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. 457 458--help:: 459 Prints the synopsis and a list of the most commonly used 460 commands. If the option '--all' or '-a' is given then all 461 available commands are printed. If a Git command is named this 462 option will bring up the manual page for that command. 463+ 464Other options are available to control how the manual page is 465displayed. See linkgit:git-help[1] for more information, 466because `git --help ...` is converted internally into `git 467help ...`. 468 469-C <path>:: 470 Run as if git was started in '<path>' instead of the current working 471 directory. When multiple `-C` options are given, each subsequent 472 non-absolute `-C <path>` is interpreted relative to the preceding `-C 473 <path>`. 474+ 475This option affects options that expect path name like `--git-dir` and 476`--work-tree` in that their interpretations of the path names would be 477made relative to the working directory caused by the `-C` option. For 478example the following invocations are equivalent: 479 480 git --git-dir=a.git --work-tree=b -C c status 481 git --git-dir=c/a.git --work-tree=c/b status 482 483-c <name>=<value>:: 484 Pass a configuration parameter to the command. The value 485 given will override values from configuration files. 486 The <name> is expected in the same format as listed by 487 'git config' (subkeys separated by dots). 488+ 489Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets 490`foo.bar` to the boolean true value (just like `[foo]bar` would in a 491config file). Including the equals but with an empty value (like `git -c 492foo.bar= ...`) sets `foo.bar` to the empty string. 493 494--exec-path[=<path>]:: 495 Path to wherever your core Git programs are installed. 496 This can also be controlled by setting the GIT_EXEC_PATH 497 environment variable. If no path is given, 'git' will print 498 the current setting and then exit. 499 500--html-path:: 501 Print the path, without trailing slash, where Git's HTML 502 documentation is installed and exit. 503 504--man-path:: 505 Print the manpath (see `man(1)`) for the man pages for 506 this version of Git and exit. 507 508--info-path:: 509 Print the path where the Info files documenting this 510 version of Git are installed and exit. 511 512-p:: 513--paginate:: 514 Pipe all output into 'less' (or if set, $PAGER) if standard 515 output is a terminal. This overrides the `pager.<cmd>` 516 configuration options (see the "Configuration Mechanism" section 517 below). 518 519--no-pager:: 520 Do not pipe Git output into a pager. 521 522--git-dir=<path>:: 523 Set the path to the repository. This can also be controlled by 524 setting the GIT_DIR environment variable. It can be an absolute 525 path or relative path to current working directory. 526 527--work-tree=<path>:: 528 Set the path to the working tree. It can be an absolute path 529 or a path relative to the current working directory. 530 This can also be controlled by setting the GIT_WORK_TREE 531 environment variable and the core.worktree configuration 532 variable (see core.worktree in linkgit:git-config[1] for a 533 more detailed discussion). 534 535--namespace=<path>:: 536 Set the Git namespace. See linkgit:gitnamespaces[7] for more 537 details. Equivalent to setting the `GIT_NAMESPACE` environment 538 variable. 539 540--bare:: 541 Treat the repository as a bare repository. If GIT_DIR 542 environment is not set, it is set to the current working 543 directory. 544 545--no-replace-objects:: 546 Do not use replacement refs to replace Git objects. See 547 linkgit:git-replace[1] for more information. 548 549--literal-pathspecs:: 550 Treat pathspecs literally (i.e. no globbing, no pathspec magic). 551 This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment 552 variable to `1`. 553 554--glob-pathspecs:: 555 Add "glob" magic to all pathspec. This is equivalent to setting 556 the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling 557 globbing on individual pathspecs can be done using pathspec 558 magic ":(literal)" 559 560--noglob-pathspecs:: 561 Add "literal" magic to all pathspec. This is equivalent to setting 562 the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling 563 globbing on individual pathspecs can be done using pathspec 564 magic ":(glob)" 565 566--icase-pathspecs:: 567 Add "icase" magic to all pathspec. This is equivalent to setting 568 the `GIT_ICASE_PATHSPECS` environment variable to `1`. 569 570GIT COMMANDS 571------------ 572 573We divide Git into high level ("porcelain") commands and low level 574("plumbing") commands. 575 576High-level commands (porcelain) 577------------------------------- 578 579We separate the porcelain commands into the main commands and some 580ancillary user utilities. 581 582Main porcelain commands 583~~~~~~~~~~~~~~~~~~~~~~~ 584 585include::cmds-mainporcelain.txt[] 586 587Ancillary Commands 588~~~~~~~~~~~~~~~~~~ 589Manipulators: 590 591include::cmds-ancillarymanipulators.txt[] 592 593Interrogators: 594 595include::cmds-ancillaryinterrogators.txt[] 596 597 598Interacting with Others 599~~~~~~~~~~~~~~~~~~~~~~~ 600 601These commands are to interact with foreign SCM and with other 602people via patch over e-mail. 603 604include::cmds-foreignscminterface.txt[] 605 606 607Low-level commands (plumbing) 608----------------------------- 609 610Although Git includes its 611own porcelain layer, its low-level commands are sufficient to support 612development of alternative porcelains. Developers of such porcelains 613might start by reading about linkgit:git-update-index[1] and 614linkgit:git-read-tree[1]. 615 616The interface (input, output, set of options and the semantics) 617to these low-level commands are meant to be a lot more stable 618than Porcelain level commands, because these commands are 619primarily for scripted use. The interface to Porcelain commands 620on the other hand are subject to change in order to improve the 621end user experience. 622 623The following description divides 624the low-level commands into commands that manipulate objects (in 625the repository, index, and working tree), commands that interrogate and 626compare objects, and commands that move objects and references between 627repositories. 628 629 630Manipulation commands 631~~~~~~~~~~~~~~~~~~~~~ 632 633include::cmds-plumbingmanipulators.txt[] 634 635 636Interrogation commands 637~~~~~~~~~~~~~~~~~~~~~~ 638 639include::cmds-plumbinginterrogators.txt[] 640 641In general, the interrogate commands do not touch the files in 642the working tree. 643 644 645Synching repositories 646~~~~~~~~~~~~~~~~~~~~~ 647 648include::cmds-synchingrepositories.txt[] 649 650The following are helper commands used by the above; end users 651typically do not use them directly. 652 653include::cmds-synchelpers.txt[] 654 655 656Internal helper commands 657~~~~~~~~~~~~~~~~~~~~~~~~ 658 659These are internal helper commands used by other commands; end 660users typically do not use them directly. 661 662include::cmds-purehelpers.txt[] 663 664 665Configuration Mechanism 666----------------------- 667 668Git uses a simple text format to store customizations that are per 669repository and are per user. Such a configuration file may look 670like this: 671 672------------ 673# 674# A '#' or ';' character indicates a comment. 675# 676 677; core variables 678[core] 679 ; Don't trust file modes 680 filemode = false 681 682; user identity 683[user] 684 name = "Junio C Hamano" 685 email = "gitster@pobox.com" 686 687------------ 688 689Various commands read from the configuration file and adjust 690their operation accordingly. See linkgit:git-config[1] for a 691list and more details about the configuration mechanism. 692 693 694Identifier Terminology 695---------------------- 696<object>:: 697 Indicates the object name for any type of object. 698 699<blob>:: 700 Indicates a blob object name. 701 702<tree>:: 703 Indicates a tree object name. 704 705<commit>:: 706 Indicates a commit object name. 707 708<tree-ish>:: 709 Indicates a tree, commit or tag object name. A 710 command that takes a <tree-ish> argument ultimately wants to 711 operate on a <tree> object but automatically dereferences 712 <commit> and <tag> objects that point at a <tree>. 713 714<commit-ish>:: 715 Indicates a commit or tag object name. A 716 command that takes a <commit-ish> argument ultimately wants to 717 operate on a <commit> object but automatically dereferences 718 <tag> objects that point at a <commit>. 719 720<type>:: 721 Indicates that an object type is required. 722 Currently one of: `blob`, `tree`, `commit`, or `tag`. 723 724<file>:: 725 Indicates a filename - almost always relative to the 726 root of the tree structure `GIT_INDEX_FILE` describes. 727 728Symbolic Identifiers 729-------------------- 730Any Git command accepting any <object> can also use the following 731symbolic notation: 732 733HEAD:: 734 indicates the head of the current branch. 735 736<tag>:: 737 a valid tag 'name' 738 (i.e. a `refs/tags/<tag>` reference). 739 740<head>:: 741 a valid head 'name' 742 (i.e. a `refs/heads/<head>` reference). 743 744For a more complete list of ways to spell object names, see 745"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7]. 746 747 748File/Directory Structure 749------------------------ 750 751Please see the linkgit:gitrepository-layout[5] document. 752 753Read linkgit:githooks[5] for more details about each hook. 754 755Higher level SCMs may provide and manage additional information in the 756`$GIT_DIR`. 757 758 759Terminology 760----------- 761Please see linkgit:gitglossary[7]. 762 763 764Environment Variables 765--------------------- 766Various Git commands use the following environment variables: 767 768The Git Repository 769~~~~~~~~~~~~~~~~~~ 770These environment variables apply to 'all' core Git commands. Nb: it 771is worth noting that they may be used/overridden by SCMS sitting above 772Git so take care if using Cogito etc. 773 774'GIT_INDEX_FILE':: 775 This environment allows the specification of an alternate 776 index file. If not specified, the default of `$GIT_DIR/index` 777 is used. 778 779'GIT_INDEX_VERSION':: 780 This environment variable allows the specification of an index 781 version for new repositories. It won't affect existing index 782 files. By default index file version 2 or 3 is used. See 783 linkgit:git-update-index[1] for more information. 784 785'GIT_OBJECT_DIRECTORY':: 786 If the object storage directory is specified via this 787 environment variable then the sha1 directories are created 788 underneath - otherwise the default `$GIT_DIR/objects` 789 directory is used. 790 791'GIT_ALTERNATE_OBJECT_DIRECTORIES':: 792 Due to the immutable nature of Git objects, old objects can be 793 archived into shared, read-only directories. This variable 794 specifies a ":" separated (on Windows ";" separated) list 795 of Git object directories which can be used to search for Git 796 objects. New objects will not be written to these directories. 797 798'GIT_DIR':: 799 If the 'GIT_DIR' environment variable is set then it 800 specifies a path to use instead of the default `.git` 801 for the base of the repository. 802 The '--git-dir' command-line option also sets this value. 803 804'GIT_WORK_TREE':: 805 Set the path to the root of the working tree. 806 This can also be controlled by the '--work-tree' command-line 807 option and the core.worktree configuration variable. 808 809'GIT_NAMESPACE':: 810 Set the Git namespace; see linkgit:gitnamespaces[7] for details. 811 The '--namespace' command-line option also sets this value. 812 813'GIT_CEILING_DIRECTORIES':: 814 This should be a colon-separated list of absolute paths. If 815 set, it is a list of directories that Git should not chdir up 816 into while looking for a repository directory (useful for 817 excluding slow-loading network directories). It will not 818 exclude the current working directory or a GIT_DIR set on the 819 command line or in the environment. Normally, Git has to read 820 the entries in this list and resolve any symlink that 821 might be present in order to compare them with the current 822 directory. However, if even this access is slow, you 823 can add an empty entry to the list to tell Git that the 824 subsequent entries are not symlinks and needn't be resolved; 825 e.g., 826 'GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink'. 827 828'GIT_DISCOVERY_ACROSS_FILESYSTEM':: 829 When run in a directory that does not have ".git" repository 830 directory, Git tries to find such a directory in the parent 831 directories to find the top of the working tree, but by default it 832 does not cross filesystem boundaries. This environment variable 833 can be set to true to tell Git not to stop at filesystem 834 boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect 835 an explicit repository directory set via 'GIT_DIR' or on the 836 command line. 837 838'GIT_COMMON_DIR':: 839 If this variable is set to a path, non-worktree files that are 840 normally in $GIT_DIR will be taken from this path 841 instead. Worktree-specific files such as HEAD or index are 842 taken from $GIT_DIR. See linkgit:gitrepository-layout[5] and 843 the section 'MULTIPLE CHECKOUT MODE' in linkgit:checkout[1] 844 details. This variable has lower precedence than other path 845 variables such as GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY... 846 847Git Commits 848~~~~~~~~~~~ 849'GIT_AUTHOR_NAME':: 850'GIT_AUTHOR_EMAIL':: 851'GIT_AUTHOR_DATE':: 852'GIT_COMMITTER_NAME':: 853'GIT_COMMITTER_EMAIL':: 854'GIT_COMMITTER_DATE':: 855'EMAIL':: 856 see linkgit:git-commit-tree[1] 857 858Git Diffs 859~~~~~~~~~ 860'GIT_DIFF_OPTS':: 861 Only valid setting is "--unified=??" or "-u??" to set the 862 number of context lines shown when a unified diff is created. 863 This takes precedence over any "-U" or "--unified" option 864 value passed on the Git diff command line. 865 866'GIT_EXTERNAL_DIFF':: 867 When the environment variable 'GIT_EXTERNAL_DIFF' is set, the 868 program named by it is called, instead of the diff invocation 869 described above. For a path that is added, removed, or modified, 870 'GIT_EXTERNAL_DIFF' is called with 7 parameters: 871 872 path old-file old-hex old-mode new-file new-hex new-mode 873+ 874where: 875 876 <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the 877 contents of <old|new>, 878 <old|new>-hex:: are the 40-hexdigit SHA-1 hashes, 879 <old|new>-mode:: are the octal representation of the file modes. 880+ 881The file parameters can point at the user's working file 882(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file` 883when a new file is added), or a temporary file (e.g. `old-file` in the 884index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the 885temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits. 886+ 887For a path that is unmerged, 'GIT_EXTERNAL_DIFF' is called with 1 888parameter, <path>. 889+ 890For each path 'GIT_EXTERNAL_DIFF' is called, two environment variables, 891'GIT_DIFF_PATH_COUNTER' and 'GIT_DIFF_PATH_TOTAL' are set. 892 893'GIT_DIFF_PATH_COUNTER':: 894 A 1-based counter incremented by one for every path. 895 896'GIT_DIFF_PATH_TOTAL':: 897 The total number of paths. 898 899other 900~~~~~ 901'GIT_MERGE_VERBOSITY':: 902 A number controlling the amount of output shown by 903 the recursive merge strategy. Overrides merge.verbosity. 904 See linkgit:git-merge[1] 905 906'GIT_PAGER':: 907 This environment variable overrides `$PAGER`. If it is set 908 to an empty string or to the value "cat", Git will not launch 909 a pager. See also the `core.pager` option in 910 linkgit:git-config[1]. 911 912'GIT_EDITOR':: 913 This environment variable overrides `$EDITOR` and `$VISUAL`. 914 It is used by several Git commands when, on interactive mode, 915 an editor is to be launched. See also linkgit:git-var[1] 916 and the `core.editor` option in linkgit:git-config[1]. 917 918'GIT_SSH':: 919'GIT_SSH_COMMAND':: 920 If either of these environment variables is set then 'git fetch' 921 and 'git push' will use the specified command instead of 'ssh' 922 when they need to connect to a remote system. 923 The command will be given exactly two or four arguments: the 924 'username@host' (or just 'host') from the URL and the shell 925 command to execute on that remote system, optionally preceded by 926 '-p' (literally) and the 'port' from the URL when it specifies 927 something other than the default SSH port. 928+ 929`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted 930by the shell, which allows additional arguments to be included. 931`$GIT_SSH` on the other hand must be just the path to a program 932(which can be a wrapper shell script, if additional arguments are 933needed). 934+ 935Usually it is easier to configure any desired options through your 936personal `.ssh/config` file. Please consult your ssh documentation 937for further details. 938 939'GIT_ASKPASS':: 940 If this environment variable is set, then Git commands which need to 941 acquire passwords or passphrases (e.g. for HTTP or IMAP authentication) 942 will call this program with a suitable prompt as command-line argument 943 and read the password from its STDOUT. See also the 'core.askPass' 944 option in linkgit:git-config[1]. 945 946'GIT_TERMINAL_PROMPT':: 947 If this environment variable is set to `0`, git will not prompt 948 on the terminal (e.g., when asking for HTTP authentication). 949 950'GIT_CONFIG_NOSYSTEM':: 951 Whether to skip reading settings from the system-wide 952 `$(prefix)/etc/gitconfig` file. This environment variable can 953 be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a 954 predictable environment for a picky script, or you can set it 955 temporarily to avoid using a buggy `/etc/gitconfig` file while 956 waiting for someone with sufficient permissions to fix it. 957 958'GIT_FLUSH':: 959 If this environment variable is set to "1", then commands such 960 as 'git blame' (in incremental mode), 'git rev-list', 'git log', 961 'git check-attr' and 'git check-ignore' will 962 force a flush of the output stream after each record have been 963 flushed. If this 964 variable is set to "0", the output of these commands will be done 965 using completely buffered I/O. If this environment variable is 966 not set, Git will choose buffered or record-oriented flushing 967 based on whether stdout appears to be redirected to a file or not. 968 969'GIT_TRACE':: 970 Enables general trace messages, e.g. alias expansion, built-in 971 command execution and external command execution. 972+ 973If this variable is set to "1", "2" or "true" (comparison 974is case insensitive), trace messages will be printed to 975stderr. 976+ 977If the variable is set to an integer value greater than 2 978and lower than 10 (strictly) then Git will interpret this 979value as an open file descriptor and will try to write the 980trace messages into this file descriptor. 981+ 982Alternatively, if the variable is set to an absolute path 983(starting with a '/' character), Git will interpret this 984as a file path and will try to write the trace messages 985into it. 986+ 987Unsetting the variable, or setting it to empty, "0" or 988"false" (case insensitive) disables trace messages. 989 990'GIT_TRACE_PACK_ACCESS':: 991 Enables trace messages for all accesses to any packs. For each 992 access, the pack file name and an offset in the pack is 993 recorded. This may be helpful for troubleshooting some 994 pack-related performance problems. 995 See 'GIT_TRACE' for available trace output options. 996 997'GIT_TRACE_PACKET':: 998 Enables trace messages for all packets coming in or out of a 999 given program. This can help with debugging object negotiation1000 or other protocol issues. Tracing is turned off at a packet1001 starting with "PACK".1002 See 'GIT_TRACE' for available trace output options.10031004'GIT_TRACE_PERFORMANCE'::1005 Enables performance related trace messages, e.g. total execution1006 time of each Git command.1007 See 'GIT_TRACE' for available trace output options.10081009'GIT_TRACE_SETUP'::1010 Enables trace messages printing the .git, working tree and current1011 working directory after Git has completed its setup phase.1012 See 'GIT_TRACE' for available trace output options.10131014'GIT_TRACE_SHALLOW'::1015 Enables trace messages that can help debugging fetching /1016 cloning of shallow repositories.1017 See 'GIT_TRACE' for available trace output options.10181019GIT_LITERAL_PATHSPECS::1020 Setting this variable to `1` will cause Git to treat all1021 pathspecs literally, rather than as glob patterns. For example,1022 running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search1023 for commits that touch the path `*.c`, not any paths that the1024 glob `*.c` matches. You might want this if you are feeding1025 literal paths to Git (e.g., paths previously given to you by1026 `git ls-tree`, `--raw` diff output, etc).10271028GIT_GLOB_PATHSPECS::1029 Setting this variable to `1` will cause Git to treat all1030 pathspecs as glob patterns (aka "glob" magic).10311032GIT_NOGLOB_PATHSPECS::1033 Setting this variable to `1` will cause Git to treat all1034 pathspecs as literal (aka "literal" magic).10351036GIT_ICASE_PATHSPECS::1037 Setting this variable to `1` will cause Git to treat all1038 pathspecs as case-insensitive.10391040'GIT_REFLOG_ACTION'::1041 When a ref is updated, reflog entries are created to keep1042 track of the reason why the ref was updated (which is1043 typically the name of the high-level command that updated1044 the ref), in addition to the old and new values of the ref.1045 A scripted Porcelain command can use set_reflog_action1046 helper function in `git-sh-setup` to set its name to this1047 variable when it is invoked as the top level command by the1048 end user, to be recorded in the body of the reflog.10491050`GIT_REF_PARANOIA`::1051 If set to `1`, include broken or badly named refs when iterating1052 over lists of refs. In a normal, non-corrupted repository, this1053 does nothing. However, enabling it may help git to detect and1054 abort some operations in the presence of broken refs. Git sets1055 this variable automatically when performing destructive1056 operations like linkgit:git-prune[1]. You should not need to set1057 it yourself unless you want to be paranoid about making sure1058 an operation has touched every ref (e.g., because you are1059 cloning a repository to make a backup).106010611062Discussion[[Discussion]]1063------------------------10641065More detail on the following is available from the1066link:user-manual.html#git-concepts[Git concepts chapter of the1067user-manual] and linkgit:gitcore-tutorial[7].10681069A Git project normally consists of a working directory with a ".git"1070subdirectory at the top level. The .git directory contains, among other1071things, a compressed object database representing the complete history1072of the project, an "index" file which links that history to the current1073contents of the working tree, and named pointers into that history such1074as tags and branch heads.10751076The object database contains objects of three main types: blobs, which1077hold file data; trees, which point to blobs and other trees to build up1078directory hierarchies; and commits, which each reference a single tree1079and some number of parent commits.10801081The commit, equivalent to what other systems call a "changeset" or1082"version", represents a step in the project's history, and each parent1083represents an immediately preceding step. Commits with more than one1084parent represent merges of independent lines of development.10851086All objects are named by the SHA-1 hash of their contents, normally1087written as a string of 40 hex digits. Such names are globally unique.1088The entire history leading up to a commit can be vouched for by signing1089just that commit. A fourth object type, the tag, is provided for this1090purpose.10911092When first created, objects are stored in individual files, but for1093efficiency may later be compressed together into "pack files".10941095Named pointers called refs mark interesting points in history. A ref1096may contain the SHA-1 name of an object or the name of another ref. Refs1097with names beginning `ref/head/` contain the SHA-1 name of the most1098recent commit (or "head") of a branch under development. SHA-1 names of1099tags of interest are stored under `ref/tags/`. A special ref named1100`HEAD` contains the name of the currently checked-out branch.11011102The index file is initialized with a list of all paths and, for each1103path, a blob object and a set of attributes. The blob object represents1104the contents of the file as of the head of the current branch. The1105attributes (last modified time, size, etc.) are taken from the1106corresponding file in the working tree. Subsequent changes to the1107working tree can be found by comparing these attributes. The index may1108be updated with new content, and new commits may be created from the1109content stored in the index.11101111The index is also capable of storing multiple entries (called "stages")1112for a given pathname. These stages are used to hold the various1113unmerged version of a file when a merge is in progress.11141115FURTHER DOCUMENTATION1116---------------------11171118See the references in the "description" section to get started1119using Git.
