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 34A formatted and hyperlinked copy of the latest Git documentation 35can be viewed at `https://git.github.io/htmldocs/git.html`. 36 37ifdef::stalenotes[] 38[NOTE] 39============ 40 41You are reading the documentation for the

Git suite version that the 'git' program came from. 522 523--help:: 524 Prints the synopsis and a list of the most commonly used 525 commands. If the option `--all` or `-a` is given then all 526 available commands are printed. If a Git command is named this 527 option will bring up the manual page for that command. 528+ 529Other options are available to control how the manual page is 530displayed. See linkgit:git-help[1] for more information, 531because `git --help ...` is converted internally into `git 532help ...`. 533 534-C <path>:: 535 Run as if git was started in '<path>' instead of the current working 536 directory. When multiple `-C` options are given, each subsequent 537 non-absolute `-C <path>` is interpreted relative to the preceding `-C 538 <path>`. 539+ 540This option affects options that expect path name like `--git-dir` and 541`--work-tree` in that their interpretations of the path names would be 542made relative to the working directory caused by the `-C` option. For 543example the following invocations are equivalent: 544 545 git --git-dir=a.git --work-tree=b -C c status 546 git --git-dir=c/a.git --work-tree=c/b status 547 548-c <name>=<value>:: 549 Pass a configuration parameter to the command. The value 550 given will override values from configuration files. 551 The <name> is expected in the same format as listed by 552 'git config' (subkeys separated by dots). 553+ 554Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets 555`foo.bar` to the boolean true value (just like `[foo]bar` would in a 556config file). Including the equals but with an empty value (like `git -c 557foo.bar= ...`) sets `foo.bar` to the empty string. 558 559--exec-path[=<path>]:: 560 Path to wherever your core Git programs are installed. 561 This can also be controlled by setting the GIT_EXEC_PATH 562 environment variable. If no path is given, 'git' will print 563 the current setting and then exit. 564 565--html-path:: 566 Print the path, without trailing slash, where Git's HTML 567 documentation is installed and exit. 568 569--man-path:: 570 Print the manpath (see `man(1)`) for the man pages for 571 this version of Git and exit. 572 573--info-path:: 574 Print the path where the Info files documenting this 575 version of Git are installed and exit. 576 577-p:: 578--paginate:: 579 Pipe all output into 'less' (or if set, $PAGER) if standard 580 output is a terminal. This overrides the `pager.<cmd>` 581 configuration options (see the "Configuration Mechanism" section 582 below). 583 584--no-pager:: 585 Do not pipe Git output into a pager. 586 587--git-dir=<path>:: 588 Set the path to the repository. This can also be controlled by 589 setting the `GIT_DIR` environment variable. It can be an absolute 590 path or relative path to current working directory. 591 592--work-tree=<path>:: 593 Set the path to the working tree. It can be an absolute path 594 or a path relative to the current working directory. 595 This can also be controlled by setting the GIT_WORK_TREE 596 environment variable and the core.worktree configuration 597 variable (see core.worktree in linkgit:git-config[1] for a 598 more detailed discussion). 599 600--namespace=<path>:: 601 Set the Git namespace. See linkgit:gitnamespaces[7] for more 602 details. Equivalent to setting the `GIT_NAMESPACE` environment 603 variable. 604 605--bare:: 606 Treat the repository as a bare repository. If GIT_DIR 607 environment is not set, it is set to the current working 608 directory. 609 610--no-replace-objects:: 611 Do not use replacement refs to replace Git objects. See 612 linkgit:git-replace[1] for more information. 613 614--literal-pathspecs:: 615 Treat pathspecs literally (i.e. no globbing, no pathspec magic). 616 This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment 617 variable to `1`. 618 619--glob-pathspecs:: 620 Add "glob" magic to all pathspec. This is equivalent to setting 621 the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling 622 globbing on individual pathspecs can be done using pathspec 623 magic ":(literal)" 624 625--noglob-pathspecs:: 626 Add "literal" magic to all pathspec. This is equivalent to setting 627 the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling 628 globbing on individual pathspecs can be done using pathspec 629 magic ":(glob)" 630 631--icase-pathspecs:: 632 Add "icase" magic to all pathspec. This is equivalent to setting 633 the `GIT_ICASE_PATHSPECS` environment variable to `1`. 634 635GIT COMMANDS 636------------ 637 638We divide Git into high level ("porcelain") commands and low level 639("plumbing") commands. 640 641High-level commands (porcelain) 642------------------------------- 643 644We separate the porcelain commands into the main commands and some 645ancillary user utilities. 646 647Main porcelain commands 648~~~~~~~~~~~~~~~~~~~~~~~ 649 650include::cmds-mainporcelain.txt[] 651 652Ancillary Commands 653~~~~~~~~~~~~~~~~~~ 654Manipulators: 655 656include::cmds-ancillarymanipulators.txt[] 657 658Interrogators: 659 660include::cmds-ancillaryinterrogators.txt[] 661 662 663Interacting with Others 664~~~~~~~~~~~~~~~~~~~~~~~ 665 666These commands are to interact with foreign SCM and with other 667people via patch over e-mail. 668 669include::cmds-foreignscminterface.txt[] 670 671 672Low-level commands (plumbing) 673----------------------------- 674 675Although Git includes its 676own porcelain layer, its low-level commands are sufficient to support 677development of alternative porcelains. Developers of such porcelains 678might start by reading about linkgit:git-update-index[1] and 679linkgit:git-read-tree[1]. 680 681The interface (input, output, set of options and the semantics) 682to these low-level commands are meant to be a lot more stable 683than Porcelain level commands, because these commands are 684primarily for scripted use. The interface to Porcelain commands 685on the other hand are subject to change in order to improve the 686end user experience. 687 688The following description divides 689the low-level commands into commands that manipulate objects (in 690the repository, index, and working tree), commands that interrogate and 691compare objects, and commands that move objects and references between 692repositories. 693 694 695Manipulation commands 696~~~~~~~~~~~~~~~~~~~~~ 697 698include::cmds-plumbingmanipulators.txt[] 699 700 701Interrogation commands 702~~~~~~~~~~~~~~~~~~~~~~ 703 704include::cmds-plumbinginterrogators.txt[] 705 706In general, the interrogate commands do not touch the files in 707the working tree. 708 709 710Synching repositories 711~~~~~~~~~~~~~~~~~~~~~ 712 713include::cmds-synchingrepositories.txt[] 714 715The following are helper commands used by the above; end users 716typically do not use them directly. 717 718include::cmds-synchelpers.txt[] 719 720 721Internal helper commands 722~~~~~~~~~~~~~~~~~~~~~~~~ 723 724These are internal helper commands used by other commands; end 725users typically do not use them directly. 726 727include::cmds-purehelpers.txt[] 728 729 730Configuration Mechanism 731----------------------- 732 733Git uses a simple text format to store customizations that are per 734repository and are per user. Such a configuration file may look 735like this: 736 737------------ 738# 739# A '#' or ';' character indicates a comment. 740# 741 742; core variables 743[core] 744 ; Don't trust file modes 745 filemode = false 746 747; user identity 748[user] 749 name = "Junio C Hamano" 750 email = "gitster@pobox.com" 751 752------------ 753 754Various commands read from the configuration file and adjust 755their operation accordingly. See linkgit:git-config[1] for a 756list and more details about the configuration mechanism. 757 758 759Identifier Terminology 760---------------------- 761<object>:: 762 Indicates the object name for any type of object. 763 764<blob>:: 765 Indicates a blob object name. 766 767<tree>:: 768 Indicates a tree object name. 769 770<commit>:: 771 Indicates a commit object name. 772 773<tree-ish>:: 774 Indicates a tree, commit or tag object name. A 775 command that takes a <tree-ish> argument ultimately wants to 776 operate on a <tree> object but automatically dereferences 777 <commit> and <tag> objects that point at a <tree>. 778 779<commit-ish>:: 780 Indicates a commit or tag object name. A 781 command that takes a <commit-ish> argument ultimately wants to 782 operate on a <commit> object but automatically dereferences 783 <tag> objects that point at a <commit>. 784 785<type>:: 786 Indicates that an object type is required. 787 Currently one of: `blob`, `tree`, `commit`, or `tag`. 788 789<file>:: 790 Indicates a filename - almost always relative to the 791 root of the tree structure `GIT_INDEX_FILE` describes. 792 793Symbolic Identifiers 794-------------------- 795Any Git command accepting any <object> can also use the following 796symbolic notation: 797 798HEAD:: 799 indicates the head of the current branch. 800 801<tag>:: 802 a valid tag 'name' 803 (i.e. a `refs/tags/<tag>` reference). 804 805<head>:: 806 a valid head 'name' 807 (i.e. a `refs/heads/<head>` reference). 808 809For a more complete list of ways to spell object names, see 810"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7]. 811 812 813File/Directory Structure 814------------------------ 815 816Please see the linkgit:gitrepository-layout[5] document. 817 818Read linkgit:githooks[5] for more details about each hook. 819 820Higher level SCMs may provide and manage additional information in the 821`$GIT_DIR`. 822 823 824Terminology 825----------- 826Please see linkgit:gitglossary[7]. 827 828 829Environment Variables 830--------------------- 831Various Git commands use the following environment variables: 832 833The Git Repository 834~~~~~~~~~~~~~~~~~~ 835These environment variables apply to 'all' core Git commands. Nb: it 836is worth noting that they may be used/overridden by SCMS sitting above 837Git so take care if using a foreign front-end. 838 839`GIT_INDEX_FILE`:: 840 This environment allows the specification of an alternate 841 index file. If not specified, the default of `$GIT_DIR/index` 842 is used. 843 844`GIT_INDEX_VERSION`:: 845 This environment variable allows the specification of an index 846 version for new repositories. It won't affect existing index 847 files. By default index file version 2 or 3 is used. See 848 linkgit:git-update-index[1] for more information. 849 850`GIT_OBJECT_DIRECTORY`:: 851 If the object storage directory is specified via this 852 environment variable then the sha1 directories are created 853 underneath - otherwise the default `$GIT_DIR/objects` 854 directory is used. 855 856`GIT_ALTERNATE_OBJECT_DIRECTORIES`:: 857 Due to the immutable nature of Git objects, old objects can be 858 archived into shared, read-only directories. This variable 859 specifies a ":" separated (on Windows ";" separated) list 860 of Git object directories which can be used to search for Git 861 objects. New objects will not be written to these directories. 862+ 863 Entries that begin with `"` (double-quote) will be interpreted 864 as C-style quoted paths, removing leading and trailing 865 double-quotes and respecting backslash escapes. E.g., the value 866 `"path-with-\"-and-:-in-it":vanilla-path` has two paths: 867 `path-with-"-and-:-in-it` and `vanilla-path`. 868 869`GIT_DIR`:: 870 If the `GIT_DIR` environment variable is set then it 871 specifies a path to use instead of the default `.git` 872 for the base of the repository. 873 The `--git-dir` command-line option also sets this value. 874 875`GIT_WORK_TREE`:: 876 Set the path to the root of the working tree. 877 This can also be controlled by the `--work-tree` command-line 878 option and the core.worktree configuration variable. 879 880`GIT_NAMESPACE`:: 881 Set the Git namespace; see linkgit:gitnamespaces[7] for details. 882 The `--namespace` command-line option also sets this value. 883 884`GIT_CEILING_DIRECTORIES`:: 885 This should be a colon-separated list of absolute paths. If 886 set, it is a list of directories that Git should not chdir up 887 into while looking for a repository directory (useful for 888 excluding slow-loading network directories). It will not 889 exclude the current working directory or a GIT_DIR set on the 890 command line or in the environment. Normally, Git has to read 891 the entries in this list and resolve any symlink that 892 might be present in order to compare them with the current 893 directory. However, if even this access is slow, you 894 can add an empty entry to the list to tell Git that the 895 subsequent entries are not symlinks and needn't be resolved; 896 e.g., 897 `GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink`. 898 899`GIT_DISCOVERY_ACROSS_FILESYSTEM`:: 900 When run in a directory that does not have ".git" repository 901 directory, Git tries to find such a directory in the parent 902 directories to find the top of the working tree, but by default it 903 does not cross filesystem boundaries. This environment variable 904 can be set to true to tell Git not to stop at filesystem 905 boundaries. Like `GIT_CEILING_DIRECTORIES`, this will not affect 906 an explicit repository directory set via `GIT_DIR` or on the 907 command line. 908 909`GIT_COMMON_DIR`:: 910 If this variable is set to a path, non-worktree files that are 911 normally in $GIT_DIR will be taken from this path 912 instead. Worktree-specific files such as HEAD or index are 913 taken from $GIT_DIR. See linkgit:gitrepository-layout[5] and 914 linkgit:git-worktree[1] for 915 details. This variable has lower precedence than other path 916 variables such as GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY... 917 918Git Commits 919~~~~~~~~~~~ 920`GIT_AUTHOR_NAME`:: 921`GIT_AUTHOR_EMAIL`:: 922`GIT_AUTHOR_DATE`:: 923`GIT_COMMITTER_NAME`:: 924`GIT_COMMITTER_EMAIL`:: 925`GIT_COMMITTER_DATE`:: 926'EMAIL':: 927 see linkgit:git-commit-tree[1] 928 929Git Diffs 930~~~~~~~~~ 931`GIT_DIFF_OPTS`:: 932 Only valid setting is "--unified=??" or "-u??" to set the 933 number of context lines shown when a unified diff is created. 934 This takes precedence over any "-U" or "--unified" option 935 value passed on the Git diff command line. 936 937`GIT_EXTERNAL_DIFF`:: 938 When the environment variable `GIT_EXTERNAL_DIFF` is set, the 939 program named by it is called, instead of the diff invocation 940 described above. For a path that is added, removed, or modified, 941 `GIT_EXTERNAL_DIFF` is called with 7 parameters: 942 943 path old-file old-hex old-mode new-file new-hex new-mode 944+ 945where: 946 947 <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the 948 contents of <old|new>, 949 <old|new>-hex:: are the 40-hexdigit SHA-1 hashes, 950 <old|new>-mode:: are the octal representation of the file modes. 951+ 952The file parameters can point at the user's working file 953(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file` 954when a new file is added), or a temporary file (e.g. `old-file` in the 955index). `GIT_EXTERNAL_DIFF` should not worry about unlinking the 956temporary file --- it is removed when `GIT_EXTERNAL_DIFF` exits. 957+ 958For a path that is unmerged, `GIT_EXTERNAL_DIFF` is called with 1 959parameter, <path>. 960+ 961For each path `GIT_EXTERNAL_DIFF` is called, two environment variables, 962`GIT_DIFF_PATH_COUNTER` and `GIT_DIFF_PATH_TOTAL` are set. 963 964`GIT_DIFF_PATH_COUNTER`:: 965 A 1-based counter incremented by one for every path. 966 967`GIT_DIFF_PATH_TOTAL`:: 968 The total number of paths. 969 970other 971~~~~~ 972`GIT_MERGE_VERBOSITY`:: 973 A number controlling the amount of output shown by 974 the recursive merge strategy. Overrides merge.verbosity. 975 See linkgit:git-merge[1] 976 977`GIT_PAGER`:: 978 This environment variable overrides `$PAGER`. If it is set 979 to an empty string or to the value "cat", Git will not launch 980 a pager. See also the `core.pager` option in 981 linkgit:git-config[1]. 982 983`GIT_EDITOR`:: 984 This environment variable overrides `$EDITOR` and `$VISUAL`. 985 It is used by several Git commands when, on interactive mode, 986 an editor is to be launched. See also linkgit:git-var[1] 987 and the `core.editor` option in linkgit:git-config[1]. 988 989`GIT_SSH`:: 990`GIT_SSH_COMMAND`:: 991 If either of these environment variables is set then 'git fetch' 992 and 'git push' will use the specified command instead of 'ssh' 993 when they need to connect to a remote system. 994 The command will be given exactly two or four arguments: the 995 'username@host' (or just 'host') from the URL and the shell 996 command to execute on that remote system, optionally preceded by 997 `-p` (literally) and the 'port' from the URL when it specifies 998 something other than the default SSH port. 999+1000`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted1001by the shell, which allows additional arguments to be included.1002`$GIT_SSH` on the other hand must be just the path to a program1003(which can be a wrapper shell script, if additional arguments are1004needed).1005+1006Usually it is easier to configure any desired options through your1007personal `.ssh/config` file. Please consult your ssh documentation1008for further details.10091010`GIT_ASKPASS`::1011 If this environment variable is set, then Git commands which need to1012 acquire passwords or passphrases (e.g. for HTTP or IMAP authentication)1013 will call this program with a suitable prompt as command-line argument1014 and read the password from its STDOUT. See also the `core.askPass`1015 option in linkgit:git-config[1].10161017`GIT_TERMINAL_PROMPT`::1018 If this environment variable is set to `0`, git will not prompt1019 on the terminal (e.g., when asking for HTTP authentication).10201021`GIT_CONFIG_NOSYSTEM`::1022 Whether to skip reading settings from the system-wide1023 `$(prefix)/etc/gitconfig` file. This environment variable can1024 be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a1025 predictable environment for a picky script, or you can set it1026 temporarily to avoid using a buggy `/etc/gitconfig` file while1027 waiting for someone with sufficient permissions to fix it.10281029`GIT_FLUSH`::1030 If this environment variable is set to "1", then commands such1031 as 'git blame' (in incremental mode), 'git rev-list', 'git log',1032 'git check-attr' and 'git check-ignore' will1033 force a flush of the output stream after each record have been1034 flushed. If this1035 variable is set to "0", the output of these commands will be done1036 using completely buffered I/O. If this environment variable is1037 not set, Git will choose buffered or record-oriented flushing1038 based on whether stdout appears to be redirected to a file or not.10391040`GIT_TRACE`::1041 Enables general trace messages, e.g. alias expansion, built-in1042 command execution and external command execution.1043+1044If this variable is set to "1", "2" or "true" (comparison1045is case insensitive), trace messages will be printed to1046stderr.1047+1048If the variable is set to an integer value greater than 21049and lower than 10 (strictly) then Git will interpret this1050value as an open file descriptor and will try to write the1051trace messages into this file descriptor.1052+1053Alternatively, if the variable is set to an absolute path1054(starting with a '/' character), Git will interpret this1055as a file path and will try to write the trace messages1056into it.1057+1058Unsetting the variable, or setting it to empty, "0" or1059"false" (case insensitive) disables trace messages.10601061`GIT_TRACE_PACK_ACCESS`::1062 Enables trace messages for all accesses to any packs. For each1063 access, the pack file name and an offset in the pack is1064 recorded. This may be helpful for troubleshooting some1065 pack-related performance problems.1066 See `GIT_TRACE` for available trace output options.10671068`GIT_TRACE_PACKET`::1069 Enables trace messages for all packets coming in or out of a1070 given program. This can help with debugging object negotiation1071 or other protocol issues. Tracing is turned off at a packet1072 starting with "PACK" (but see `GIT_TRACE_PACKFILE` below).1073 See `GIT_TRACE` for available trace output options.10741075`GIT_TRACE_PACKFILE`::1076 Enables tracing of packfiles sent or received by a1077 given program. Unlike other trace output, this trace is1078 verbatim: no headers, and no quoting of binary data. You almost1079 certainly want to direct into a file (e.g.,1080 `GIT_TRACE_PACKFILE=/tmp/my.pack`) rather than displaying it on1081 the terminal or mixing it with other trace output.1082+1083Note that this is currently only implemented for the client side1084of clones and fetches.10851086`GIT_TRACE_PERFORMANCE`::1087 Enables performance related trace messages, e.g. total execution1088 time of each Git command.1089 See `GIT_TRACE` for available trace output options.10901091`GIT_TRACE_SETUP`::1092 Enables trace messages printing the .git, working tree and current1093 working directory after Git has completed its setup phase.1094 See `GIT_TRACE` for available trace output options.10951096`GIT_TRACE_SHALLOW`::1097 Enables trace messages that can help debugging fetching /1098 cloning of shallow repositories.1099 See `GIT_TRACE` for available trace output options.11001101`GIT_TRACE_CURL`::1102 Enables a curl full trace dump of all incoming and outgoing data,1103 including descriptive information, of the git transport protocol.1104 This is similar to doing curl `--trace-ascii` on the command line.1105 This option overrides setting the `GIT_CURL_VERBOSE` environment1106 variable.1107 See `GIT_TRACE` for available trace output options.11081109`GIT_LITERAL_PATHSPECS`::1110 Setting this variable to `1` will cause Git to treat all1111 pathspecs literally, rather than as glob patterns. For example,1112 running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search1113 for commits that touch the path `*.c`, not any paths that the1114 glob `*.c` matches. You might want this if you are feeding1115 literal paths to Git (e.g., paths previously given to you by1116 `git ls-tree`, `--raw` diff output, etc).11171118`GIT_GLOB_PATHSPECS`::1119 Setting this variable to `1` will cause Git to treat all1120 pathspecs as glob patterns (aka "glob" magic).11211122`GIT_NOGLOB_PATHSPECS`::1123 Setting this variable to `1` will cause Git to treat all1124 pathspecs as literal (aka "literal" magic).11251126`GIT_ICASE_PATHSPECS`::1127 Setting this variable to `1` will cause Git to treat all1128 pathspecs as case-insensitive.11291130`GIT_REFLOG_ACTION`::1131 When a ref is updated, reflog entries are created to keep1132 track of the reason why the ref was updated (which is1133 typically the name of the high-level command that updated1134 the ref), in addition to the old and new values of the ref.1135 A scripted Porcelain command can use set_reflog_action1136 helper function in `git-sh-setup` to set its name to this1137 variable when it is invoked as the top level command by the1138 end user, to be recorded in the body of the reflog.11391140`GIT_REF_PARANOIA`::1141 If set to `1`, include broken or badly named refs when iterating1142 over lists of refs. In a normal, non-corrupted repository, this1143 does nothing. However, enabling it may help git to detect and1144 abort some operations in the presence of broken refs. Git sets1145 this variable automatically when performing destructive1146 operations like linkgit:git-prune[1]. You should not need to set1147 it yourself unless you want to be paranoid about making sure1148 an operation has touched every ref (e.g., because you are1149 cloning a repository to make a backup).11501151`GIT_ALLOW_PROTOCOL`::1152 If set, provide a colon-separated list of protocols which are1153 allowed to be used with fetch/push/clone. This is useful to1154 restrict recursive submodule initialization from an untrusted1155 repository. Any protocol not mentioned will be disallowed (i.e.,1156 this is a whitelist, not a blacklist). If the variable is not1157 set at all, all protocols are enabled. The protocol names1158 currently used by git are:11591160 - `file`: any local file-based path (including `file://` URLs,1161 or local paths)11621163 - `git`: the anonymous git protocol over a direct TCP1164 connection (or proxy, if configured)11651166 - `ssh`: git over ssh (including `host:path` syntax,1167 `ssh://`, etc).11681169 - `http`: git over http, both "smart http" and "dumb http".1170 Note that this does _not_ include `https`; if you want both,1171 you should specify both as `http:https`.11721173 - any external helpers are named by their protocol (e.g., use1174 `hg` to allow the `git-remote-hg` helper)117511761177Discussion[[Discussion]]1178------------------------11791180More detail on the following is available from the1181link:user-manual.html#git-concepts[Git concepts chapter of the1182user-manual] and linkgit:gitcore-tutorial[7].11831184A Git project normally consists of a working directory with a ".git"1185subdirectory at the top level. The .git directory contains, among other1186things, a compressed object database representing the complete history1187of the project, an "index" file which links that history to the current1188contents of the working tree, and named pointers into that history such1189as tags and branch heads.11901191The object database contains objects of three main types: blobs, which1192hold file data; trees, which point to blobs and other trees to build up1193directory hierarchies; and commits, which each reference a single tree1194and some number of parent commits.11951196The commit, equivalent to what other systems call a "changeset" or1197"version", represents a step in the project's history, and each parent1198represents an immediately preceding step. Commits with more than one1199parent represent merges of independent lines of development.12001201All objects are named by the SHA-1 hash of their contents, normally1202written as a string of 40 hex digits. Such names are globally unique.1203The entire history leading up to a commit can be vouched for by signing1204just that commit. A fourth object type, the tag, is provided for this1205purpose.12061207When first created, objects are stored in individual files, but for1208efficiency may later be compressed together into "pack files".12091210Named pointers called refs mark interesting points in history. A ref1211may contain the SHA-1 name of an object or the name of another ref. Refs1212with names beginning `ref/head/` contain the SHA-1 name of the most1213recent commit (or "head") of a branch under development. SHA-1 names of1214tags of interest are stored under `ref/tags/`. A special ref named1215`HEAD` contains the name of the currently checked-out branch.12161217The index file is initialized with a list of all paths and, for each1218path, a blob object and a set of attributes. The blob object represents1219the contents of the file as of the head of the current branch. The1220attributes (last modified time, size, etc.) are taken from the1221corresponding file in the working tree. Subsequent changes to the1222working tree can be found by comparing these attributes. The index may1223be updated with new content, and new commits may be created from the1224content stored in the index.12251226The index is also capable of storing multiple entries (called "stages")1227for a given pathname. These stages are used to hold the various1228unmerged version of a file when a merge is in progress.12291230FURTHER DOCUMENTATION1231---------------------12321233See the references in the "description" section to get started1234using Git.
