git(1) Manual Page
git - the stupid content tracker
git [--version] [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path] [-p|--paginate|--no-pager] [--no-replace-objects] [--bare] [--git-dir=<path>] [--work-tree=<path>] [-c <name>=<value>] [--help] <command> [<args>]
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 Everyday Git for a useful minimum set of commands, and "man git-commandname" for documentation of each command. CVS users may also want to read gitcvs-migration(7). See the Git User's Manual for a more in-depth introduction.
The <command> is either a name of a Git command (see below) or an alias as defined in the configuration file (see git-config(1)).
Formatted and hyperlinked version of the latest git documentation can be viewed at http://www.kernel.org/pub/software/scm/git/docs/.
Prints the git suite version that the git program came from.
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 <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).
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.
Print the path, without trailing slash, where git's HTML documentation is installed and exit.
Print the manpath (see man(1)) for the man pages for this version of git and exit.
Print the path where the Info files documenting this version of git are installed and exit.
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).
Do not pipe git output into a pager.
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.
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).
Treat the repository as a bare repository. If GIT_DIR environment is not set, it is set to the current working directory.
Do not use replacement refs to replace git objects. See git-replace(1) for more information.
See the references above to get started using git. The following is probably more detail than necessary for a first-time user.
See gitworkflows(7) for an overview of recommended workflows.
See also the howto documents for some useful examples.
The internals are documented in the GIT API documentation.
We divide git into high level ("porcelain") commands and low level ("plumbing") commands.
High-level commands (porcelain)
We separate the porcelain commands into the main commands and some ancillary user utilities.
Main porcelain commands
Interacting with Others
These commands are to interact with foreign SCM and with other people via patch over e-mail.
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.
In general, the interrogate commands do not touch the files in the working tree.
The following are helper commands used by the above; end users typically do not use them directly.
Internal helper commands
These are internal helper commands used by other commands; end users typically do not use them directly.
Starting from 0.99.9 (actually mid 0.99.8.GIT), .git/config file is used to hold per-repository configuration options. It is a simple text file modeled after .ini format familiar to some people. Here is an example:
# # A '#' or ';' character indicates a comment. # ; core variables [core] ; Don't trust file modes filemode = false ; user identity [user] name = "Junio C Hamano" email = "email@example.com"
Various commands read from the configuration file and adjust their operation accordingly. See git-config(1) for a list.
Indicates the object name for any type of object.
Indicates a blob object name.
Indicates a tree object name.
Indicates a commit object name.
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>.
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>.
Indicates that an object type is required. Currently one of: blob, tree, commit, or tag.
Indicates a filename - almost always relative to the root of the tree structure GIT_INDEX_FILE describes.
Any git command accepting any <object> can also use the following symbolic notation:
indicates the head of the current branch (i.e. the contents of $GIT_DIR/HEAD).
a valid tag name (i.e. the contents of $GIT_DIR/refs/tags/<tag>).
a valid head name (i.e. the contents of $GIT_DIR/refs/heads/<head>).
For a more complete list of ways to spell object names, see "SPECIFYING REVISIONS" section in gitrevisions(7).
Please see gitglossary(7).
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 Cogito etc.
This environment allows the specification of an alternate index file. If not specified, the default of $GIT_DIR/index is used.
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.
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.
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.
Set the path to the working tree. The value will not be used in combination with repositories found automatically in a .git directory (i.e. $GIT_DIR is not set). This can also be controlled by the --work-tree command line option and the core.worktree configuration variable.
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. It will not exclude the current working directory or a GIT_DIR set on the command line or in the environment. (Useful for excluding slow-loading network directories.)
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.
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.
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
<old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the contents of <old|new>, <old|new>-hex:: are the 40-hexdigit SHA1 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>.
A number controlling the amount of output shown by the recursive merge strategy. Overrides merge.verbosity. See git-merge(1)
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).
If this environment variable is set then git fetch and git push will use this command instead of ssh when they need to connect to a remote system. The $GIT_SSH command will be given exactly two arguments: the username@host (or just host) from the URL and the shell command to execute on that remote system.
To pass options to the program that you want to list in GIT_SSH you will need to wrap the program and options into a shell script, then set GIT_SSH to refer to the shell script.
Usually it is easier to configure any desired options through your personal .ssh/config file. Please consult your ssh documentation for further details.
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).
If this environment variable is set to "1", then commands such as git blame (in incremental mode), git rev-list, git log, and git whatchanged will force a flush of the output stream after each commit-oriented 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.
If this variable is set to "1", "2" or "true" (comparison is case insensitive), git will print trace: messages on stderr telling about alias expansion, built-in command execution and external command execution. If this variable is set to an integer value greater than 1 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 this 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.
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 SHA1 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 SHA1 name of an object or the name of another ref. Refs with names beginning ref/head/ contain the SHA1 name of the most recent commit (or "head") of a branch under development. SHA1 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.
Git was started by Linus Torvalds, and is currently maintained by Junio C Hamano. Numerous contributions have come from the git mailing list <firstname.lastname@example.org>. For a more complete list of contributors, see http://git-scm.com/about. If you have a clone of git.git itself, the output of git-shortlog(1) and git-blame(1) can show you the authors for specific parts of the project.
Report bugs to the Git mailing list <email@example.com> where the development and maintenance is primarily done. You do not have to be subscribed to the list to send a message there.
