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. 504 505--help:: 506 Prints the synopsis and a list of the most commonly used 507 commands. If the option '--all' or '-a' is given then all 508 available commands are printed. If a Git command is named this 509 option will bring up the manual page for that command. 510+ 511Other options are available to control how the manual page is 512displayed. See linkgit:git-help[1] for more information, 513because `git --help ...` is converted internally into `git 514help ...`. 515 516-C <path>:: 517 Run as if git was started in '<path>' instead of the current working 518 directory. When multiple `-C` options are given, each subsequent 519 non-absolute `-C <path>` is interpreted relative to the preceding `-C 520 <path>`. 521+ 522This option affects options that expect path name like `--git-dir` and 523`--work-tree` in that their interpretations of the path names would be 524made relative to the working directory caused by the `-C` option. For 525example the following invocations are equivalent: 526 527 git --git-dir=a.git --work-tree=b -C c status 528 git --git-dir=c/a.git --work-tree=c/b status 529 530-c <name>=<value>:: 531 Pass a configuration parameter to the command. The value 532 given will override values from configuration files. 533 The <name> is expected in the same format as listed by 534 'git config' (subkeys separated by dots). 535+ 536Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets 537`foo.bar` to the boolean true value (just like `[foo]bar` would in a 538config file). Including the equals but with an empty value (like `git -c 539foo.bar= ...`) sets `foo.bar` to the empty string. 540 541--exec-path[=<path>]:: 542 Path to wherever your core Git programs are installed. 543 This can also be controlled by setting the GIT_EXEC_PATH 544 environment variable. If no path is given, 'git' will print 545 the current setting and then exit. 546 547--html-path:: 548 Print the path, without trailing slash, where Git's HTML 549 documentation is installed and exit. 550 551--man-path:: 552 Print the manpath (see `man(1)`) for the man pages for 553 this version of Git and exit. 554 555--info-path:: 556 Print the path where the Info files documenting this 557 version of Git are installed and exit. 558 559-p:: 560--paginate:: 561 Pipe all output into 'less' (or if set, $PAGER) if standard 562 output is a terminal. This overrides the `pager.<cmd>` 563 configuration options (see the "Configuration Mechanism" section 564 below). 565 566--no-pager:: 567 Do not pipe Git output into a pager. 568 569--git-dir=<path>:: 570 Set the path to the repository. This can also be controlled by 571 setting the GIT_DIR environment variable. It can be an absolute 572 path or relative path to current working directory. 573 574--work-tree=<path>:: 575 Set the path to the working tree. It can be an absolute path 576 or a path relative to the current working directory. 577 This can also be controlled by setting the GIT_WORK_TREE 578 environment variable and the core.worktree configuration 579 variable (see core.worktree in linkgit:git-config[1] for a 580 more detailed discussion). 581 582--namespace=<path>:: 583 Set the Git namespace. See linkgit:gitnamespaces[7] for more 584 details. Equivalent to setting the `GIT_NAMESPACE` environment 585 variable. 586 587--bare:: 588 Treat the repository as a bare repository. If GIT_DIR 589 environment is not set, it is set to the current working 590 directory. 591 592--no-replace-objects:: 593 Do not use replacement refs to replace Git objects. See 594 linkgit:git-replace[1] for more information. 595 596--literal-pathspecs:: 597 Treat pathspecs literally (i.e. no globbing, no pathspec magic). 598 This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment 599 variable to `1`. 600 601--glob-pathspecs:: 602 Add "glob" magic to all pathspec. This is equivalent to setting 603 the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling 604 globbing on individual pathspecs can be done using pathspec 605 magic ":(literal)" 606 607--noglob-pathspecs:: 608 Add "literal" magic to all pathspec. This is equivalent to setting 609 the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling 610 globbing on individual pathspecs can be done using pathspec 611 magic ":(glob)" 612 613--icase-pathspecs:: 614 Add "icase" magic to all pathspec. This is equivalent to setting 615 the `GIT_ICASE_PATHSPECS` environment variable to `1`. 616 617GIT COMMANDS 618------------ 619 620We divide Git into high level ("porcelain") commands and low level 621("plumbing") commands. 622 623High-level commands (porcelain) 624------------------------------- 625 626We separate the porcelain commands into the main commands and some 627ancillary user utilities. 628 629Main porcelain commands 630~~~~~~~~~~~~~~~~~~~~~~~ 631 632include::cmds-mainporcelain.txt[] 633 634Ancillary Commands 635~~~~~~~~~~~~~~~~~~ 636Manipulators: 637 638include::cmds-ancillarymanipulators.txt[] 639 640Interrogators: 641 642include::cmds-ancillaryinterrogators.txt[] 643 644 645Interacting with Others 646~~~~~~~~~~~~~~~~~~~~~~~ 647 648These commands are to interact with foreign SCM and with other 649people via patch over e-mail. 650 651include::cmds-foreignscminterface.txt[] 652 653 654Low-level commands (plumbing) 655----------------------------- 656 657Although Git includes its 658own porcelain layer, its low-level commands are sufficient to support 659development of alternative porcelains. Developers of such porcelains 660might start by reading about linkgit:git-update-index[1] and 661linkgit:git-read-tree[1]. 662 663The interface (input, output, set of options and the semantics) 664to these low-level commands are meant to be a lot more stable 665than Porcelain level commands, because these commands are 666primarily for scripted use. The interface to Porcelain commands 667on the other hand are subject to change in order to improve the 668end user experience. 669 670The following description divides 671the low-level commands into commands that manipulate objects (in 672the repository, index, and working tree), commands that interrogate and 673compare objects, and commands that move objects and references between 674repositories. 675 676 677Manipulation commands 678~~~~~~~~~~~~~~~~~~~~~ 679 680include::cmds-plumbingmanipulators.txt[] 681 682 683Interrogation commands 684~~~~~~~~~~~~~~~~~~~~~~ 685 686include::cmds-plumbinginterrogators.txt[] 687 688In general, the interrogate commands do not touch the files in 689the working tree. 690 691 692Synching repositories 693~~~~~~~~~~~~~~~~~~~~~ 694 695include::cmds-synchingrepositories.txt[] 696 697The following are helper commands used by the above; end users 698typically do not use them directly. 699 700include::cmds-synchelpers.txt[] 701 702 703Internal helper commands 704~~~~~~~~~~~~~~~~~~~~~~~~ 705 706These are internal helper commands used by other commands; end 707users typically do not use them directly. 708 709include::cmds-purehelpers.txt[] 710 711 712Configuration Mechanism 713----------------------- 714 715Git uses a simple text format to store customizations that are per 716repository and are per user. Such a configuration file may look 717like this: 718 719------------ 720# 721# A '#' or ';' character indicates a comment. 722# 723 724; core variables 725[core] 726 ; Don't trust file modes 727 filemode = false 728 729; user identity 730[user] 731 name = "Junio C Hamano" 732 email = "gitster@pobox.com" 733 734------------ 735 736Various commands read from the configuration file and adjust 737their operation accordingly. See linkgit:git-config[1] for a 738list and more details about the configuration mechanism. 739 740 741Identifier Terminology 742---------------------- 743<object>:: 744 Indicates the object name for any type of object. 745 746<blob>:: 747 Indicates a blob object name. 748 749<tree>:: 750 Indicates a tree object name. 751 752<commit>:: 753 Indicates a commit object name. 754 755<tree-ish>:: 756 Indicates a tree, commit or tag object name. A 757 command that takes a <tree-ish> argument ultimately wants to 758 operate on a <tree> object but automatically dereferences 759 <commit> and <tag> objects that point at a <tree>. 760 761<commit-ish>:: 762 Indicates a commit or tag object name. A 763 command that takes a <commit-ish> argument ultimately wants to 764 operate on a <commit> object but automatically dereferences 765 <tag> objects that point at a <commit>. 766 767<type>:: 768 Indicates that an object type is required. 769 Currently one of: `blob`, `tree`, `commit`, or `tag`. 770 771<file>:: 772 Indicates a filename - almost always relative to the 773 root of the tree structure `GIT_INDEX_FILE` describes. 774 775Symbolic Identifiers 776-------------------- 777Any Git command accepting any <object> can also use the following 778symbolic notation: 779 780HEAD:: 781 indicates the head of the current branch. 782 783<tag>:: 784 a valid tag 'name' 785 (i.e. a `refs/tags/<tag>` reference). 786 787<head>:: 788 a valid head 'name' 789 (i.e. a `refs/heads/<head>` reference). 790 791For a more complete list of ways to spell object names, see 792"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7]. 793 794 795File/Directory Structure 796------------------------ 797 798Please see the linkgit:gitrepository-layout[5] document. 799 800Read linkgit:githooks[5] for more details about each hook. 801 802Higher level SCMs may provide and manage additional information in the 803`$GIT_DIR`. 804 805 806Terminology 807----------- 808Please see linkgit:gitglossary[7]. 809 810 811Environment Variables 812--------------------- 813Various Git commands use the following environment variables: 814 815The Git Repository 816~~~~~~~~~~~~~~~~~~ 817These environment variables apply to 'all' core Git commands. Nb: it 818is worth noting that they may be used/overridden by SCMS sitting above 819Git so take care if using a foreign front-end. 820 821'GIT_INDEX_FILE':: 822 This environment allows the specification of an alternate 823 index file. If not specified, the default of `$GIT_DIR/index` 824 is used. 825 826'GIT_INDEX_VERSION':: 827 This environment variable allows the specification of an index 828 version for new repositories. It won't affect existing index 829 files. By default index file version 2 or 3 is used. See 830 linkgit:git-update-index[1] for more information. 831 832'GIT_OBJECT_DIRECTORY':: 833 If the object storage directory is specified via this 834 environment variable then the sha1 directories are created 835 underneath - otherwise the default `$GIT_DIR/objects` 836 directory is used. 837 838'GIT_ALTERNATE_OBJECT_DIRECTORIES':: 839 Due to the immutable nature of Git objects, old objects can be 840 archived into shared, read-only directories. This variable 841 specifies a ":" separated (on Windows ";" separated) list 842 of Git object directories which can be used to search for Git 843 objects. New objects will not be written to these directories. 844 845'GIT_DIR':: 846 If the 'GIT_DIR' environment variable is set then it 847 specifies a path to use instead of the default `.git` 848 for the base of the repository. 849 The '--git-dir' command-line option also sets this value. 850 851'GIT_WORK_TREE':: 852 Set the path to the root of the working tree. 853 This can also be controlled by the '--work-tree' command-line 854 option and the core.worktree configuration variable. 855 856'GIT_NAMESPACE':: 857 Set the Git namespace; see linkgit:gitnamespaces[7] for details. 858 The '--namespace' command-line option also sets this value. 859 860'GIT_CEILING_DIRECTORIES':: 861 This should be a colon-separated list of absolute paths. If 862 set, it is a list of directories that Git should not chdir up 863 into while looking for a repository directory (useful for 864 excluding slow-loading network directories). It will not 865 exclude the current working directory or a GIT_DIR set on the 866 command line or in the environment. Normally, Git has to read 867 the entries in this list and resolve any symlink that 868 might be present in order to compare them with the current 869 directory. However, if even this access is slow, you 870 can add an empty entry to the list to tell Git that the 871 subsequent entries are not symlinks and needn't be resolved; 872 e.g., 873 'GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink'. 874 875'GIT_DISCOVERY_ACROSS_FILESYSTEM':: 876 When run in a directory that does not have ".git" repository 877 directory, Git tries to find such a directory in the parent 878 directories to find the top of the working tree, but by default it 879 does not cross filesystem boundaries. This environment variable 880 can be set to true to tell Git not to stop at filesystem 881 boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect 882 an explicit repository directory set via 'GIT_DIR' or on the 883 command line. 884 885'GIT_COMMON_DIR':: 886 If this variable is set to a path, non-worktree files that are 887 normally in $GIT_DIR will be taken from this path 888 instead. Worktree-specific files such as HEAD or index are 889 taken from $GIT_DIR. See linkgit:gitrepository-layout[5] and 890 linkgit:git-worktree[1] for 891 details. This variable has lower precedence than other path 892 variables such as GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY... 893 894Git Commits 895~~~~~~~~~~~ 896'GIT_AUTHOR_NAME':: 897'GIT_AUTHOR_EMAIL':: 898'GIT_AUTHOR_DATE':: 899'GIT_COMMITTER_NAME':: 900'GIT_COMMITTER_EMAIL':: 901'GIT_COMMITTER_DATE':: 902'EMAIL':: 903 see linkgit:git-commit-tree[1] 904 905Git Diffs 906~~~~~~~~~ 907'GIT_DIFF_OPTS':: 908 Only valid setting is "--unified=??" or "-u??" to set the 909 number of context lines shown when a unified diff is created. 910 This takes precedence over any "-U" or "--unified" option 911 value passed on the Git diff command line. 912 913'GIT_EXTERNAL_DIFF':: 914 When the environment variable 'GIT_EXTERNAL_DIFF' is set, the 915 program named by it is called, instead of the diff invocation 916 described above. For a path that is added, removed, or modified, 917 'GIT_EXTERNAL_DIFF' is called with 7 parameters: 918 919 path old-file old-hex old-mode new-file new-hex new-mode 920+ 921where: 922 923 <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the 924 contents of <old|new>, 925 <old|new>-hex:: are the 40-hexdigit SHA-1 hashes, 926 <old|new>-mode:: are the octal representation of the file modes. 927+ 928The file parameters can point at the user's working file 929(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file` 930when a new file is added), or a temporary file (e.g. `old-file` in the 931index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the 932temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits. 933+ 934For a path that is unmerged, 'GIT_EXTERNAL_DIFF' is called with 1 935parameter, <path>. 936+ 937For each path 'GIT_EXTERNAL_DIFF' is called, two environment variables, 938'GIT_DIFF_PATH_COUNTER' and 'GIT_DIFF_PATH_TOTAL' are set. 939 940'GIT_DIFF_PATH_COUNTER':: 941 A 1-based counter incremented by one for every path. 942 943'GIT_DIFF_PATH_TOTAL':: 944 The total number of paths. 945 946other 947~~~~~ 948'GIT_MERGE_VERBOSITY':: 949 A number controlling the amount of output shown by 950 the recursive merge strategy. Overrides merge.verbosity. 951 See linkgit:git-merge[1] 952 953'GIT_PAGER':: 954 This environment variable overrides `$PAGER`. If it is set 955 to an empty string or to the value "cat", Git will not launch 956 a pager. See also the `core.pager` option in 957 linkgit:git-config[1]. 958 959'GIT_EDITOR':: 960 This environment variable overrides `$EDITOR` and `$VISUAL`. 961 It is used by several Git commands when, on interactive mode, 962 an editor is to be launched. See also linkgit:git-var[1] 963 and the `core.editor` option in linkgit:git-config[1]. 964 965'GIT_SSH':: 966'GIT_SSH_COMMAND':: 967 If either of these environment variables is set then 'git fetch' 968 and 'git push' will use the specified command instead of 'ssh' 969 when they need to connect to a remote system. 970 The command will be given exactly two or four arguments: the 971 'username@host' (or just 'host') from the URL and the shell 972 command to execute on that remote system, optionally preceded by 973 '-p' (literally) and the 'port' from the URL when it specifies 974 something other than the default SSH port. 975+ 976`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted 977by the shell, which allows additional arguments to be included. 978`$GIT_SSH` on the other hand must be just the path to a program 979(which can be a wrapper shell script, if additional arguments are 980needed). 981+ 982Usually it is easier to configure any desired options through your 983personal `.ssh/config` file. Please consult your ssh documentation 984for further details. 985 986'GIT_ASKPASS':: 987 If this environment variable is set, then Git commands which need to 988 acquire passwords or passphrases (e.g. for HTTP or IMAP authentication) 989 will call this program with a suitable prompt as command-line argument 990 and read the password from its STDOUT. See also the 'core.askPass' 991 option in linkgit:git-config[1]. 992 993'GIT_TERMINAL_PROMPT':: 994 If this environment variable is set to `0`, git will not prompt 995 on the terminal (e.g., when asking for HTTP authentication). 996 997'GIT_CONFIG_NOSYSTEM':: 998 Whether to skip reading settings from the system-wide 999 `$(prefix)/etc/gitconfig` file. This environment variable can1000 be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a1001 predictable environment for a picky script, or you can set it1002 temporarily to avoid using a buggy `/etc/gitconfig` file while1003 waiting for someone with sufficient permissions to fix it.10041005'GIT_FLUSH'::1006 If this environment variable is set to "1", then commands such1007 as 'git blame' (in incremental mode), 'git rev-list', 'git log',1008 'git check-attr' and 'git check-ignore' will1009 force a flush of the output stream after each record have been1010 flushed. If this1011 variable is set to "0", the output of these commands will be done1012 using completely buffered I/O. If this environment variable is1013 not set, Git will choose buffered or record-oriented flushing1014 based on whether stdout appears to be redirected to a file or not.10151016'GIT_TRACE'::1017 Enables general trace messages, e.g. alias expansion, built-in1018 command execution and external command execution.1019+1020If this variable is set to "1", "2" or "true" (comparison1021is case insensitive), trace messages will be printed to1022stderr.1023+1024If the variable is set to an integer value greater than 21025and lower than 10 (strictly) then Git will interpret this1026value as an open file descriptor and will try to write the1027trace messages into this file descriptor.1028+1029Alternatively, if the variable is set to an absolute path1030(starting with a '/' character), Git will interpret this1031as a file path and will try to write the trace messages1032into it.1033+1034Unsetting the variable, or setting it to empty, "0" or1035"false" (case insensitive) disables trace messages.10361037'GIT_TRACE_PACK_ACCESS'::1038 Enables trace messages for all accesses to any packs. For each1039 access, the pack file name and an offset in the pack is1040 recorded. This may be helpful for troubleshooting some1041 pack-related performance problems.1042 See 'GIT_TRACE' for available trace output options.10431044'GIT_TRACE_PACKET'::1045 Enables trace messages for all packets coming in or out of a1046 given program. This can help with debugging object negotiation1047 or other protocol issues. Tracing is turned off at a packet1048 starting with "PACK" (but see 'GIT_TRACE_PACKFILE' below).1049 See 'GIT_TRACE' for available trace output options.10501051'GIT_TRACE_PACKFILE'::1052 Enables tracing of packfiles sent or received by a1053 given program. Unlike other trace output, this trace is1054 verbatim: no headers, and no quoting of binary data. You almost1055 certainly want to direct into a file (e.g.,1056 `GIT_TRACE_PACKFILE=/tmp/my.pack`) rather than displaying it on1057 the terminal or mixing it with other trace output.1058+1059Note that this is currently only implemented for the client side1060of clones and fetches.10611062'GIT_TRACE_PERFORMANCE'::1063 Enables performance related trace messages, e.g. total execution1064 time of each Git command.1065 See 'GIT_TRACE' for available trace output options.10661067'GIT_TRACE_SETUP'::1068 Enables trace messages printing the .git, working tree and current1069 working directory after Git has completed its setup phase.1070 See 'GIT_TRACE' for available trace output options.10711072'GIT_TRACE_SHALLOW'::1073 Enables trace messages that can help debugging fetching /1074 cloning of shallow repositories.1075 See 'GIT_TRACE' for available trace output options.10761077'GIT_LITERAL_PATHSPECS'::1078 Setting this variable to `1` will cause Git to treat all1079 pathspecs literally, rather than as glob patterns. For example,1080 running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search1081 for commits that touch the path `*.c`, not any paths that the1082 glob `*.c` matches. You might want this if you are feeding1083 literal paths to Git (e.g., paths previously given to you by1084 `git ls-tree`, `--raw` diff output, etc).10851086'GIT_GLOB_PATHSPECS'::1087 Setting this variable to `1` will cause Git to treat all1088 pathspecs as glob patterns (aka "glob" magic).10891090'GIT_NOGLOB_PATHSPECS'::1091 Setting this variable to `1` will cause Git to treat all1092 pathspecs as literal (aka "literal" magic).10931094'GIT_ICASE_PATHSPECS'::1095 Setting this variable to `1` will cause Git to treat all1096 pathspecs as case-insensitive.10971098'GIT_REFLOG_ACTION'::1099 When a ref is updated, reflog entries are created to keep1100 track of the reason why the ref was updated (which is1101 typically the name of the high-level command that updated1102 the ref), in addition to the old and new values of the ref.1103 A scripted Porcelain command can use set_reflog_action1104 helper function in `git-sh-setup` to set its name to this1105 variable when it is invoked as the top level command by the1106 end user, to be recorded in the body of the reflog.11071108'GIT_REF_PARANOIA'::1109 If set to `1`, include broken or badly named refs when iterating1110 over lists of refs. In a normal, non-corrupted repository, this1111 does nothing. However, enabling it may help git to detect and1112 abort some operations in the presence of broken refs. Git sets1113 this variable automatically when performing destructive1114 operations like linkgit:git-prune[1]. You should not need to set1115 it yourself unless you want to be paranoid about making sure1116 an operation has touched every ref (e.g., because you are1117 cloning a repository to make a backup).11181119'GIT_ALLOW_PROTOCOL'::1120 If set, provide a colon-separated list of protocols which are1121 allowed to be used with fetch/push/clone. This is useful to1122 restrict recursive submodule initialization from an untrusted1123 repository. Any protocol not mentioned will be disallowed (i.e.,1124 this is a whitelist, not a blacklist). If the variable is not1125 set at all, all protocols are enabled. The protocol names1126 currently used by git are:11271128 - `file`: any local file-based path (including `file://` URLs,1129 or local paths)11301131 - `git`: the anonymous git protocol over a direct TCP1132 connection (or proxy, if configured)11331134 - `ssh`: git over ssh (including `host:path` syntax,1135 `ssh://`, etc).11361137 - `http`: git over http, both "smart http" and "dumb http".1138 Note that this does _not_ include `https`; if you want both,1139 you should specify both as `http:https`.11401141 - any external helpers are named by their protocol (e.g., use1142 `hg` to allow the `git-remote-hg` helper)114311441145Discussion[[Discussion]]1146------------------------11471148More detail on the following is available from the1149link:user-manual.html#git-concepts[Git concepts chapter of the1150user-manual] and linkgit:gitcore-tutorial[7].11511152A Git project normally consists of a working directory with a ".git"1153subdirectory at the top level. The .git directory contains, among other1154things, a compressed object database representing the complete history1155of the project, an "index" file which links that history to the current1156contents of the working tree, and named pointers into that history such1157as tags and branch heads.11581159The object database contains objects of three main types: blobs, which1160hold file data; trees, which point to blobs and other trees to build up1161directory hierarchies; and commits, which each reference a single tree1162and some number of parent commits.11631164The commit, equivalent to what other systems call a "changeset" or1165"version", represents a step in the project's history, and each parent1166represents an immediately preceding step. Commits with more than one1167parent represent merges of independent lines of development.11681169All objects are named by the SHA-1 hash of their contents, normally1170written as a string of 40 hex digits. Such names are globally unique.1171The entire history leading up to a commit can be vouched for by signing1172just that commit. A fourth object type, the tag, is provided for this1173purpose.11741175When first created, objects are stored in individual files, but for1176efficiency may later be compressed together into "pack files".11771178Named pointers called refs mark interesting points in history. A ref1179may contain the SHA-1 name of an object or the name of another ref. Refs1180with names beginning `ref/head/` contain the SHA-1 name of the most1181recent commit (or "head") of a branch under development. SHA-1 names of1182tags of interest are stored under `ref/tags/`. A special ref named1183`HEAD` contains the name of the currently checked-out branch.11841185The index file is initialized with a list of all paths and, for each1186path, a blob object and a set of attributes. The blob object represents1187the contents of the file as of the head of the current branch. The1188attributes (last modified time, size, etc.) are taken from the1189corresponding file in the working tree. Subsequent changes to the1190working tree can be found by comparing these attributes. The index may1191be updated with new content, and new commits may be created from the1192content stored in the index.11931194The index is also capable of storing multiple entries (called "stages")1195for a given pathname. These stages are used to hold the various1196unmerged version of a file when a merge is in progress.11971198FURTHER DOCUMENTATION1199---------------------12001201See the references in the "description" section to get started1202using Git.
