The link:user-manual.html[Git User's Manual] has a more 27in-depth introduction. 28 29After you mastered the basic concepts, you can come back to this 30page to learn what commands Git offers. You can learn more about 31individual Git commands with "git help command". linkgit:gitcli[7] 32manual page gives you an overview of the command-line command syntax. 33 34Formatted and hyperlinked version of the latest Git documentation 35can be viewed at `http://git-htmldocs.googlecode.com/git/git.html`. 36 37ifdef::stalenotes[] 38[NOTE] 39============ 40 41You are reading the documentation

Git suite version that the 'git' program came from. 427 428--help:: 429 Prints the synopsis and a list of the most commonly used 430 commands. If the option '--all' or '-a' is given then all 431 available commands are printed. If a Git command is named this 432 option will bring up the manual page for that command. 433+ 434Other options are available to control how the manual page is 435displayed. See linkgit:git-help[1] for more information, 436because `git --help ...` is converted internally into `git 437help ...`. 438 439-C <path>:: 440 Run as if git was started in '<path>' instead of the current working 441 directory. When multiple `-C` options are given, each subsequent 442 non-absolute `-C <path>` is interpreted relative to the preceding `-C 443 <path>`. 444+ 445This option affects options that expect path name like `--git-dir` and 446`--work-tree` in that their interpretations of the path names would be 447made relative to the working directory caused by the `-C` option. For 448example the following invocations are equivalent: 449 450 git --git-dir=a.git --work-tree=b -C c status 451 git --git-dir=c/a.git --work-tree=c/b status 452 453-c <name>=<value>:: 454 Pass a configuration parameter to the command. The value 455 given will override values from configuration files. 456 The <name> is expected in the same format as listed by 457 'git config' (subkeys separated by dots). 458+ 459Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets 460`foo.bar` to the boolean true value (just like `[foo]bar` would in a 461config file). Including the equals but with an empty value (like `git -c 462foo.bar= ...`) sets `foo.bar` to the empty string. 463 464--exec-path[=<path>]:: 465 Path to wherever your core Git programs are installed. 466 This can also be controlled by setting the GIT_EXEC_PATH 467 environment variable. If no path is given, 'git' will print 468 the current setting and then exit. 469 470--html-path:: 471 Print the path, without trailing slash, where Git's HTML 472 documentation is installed and exit. 473 474--man-path:: 475 Print the manpath (see `man(1)`) for the man pages for 476 this version of Git and exit. 477 478--info-path:: 479 Print the path where the Info files documenting this 480 version of Git are installed and exit. 481 482-p:: 483--paginate:: 484 Pipe all output into 'less' (or if set, $PAGER) if standard 485 output is a terminal. This overrides the `pager.<cmd>` 486 configuration options (see the "Configuration Mechanism" section 487 below). 488 489--no-pager:: 490 Do not pipe Git output into a pager. 491 492--git-dir=<path>:: 493 Set the path to the repository. This can also be controlled by 494 setting the GIT_DIR environment variable. It can be an absolute 495 path or relative path to current working directory. 496 497--work-tree=<path>:: 498 Set the path to the working tree. It can be an absolute path 499 or a path relative to the current working directory. 500 This can also be controlled by setting the GIT_WORK_TREE 501 environment variable and the core.worktree configuration 502 variable (see core.worktree in linkgit:git-config[1] for a 503 more detailed discussion). 504 505--namespace=<path>:: 506 Set the Git namespace. See linkgit:gitnamespaces[7] for more 507 details. Equivalent to setting the `GIT_NAMESPACE` environment 508 variable. 509 510--bare:: 511 Treat the repository as a bare repository. If GIT_DIR 512 environment is not set, it is set to the current working 513 directory. 514 515--no-replace-objects:: 516 Do not use replacement refs to replace Git objects. See 517 linkgit:git-replace[1] for more information. 518 519--literal-pathspecs:: 520 Treat pathspecs literally (i.e. no globbing, no pathspec magic). 521 This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment 522 variable to `1`. 523 524--glob-pathspecs:: 525 Add "glob" magic to all pathspec. This is equivalent to setting 526 the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling 527 globbing on individual pathspecs can be done using pathspec 528 magic ":(literal)" 529 530--noglob-pathspecs:: 531 Add "literal" magic to all pathspec. This is equivalent to setting 532 the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling 533 globbing on individual pathspecs can be done using pathspec 534 magic ":(glob)" 535 536--icase-pathspecs:: 537 Add "icase" magic to all pathspec. This is equivalent to setting 538 the `GIT_ICASE_PATHSPECS` environment variable to `1`. 539 540GIT COMMANDS 541------------ 542 543We divide Git into high level ("porcelain") commands and low level 544("plumbing") commands. 545 546High-level commands (porcelain) 547------------------------------- 548 549We separate the porcelain commands into the main commands and some 550ancillary user utilities. 551 552Main porcelain commands 553~~~~~~~~~~~~~~~~~~~~~~~ 554 555include::cmds-mainporcelain.txt[] 556 557Ancillary Commands 558~~~~~~~~~~~~~~~~~~ 559Manipulators: 560 561include::cmds-ancillarymanipulators.txt[] 562 563Interrogators: 564 565include::cmds-ancillaryinterrogators.txt[] 566 567 568Interacting with Others 569~~~~~~~~~~~~~~~~~~~~~~~ 570 571These commands are to interact with foreign SCM and with other 572people via patch over e-mail. 573 574include::cmds-foreignscminterface.txt[] 575 576 577Low-level commands (plumbing) 578----------------------------- 579 580Although Git includes its 581own porcelain layer, its low-level commands are sufficient to support 582development of alternative porcelains. Developers of such porcelains 583might start by reading about linkgit:git-update-index[1] and 584linkgit:git-read-tree[1]. 585 586The interface (input, output, set of options and the semantics) 587to these low-level commands are meant to be a lot more stable 588than Porcelain level commands, because these commands are 589primarily for scripted use. The interface to Porcelain commands 590on the other hand are subject to change in order to improve the 591end user experience. 592 593The following description divides 594the low-level commands into commands that manipulate objects (in 595the repository, index, and working tree), commands that interrogate and 596compare objects, and commands that move objects and references between 597repositories. 598 599 600Manipulation commands 601~~~~~~~~~~~~~~~~~~~~~ 602 603include::cmds-plumbingmanipulators.txt[] 604 605 606Interrogation commands 607~~~~~~~~~~~~~~~~~~~~~~ 608 609include::cmds-plumbinginterrogators.txt[] 610 611In general, the interrogate commands do not touch the files in 612the working tree. 613 614 615Synching repositories 616~~~~~~~~~~~~~~~~~~~~~ 617 618include::cmds-synchingrepositories.txt[] 619 620The following are helper commands used by the above; end users 621typically do not use them directly. 622 623include::cmds-synchelpers.txt[] 624 625 626Internal helper commands 627~~~~~~~~~~~~~~~~~~~~~~~~ 628 629These are internal helper commands used by other commands; end 630users typically do not use them directly. 631 632include::cmds-purehelpers.txt[] 633 634 635Configuration Mechanism 636----------------------- 637 638Git uses a simple text format to store customizations that are per 639repository and are per user. Such a configuration file may look 640like this: 641 642------------ 643# 644# A '#' or ';' character indicates a comment. 645# 646 647; core variables 648[core] 649 ; Don't trust file modes 650 filemode = false 651 652; user identity 653[user] 654 name = "Junio C Hamano" 655 email = "gitster@pobox.com" 656 657------------ 658 659Various commands read from the configuration file and adjust 660their operation accordingly. See linkgit:git-config[1] for a 661list and more details about the configuration mechanism. 662 663 664Identifier Terminology 665---------------------- 666<object>:: 667 Indicates the object name for any type of object. 668 669<blob>:: 670 Indicates a blob object name. 671 672<tree>:: 673 Indicates a tree object name. 674 675<commit>:: 676 Indicates a commit object name. 677 678<tree-ish>:: 679 Indicates a tree, commit or tag object name. A 680 command that takes a <tree-ish> argument ultimately wants to 681 operate on a <tree> object but automatically dereferences 682 <commit> and <tag> objects that point at a <tree>. 683 684<commit-ish>:: 685 Indicates a commit or tag object name. A 686 command that takes a <commit-ish> argument ultimately wants to 687 operate on a <commit> object but automatically dereferences 688 <tag> objects that point at a <commit>. 689 690<type>:: 691 Indicates that an object type is required. 692 Currently one of: `blob`, `tree`, `commit`, or `tag`. 693 694<file>:: 695 Indicates a filename - almost always relative to the 696 root of the tree structure `GIT_INDEX_FILE` describes. 697 698Symbolic Identifiers 699-------------------- 700Any Git command accepting any <object> can also use the following 701symbolic notation: 702 703HEAD:: 704 indicates the head of the current branch. 705 706<tag>:: 707 a valid tag 'name' 708 (i.e. a `refs/tags/<tag>` reference). 709 710<head>:: 711 a valid head 'name' 712 (i.e. a `refs/heads/<head>` reference). 713 714For a more complete list of ways to spell object names, see 715"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7]. 716 717 718File/Directory Structure 719------------------------ 720 721Please see the linkgit:gitrepository-layout[5] document. 722 723Read linkgit:githooks[5] for more details about each hook. 724 725Higher level SCMs may provide and manage additional information in the 726`$GIT_DIR`. 727 728 729Terminology 730----------- 731Please see linkgit:gitglossary[7]. 732 733 734Environment Variables 735--------------------- 736Various Git commands use the following environment variables: 737 738The Git Repository 739~~~~~~~~~~~~~~~~~~ 740These environment variables apply to 'all' core Git commands. Nb: it 741is worth noting that they may be used/overridden by SCMS sitting above 742Git so take care if using Cogito etc. 743 744'GIT_INDEX_FILE':: 745 This environment allows the specification of an alternate 746 index file. If not specified, the default of `$GIT_DIR/index` 747 is used. 748 749'GIT_INDEX_VERSION':: 750 This environment variable allows the specification of an index 751 version for new repositories. It won't affect existing index 752 files. By default index file version [23] is used. 753 754'GIT_OBJECT_DIRECTORY':: 755 If the object storage directory is specified via this 756 environment variable then the sha1 directories are created 757 underneath - otherwise the default `$GIT_DIR/objects` 758 directory is used. 759 760'GIT_ALTERNATE_OBJECT_DIRECTORIES':: 761 Due to the immutable nature of Git objects, old objects can be 762 archived into shared, read-only directories. This variable 763 specifies a ":" separated (on Windows ";" separated) list 764 of Git object directories which can be used to search for Git 765 objects. New objects will not be written to these directories. 766 767'GIT_DIR':: 768 If the 'GIT_DIR' environment variable is set then it 769 specifies a path to use instead of the default `.git` 770 for the base of the repository. 771 The '--git-dir' command-line option also sets this value. 772 773'GIT_WORK_TREE':: 774 Set the path to the root of the working tree. 775 This can also be controlled by the '--work-tree' command-line 776 option and the core.worktree configuration variable. 777 778'GIT_NAMESPACE':: 779 Set the Git namespace; see linkgit:gitnamespaces[7] for details. 780 The '--namespace' command-line option also sets this value. 781 782'GIT_CEILING_DIRECTORIES':: 783 This should be a colon-separated list of absolute paths. If 784 set, it is a list of directories that Git should not chdir up 785 into while looking for a repository directory (useful for 786 excluding slow-loading network directories). It will not 787 exclude the current working directory or a GIT_DIR set on the 788 command line or in the environment. Normally, Git has to read 789 the entries in this list and resolve any symlink that 790 might be present in order to compare them with the current 791 directory. However, if even this access is slow, you 792 can add an empty entry to the list to tell Git that the 793 subsequent entries are not symlinks and needn't be resolved; 794 e.g., 795 'GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink'. 796 797'GIT_DISCOVERY_ACROSS_FILESYSTEM':: 798 When run in a directory that does not have ".git" repository 799 directory, Git tries to find such a directory in the parent 800 directories to find the top of the working tree, but by default it 801 does not cross filesystem boundaries. This environment variable 802 can be set to true to tell Git not to stop at filesystem 803 boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect 804 an explicit repository directory set via 'GIT_DIR' or on the 805 command line. 806 807Git Commits 808~~~~~~~~~~~ 809'GIT_AUTHOR_NAME':: 810'GIT_AUTHOR_EMAIL':: 811'GIT_AUTHOR_DATE':: 812'GIT_COMMITTER_NAME':: 813'GIT_COMMITTER_EMAIL':: 814'GIT_COMMITTER_DATE':: 815'EMAIL':: 816 see linkgit:git-commit-tree[1] 817 818Git Diffs 819~~~~~~~~~ 820'GIT_DIFF_OPTS':: 821 Only valid setting is "--unified=??" or "-u??" to set the 822 number of context lines shown when a unified diff is created. 823 This takes precedence over any "-U" or "--unified" option 824 value passed on the Git diff command line. 825 826'GIT_EXTERNAL_DIFF':: 827 When the environment variable 'GIT_EXTERNAL_DIFF' is set, the 828 program named by it is called, instead of the diff invocation 829 described above. For a path that is added, removed, or modified, 830 'GIT_EXTERNAL_DIFF' is called with 7 parameters: 831 832 path old-file old-hex old-mode new-file new-hex new-mode 833+ 834where: 835 836 <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the 837 contents of <old|new>, 838 <old|new>-hex:: are the 40-hexdigit SHA-1 hashes, 839 <old|new>-mode:: are the octal representation of the file modes. 840+ 841The file parameters can point at the user's working file 842(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file` 843when a new file is added), or a temporary file (e.g. `old-file` in the 844index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the 845temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits. 846+ 847For a path that is unmerged, 'GIT_EXTERNAL_DIFF' is called with 1 848parameter, <path>. 849+ 850For each path 'GIT_EXTERNAL_DIFF' is called, two environment variables, 851'GIT_DIFF_PATH_COUNTER' and 'GIT_DIFF_PATH_TOTAL' are set. 852 853'GIT_DIFF_PATH_COUNTER':: 854 A 1-based counter incremented by one for every path. 855 856'GIT_DIFF_PATH_TOTAL':: 857 The total number of paths. 858 859other 860~~~~~ 861'GIT_MERGE_VERBOSITY':: 862 A number controlling the amount of output shown by 863 the recursive merge strategy. Overrides merge.verbosity. 864 See linkgit:git-merge[1] 865 866'GIT_PAGER':: 867 This environment variable overrides `$PAGER`. If it is set 868 to an empty string or to the value "cat", Git will not launch 869 a pager. See also the `core.pager` option in 870 linkgit:git-config[1]. 871 872'GIT_EDITOR':: 873 This environment variable overrides `$EDITOR` and `$VISUAL`. 874 It is used by several Git commands when, on interactive mode, 875 an editor is to be launched. See also linkgit:git-var[1] 876 and the `core.editor` option in linkgit:git-config[1]. 877 878'GIT_SSH':: 879 If this environment variable is set then 'git fetch' 880 and 'git push' will use this command instead 881 of 'ssh' when they need to connect to a remote system. 882 The '$GIT_SSH' command will be given exactly two or 883 four arguments: the 'username@host' (or just 'host') 884 from the URL and the shell command to execute on that 885 remote system, optionally preceded by '-p' (literally) and 886 the 'port' from the URL when it specifies something other 887 than the default SSH port. 888+ 889To pass options to the program that you want to list in GIT_SSH 890you will need to wrap the program and options into a shell script, 891then set GIT_SSH to refer to the shell script. 892+ 893Usually it is easier to configure any desired options through your 894personal `.ssh/config` file. Please consult your ssh documentation 895for further details. 896 897'GIT_ASKPASS':: 898 If this environment variable is set, then Git commands which need to 899 acquire passwords or passphrases (e.g. for HTTP or IMAP authentication) 900 will call this program with a suitable prompt as command-line argument 901 and read the password from its STDOUT. See also the 'core.askpass' 902 option in linkgit:git-config[1]. 903 904'GIT_CONFIG_NOSYSTEM':: 905 Whether to skip reading settings from the system-wide 906 `$(prefix)/etc/gitconfig` file. This environment variable can 907 be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a 908 predictable environment for a picky script, or you can set it 909 temporarily to avoid using a buggy `/etc/gitconfig` file while 910 waiting for someone with sufficient permissions to fix it. 911 912'GIT_FLUSH':: 913 If this environment variable is set to "1", then commands such 914 as 'git blame' (in incremental mode), 'git rev-list', 'git log', 915 'git check-attr' and 'git check-ignore' will 916 force a flush of the output stream after each record have been 917 flushed. If this 918 variable is set to "0", the output of these commands will be done 919 using completely buffered I/O. If this environment variable is 920 not set, Git will choose buffered or record-oriented flushing 921 based on whether stdout appears to be redirected to a file or not. 922 923'GIT_TRACE':: 924 Enables general trace messages, e.g. alias expansion, built-in 925 command execution and external command execution. 926+ 927If this variable is set to "1", "2" or "true" (comparison 928is case insensitive), trace messages will be printed to 929stderr. 930+ 931If the variable is set to an integer value greater than 2 932and lower than 10 (strictly) then Git will interpret this 933value as an open file descriptor and will try to write the 934trace messages into this file descriptor. 935+ 936Alternatively, if the variable is set to an absolute path 937(starting with a '/' character), Git will interpret this 938as a file path and will try to write the trace messages 939into it. 940+ 941Unsetting the variable, or setting it to empty, "0" or 942"false" (case insensitive) disables trace messages. 943 944'GIT_TRACE_PACK_ACCESS':: 945 Enables trace messages for all accesses to any packs. For each 946 access, the pack file name and an offset in the pack is 947 recorded. This may be helpful for troubleshooting some 948 pack-related performance problems. 949 See 'GIT_TRACE' for available trace output options. 950 951'GIT_TRACE_PACKET':: 952 Enables trace messages for all packets coming in or out of a 953 given program. This can help with debugging object negotiation 954 or other protocol issues. Tracing is turned off at a packet 955 starting with "PACK". 956 See 'GIT_TRACE' for available trace output options. 957 958'GIT_TRACE_PERFORMANCE':: 959 Enables performance related trace messages, e.g. total execution 960 time of each Git command. 961 See 'GIT_TRACE' for available trace output options. 962 963'GIT_TRACE_SETUP':: 964 Enables trace messages printing the .git, working tree and current 965 working directory after Git has completed its setup phase. 966 See 'GIT_TRACE' for available trace output options. 967 968'GIT_TRACE_SHALLOW':: 969 Enables trace messages that can help debugging fetching / 970 cloning of shallow repositories. 971 See 'GIT_TRACE' for available trace output options. 972 973GIT_LITERAL_PATHSPECS:: 974 Setting this variable to `1` will cause Git to treat all 975 pathspecs literally, rather than as glob patterns. For example, 976 running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search 977 for commits that touch the path `*.c`, not any paths that the 978 glob `*.c` matches. You might want this if you are feeding 979 literal paths to Git (e.g., paths previously given to you by 980 `git ls-tree`, `--raw` diff output, etc). 981 982GIT_GLOB_PATHSPECS:: 983 Setting this variable to `1` will cause Git to treat all 984 pathspecs as glob patterns (aka "glob" magic). 985 986GIT_NOGLOB_PATHSPECS:: 987 Setting this variable to `1` will cause Git to treat all 988 pathspecs as literal (aka "literal" magic). 989 990GIT_ICASE_PATHSPECS:: 991 Setting this variable to `1` will cause Git to treat all 992 pathspecs as case-insensitive. 993 994'GIT_REFLOG_ACTION':: 995 When a ref is updated, reflog entries are created to keep 996 track of the reason why the ref was updated (which is 997 typically the name of the high-level command that updated 998 the ref), in addition to the old and new values of the ref. 999 A scripted Porcelain command can use set_reflog_action1000 helper function in `git-sh-setup` to set its name to this1001 variable when it is invoked as the top level command by the1002 end user, to be recorded in the body of the reflog.100310041005Discussion[[Discussion]]1006------------------------10071008More detail on the following is available from the1009link:user-manual.html#git-concepts[Git concepts chapter of the1010user-manual] and linkgit:gitcore-tutorial[7].10111012A Git project normally consists of a working directory with a ".git"1013subdirectory at the top level. The .git directory contains, among other1014things, a compressed object database representing the complete history1015of the project, an "index" file which links that history to the current1016contents of the working tree, and named pointers into that history such1017as tags and branch heads.10181019The object database contains objects of three main types: blobs, which1020hold file data; trees, which point to blobs and other trees to build up1021directory hierarchies; and commits, which each reference a single tree1022and some number of parent commits.10231024The commit, equivalent to what other systems call a "changeset" or1025"version", represents a step in the project's history, and each parent1026represents an immediately preceding step. Commits with more than one1027parent represent merges of independent lines of development.10281029All objects are named by the SHA-1 hash of their contents, normally1030written as a string of 40 hex digits. Such names are globally unique.1031The entire history leading up to a commit can be vouched for by signing1032just that commit. A fourth object type, the tag, is provided for this1033purpose.10341035When first created, objects are stored in individual files, but for1036efficiency may later be compressed together into "pack files".10371038Named pointers called refs mark interesting points in history. A ref1039may contain the SHA-1 name of an object or the name of another ref. Refs1040with names beginning `ref/head/` contain the SHA-1 name of the most1041recent commit (or "head") of a branch under development. SHA-1 names of1042tags of interest are stored under `ref/tags/`. A special ref named1043`HEAD` contains the name of the currently checked-out branch.10441045The index file is initialized with a list of all paths and, for each1046path, a blob object and a set of attributes. The blob object represents1047the contents of the file as of the head of the current branch. The1048attributes (last modified time, size, etc.) are taken from the1049corresponding file in the working tree. Subsequent changes to the1050working tree can be found by comparing these attributes. The index may1051be updated with new content, and new commits may be created from the1052content stored in the index.10531054The index is also capable of storing multiple entries (called "stages")1055for a given pathname. These stages are used to hold the various1056unmerged version of a file when a merge is in progress.10571058FURTHER DOCUMENTATION1059---------------------10601061See the references in the "description" section to get started1062using Git.
