GIT(1)                                      Git Manual                                     GIT(1)

NAME
       git - the stupid content tracker

SYNOPSIS
       git [--version] [--help] [-C <path>] [-c <name>=<value>]
           [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
           [-p|--paginate|--no-pager] [--no-replace-objects] [--bare]
           [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
           [--super-prefix=<path>]
           <command> [<args>]

DESCRIPTION
       Git is a fast, scalable, distributed revision control system with an unusually rich
       command set that provides both high-level operations and full access to internals.

       See gittutorial(7) to get started, then see giteveryday(7) for a useful minimum set of
       commands. The Git User’s Manual[1] has a more in-depth introduction.

       After you mastered the basic concepts, you can come back to this page to learn what
       commands Git offers. You can learn more about individual Git commands with "git help
       command". gitcli(7) manual page gives you an overview of the command-line command syntax.

       A formatted and hyperlinked copy of the latest Git documentation can be viewed at
       https://git.github.io/htmldocs/git.html.

OPTIONS
       --version
           Prints the Git suite version that the git program came from.

       --help
           Prints the synopsis and a list of the most commonly used commands. If the option --all
           or -a is given then all available commands are printed. If a Git command is named this
           option will bring up the manual page for that command.

           Other options are available to control how the manual page is displayed. See git-
           help(1) for more information, because git --help ...  is converted internally into git
           help ....

       -C <path>
           Run as if git was started in <path> instead of the current working directory. When
           multiple -C options are given, each subsequent non-absolute -C <path> is interpreted
           relative to the preceding -C <path>.

           This option affects options that expect path name like --git-dir and --work-tree in
           that their interpretations of the path names would be made relative to the working
           directory caused by the -C option. For example the following invocations are
           equivalent:

               git --git-dir=a.git --work-tree=b -C c status
               git --git-dir=c/a.git --work-tree=c/b status

       -c <name>=<value>
           Pass a configuration parameter to the command. The value given will override values
           from configuration files. The <name> is expected in the same format as listed by git
           config (subkeys separated by dots).

           Note that omitting the = in git -c foo.bar ...  is allowed and sets foo.bar to the
           boolean true value (just like [foo]bar would in a config file). Including the equals
           but with an empty value (like git -c foo.bar= ...) sets foo.bar to the empty string.

       --exec-path[=<path>]
           Path to wherever your core Git programs are installed. This can also be controlled by
           setting the GIT_EXEC_PATH environment variable. If no path is given, git will print
           the current setting and then exit.

       --html-path
           Print the path, without trailing slash, where Git’s HTML documentation is installed
           and exit.

       --man-path
           Print the manpath (see man(1)) for the man pages for this version of Git and exit.

       --info-path
           Print the path where the Info files documenting this version of Git are installed and
           exit.

       -p, --paginate
           Pipe all output into less (or if set, $PAGER) if standard output is a terminal. This
           overrides the pager.<cmd> configuration options (see the "Configuration Mechanism"
           section below).

       --no-pager
           Do not pipe Git output into a pager.

       --git-dir=<path>
           Set the path to the repository. This can also be controlled by setting the GIT_DIR
           environment variable. It can be an absolute path or relative path to current working
           directory.

       --work-tree=<path>
           Set the path to the working tree. It can be an absolute path or a path relative to the
           current working directory. This can also be controlled by setting the GIT_WORK_TREE
           environment variable and the core.worktree configuration variable (see core.worktree
           in git-config(1) for a more detailed discussion).

       --namespace=<path>
           Set the Git namespace. See gitnamespaces(7) for more details. Equivalent to setting
           the GIT_NAMESPACE environment variable.

       --super-prefix=<path>
           Currently for internal use only. Set a prefix which gives a path from above a
           repository down to its root. One use is to give submodules context about the
           superproject that invoked it.

       --bare
           Treat the repository as a bare repository. If GIT_DIR environment is not set, it is
           set to the current working directory.

       --no-replace-objects
           Do not use replacement refs to replace Git objects. See git-replace(1) for more
           information.

       --literal-pathspecs
           Treat pathspecs literally (i.e. no globbing, no pathspec magic). This is equivalent to
           setting the GIT_LITERAL_PATHSPECS environment variable to 1.

       --glob-pathspecs
           Add "glob" magic to all pathspec. This is equivalent to setting the GIT_GLOB_PATHSPECS
           environment variable to 1. Disabling globbing on individual pathspecs can be done
           using pathspec magic ":(literal)"

       --noglob-pathspecs
           Add "literal" magic to all pathspec. This is equivalent to setting the
           GIT_NOGLOB_PATHSPECS environment variable to 1. Enabling globbing on individual
           pathspecs can be done using pathspec magic ":(glob)"

       --icase-pathspecs
           Add "icase" magic to all pathspec. This is equivalent to setting the
           GIT_ICASE_PATHSPECS environment variable to 1.

LOW-LEVEL COMMANDS (PLUMBING)
       Although Git includes its own porcelain layer, its low-level commands are sufficient to
       support development of alternative porcelains. Developers of such porcelains might start
       by reading about git-update-index(1) and git-read-tree(1).

       The interface (input, output, set of options and the semantics) to these low-level
       commands are meant to be a lot more stable than Porcelain level commands, because these
       commands are primarily for scripted use. The interface to Porcelain commands on the other
       hand are subject to change in order to improve the end user experience.

       The following description divides the low-level commands into commands that manipulate
       objects (in the repository, index, and working tree), commands that interrogate and
       compare objects, and commands that move objects and references between repositories.

CONFIGURATION MECHANISM
       Git uses a simple text format to store customizations that are per repository and are per
       user. Such a configuration file may look like this:

           #
           # A '#' or ';' character indicates a comment.
           #

           ; core variables
           [core]
                   ; Don't trust file modes

       Various commands read from the configuration file and adjust their operation accordingly.
       See git-config(1) for a list and more details about the configuration mechanism.

IDENTIFIER TERMINOLOGY
       <object>
           Indicates the object name for any type of object.

       <blob>
           Indicates a blob object name.

       <tree>
           Indicates a tree object name.

       <commit>
           Indicates a commit object name.

       <tree-ish>
           Indicates a tree, commit or tag object name. A command that takes a <tree-ish>
           argument ultimately wants to operate on a <tree> object but automatically dereferences
           <commit> and <tag> objects that point at a <tree>.

       <commit-ish>
           Indicates a commit or tag object name. A command that takes a <commit-ish> argument
           ultimately wants to operate on a <commit> object but automatically dereferences <tag>
           objects that point at a <commit>.

       <type>
           Indicates that an object type is required. Currently one of: blob, tree, commit, or
           tag.

       <file>
           Indicates a filename - almost always relative to the root of the tree structure
           GIT_INDEX_FILE describes.

SYMBOLIC IDENTIFIERS
       Any Git command accepting any <object> can also use the following symbolic notation:

       HEAD
           indicates the head of the current branch.

       <tag>
           a valid tag name (i.e. a refs/tags/<tag> reference).

       <head>
           a valid head name (i.e. a refs/heads/<head> reference).

       For a more complete list of ways to spell object names, see "SPECIFYING REVISIONS" section
       in gitrevisions(7).

FILE/DIRECTORY STRUCTURE
       Please see the gitrepository-layout(5) document.

       Read githooks(5) for more details about each hook.

       Higher level SCMs may provide and manage additional information in the $GIT_DIR.

TERMINOLOGY
       Please see gitglossary(7).

ENVIRONMENT VARIABLES
       Various Git commands use the following environment variables:

   The Git Repository
       These environment variables apply to all core Git commands. Nb: it is worth noting that
       they may be used/overridden by SCMS sitting above Git so take care if using a foreign
       front-end.

       GIT_INDEX_FILE
           This environment allows the specification of an alternate index file. If not
           specified, the default of $GIT_DIR/index is used.

       GIT_INDEX_VERSION
           This environment variable allows the specification of an index version for new
           repositories. It won’t affect existing index files. By default index file version 2 or
           3 is used. See git-update-index(1) for more information.

       GIT_OBJECT_DIRECTORY
           If the object storage directory is specified via this environment variable then the
           sha1 directories are created underneath - otherwise the default $GIT_DIR/objects
           directory is used.

       GIT_ALTERNATE_OBJECT_DIRECTORIES
           Due to the immutable nature of Git objects, old objects can be archived into shared,
           read-only directories. This variable specifies a ":" separated (on Windows ";"
           separated) list of Git object directories which can be used to search for Git objects.
           New objects will not be written to these directories.

       GIT_DIR
           If the GIT_DIR environment variable is set then it specifies a path to use instead of
           the default .git for the base of the repository. The --git-dir command-line option
           also sets this value.

       GIT_WORK_TREE
           Set the path to the root of the working tree. This can also be controlled by the
           --work-tree command-line option and the core.worktree configuration variable.

       GIT_NAMESPACE
           Set the Git namespace; see gitnamespaces(7) for details. The --namespace command-line
           option also sets this value.

       GIT_CEILING_DIRECTORIES
           This should be a colon-separated list of absolute paths. If set, it is a list of
           directories that Git should not chdir up into while looking for a repository directory
           (useful for excluding slow-loading network directories). It will not exclude the
           current working directory or a GIT_DIR set on the command line or in the environment.
           Normally, Git has to read the entries in this list and resolve any symlink that might
           be present in order to compare them with the current directory. However, if even this
           access is slow, you can add an empty entry to the list to tell Git that the subsequent
           entries are not symlinks and needn’t be resolved; e.g.,
           GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink.

       GIT_DISCOVERY_ACROSS_FILESYSTEM
           When run in a directory that does not have ".git" repository directory, Git tries to
           find such a directory in the parent directories to find the top of the working tree,
           but by default it does not cross filesystem boundaries. This environment variable can
           be set to true to tell Git not to stop at filesystem boundaries. Like
           GIT_CEILING_DIRECTORIES, this will not affect an explicit repository directory set via
           GIT_DIR or on the command line.

       GIT_COMMON_DIR
           If this variable is set to a path, non-worktree files that are normally in $GIT_DIR
           will be taken from this path instead. Worktree-specific files such as HEAD or index
           are taken from $GIT_DIR. See gitrepository-layout(5) and git-worktree(1) for details.
           This variable has lower precedence than other path variables such as GIT_INDEX_FILE,
           GIT_OBJECT_DIRECTORY...

   Git Commits
       GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL, GIT_AUTHOR_DATE, GIT_COMMITTER_NAME,
       GIT_COMMITTER_EMAIL, GIT_COMMITTER_DATE, EMAIL
           see git-commit-tree(1)

   Git Diffs
       GIT_DIFF_OPTS
           Only valid setting is "--unified=??" or "-u??" to set the number of context lines
           shown when a unified diff is created. This takes precedence over any "-U" or
           "--unified" option value passed on the Git diff command line.

       GIT_EXTERNAL_DIFF
           When the environment variable GIT_EXTERNAL_DIFF is set, the program named by it is
           called, instead of the diff invocation described above. For a path that is added,
           removed, or modified, GIT_EXTERNAL_DIFF is called with 7 parameters:

               path old-file old-hex old-mode new-file new-hex new-mode

           where:

       <old|new>-file
           are files GIT_EXTERNAL_DIFF can use to read the contents of <old|new>,

       <old|new>-hex
           are the 40-hexdigit SHA-1 hashes,

       <old|new>-mode
           are the octal representation of the file modes.

           The file parameters can point at the user’s working file (e.g.  new-file in
           "git-diff-files"), /dev/null (e.g.  old-file when a new file is added), or a temporary
           file (e.g.  old-file in the index).  GIT_EXTERNAL_DIFF should not worry about
           unlinking the temporary file --- it is removed when GIT_EXTERNAL_DIFF exits.

           For a path that is unmerged, GIT_EXTERNAL_DIFF is called with 1 parameter, <path>.

           For each path GIT_EXTERNAL_DIFF is called, two environment variables,
           GIT_DIFF_PATH_COUNTER and GIT_DIFF_PATH_TOTAL are set.

       GIT_DIFF_PATH_COUNTER
           A 1-based counter incremented by one for every path.

       GIT_DIFF_PATH_TOTAL
           The total number of paths.

   other
       GIT_MERGE_VERBOSITY
           A number controlling the amount of output shown by the recursive merge strategy.
           Overrides merge.verbosity. See git-merge(1)

       GIT_PAGER
           This environment variable overrides $PAGER. If it is set to an empty string or to the
           value "cat", Git will not launch a pager. See also the core.pager option in git-
           config(1).

       GIT_EDITOR
           This environment variable overrides $EDITOR and $VISUAL. It is used by several Git
           commands when, on interactive mode, an editor is to be launched. See also git-var(1)
           and the core.editor option in git-config(1).

       GIT_SSH, GIT_SSH_COMMAND
           If either of these environment variables is set then git fetch and git push will use
           the specified command instead of ssh when they need to connect to a remote system. The
           command will be given exactly two or four arguments: the username@host (or just host)
           from the URL and the shell command to execute on that remote system, optionally
           preceded by -p (literally) and the port from the URL when it specifies something other
           than the default SSH port.

           $GIT_SSH_COMMAND takes precedence over $GIT_SSH, and is interpreted by the shell,
           which allows additional arguments to be included.  $GIT_SSH on the other hand must be
           just the path to a program (which can be a wrapper shell script, if additional
           arguments are needed).

           Usually it is easier to configure any desired options through your personal
           .ssh/config file. Please consult your ssh documentation for further details.

       GIT_ASKPASS
           If this environment variable is set, then Git commands which need to acquire passwords
           or passphrases (e.g. for HTTP or IMAP authentication) will call this program with a
           suitable prompt as command-line argument and read the password from its STDOUT. See
           also the core.askPass option in git-config(1).

       GIT_TERMINAL_PROMPT
           If this environment variable is set to 0, git will not prompt on the terminal (e.g.,
           when asking for HTTP authentication).

       GIT_CONFIG_NOSYSTEM
           Whether to skip reading settings from the system-wide $(prefix)/etc/gitconfig file.
           This environment variable can be used along with $HOME and $XDG_CONFIG_HOME to create
           a predictable environment for a picky script, or you can set it temporarily to avoid
           using a buggy /etc/gitconfig file while waiting for someone with sufficient
           permissions to fix it.

       GIT_FLUSH
           If this environment variable is set to "1", then commands such as git blame (in
           incremental mode), git rev-list, git log, git check-attr and git check-ignore will
           force a flush of the output stream after each record have been flushed. If this
           variable is set to "0", the output of these commands will be done using completely
           buffered I/O. If this environment variable is not set, Git will choose buffered or
           record-oriented flushing based on whether stdout appears to be redirected to a file or
           not.

       GIT_TRACE
           Enables general trace messages, e.g. alias expansion, built-in command execution and
           external command execution.

           If this variable is set to "1", "2" or "true" (comparison is case insensitive), trace
           messages will be printed to stderr.

           If the variable is set to an integer value greater than 2 and lower than 10 (strictly)
           then Git will interpret this value as an open file descriptor and will try to write
           the trace messages into this file descriptor.

           Alternatively, if the variable is set to an absolute path (starting with a /
           character), Git will interpret this as a file path and will try to write the trace
           messages into it.

           Unsetting the variable, or setting it to empty, "0" or "false" (case insensitive)
           disables trace messages.

       GIT_TRACE_PACK_ACCESS
           Enables trace messages for all accesses to any packs. For each access, the pack file
           name and an offset in the pack is recorded. This may be helpful for troubleshooting
           some pack-related performance problems. See GIT_TRACE for available trace output
           options.

       GIT_TRACE_PACKET
           Enables trace messages for all packets coming in or out of a given program. This can
           help with debugging object negotiation or other protocol issues. Tracing is turned off
           at a packet starting with "PACK" (but see GIT_TRACE_PACKFILE below). See GIT_TRACE for
           available trace output options.

       GIT_TRACE_PACKFILE
           Enables tracing of packfiles sent or received by a given program. Unlike other trace
           output, this trace is verbatim: no headers, and no quoting of binary data. You almost
           certainly want to direct into a file (e.g., GIT_TRACE_PACKFILE=/tmp/my.pack) rather
           than displaying it on the terminal or mixing it with other trace output.

           Note that this is currently only implemented for the client side of clones and
           fetches.

       GIT_TRACE_PERFORMANCE
           Enables performance related trace messages, e.g. total execution time of each Git
           command. See GIT_TRACE for available trace output options.

       GIT_TRACE_SETUP
           Enables trace messages printing the .git, working tree and current working directory
           after Git has completed its setup phase. See GIT_TRACE for available trace output
           options.

       GIT_TRACE_SHALLOW
           Enables trace messages that can help debugging fetching / cloning of shallow
           repositories. See GIT_TRACE for available trace output options.

       GIT_TRACE_CURL
           Enables a curl full trace dump of all incoming and outgoing data, including
           descriptive information, of the git transport protocol. This is similar to doing curl
           --trace-ascii on the command line. This option overrides setting the GIT_CURL_VERBOSE
           environment variable. See GIT_TRACE for available trace output options.

       GIT_LITERAL_PATHSPECS
           Setting this variable to 1 will cause Git to treat all pathspecs literally, rather
           than as glob patterns. For example, running GIT_LITERAL_PATHSPECS=1 git log -- '*.c'
           will search for commits that touch the path *.c, not any paths that the glob *.c
           matches. You might want this if you are feeding literal paths to Git (e.g., paths
           previously given to you by git ls-tree, --raw diff output, etc).

       GIT_GLOB_PATHSPECS
           Setting this variable to 1 will cause Git to treat all pathspecs as glob patterns (aka
           "glob" magic).

       GIT_NOGLOB_PATHSPECS
           Setting this variable to 1 will cause Git to treat all pathspecs as literal (aka
           "literal" magic).

       GIT_ICASE_PATHSPECS
           Setting this variable to 1 will cause Git to treat all pathspecs as case-insensitive.

       GIT_REFLOG_ACTION
           When a ref is updated, reflog entries are created to keep track of the reason why the
           ref was updated (which is typically the name of the high-level command that updated
           the ref), in addition to the old and new values of the ref. A scripted Porcelain
           command can use set_reflog_action helper function in git-sh-setup to set its name to
           this variable when it is invoked as the top level command by the end user, to be
           recorded in the body of the reflog.

       GIT_REF_PARANOIA
           If set to 1, include broken or badly named refs when iterating over lists of refs. In
           a normal, non-corrupted repository, this does nothing. However, enabling it may help
           git to detect and abort some operations in the presence of broken refs. Git sets this
           variable automatically when performing destructive operations like git-prune(1). You
           should not need to set it yourself unless you want to be paranoid about making sure an
           operation has touched every ref (e.g., because you are cloning a repository to make a
           backup).

       GIT_ALLOW_PROTOCOL
           If set, provide a colon-separated list of protocols which are allowed to be used with
           fetch/push/clone. This is useful to restrict recursive submodule initialization from
           an untrusted repository. Any protocol not mentioned will be disallowed (i.e., this is
           a whitelist, not a blacklist). If the variable is not set at all, all protocols are
           enabled. The protocol names currently used by git are:

           ·   file: any local file-based path (including file:// URLs, or local paths)

           ·   git: the anonymous git protocol over a direct TCP connection (or proxy, if
               configured)

           ·   ssh: git over ssh (including host:path syntax, ssh://, etc).

           ·   http: git over http, both "smart http" and "dumb http". Note that this does not
               include https; if you want both, you should specify both as http:https.

           ·   any external helpers are named by their protocol (e.g., use hg to allow the
               git-remote-hg helper)

DISCUSSION
       More detail on the following is available from the Git concepts chapter of the
       user-manual[2] and gitcore-tutorial(7).

       A Git project normally consists of a working directory with a ".git" subdirectory at the
       top level. The .git directory contains, among other things, a compressed object database
       representing the complete history of the project, an "index" file which links that history
       to the current contents of the working tree, and named pointers into that history such as
       tags and branch heads.

       The object database contains objects of three main types: blobs, which hold file data;
       trees, which point to blobs and other trees to build up directory hierarchies; and
       commits, which each reference a single tree and some number of parent commits.

       The commit, equivalent to what other systems call a "changeset" or "version", represents a
       step in the project’s history, and each parent represents an immediately preceding step.
       Commits with more than one parent represent merges of independent lines of development.

       All objects are named by the SHA-1 hash of their contents, normally written as a string of
       40 hex digits. Such names are globally unique. The entire history leading up to a commit
       can be vouched for by signing just that commit. A fourth object type, the tag, is provided
       for this purpose.

       When first created, objects are stored in individual files, but for efficiency may later
       be compressed together into "pack files".

       Named pointers called refs mark interesting points in history. A ref may contain the SHA-1
       name of an object or the name of another ref. Refs with names beginning ref/head/ contain
       the SHA-1 name of the most recent commit (or "head") of a branch under development. SHA-1
       names of tags of interest are stored under ref/tags/. A special ref named HEAD contains
       the name of the currently checked-out branch.

       The index file is initialized with a list of all paths and, for each path, a blob object
       and a set of attributes. The blob object represents the contents of the file as of the
       head of the current branch. The attributes (last modified time, size, etc.) are taken from
       the corresponding file in the working tree. Subsequent changes to the working tree can be
       found by comparing these attributes. The index may be updated with new content, and new
       commits may be created from the content stored in the index.

       The index is also capable of storing multiple entries (called "stages") for a given
       pathname. These stages are used to hold the various unmerged version of a file when a
       merge is in progress.
