[section "subsection"]

The .git location may be auto-discovered, or come from $GIT_DIR 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.

The pattern can contain standard globbing wildcards and two additional ones, **/ and /**, that can match multiple path components. Please refer to gitignore(5) for details. For convenience:

If the pattern ends with /, ** will be automatically added. For example, the pattern foo/ becomes foo/**. In other words, it matches all branches that begin with foo/. This is useful if your branches are organized hierarchically and you would like to apply a configuration to all the branches in that hierarchy.

Files included by this option (directly or indirectly) are not allowed to contain remote URLs.

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).

As for the naming of this keyword, it is for forwards compatibiliy with a naming scheme that supports more variable-based include conditions, but currently Git only supports the exact keyword described above.

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.

true

false

The basic colors accepted are normal, black, red, green, yellow, blue, magenta, cyan, white and default. The first color given is the foreground; the second is the background. All the basic colors except normal and default have a bright variant that can be specified by prefixing the color with bright, like brightred.

The color normal 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").

The color default 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".

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.

The accepted attributes are bold, dim, ul, blink, reverse, italic, and strike (for crossed-out or "strikethrough" letters). The position of any attributes with respect to the colors (before, after, or in between), doesn’t matter. Specific attributes may be turned off by prefixing them with no or no- (e.g., noreverse, no-ul, etc).

The pseudo-attribute reset resets all colors and attributes before applying the specified coloring. For example, reset green will result in a green foreground and default background without any active attributes.

An empty color string produces no color effect at all. This can be used to avoid coloring specific elements without disabling color entirely.

For git’s pre-defined color slots, the attributes are meant to be reset at the beginning of each item in the colored output. So setting color.decorate.branch to black will paint that branch name in a plain black, even if the previous thing on the same output line (e.g. opening parenthesis before the list of branch names in log --decorate output) is set to be painted with bold or some other attribute. However, custom log formats may do more complicated and layered coloring, and the negated forms may be useful there.

If a path starts with %(prefix)/, the remainder is interpreted as a path relative to Git’s "runtime prefix", i.e. relative to the location where Git itself was installed. For example, %(prefix)/bin/ 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 not be expanded, it needs to be prefixed by ./, like so: ./%(prefix)/bin.

Some filesystems lose the executable bit when a file that is marked as executable is checked out, or checks out a non-executable file with executable bit on. git-clone(1) or git-init(1) probe the filesystem to see if it handles the executable bit correctly and this variable is automatically set as necessary.

A repository, however, may be on a filesystem that handles the filemode correctly, and this variable is set to true when created, but later may be made accessible from another environment that loses the filemode (e.g. exporting ext4 via CIFS mount, visiting a Cygwin created repository with Git for Windows or Eclipse). In such a case it may be necessary to set this variable to false. See git-update-index(1).

The default is true (when core.filemode is not specified in the config file).

The default is false, except git-clone(1) or git-init(1) will probe and set core.ignoreCase true if appropriate when the repository is created.

Git relies on the proper configuration of this variable for your operating and file system. Modifying this value may result in unexpected behavior.

Like hook-based file system monitors, the built-in file system monitor can speed up Git commands that need to refresh the Git index (e.g. git status) in a working directory with many files. The built-in monitor eliminates the need to install and maintain an external third-party tool.

The built-in file system monitor is currently available only on a limited set of supported platforms. Currently, this includes Windows and MacOS.

Otherwise, this variable contains the pathname of the "fsmonitor"
hook command.

This hook command is used to identify all files that may have changed since the requested date/time. This information is used to speed up git by avoiding unnecessary scanning of files that have not changed.

See the "fsmonitor-watchman" section of githooks(5).

Note that if you concurrently use multiple versions of Git, such as one version on the command line and another version in an IDE tool, that the definition of core.fsmonitor was extended to 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 file system monitor.

There are currently versions 1 and 2. When this is not set, version 2 will be tried first and if it fails then version 1 will be tried. Version 1 uses a timestamp as input to determine which files have changes since that time but some monitors like Watchman have race conditions when used with a timestamp. Version 2 uses an opaque string so that the monitor can return something that can be used to determine what files have changed without race conditions.

There are implementations of Git that do not leave usable values in some fields (e.g. JGit); by excluding these fields from the comparison, the minimal mode may help interoperability when the same repository is used by these other systems at the same time.

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.

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.

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.

Note, this safety check does not mean that a checkout will generate a file identical to the original file for a different setting of core.eol and core.autocrlf, but only for the current one. For example, a text file with LF would be accepted with core.eol=lf and could later be checked out with core.eol=crlf, in which case the resulting file would contain CRLF, although the original file contained LF. However, in both work trees the line endings would be consistent, that is either all LF or all CRLF, but never mixed. A file with mixed line endings would be reported by the core.safecrlf mechanism.

The default is true, except git-clone(1) or git-init(1) will probe and set core.symlinks false if appropriate when the repository is created.

Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies universally, without the special "for" handling).

The special string none can be used as the proxy command to specify that no proxy be used for a given domain pattern. This is useful for excluding servers inside a firewall from proxy use, while defaulting to a common proxy for external domains.

When files are modified outside of Git, the user will need to stage the modified files explicitly (e.g. see Examples section in git-update-index(1)). Git will not normally detect changes to those files.

This is useful on systems where lstat() calls are very slow, such as CIFS/Microsoft Windows.

False by default.

Note that you cannot generally put git for-each-ref directly into the config value, as it does not take a repository path as an argument (but you can wrap the command above in a shell script).

This setting is automatically guessed by git-clone(1) or git-init(1) when the repository was created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true).

Note that this variable is honored even when set in a configuration file in a ".git" subdirectory of a directory and its value differs from the latter directory (e.g. "/path/to/.git/config" has core.worktree set to "/different/path"), which is most likely a misconfiguration. Running Git commands in the "/path/to" directory will still use "/different/path" as the root of the work tree and can cause confusion unless you know what you are doing (e.g. you are creating a read-only snapshot of the same index to a location different from the repository’s usual working tree).

This information can be used to determine what commit was the tip of a branch "2 days ago".

This value is true by default in a repository that has a working directory associated with it, and false by default in a bare repository.

Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should be reasonable for all users/operating systems. You probably do not need to adjust this value.

Common unit suffixes of k, m, or g are supported.

Default is 256 MiB on 32 bit platforms and 32 TiB (effectively unlimited) on 64 bit platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

Common unit suffixes of k, m, or g are supported.

Default is 96 MiB on all platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

Common unit suffixes of k, m, or g are supported.

Files above the configured limit will be:

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 githooks(5)).

This configuration variable is useful in cases where you’d 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 init.templateDir where you’ve changed default hooks.

If set to "auto", git-commit would select a character that is not the beginning character of any line in existing commit messages.

When the LESS environment variable is unset, Git sets it to FRX (if LESS environment variable is set, Git does not change it at all). If you want to selectively override Git’s default setting for LESS, you can set core.pager to e.g. less -S. This will be passed to the shell by Git, which will translate the final command to LESS=FRX less -S. The environment does not set the S option but the command line does, instructing less to truncate long lines. Similarly, setting core.pager to less -+F will deactivate the F option specified by the environment from the command-line, deactivating the "quit if one screen" behavior of less. One can specifically activate some flags for particular commands: for example, setting pager.blame to less -S enables line truncation only for git blame.

Likewise, when the LV environment variable is unset, Git sets it to -c. You can override this setting by exporting LV with another value or setting core.pager to lv +c.

When this configuration is encountered, the set of components starts with the platform default value, disabled components are removed, and additional components are added. none resets the state so that the platform default is ignored.

The empty string resets the fsync configuration to the platform default. The default on most platforms is equivalent to core.fsync=committed,-loose-object, which has good performance, but risks losing recent work in the event of an unclean system shutdown.

This setting affects data added to the Git repository in loose-object form. When set to true, Git will issue an fsync or similar system call to flush caches so that loose-objects remain consistent in the face of a unclean system shutdown.

This can speed up operations like git diff and git status especially on filesystems like NFS that have weak caching semantics and thus relatively high IO latencies. When enabled, Git will do the index comparison to the filesystem data in parallel, allowing overlapping IO’s. Defaults to true.

On some file system/operating system combinations, this is unreliable. Set this config setting to rename there; However, This will remove the check that makes sure that existing object files will not get overwritten.

This setting defaults to "refs/notes/commits", and it can be overridden by the GIT_NOTES_REF environment variable. See git-notes(1).

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 git. In particular, this is useful when used with -c to pass in one-time configurations or -p to force pagination. For example, loud-rebase = -c commit.verbose=true rebase can be defined such that running git loud-rebase would be equivalent to git -c commit.verbose=true rebase. Also, ps = -p status would be a helpful alias since git ps would paginate the output of git status where the original command does not.

If the alias expansion is prefixed with an exclamation point, it will be treated as a shell command. For example, defining alias.new = !gitk --all --not ORIG_HEAD, the invocation git new is equivalent to running the shell command gitk --all --not ORIG_HEAD. Note that shell commands will be executed from the top-level directory of a repository, which may not necessarily be the current directory. GIT_PREFIX is set as returned by running git rev-parse --show-prefix from the original current directory. See git-rev-parse(1).

When merges (or just m), pass the --rebase-merges option to git rebase so that the local merge commits are included in the rebase (see git-rebase(1) for details).

When the value is interactive (or just i), the rebase is run in interactive mode.

NOTE: this is a possibly dangerous operation; do not use it unless you understand the implications (see git-rebase(1) for details).

Currently this is used by git-switch(1) and git-checkout(1) when git checkout <something> or git switch <something> will checkout the <something> branch on another remote, and by git-worktree(1) when git worktree add refers to a remote branch. This setting might be used for other checkout-like commands or functionality in the future.

Note: 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.

This setting should be set to a comma-separated list of color and date settings, starting and ending with a color, the dates should be set from oldest to newest. The metadata will be colored with the specified colors if the line was introduced before the given timestamp, overwriting older timestamped colors.

Instead of an absolute timestamp relative timestamps work as well, e.g. 2.weeks.ago is valid to address anything older than 2 weeks.

It defaults to blue,12 month ago,white,1 month ago,red, which colors everything older than one year blue, recent changes between one month and one year old are kept white, and lines introduced within the last month are colored red.

This does not affect git-format-patch(1) or the git-diff-* plumbing commands. Can be overridden on the command line with the --color[=<when>] option.

See the --tool=<tool> option in git-difftool(1) for more details.

See the --trust-exit-code option in git-difftool(1) for more details.

Note that this setting should only be set by git-init(1) or git-clone(1). Trying to change it after initialization will not work and will produce hard-to-diagnose issues.

When enabling extensions.worktreeConfig, you must be careful to move certain values from the common config file to the main working tree’s config.worktree file, if present:

See also the --negotiate-only and --negotiation-tip options to git-fetch(1).

A value of 0 will give some reasonable default. If unset, it defaults to 1.

For submodules, this setting can be overridden using the submodule.fetchJobs config setting.

If one wishes to use the ref ref/notes/true, please use that literal instead.

This configuration can be specified multiple times in order to allow multiple notes refs to be included. In that case, it will behave similarly to multiple --[no-]notes[=] options passed in. That is, a value of true will show the default notes, a value of <ref> will also show notes from that notes ref and a value of false will negate previous configurations and not show notes.

For example,

[format]
        notes = true
        notes = foo
        notes = false
        notes = bar

will only show notes from refs/notes/bar.

Setting fsck.<msg-id> will be picked up by git-fsck(1), but to accept pushes of such data set receive.fsck.<msg-id> instead, or to clone or fetch it set fetch.fsck.<msg-id>.

The rest of the documentation discusses fsck.* for brevity, but the same applies for the corresponding receive.fsck.* and fetch.<msg-id>.*. variables.

Unlike variables like color.ui and core.editor the receive.fsck.<msg-id> and fetch.fsck.<msg-id> variables will not fall back on the fsck.<msg-id> configuration if they aren’t set. To uniformly configure the same fsck settings in different circumstances all three of them they must all set to the same values.

When fsck.<msg-id> is set, errors can be switched to warnings and vice versa by configuring the fsck.<msg-id> setting where the <msg-id> is the fsck message ID and the value is one of error, warn or ignore. For convenience, fsck prefixes the error/warning with the message ID, e.g. "missingEmail: invalid author/committer line - missing email" means that setting fsck.missingEmail = ignore will hide that issue.

In general, it is better to enumerate existing objects with problems with fsck.skipList, instead of listing the kind of breakages these problematic objects share to be ignored, as doing the latter will allow new instances of the same breakages go unnoticed.

Setting an unknown fsck.<msg-id> value will cause fsck to die, but doing the same for receive.fsck.<msg-id> and fetch.fsck.<msg-id> will only cause git to warn.

See Fsck Messages section of git-fsck(1) for supported values of <msg-id>.

This feature is useful when an established project should be accepted despite early commits containing errors that can be safely ignored such as invalid committer email addresses. Note: corrupt objects cannot be skipped with this setting.

Like fsck.<msg-id> this variable has corresponding receive.fsck.skipList and fetch.fsck.skipList variants.

Unlike variables like color.ui and core.editor the receive.fsck.skipList and fetch.fsck.skipList variables will not fall back on the fsck.skipList configuration if they aren’t set. To uniformly configure the same fsck settings in different circumstances all three of them they must all set to the same values.

Older versions of Git (before 2.20) documented that the object names list should be sorted. This was never a requirement, the object names could appear in any order, but when reading the list we tracked whether the list was sorted for the purposes of an internal binary search 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 is used instead, so there’s now no reason to pre-sort the list.

See the documentation for the --depth option in git-repack(1) for more details.

See the documentation for the --window option in git-repack(1) for more details.

Setting this to 0 disables not only automatic packing based on the number of loose objects, but any other heuristic git gc --auto will otherwise use to determine if there’s work to do, such as gc.autoPackLimit.

See the gc.bigPackThreshold configuration variable below. When in use, it’ll affect how the auto pack limit works.

Note that if the number of kept packs is more than gc.autoPackLimit, this configuration variable is ignored, all packs except the base pack will be repacked. After this the number of packs should go below gc.autoPackLimit and gc.bigPackThreshold should be respected again.

If the amount of memory estimated for git repack to run smoothly is not available and gc.bigPackThreshold is not set, the largest pack will also be excluded (this is the equivalent of running git gc with --keep-largest-pack).

These types of entries are generally created as a result of using git commit --amend or git rebase and are the commits prior to the amend or rebase occurring. Since these changes are not part of the current project most users will want to expire them sooner, which is why the default is more aggressive than gc.reflogExpire.

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 fully when the public key is present in the allowedSignersFile. Otherwise the trust level is undefined and git verify-commit/tag will fail.

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.

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.

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’s creation. This allows users to change a signing key without invalidating all previously made signatures.

Using a SSH CA key with the cert-authority option (see ssh-keygen(1) "CERTIFICATES") is also valid.

The first format redirects all requests to the given HOST:PORT to the provided ADDRESS(s). The second format clears all previous config values for that HOST:PORT combination. To allow easy overriding of all the settings inherited from the system config, an empty value will reset all resolution information to the empty list.

Can be overridden by the GIT_SSL_VERSION environment variable. To force git to use libcurl’s default ssl version and ignore any explicit http.sslversion option, set GIT_SSL_VERSION to the empty string.

Can be overridden by the GIT_SSL_CIPHER_LIST environment variable. To force git to use libcurl’s default cipher list and ignore any explicit http.sslCipherList option, set GIT_SSL_CIPHER_LIST to the empty string.

Note that raising this limit is only effective for disabling chunked transfer encoding and therefore should be used only where the remote server or a proxy only supports HTTP/1.0 or is noncompliant with the HTTP standard. Raising this is not, in general, an effective solution for most push problems, but can increase memory consumption significantly since the entire buffer is allocated even for small pushes.

The list above is ordered by decreasing precedence; a URL that matches a config key’s path is preferred to one that matches its user name. For example, if the URL is https://user@example.com/foo/bar a config key match of https://example.com/foo will be preferred over a config key match of https://user@example.com.

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.

If the format is set to "auto:foo" and the pager is in use, format "foo" will be the used for the date format. Otherwise "default" will be used.

An element with an empty value can be used to clear the list of globs accumulated from previous configuration entries. When there is no merge.suppressDest variable defined, the default value of master is used for backward compatibility.

This setting can be overridden by passing the --strategy option to git-notes(1).

This setting can be overridden with the GIT_NOTES_DISPLAY_REF environment variable, which must be a colon separated list of refs or globs.

A warning will be issued for refs that do not exist, but a glob that does not match any refs is silently ignored.

This setting can be disabled by the --no-notes option to the git log family of commands, or by the --notes=<ref> option accepted by those commands.

The effective value of "core.notesRef" (possibly overridden by GIT_NOTES_REF) is also implicitly added to the list of refs to be displayed.

This setting can be overridden with the GIT_NOTES_REWRITE_REF environment variable, which must be a colon separated list of refs or globs.

This setting can be overridden with the GIT_NOTES_REWRITE_MODE environment variable.

Does not have a default value; you must configure this variable to enable note rewriting. Set it to refs/notes/commits to enable rewriting for the default commit notes.

Can be overridden with the GIT_NOTES_REWRITE_REF environment variable. See notes.rewrite.<command> above for a further description of its format.

Note that changing the compression level will not automatically recompress all existing objects. You can force recompression by passing the -F option to git-repack(1).

If you have an old Git that does not understand the version 2 *.idx file, cloning or fetching over a non native protocol (e.g. "http") that will copy both *.pack file and corresponding *.idx file from the other side may give you a repository that cannot be accessed with your older version of Git. If the *.pack file is smaller than 2 GB, however, you can use git-index-pack(1) on the *.pack file to regenerate the *.idx file.

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 split).

The minimum size allowed is limited to 1 MiB. The default is unlimited. Common unit suffixes of k, m, or g are supported.

Note that setting this configuration to refs/foo does not mean that the commits at the tips of refs/foo/bar and refs/foo/baz will necessarily be selected. This is because commits are selected for bitmaps from within a series of windows of variable length.

If a commit at the tip of any reference which is a suffix of any value of this configuration is seen in a window, it is immediately given preference over any other commit in that window.

When writing a multi-pack reachability bitmap, no new namehashes are computed; instead, any namehashes stored in an existing bitmap are permuted into their appropriate location when writing a new bitmap.

The protocol names currently used by git are:

When merges (or just m), pass the --rebase-merges option to git rebase so that the local merge commits are included in the rebase (see git-rebase(1) for details).

When the value is interactive (or just i), the rebase is run in interactive mode.

NOTE: this is a possibly dangerous operation; do not use it unless you understand the implications (see git-rebase(1) for details).

This is a multi-valued variable, and an empty value can be used in a higher priority configuration file (e.g. .git/config in a repository) to clear the values inherited from a lower priority configuration files (e.g. $HOME/.gitconfig).

Example:
/etc/gitconfig
  push.pushoption = a
  push.pushoption = b
~/.gitconfig
  push.pushoption = c
repo/.git/config
  push.pushoption =
  push.pushoption = b
This will result in only b (a and c are cleared).

        p deadbee The oneline of the commit
        p fa1afe1 The oneline of the next commit
        ...

instead of:

        pick deadbee The oneline of the commit
        pick fa1afe1 The oneline of the next commit
        ...

Defaults to false.

Another option is "updateInstead" which will update the working tree if pushing into the current branch. This option is intended for synchronizing working directories when one side is not easily accessible via interactive ssh (e.g. a live web site, hence the requirement 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.

By default, "updateInstead" will refuse the push if the working tree or the index have any difference from the HEAD, but the push-to-checkout hook can be used to customize this. See githooks(5).

For example, if this variable is set to "refs/for", pushing to reference such as "refs/for/master" will not create or update a reference named "refs/for/master", but may create or update a pull request directly by running the hook "proc-receive".

Optional modifiers can be provided in the beginning of the value to filter commands for specific actions: create (a), modify (m), delete (d). A ! can be included in the modifiers to negate the reference prefix entry. E.g.:

git config --system --add receive.procReceiveRefs ad:refs/heads
git config --system --add receive.procReceiveRefs !:refs/heads

See also remote.<name>.prune and the PRUNING section of git-fetch(1).

This is a multi-valued setting, i.e. you can add more than one directory via git config --add. To reset the list of safe directories (e.g. to override any such directories specified in the system config), add a safe.directory entry with an empty value.

This config setting is only respected in protected configuration (see the section called “SCOPES”). This prevents the untrusted repository from tampering with this value.

The value of this setting is interpolated, i.e. ~/<path> expands to a path relative to the home directory and %(prefix)/<path> expands to a path relative to Git’s (runtime) prefix.

To completely opt-out of this security check, set safe.directory to the string *. This will allow all repositories to be treated as if their directory was listed in the safe.directory list. If safe.directory=* 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.

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 root 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 root. This is to make it easy to perform a common sequence during installation "make && sudo make install". A git process running under sudo runs as root but the sudo 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 SUDO_UID variable from root’s environment before invoking git.

What an alias file in each format looks like can be found in the documentation of the email program of the same name. The differences and limitations from the standard formats are described below:

The default is false, which allows Git to automatically recover from the list of files in the index and working tree falling out of sync.

Set this to true 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.

Regardless of this setting, Git does not check for present-despite-skipped files unless sparse checkout is enabled, so this config option has no effect unless core.sparseCheckout is true.

The config variable ssh.variant can be set to override this detection. Valid values are ssh (to use OpenSSH options), plink, putty, tortoiseplink, simple (no options except the host and remote command). The default auto-detection can be explicitly requested using the value auto. Any other value is treated as ssh. This setting can also be overridden via the environment variable GIT_SSH_VARIANT.

The current command-line parameters used for each variant are as follows:

Except for the simple variant, command-line parameters are likely to change as git gains new features.

If this variable is not specified, it defaults to normal. This variable can be overridden with the -u|--untracked-files option of git-status(1) and git-commit(1).

When set to true, it can be deactivated via the --no-recurse-submodules option. Note that some Git commands lacking this option may call some of the above commands affected by submodule.recurse; for instance git remote update will call git fetch but does not have a --no-recurse-submodules option. For these commands a workaround is to temporarily change the configuration value by using git -c submodule.recurse=0.

The following list shows the commands that accept --recurse-submodules and whether they are supported by this setting.

Note that this is currently limited to detecting credentials in remote.<name>.url configuration, it won’t detect credentials in remote.<name>.pushurl configuration.

You might want to enable this to prevent inadvertent credentials exposure, e.g. because:

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 fsck.<msg-id>), and potential security issues like the existence of a .GIT directory or a malicious .gitmodules file (see the release notes for v2.2.1 and v2.17.1 for details). Other sanity and security checks may be added in future releases.

On the receiving side, failing fsckObjects will make those objects unreachable, see "QUARANTINE ENVIRONMENT" in git-receive-pack(1). On the fetch side, malformed objects will instead be left unreferenced in the repository.

Due to the non-quarantine nature of the fetch.fsckObjects implementation it cannot be relied upon to leave the object store clean like receive.fsckObjects can.

As objects are unpacked they’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.

For now, the paranoid need to find some way to emulate the quarantine environment if they’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).

You may also include a ! in front of the ref name to negate the entry, explicitly exposing it, even if an earlier entry marked it as hidden. If you have multiple hideRefs values, later entries override earlier ones (and entries in more-specific config files override less-specific ones).

If a namespace is in use, the namespace prefix is stripped from each reference before it is matched against transfer.hiderefs patterns. In order to match refs before stripping, add a ^ in front of the ref name. If you combine ! and ^, ! must be specified first.

For example, if refs/heads/master is specified in transfer.hideRefs and the current namespace is foo, then refs/namespaces/foo/refs/heads/master is omitted from the advertisements. If uploadpack.allowRefInWant is set, upload-pack will treat want-ref refs/heads/master in a protocol v2 fetch command as if refs/namespaces/foo/refs/heads/master did not exist. receive-pack, on the other hand, will still advertise the object id the ref is pointing to without mentioning its name (a so-called ".have" line).

Even if you hide refs, a client may still be able to steal the target objects via the techniques described in the "SECURITY" section of the gitnamespaces(7) man page; it’s best to keep private data in a separate repository.

Note that this configuration variable is only respected when it is specified in protected configuration (see the section called “SCOPES”). This is a safety measure against fetching from untrusted repositories.

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 protocol.*.allow config to permit the request. In particular, protocols you expect to use for submodules must be set to always rather than the default of user. See the description of protocol.allow above.

Note that the name forms of these variables conventionally refer to some form of a personal name. See git-commit(1) and the environment variables section of git(1) for more information on these settings and the credential.username option if you’re looking for authentication credentials instead.

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".

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.
