</code></dt>
<dd>
<p>Specify the authentication method for authenticating with the IMAP server.
If Git was built with the NO_CURL option, or if your curl version is older
than 7.34.0, or if you&#8217;re running git-imap-send with the <code>--no-curl</code>
option, the only supported methods are <code>PLAIN</code>, <code>CRAM-MD5</code>, <code>OAUTHBEARER</code>
and <code>XOAUTH2</code>. If this is not set then <code>git</code> <code>imap-send</code> uses the basic IMAP
plaintext <code>LOGIN</code> command.</p>
</dd>
<dt class="hdlist1">include.path</dt>
<dt class="hdlist1">includeIf.&lt;condition&gt;.path</dt>
<dd>
<p>Special variables to include other configuration files. See

specifically the "Includes" and "Conditional Includes" subsections.</p>
</dd>
<dt class="hdlist1">index.recordEndOfIndexEntries</dt>
<dd>
<p>Specifies whether the index file should include an "End Of Index
Entry" section. This reduces index load time on multiprocessor
machines but produces a message "ignoring EOIE extension" when
reading the index using Git versions before 2.20. Defaults to
<em>true</em> if index.threads has been explicitly enabled, <em>false</em>
otherwise.</p>
</dd>
<dt class="hdlist1">index.recordOffsetTable</dt>
<dd>
<p>Specifies whether the index file should include an "Index Entry
Offset Table" section. This reduces index load time on
multiprocessor machines but produces a message "ignoring IEOT
extension" when reading the index using Git versions before 2.20.
Defaults to <em>true</em> if index.threads has been explicitly enabled,
<em>false</em> otherwise.</p>
</dd>
<dt class="hdlist1">index.sparse</dt>
<dd>
<p>When enabled, write the index using sparse-directory entries. This
has no effect unless <code>core.sparseCheckout</code> and
<code>core.sparseCheckoutCone</code> are both enabled. Defaults to <em>false</em>.</p>
</dd>
<dt class="hdlist1">index.threads</dt>
<dd>
<p>Specifies the number of threads to spawn when loading the index.
This is meant to reduce index load time on multiprocessor machines.
Specifying 0 or <em>true</em> will cause Git to auto-detect the number of
CPUs and set the number of threads accordingly. Specifying 1 or
<em>false</em> will disable multithreading. Defaults to <em>true</em>.</p>
</dd>
<dt class="hdlist1">index.version</dt>
<dd>
<p>Specify the version with which new index files should be
initialized.  This does not affect existing repositories.
If <code>feature.manyFiles</code> is enabled, then the default is 4.</p>
</dd>
<dt class="hdlist1">index.skipHash</dt>
<dd>
<p>When enabled, do not compute the trailing hash for the index file.
This accelerates Git commands that manipulate the index, such as
<code>git</code> <code>add</code>, <code>git</code> <code>commit</code>, or <code>git</code> <code>status</code>. Instead of storing the
checksum, write a trailing set of bytes with value zero, indicating
that the computation was skipped.</p>
<div class="paragraph">
<p>If you enable <code>index.skipHash</code>, then Git clients older than 2.13.0 will

</li>
<li>
<p><code>geometric</code>: This strategy performs geometric repacking of packfiles and
keeps auxiliary data structures up-to-date. The strategy expires data in the
reflog and removes worktrees that cannot be located anymore. When the
geometric repacking strategy would decide to do an all-into-one repack, then
the strategy generates a cruft pack for all unreachable objects. Objects that
are already part of a cruft pack will be expired.</p>
<div class="paragraph">
<p>This repacking strategy is a full replacement for the <code>gc</code> strategy and is

activities that do not delete any data. This does not schedule the <code>gc</code>
task, but runs the <code>prefetch</code> and <code>commit-graph</code> tasks hourly, the

a <code>=======</code> marker, changes made by the other side, and then
a &gt;&gt;&gt;&gt;&gt;&gt;&gt; marker.  An alternate style, "diff3", adds a |||||||
marker and the original text before the <code>=======</code> marker.  The
"merge" style tends to produce smaller conflict regions than diff3,
both because of the exclusion of the original text, and because
when a subset of lines match on the two sides, they are just pulled
out of the conflict region.  Another alternate style, "zdiff3", is
similar to diff3 but removes matching lines on the two sides from
the conflict region when those matching lines appear near either
the beginning or end of a conflict region.</p>

</dd>
<dt class="hdlist1">pack.islandCore</dt>
<dd>
<p>Specify an island name which gets to have its objects be
packed first. This creates a kind of pseudo-pack at the front
of one pack, so that the objects from the specified island are
hopefully faster to copy into any pack that should be served
to a user requesting these objects. In practice this means
that the island specified should likely correspond to what is

</dd>
<dt class="hdlist1">pack.deltaCacheSize</dt>
<dd>
<p>The maximum memory in bytes used for caching deltas in
<a href="git-pack-objects.html">git-pack-objects(1)</a> before writing them out to a pack.
This cache is used to speed up the writing object phase by not
having to recompute the final delta result once the best match
for all objects is found.  Repacking large repositories on machines
which are tight with memory might be badly impacted by this though,
especially if this cache pushes the system into swapping.
A value of 0 means no limit. The smallest size of 1 byte may be
used to virtually disable this cache. Defaults to 256 MiB.</p>
</dd>
<dt class="hdlist1">pack.deltaCacheLimit</dt>
<dd>
<p>The maximum size of a delta, that is cached in
<a href="git-pack-objects.html">git-pack-objects(1)</a>. This cache is used to speed up the
writing object phase by not having to recompute the final delta
result once the best match for all objects is found.
Defaults to 1000. Maximum value is 65535.</p>
</dd>
<dt class="hdlist1">pack.threads</dt>
<dd>
<p>Specifies the number of threads to spawn when searching for best
delta matches.  This requires that <a href="git-pack-objects.html">git-pack-objects(1)</a>
be compiled with pthreads otherwise this option is ignored with a
warning. This is meant to reduce packing time on multiprocessor
machines. The required amount of memory for the delta search window
is however multiplied by the number of threads.
Specifying 0 will cause Git to auto-detect the number of CPUs
and set the number of threads accordingly.</p>
</dd>
<dt class="hdlist1">pack.indexVersion</dt>
<dd>
<p>Specify the default pack index version.  Valid values are 1 for
legacy pack index used by Git versions prior to 1.5.2, and 2 for
the new pack index with capabilities for packs larger than 4 GB
as well as proper protection against the repacking of corrupted
packs.  Version 2 is the default.  Note that version 2 is enforced
and this config option is ignored whenever the corresponding pack is
larger than 2 GB.</p>
<div class="paragraph">
<p>If you have an old Git that does not understand the version 2 <code>*.idx</code> file,
cloning or fetching over a non-native protocol (e.g. "http")
that will copy both <code>*.pack</code> file and corresponding <code>*.idx</code> file from the
other side may give you a repository that cannot be accessed with your
older version of Git. If the <code>*.pack</code> file is smaller than 2 GB, however,
you can use <a href="git-index-pack.html">git-index-pack(1)</a> on the *.pack file to regenerate
the <code>*.idx</code> file.</p>
</div>
</dd>
<dt class="hdlist1">pack.packSizeLimit</dt>
<dd>
<p>The maximum size of a pack.  This setting only affects
packing to a file when repacking, i.e. the git:// protocol
is unaffected.  It can be overridden by the <code>--max-pack-size</code>
option of <a href="git-repack.html">git-repack(1)</a>.  Reaching this limit results
in the creation of multiple packfiles.</p>
<div class="paragraph">
<p>Note that this option is rarely useful, and may result in a larger total
on-disk size (because Git will not store deltas between packs) and
worse runtime performance (object lookup within multiple packs is
slower than a single pack, and optimizations like reachability bitmaps
cannot cope with multiple packs).</p>
</div>
<div class="paragraph">
<p>If you need to actively run Git using smaller packfiles (e.g., because your
filesystem does not support large files), this option may help. But if
your goal is to transmit a packfile over a medium that supports limited
sizes (e.g., removable media that cannot store the whole repository),
you are likely better off creating a single large packfile and splitting
it using a generic multi-volume archive tool (e.g., Unix <code>split</code>).</p>
</div>

</dd>
<dt class="hdlist1">pack.useBitmaps</dt>
<dd>
<p>When true, git will use pack bitmaps (if available) when packing
to stdout (e.g., during the server side of a fetch). Defaults to
true. You should not generally need to turn this off unless
you are debugging pack bitmaps.</p>
</dd>
<dt class="hdlist1">pack.useBitmapBoundaryTraversal</dt>
<dd>
<p>When true, Git will use an experimental algorithm for computing
reachability queries with bitmaps. Instead of building up
complete bitmaps for all of the negated tips and then OR-ing
them together, consider negated tips with existing bitmaps as
additive (i.e. OR-ing them into the result if they exist,
ignoring them otherwise), and build up a bitmap at the boundary
instead.</p>
<div class="paragraph">
<p>When using this algorithm, Git may include too many objects as a result
of not opening up trees belonging to certain UNINTERESTING commits. This
inexactness matches the non-bitmap traversal algorithm.</p>
</div>
<div class="paragraph">
<p>In many cases, this can provide a speed-up over the exact algorithm,

the query.</p>

<dt class="hdlist1">pack.useSparse</dt>
<dd>
<p>When true, git will default to using the <em>--sparse</em> option in

algorithm only walks trees that appear in paths that introduce new
objects. This can have significant performance benefits when
computing a pack to send a small change. However, it is possible
that extra objects are added to the pack-file if the included
commits contain certain types of direct renames. Default is
<code>true</code>.</p>
</dd>
<dt class="hdlist1">pack.usePathWalk</dt>

When selecting which commits will receive bitmaps, prefer a
commit at the tip of a reference that is contained in any of
the configured hierarchies.</p>
<div class="paragraph">
<p>Note that setting this configuration to <code>refs/foo/</code> does not mean that
the commits at the tips of <code>refs/foo/bar</code> and <code>refs/foo/baz</code> will
necessarily be selected. This is because commits are selected for
bitmaps from within a series of windows of variable length.</p>
</div>
<div class="paragraph">

<p>When true, git will include a "hash cache" section in the bitmap

delta heuristics, potentially leading to better deltas between
bitmapped and non-bitmapped objects (e.g., when serving a fetch
between an older, bitmapped pack and objects that have been
pushed since the last gc). The downside is that it consumes 4
bytes per object of disk space. Defaults to true.</p>

that the working directory be clean). This mode also comes in handy when
developing inside a VM to test and fix code on different Operating Systems.</p>
</div>

</dd>
<dt class="hdlist1">receive.hideRefs</dt>
<dd>
<p>This variable is the same as <code>transfer.hideRefs</code>, but applies

<p>This is a multi-valued variable that defines reference prefixes
to match the commands in <code>receive-pack</code>.  Commands matching the
prefixes will be executed by an external hook "proc-receive",
instead of the internal <code>execute_commands</code> function.  If this
variable is not defined, the "proc-receive" hook will never be
used, and all commands will be executed by the internal
<code>execute_commands</code> function.</p>
<div class="paragraph">
<p>For example, if this variable is set to "refs/for", pushing to reference

<dt class="hdlist1">remote.&lt;name&gt;.followRemoteHEAD</dt>
<dd>
<p>How <a href="git-fetch.html">git-fetch(1)</a> should handle updates to <code>remotes/</code><em>&lt;name&gt;</em><code>/HEAD</code>
when fetching using the configured refspecs of a remote.
The default value is "create", which will create <code>remotes/</code><em>&lt;name&gt;</em><code>/HEAD</code>
if it exists on the remote, but not locally; this will not touch an
already existing local reference. Setting it to "warn" will print
a message if the remote has a different value than the local one;
in case there is no local reference, it behaves like "create".
A variant on "warn" is "warn-if-not-$branch", which behaves like
"warn", but if <code>HEAD</code> on the remote is <code>$branch</code> it will be silent.
Setting it to "always" will silently update <code>remotes/</code><em>&lt;name&gt;</em><code>/HEAD</code> to
the value on the remote.  Finally, setting it to "never" will never
change or create the local reference.</p>

<ul>
<li>
<p><code>all</code>: Git works with all bare repositories. This is the default in

<div class="paragraph">
<p>If you do not use bare repositories in your workflow, then it may be

</div>
<div class="paragraph">

<dt class="hdlist1">safe.directory</dt>
<dd>
<p>These config entries specify Git-tracked directories that are
considered safe even if they are owned by someone other than the

config of a repository owned by someone else, let alone run its
hooks, and this config setting allows users to specify exceptions,
e.g. for intentionally shared repositories (see the <code>--shared</code>
option in <a href="git-init.html">git-init(1)</a>).</p>
<div class="paragraph">
<p>This is a multi-valued setting, i.e. you can add more than one directory
via <code>git</code> <code>config</code> <code>--add</code>. To reset the list of safe directories (e.g. to
override any such directories specified in the system config), add a
<code>safe.directory</code> entry with an empty value.</p>

<p>The value of this setting is interpolated, i.e. <code>~/</code><em>&lt;path&gt;</em> expands to a
path relative to the home directory and <code>%</code>(<code>prefix</code>)<code>/</code><em>&lt;path&gt;</em> expands to a
path relative to Git&#8217;s (runtime) prefix.</p>
</div>
<div class="paragraph">
<p>To completely opt-out of this security check, set <code>safe.directory</code> to the
string <code>*</code>. This will allow all repositories to be treated as if their
directory was listed in the <code>safe.directory</code> list. If <code>safe.directory=*</code>
is set in system config and you want to re-enable this protection, then
initialize your list with an empty value before listing the repositories
that you deem safe.  Giving a directory with <code>/*</code> appended to it will
allow access to all repositories under the named directory.</p>
</div>
<div class="paragraph">
<p>As explained, Git only allows you to access repositories owned by
yourself, i.e. the user who is running Git, by default.  When Git
is running as <em>root</em> in a non Windows platform that provides sudo,
however, git checks the SUDO_UID environment variable that sudo creates
and will allow access to the uid recorded as its value in addition to
the id from <em>root</em>.
This is to make it easy to perform a common sequence during installation
"make &amp;&amp; sudo make install".  A git process running under <em>sudo</em> runs as
<em>root</em> but the <em>sudo</em> command exports the environment variable to record
which id the original user has.
If that is not what you would prefer and want git to only trust
repositories that are owned by root instead, then you can remove
the <code>SUDO_UID</code> variable from root&#8217;s environment before invoking git.</p>

<dt class="hdlist1">sparse.expectFilesOutsideOfPatterns</dt>
<dd>
<p>Typically with sparse checkouts, files not matching any
sparsity patterns are marked with a SKIP_WORKTREE bit in the
index and are missing from the working tree.  Accordingly, Git
will ordinarily check whether files with the SKIP_WORKTREE bit
are in fact present in the working tree contrary to
expectations.  If Git finds any, it marks those paths as
present by clearing the relevant SKIP_WORKTREE bits.  This
option can be used to tell Git that such
present-despite-skipped files are expected and to stop
checking for them.</p>
<div class="paragraph">
<p>The default is <code>false</code>, which allows Git to automatically recover
from the list of files in the index and working tree falling out of
sync.</p>
</div>
<div class="paragraph">
<p>Set this to <code>true</code> if you are in a setup where some external factor
relieves Git of the responsibility for maintaining the consistency
between the presence of working tree files and sparsity patterns.  For
example, if you have a Git-aware virtual file system that has a robust
mechanism for keeping the working tree and the sparsity patterns up to
date based on access patterns.</p>
</div>

<dt class="hdlist1">splitIndex.maxPercentChange</dt>
<dd>
<p>When the split index feature is used, this specifies the
percent of entries the split index can contain compared to the
total number of entries in both the split index and the shared
index before a new shared index is written.
The value should be between 0 and 100. If the value is 0, then
a new shared index is always written; if it is 100, a new
shared index is never written.
By default, the value is 20, so a new shared index is written
if the number of entries in the split index would be greater
than 20 percent of the total number of entries.

<p>When the split index feature is used, shared index files that
were not modified since the time this variable specifies will
be removed when a new shared index file is created. The value
"now" expires all entries immediately, and "never" suppresses
expiration altogether.
The default value is "2.weeks.ago".
Note that a shared index file is considered modified (for the
purpose of expiration) each time a new split-index file is
either created based on it or read from it.

<p>By default, Git determines the command line arguments to use
based on the basename of the configured SSH command (configured
using the environment variable <code>GIT_SSH</code> or <code>GIT_SSH_COMMAND</code> or
the config setting <code>core.sshCommand</code>). If the basename is
unrecognized, Git will attempt to detect support of OpenSSH
options by first invoking the configured SSH command with the
<code>-G</code> (print configuration) option and will subsequently use
OpenSSH options (if that is successful) or no options besides
the host and remote command (if it fails).</p>
<div class="paragraph">
<p>The config variable <code>ssh.variant</code> can be set to override this detection.
Valid values are <code>ssh</code> (to use OpenSSH options), <code>plink</code>, <code>putty</code>,

<dt class="hdlist1">submodule.&lt;name&gt;.ignore</dt>
<dd>
<p>Defines under what circumstances "git status" and the diff family show
a submodule as modified.
When set to "all" will never consider the submodule modified. It can
nevertheless be staged using the option --force and it will then show up
in the output of status.
When set to "dirty" will ignore all changes to the submodule&#8217;s work tree and
takes only differences between the HEAD of the submodule and the commit
recorded in the superproject into account. "untracked" will additionally
let submodules with modified tracked files in their work tree show up.
When set to "none" (default) it also shows submodules as changed if they have
untracked files in their work tree.
This setting overrides any setting made in .gitmodules for this submodule,
both settings can be overridden on the command line by using the
"--ignore-submodules" option. The <em>git submodule</em> commands are not
affected by this setting.</p>

<p>The git programs will pass the full URL to one another as arguments
on the command-line, meaning the credentials will be exposed to other
unprivileged users on systems that allow them to see the full

documented in procfs(5) allows for configuring this behavior.</p>

and potential security issues like the existence of a .<code>GIT</code> directory

instead be left unreferenced in the repository.</p>
</div>
<div class="paragraph">
<p>Due to the non-quarantine nature of the <code>fetch.fsckObjects</code>
implementation it cannot be relied upon to leave the object store
clean like <code>receive.fsckObjects</code> can.</p>
</div>
<div class="paragraph">
<p>As objects are unpacked they&#8217;re written to the object store, so there
can be cases where malicious objects get introduced even though the
"fetch" failed, only to have a subsequent "fetch" succeed because only
new incoming objects are checked, not those that have already been
written to the object store. That difference in behavior should not be
relied upon. In the future, such objects may be quarantined for
"fetch" as well.</p>
</div>
<div class="paragraph">
<p>For now, the paranoid need to find some way to emulate the quarantine
environment if they&#8217;d like the same protection as "push". E.g. in the
case of an internal mirror do the mirroring in two steps, one to fetch
the untrusted objects, and then do a second "push" (which will use the
quarantine) to another internal repo, and have internal clients
consume this pushed-to repository, or embargo internal fetches and
only allow them once a full "fsck" has run (and no new fetches have
happened in the meantime).</p>

<p>If <a href="git-tag.html">git-tag(1)</a> or <a href="git-commit.html">git-commit(1)</a> is not selecting the
key you want it to automatically when creating a signed tag or
commit, you can override the default selection with this variable.
This option is passed unchanged to gpg&#8217;s --local-user parameter,
so you may specify a key using any method that gpg supports.
If gpg.format is set to <code>ssh</code> this can contain the path to either
your private ssh key or the public key when ssh-agent is used.
Alternatively it can contain a public key prefixed with <code>key::</code>
directly (e.g.: "key::ssh-rsa XXXXXX identifier"). The private key
needs to be available via ssh-agent. If not set Git will call
gpg.ssh.defaultKeyCommand (e.g.: "ssh-add -L") and try to use the
first key available. For backward compatibility, a raw key which
begins with "ssh-", such as "ssh-rsa XXXXXX identifier", is treated
as "key::ssh-rsa XXXXXX identifier", but this form is deprecated;
use the <code>key::</code> form instead.</p>
</dd>
<dt class="hdlist1">versionsort.prereleaseSuffix (deprecated)</dt>
<dd>
<p>Deprecated alias for <code>versionsort.suffix</code>.  Ignored if
<code>versionsort.suffix</code> is set.</p>
</dd>
<dt class="hdlist1">versionsort.suffix</dt>
<dd>
<p>Even when version sort is used in <a href="git-tag.html">git-tag(1)</a>, tagnames
with the same base version but different suffixes are still sorted
lexicographically, resulting e.g. in prerelease tags appearing
after the main release (e.g. "1.0-rc1" after "1.0").  This
variable can be specified to determine the sorting order of tags
with different suffixes.</p>
<div class="paragraph">
<p>By specifying a single suffix in this variable, any tagname containing
that suffix will appear before the corresponding main release.  E.g. if
the variable is set to "-rc", then all "1.0-rcX" tags will appear before
"1.0".  If specified multiple times, once per suffix, then the order of
suffixes in the configuration will determine the sorting order of tagnames
with those suffixes.  E.g. if "-pre" appears before "-rc" in the
configuration, then all "1.0-preX" tags will be listed before any
"1.0-rcX" tags.  The placement of the main release tag relative to tags
with various suffixes can be determined by specifying the empty suffix
among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck", and
"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
are listed first, followed by "v4.8", then "v4.8-ckX" and finally
"v4.8-bfsX".</p>
</div>
<div class="paragraph">
<p>If more than one suffix matches the same tagname, then that tagname will
be sorted according to the suffix which starts at the earliest position in
the tagname.  If more than one different matching suffix starts at
that earliest position, then that tagname will be sorted according to the
longest of those suffixes.
The sorting order between different suffixes is undefined if they are
in multiple config files.</p>
</div>
</dd>
<dt class="hdlist1">web.browser</dt>
<dd>
<p>Specify a web browser that may be used by some commands.
Currently only <a href="git-instaweb.html">git-instaweb(1)</a> and <a href="git-help.html">git-help(1)</a>
may use it.</p>
</dd>
<dt class="hdlist1">windows.appendAtomically</dt>
<dd>
<p>By default, append atomic API is used on windows. But it works only with
local disk files, if you&#8217;re working on a network file system, you should
set it false to turn it off.</p>
</dd>
<dt class="hdlist1"><code>worktree.guessRemote</code></dt>
<dd>
<p>If no branch is specified and neither <code>-b</code> nor <code>-B</code> nor
<code>--detach</code> is used, then <code>git</code> <code>worktree</code> <code>add</code> defaults to
creating a new branch from HEAD.  If <code>worktree.guessRemote</code> is
set to true, <code>worktree</code> <code>add</code> tries to find a remote-tracking
branch whose name uniquely matches the new branch name.  If
such a branch exists, it is checked out and set as "upstream"
for the new branch.  If no such match can be found, it falls
back to creating a new branch from the current <code>HEAD</code>.</p>
</dd>
<dt class="hdlist1"><code>worktree.useRelativePaths</code></dt>
<dd>
<p>Link worktrees using relative paths (when "<code>true</code>") or absolute
paths (when "<code>false</code>"). This is particularly useful for setups
where the repository and worktrees may be moved between
different locations or environments. Defaults to "<code>false</code>".</p>
<div class="paragraph">
<p>Note that setting <code>worktree.useRelativePaths</code> to "<code>true</code>" implies enabling the
<code>extensions.relativeWorktrees</code> config (see <a href="git-config.html">git-config(1)</a>),
thus making it incompatible with older versions of Git.</p>
