.SH "DESCRIPTION"
.sp
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\&.
.sp
Multiple lines can be added to an option by using the \fB\-\-add\fR option\&. If you want to update or unset an option which can occur on multiple lines, a \fBvalue\-pattern\fR (which is an extended regular expression, unless the \fB\-\-fixed\-value\fR 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 \fBnot\fR match the pattern, just prepend a single exclamation mark in front (see also the section called \(lqEXAMPLES\(rq), but note that this only works when the \fB\-\-fixed\-value\fR option is not in use\&.
.sp
The \fB\-\-type=<type>\fR option instructs \fIgit config\fR to ensure that incoming and outgoing values are canonicalize\-able under the given <type>\&. If no \fB\-\-type=<type>\fR is given, no canonicalization will be performed\&. Callers may unset an existing \fB\-\-type\fR specifier with \fB\-\-no\-type\fR\&.
.sp
When reading, the values are read from the system, global and repository local configuration files by default, and options \fB\-\-system\fR, \fB\-\-global\fR, \fB\-\-local\fR, \fB\-\-worktree\fR and \fB\-\-file <filename>\fR can be used to tell the command to read from only that location (see the section called \(lqFILES\(rq)\&.
.sp
When writing, the new value is written to the repository local configuration file by default, and options \fB\-\-system\fR, \fB\-\-global\fR, \fB\-\-worktree\fR, \fB\-\-file <filename>\fR can be used to tell the command to write to that location (you can say \fB\-\-local\fR but that is the default)\&.
.sp
This command will fail with non\-zero status upon error\&. Some exit codes are:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c

.sp
A list of all available configuration variables can be obtained using the \fBgit help \-\-config\fR command\&.
.SH "OPTIONS"
.PP
\-\-replace\-all
.RS 4
Default behavior is to replace at most one line\&. This replaces all lines matching the key (and optionally the
\fBvalue\-pattern\fR)\&.
.RE
.PP
\-\-add
.RS 4
Adds a new line to the option without altering any existing values\&. This is the same as providing
\fI^$\fR
as the
\fBvalue\-pattern\fR
in
\fB\-\-replace\-all\fR\&.
.RE
.PP
\-\-get
.RS 4
Get the value for a given key (optionally filtered by a regex matching the value)\&. Returns error code 1 if the key was not found and the last value if multiple key values were found\&.
.RE
.PP
\-\-get\-all
.RS 4
Like get, but returns all values for a multi\-valued key\&.
.RE
.PP
\-\-get\-regexp
.RS 4
Like \-\-get\-all, but interprets the name as a regular expression and writes out the key names\&. Regular expression matching is currently case\-sensitive and done against a canonicalized version of the key in which section and variable names are lowercased, but subsection names are not\&.
.RE
.PP
\-\-get\-urlmatch <name> <URL>
.RS 4
When given a two\-part name section\&.key, the value for section\&.<URL>\&.key whose <URL> part matches the best to the given URL is returned (if no such key exists, the value for section\&.key is used as a fallback)\&. When given just the section as name, do so for all the keys in the section and list them\&. Returns error code 1 if no value is found\&.
.RE
.PP
\-\-global
.RS 4
For writing options: write to global
\fB~/\&.gitconfig\fR
file rather than the repository
\fB\&.git/config\fR, write to
\fB$XDG_CONFIG_HOME/git/config\fR
file if this file exists and the
\fB~/\&.gitconfig\fR
file doesn\(cqt\&.
.sp
For reading options: read only from global
\fB~/\&.gitconfig\fR
and from
\fB$XDG_CONFIG_HOME/git/config\fR
rather than from all available files\&.
.sp
See also
the section called \(lqFILES\(rq\&.
.RE

\fB\&.git/config\fR
rather than from all available files\&.
.sp
See also
the section called \(lqFILES\(rq\&.
.RE
.PP
\-\-worktree
.RS 4
Similar to
\fB\-\-local\fR
except that
\fB$GIT_DIR/config\&.worktree\fR
is read from or written to if
\fBextensions\&.worktreeConfig\fR
is enabled\&. If not it\(cqs the same as
\fB\-\-local\fR\&. Note that
\fB$GIT_DIR\fR
is equal to
\fB$GIT_COMMON_DIR\fR
for the main working tree, but is of the form
\fB$GIT_DIR/worktrees/<id>/\fR
for other working trees\&. See
\fBgit-worktree\fR(1)
to learn how to enable
\fBextensions\&.worktreeConfig\fR\&.
.RE
.PP
\-f <config\-file>, \-\-file <config\-file>
.RS 4
For writing options: write to the specified file rather than the repository
\fB\&.git/config\fR\&.

See also
the section called \(lqFILES\(rq\&.
.RE
.PP
\-\-blob <blob>
.RS 4
Similar to
\fB\-\-file\fR
but use the given blob instead of a file\&. E\&.g\&. you can use
\fImaster:\&.gitmodules\fR
to read values from the file
\fI\&.gitmodules\fR
in the master branch\&. See "SPECIFYING REVISIONS" section in
\fBgitrevisions\fR(7)
for a more complete list of ways to spell blob names\&.
.RE
.PP
\-\-remove\-section
.RS 4
Remove the given section from the configuration file\&.
.RE
.PP
\-\-rename\-section
.RS 4
Rename the given section to a new name\&.
.RE
.PP
\-\-unset
.RS 4
Remove the line matching the key from config file\&.
.RE
.PP
\-\-unset\-all
.RS 4

.RE
.PP
\-l, \-\-list
.RS 4
List all variables set in config file, along with their values\&.
.RE
.PP
\-\-fixed\-value
.RS 4
When used with the
\fBvalue\-pattern\fR
argument, treat
\fBvalue\-pattern\fR
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 the
\fBvalue\-pattern\fR\&.
.RE
.PP
\-\-type <type>

System\-wide configuration file\&.
.RE
.PP

.RS 4
User\-specific configuration files\&. When the XDG_CONFIG_HOME environment variable is not set or empty, $HOME/\&.config/ is used as $XDG_CONFIG_HOME\&.
.sp
These are also called "global" configuration files\&. If both files exist, both files are read in the order given above\&.

.RE
.sp
You may also provide additional configuration parameters when running any git command by using the \fB\-c\fR option\&. See \fBgit\fR(1) for details\&.
.sp
Options will be read from all of these files that are available\&. If the global or the system\-wide configuration files are missing or unreadable they will be ignored\&. If the repository configuration file is missing or unreadable, \fIgit config\fR will exit with a non\-zero error code\&. An error message is produced if the file is unreadable, but not if it is missing\&.
.sp
The files are read in the order given above, with last value found taking precedence over values read earlier\&. When multiple values are taken then all values of a key from all files will be used\&.
.sp
By default, options are only written to the repository specific configuration file\&. Note that this also affects options like \fB\-\-replace\-all\fR and \fB\-\-unset\fR\&. \fB\fIgit config\fR\fR\fB will only ever change one file at a time\fR\&.
.sp
You can limit which configuration sources are read from or written to by specifying the path of a file with the \fB\-\-file\fR option, or by specifying a configuration scope with \fB\-\-system\fR, \fB\-\-global\fR, \fB\-\-local\fR, or \fB\-\-worktree\fR\&. For more, see the section called \(lqOPTIONS\(rq above\&.

.sp
With the exception of \fIcommand\fR, each scope corresponds to a command line option: \fB\-\-system\fR, \fB\-\-global\fR, \fB\-\-local\fR, \fB\-\-worktree\fR\&.
.sp
When reading options, specifying a scope will only read options from the files within that scope\&. When writing options, specifying a scope will write to the files within that scope (instead of the repository specific configuration file)\&. See the section called \(lqOPTIONS\(rq above for a complete description\&.
.sp
Most configuration options are respected regardless of the scope it is defined in, but some options are only respected in certain scopes\&. See the respective option\(cqs documentation for the full details\&.
.SS "Protected configuration"
.sp
Protected configuration refers to the \fIsystem\fR, \fIglobal\fR, and \fIcommand\fR scopes\&. For security reasons, certain options are only respected when they are specified in protected configuration, and ignored otherwise\&.
.sp
Git treats these scopes as if they are controlled by the user or a trusted administrator\&. This is because an attacker who controls these scopes can do substantial harm without using Git, so it is assumed that the user\(cqs environment protects these scopes against attackers\&.

The config pairs are zero\-indexed\&. Any missing key or value is treated as an error\&. An empty GIT_CONFIG_COUNT is treated the same as GIT_CONFIG_COUNT=0, namely no pairs are processed\&. These environment variables will override values in configuration files, but will be overridden by any explicit options passed via
\fBgit \-c\fR\&.

.SH "CONFIGURATION FILE"
.sp
The Git configuration file contains a number of variables that affect the Git commands\*(Aq behavior\&. The files \fB\&.git/config\fR and optionally \fBconfig\&.worktree\fR (see the "CONFIGURATION FILE" section of \fBgit-worktree\fR(1)) in each repository are used to store the configuration for that repository, and \fB$HOME/\&.gitconfig\fR is used to store a per\-user configuration as fallback values for the \fB\&.git/config\fR file\&. The file \fB/etc/gitconfig\fR can be used to store a system\-wide default configuration\&.
.sp
The configuration variables are used by both the Git plumbing and the porcelains\&. 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 \fB\-\fR, and must start with an alphabetic character\&. Some variables may appear multiple times; we say then that the variable is multivalued\&.
.SS "Syntax"
.sp
The syntax is fairly flexible and permissive; whitespaces are mostly ignored\&. The \fI#\fR and \fI;\fR characters begin comments to the end of line, blank lines are ignored\&.
.sp
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, \fB\-\fR and \fB\&.\fR 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\&.
.sp
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:
.sp
.if n \{\
.RS 4
.\}
.nf
        [section "subsection"]
.fi
.if n \{\
.RE
.\}
.sp
.sp
Subsection names are case sensitive and can contain any characters except newline and the null byte\&. Doublequote \fB"\fR and backslash can be included by escaping them as \fB\e"\fR and \fB\e\e\fR, respectively\&. Backslashes preceding other characters are dropped when reading; for example, \fB\et\fR is read as \fBt\fR and \fB\e0\fR is read as \fB0\fR\&. Section headers cannot span multiple lines\&. Variables may belong directly to a section or to a given subsection\&. You can have \fB[section]\fR if you have \fB[section "subsection"]\fR, but you don\(cqt need to\&.
.sp
There is also a deprecated \fB[section\&.subsection]\fR 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\&.
.sp
All the other lines (and the remainder of the line after the section header) are recognized as setting variables, in the form \fIname = value\fR (or just \fIname\fR, 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 \fB\-\fR, and must start with an alphabetic character\&.
.sp
A line that defines a value can be continued to the next line by ending it with a \fB\e\fR; the backslash and the end\-of\-line are stripped\&. Leading whitespaces after \fIname =\fR, the remainder of the line after the first comment character \fI#\fR or \fI;\fR, and trailing whitespaces of the line are discarded unless they are enclosed in double quotes\&. Internal whitespaces within the value are retained verbatim\&.
.sp
Inside double quotes, double quote \fB"\fR and backslash \fB\e\fR characters must be escaped: use \fB\e"\fR for \fB"\fR and \fB\e\e\fR for \fB\e\fR\&.
.sp
The following escape sequences (beside \fB\e"\fR and \fB\e\e\fR) are recognized: \fB\en\fR for newline character (NL), \fB\et\fR for horizontal tabulation (HT, TAB) and \fB\eb\fR for backspace (BS)\&. Other char escape sequences (including octal escape sequences) are invalid\&.
.SS "Includes"
.sp
The \fBinclude\fR and \fBincludeIf\fR sections allow you to include config directives from another source\&. These sections behave identically to each other with the exception that \fBincludeIf\fR sections may be ignored if their condition does not evaluate to true; see "Conditional includes" below\&.
.sp
You can include a config file from another by setting the special \fBinclude\&.path\fR (or \fBincludeIf\&.*\&.path\fR) 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\&.
.sp
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\&.
.SS "Conditional includes"
.sp
You can include a config file from another conditionally by setting a \fBincludeIf\&.<condition>\&.path\fR variable to the name of the file to be included\&.
.sp
The condition starts with a keyword followed by a colon and some data whose format and meaning depends on the keyword\&. Supported keywords are:
.PP
\fBgitdir\fR
.RS 4
The data that follows the keyword
\fBgitdir:\fR
is used as a glob pattern\&. If the location of the \&.git directory matches the pattern, the include condition is met\&.
.sp
The \&.git location may be auto\-discovered, or come from
\fB$GIT_DIR\fR
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\&.
.sp
The pattern can contain standard globbing wildcards and two additional ones,
\fB**/\fR
and
\fB/**\fR, that can match multiple path components\&. Please refer to
\fBgitignore\fR(5)
for details\&. For convenience:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
If the pattern starts with
\fB~/\fR,
\fB~\fR
will be substituted with the content of the environment variable
\fBHOME\fR\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

\fB\&./\fR, it is replaced with the directory containing the current config file\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
If the pattern does not start with either
\fB~/\fR,
\fB\&./\fR
or
\fB/\fR,
\fB**/\fR
will be automatically prepended\&. For example, the pattern
\fBfoo/bar\fR
becomes
\fB**/foo/bar\fR
and would match
\fB/any/path/to/foo/bar\fR\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
If the pattern ends with
\fB/\fR,
\fB**\fR
will be automatically added\&. For example, the pattern
\fBfoo/\fR
becomes
\fBfoo/**\fR\&. In other words, it matches "foo" and everything inside, recursively\&.
.RE
.RE
.PP
\fBgitdir/i\fR
.RS 4
This is the same as
\fBgitdir\fR
except that matching is done case\-insensitively (e\&.g\&. on case\-insensitive file systems)
.RE
.PP
\fBonbranch\fR
.RS 4
The data that follows the keyword
\fBonbranch:\fR
is taken to be a pattern with standard globbing wildcards and two additional ones,
\fB**/\fR
and
\fB/**\fR, 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\&.
.sp
If the pattern ends with
\fB/\fR,
\fB**\fR
will be automatically added\&. For example, the pattern
\fBfoo/\fR
becomes
\fBfoo/**\fR\&. In other words, it matches all branches that begin with
\fBfoo/\fR\&. This is useful if your branches are organized hierarchically and you would like to apply a configuration to all the branches in that hierarchy\&.
.RE
.PP
\fBhasconfig:remote\&.*\&.url:\fR
.RS 4
The data that follows this keyword is taken to be a pattern with standard globbing wildcards and two additional ones,
\fB**/\fR
and
\fB/**\fR, 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\&.
.sp
Files included by this option (directly or indirectly) are not allowed to contain remote URLs\&.
.sp
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)\&.
.sp
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\&.
.RE

A few more notes on matching via \fBgitdir\fR and \fBgitdir/i\fR:

.sp -1

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

Both the symlink & realpath versions of paths will be matched outside of
\fB$GIT_DIR\fR\&. E\&.g\&. if ~/git is a symlink to /mnt/storage/git, both
\fBgitdir:~/git\fR
and
\fBgitdir:/mnt/storage/git\fR
will match\&.
.sp
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\&.

.PP
boolean
.RS 4
When a variable is said to take a boolean value, many synonyms are accepted for
\fItrue\fR

\fIfalse\fR; these are all case\-insensitive\&.
.PP
true
.RS 4
Boolean true literals are
\fByes\fR,
\fBon\fR,
\fBtrue\fR, and
\fB1\fR\&. Also, a variable defined without
\fB= <value>\fR
is taken as true\&.
.RE

Boolean false literals are
\fBno\fR,
\fBoff\fR,
\fBfalse\fR,
\fB0\fR
and the empty string\&.
.sp

\fB\-\-type=bool\fR

.PP
integer
.RS 4

\fBk\fR,
\fBM\fR,\&... to mean "scale the number by 1024", "by 1024x1024", etc\&.
.RE
.PP
color
.RS 4
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\&.
.sp
The basic colors accepted are
\fBnormal\fR,
\fBblack\fR,
\fBred\fR,
\fBgreen\fR,
\fByellow\fR,
\fBblue\fR,
\fBmagenta\fR,
\fBcyan\fR,
\fBwhite\fR
and
\fBdefault\fR\&. The first color given is the foreground; the second is the background\&. All the basic colors except
\fBnormal\fR
and
\fBdefault\fR
have a bright variant that can be specified by prefixing the color with
\fBbright\fR, like
\fBbrightred\fR\&.
.sp
The color
\fBnormal\fR
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")\&.
.sp
The color
\fBdefault\fR
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"\&.
.sp
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
\fB#ff0ab3\fR\&.
.sp
The accepted attributes are
\fBbold\fR,
\fBdim\fR,
\fBul\fR,
\fBblink\fR,
\fBreverse\fR,
\fBitalic\fR, and
\fBstrike\fR
(for crossed\-out or "strikethrough" letters)\&. The position of any attributes with respect to the colors (before, after, or in between), doesn\(cqt matter\&. Specific attributes may be turned off by prefixing them with
\fBno\fR
or
\fBno\-\fR
(e\&.g\&.,
\fBnoreverse\fR,
\fBno\-ul\fR, etc)\&.
.sp
The pseudo\-attribute
\fBreset\fR
resets all colors and attributes before applying the specified coloring\&. For example,
\fBreset green\fR
will result in a green foreground and default background without any active attributes\&.
.sp
An empty color string produces no color effect at all\&. This can be used to avoid coloring specific elements without disabling color entirely\&.
.sp
For git\(cqs pre\-defined color slots, the attributes are meant to be reset at the beginning of each item in the colored output\&. So setting
\fBcolor\&.decorate\&.branch\fR
to
\fBblack\fR
will paint that branch name in a plain
\fBblack\fR, even if the previous thing on the same output line (e\&.g\&. opening parenthesis before the list of branch names in
\fBlog \-\-decorate\fR
output) is set to be painted with
\fBbold\fR
or some other attribute\&. However, custom log formats may do more complicated and layered coloring, and the negated forms may be useful there\&.
.RE
.PP
pathname
.RS 4
A variable that takes a pathname value can be given a string that begins with "\fB~/\fR" or "\fB~user/\fR", and the usual tilde expansion happens to such a string:
\fB~/\fR
is expanded to the value of
\fB$HOME\fR, and
\fB~user/\fR
to the specified user\(cqs home directory\&.
.sp
If a path starts with
\fB%(prefix)/\fR, the remainder is interpreted as a path relative to Git\(cqs "runtime prefix", i\&.e\&. relative to the location where Git itself was installed\&. For example,
\fB%(prefix)/bin/\fR
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
\fInot\fR
be expanded, it needs to be prefixed by
\fB\&./\fR, like so:
\fB\&./%(prefix)/bin\fR\&.

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\&.

core\&.safecrlf
.RS 4
If true, makes Git check if converting
\fBCRLF\fR
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
\fBcore\&.autocrlf\fR, 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\&.
.sp
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\&.
.sp
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\&.
.sp
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\&.
.sp
Note, this safety check does not mean that a checkout will generate a file identical to the original file for a different setting of
\fBcore\&.eol\fR
and
\fBcore\&.autocrlf\fR, but only for the current one\&. For example, a text file with
\fBLF\fR
would be accepted with
\fBcore\&.eol=lf\fR
and could later be checked out with
\fBcore\&.eol=crlf\fR, in which case the resulting file would contain
\fBCRLF\fR, although the original file contained
\fBLF\fR\&. However, in both work trees the line endings would be consistent, that is either all
\fBLF\fR

\fBCRLF\fR, but never mixed\&. A file with mixed line endings would be reported by the
\fBcore\&.safecrlf\fR

By default Git will look for your hooks in the
\fB$GIT_DIR/hooks\fR
directory\&. Set this to different path, e\&.g\&.

The path can be either absolute or relative\&. A relative path is taken as relative to the directory where the hooks are run (see the "DESCRIPTION" section of
\fBgithooks\fR(5))\&.

This configuration variable is useful in cases where you\(cqd like to centrally configure your Git hooks instead of configuring them on a per\-repository basis, or as a more flexible and centralized alternative to having an

When the

\fBLESS\fR
environment variable is set, Git does not change it at all)\&. If you want to selectively override Git\(cqs default setting for
\fBLESS\fR, you can set
\fBcore\&.pager\fR

\fBless \-S\fR\&. This will be passed to the shell by Git, which will translate the final command to
\fBLESS=FRX less \-S\fR\&. The environment does not set the
\fBS\fR
option but the command line does, instructing less to truncate long lines\&. Similarly, setting
\fBcore\&.pager\fR
to
\fBless \-+F\fR
will deactivate the

Compute the dirstat numbers by counting the lines that have been removed from the source, or added to the destination\&. This ignores the amount of pure code movements within a file\&.

In general, it is better to enumerate existing objects with problems with

gpg\&.ssh\&.defaultKeyCommand
.RS 4
This command that 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
\fBkey::\fR
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

gpg\&.ssh\&.allowedSignersFile

See ssh\-keygen(1) "ALLOWED SIGNERS" for details\&. The principal is only used to identify the key and is available when verifying a signature\&.
.sp
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
\fBfully\fR
when the public key is present in the allowedSignersFile\&. Otherwise the trust level is
\fBundefined\fR
and git verify\-commit/tag will fail\&.
.sp
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\&.
.sp
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\&.
.sp
Since OpensSSH 8\&.8 this file allows specifying a key lifetime using valid\-after & valid\-before options\&. Git will mark signatures as valid if the signing key was valid at the time of the signature\(cqs creation\&. This allows users to change a signing key without invalidating all previously made signatures\&.

The list above is ordered by decreasing precedence; a URL that matches a config key\(cqs path is preferred to one that matches its user name\&. For example, if the URL is

\fBhttps://example\&.com/foo\fR

\fBhttps://user@example\&.com\fR\&.
.sp
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\&.

If merge is called without any commit argument, merge the upstream branches configured for the current branch by using their last observed values stored in their remote\-tracking branches\&. The values of the

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), as well as worse runtime performance (object lookup within multiple packs is slower than a single pack, and optimizations like reachability bitmaps cannot cope with multiple packs)\&.

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

When true, Git will use an experimental algorithm for computing reachability queries with bitmaps\&.

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\&.

.sp
If you do not use bare repositories in your workflow, then it may be beneficial to set
\fBsafe\&.bareRepository\fR
to
\fBexplicit\fR
in your global config\&. This will protect you from attacks that involve cloning a repository that contains a bare repository and running a Git command within that directory\&.

.RE

safe\&.directory
.RS 4
These config entries specify Git\-tracked directories that are considered safe even if they are owned by someone other than the current user\&. By default, Git will refuse to even parse a Git 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
\fB\-\-shared\fR
option in
\fBgit-init\fR(1))\&.
.sp
This is a multi\-valued setting, i\&.e\&. you can add more than one directory via
\fBgit config \-\-add\fR\&. To reset the list of safe directories (e\&.g\&. to override any such directories specified in the system config), add a
\fBsafe\&.directory\fR
entry with an empty value\&.
.sp
This config setting is only respected in protected configuration (see
the section called \(lqSCOPES\(rq)\&. This prevents the untrusted repository from tampering with this value\&.
.sp
The value of this setting is interpolated, i\&.e\&.
\fB~/<path>\fR
expands to a path relative to the home directory and
\fB%(prefix)/<path>\fR
expands to a path relative to Git\(cqs (runtime) prefix\&.
.sp
To completely opt\-out of this security check, set
\fBsafe\&.directory\fR
to the string
\fB*\fR\&. This will allow all repositories to be treated as if their directory was listed in the
\fBsafe\&.directory\fR
list\&. If
\fBsafe\&.directory=*\fR
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\&.
.sp
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
\fIroot\fR
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
\fIroot\fR\&. This is to make it easy to perform a common sequence during installation "make && sudo make install"\&. A git process running under
\fIsudo\fR
runs as
\fIroot\fR
but the
\fIsudo\fR
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
\fBSUDO_UID\fR
variable from root\(cqs environment before invoking git\&.

sparse\&.expectFilesOutsideOfPatterns
.RS 4
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\&.
.sp
The default is
\fBfalse\fR, which allows Git to automatically recover from the list of files in the index and working tree falling out of sync\&.
.sp
Set this to
\fBtrue\fR
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\&.

When set, the fetch or receive will abort in the case of a malformed object or a link to a nonexistent object\&. In addition, various other issues are checked for, including legacy issues (see

On the receiving side, failing fsckObjects will make those objects unreachable, see "QUARANTINE ENVIRONMENT" in

Due to the non\-quarantine nature of the

As objects are unpacked they\(cqre 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\&.

For now, the paranoid need to find some way to emulate the quarantine environment if they\(cqd like the same protection as "push"\&.

When more than one insteadOf strings match a given URL, the longest match is used\&.
.sp
Note that any protocol restrictions will be applied to the rewritten URL\&. If the rewrite changes the URL to use a custom protocol or remote helper, you may need to adjust the
\fBprotocol\&.*\&.allow\fR
config to permit the request\&. In particular, protocols you expect to use for submodules must be set to
\fBalways\fR

\fBuser\fR\&. See the description of

Any URL that starts with this value will not be pushed to; instead, it will be rewritten to start with <base>, and the resulting URL will be pushed to\&. In cases where some site serves a large number of repositories, and serves them with multiple access methods, some of which do not allow push, this feature allows people to specify a pull\-only URL and have Git automatically use an appropriate URL to push, even for a never\-before\-seen repository on the site\&. When more than one pushInsteadOf strings match a given URL, the longest match is used\&. If a remote has an explicit pushurl, Git will ignore this setting for that remote\&.

If
\fBgit-tag\fR(1)

\fBgit-commit\fR(1)
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\(cqs \-\-local\-user parameter, so you may specify a key using any method that gpg supports\&. If gpg\&.format is set to
\fBssh\fR
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
\fBkey::\fR
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
\fBkey::\fR

versionsort\&.suffix
.RS 4
Even when version sort is used in
\fBgit-tag\fR(1), 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\&.
.sp
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"\&.
.sp
If more than one suffixes match 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 suffixes start 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\&.
