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. 505 506--help:: 507 Prints the synopsis and a list of the most commonly used 508 commands. If the option '--all' or '-a' is given then all 509 available commands are printed. If a Git command is named this 510 option will bring up the manual page for that command. 511+ 512Other options are available to control how the manual page is 513displayed. See linkgit:git-help[1] for more information, 514because `git --help ...` is converted internally into `git 515help ...`. 516 517-C <path>:: 518 Run as if git was started in '<path>' instead of the current working 519 directory. When multiple `-C` options are given, each subsequent 520 non-absolute `-C <path>` is interpreted relative to the preceding `-C 521 <path>`. 522+ 523This option affects options that expect path name like `--git-dir` and 524`--work-tree` in that their interpretations of the path names would be 525made relative to the working directory caused by the `-C` option. For 526example the following invocations are equivalent: 527 528 git --git-dir=a.git --work-tree=b -C c status 529 git --git-dir=c/a.git --work-tree=c/b status 530 531-c <name>=<value>:: 532 Pass a configuration parameter to the command. The value 533 given will override values from configuration files. 534 The <name> is expected in the same format as listed by 535 'git config' (subkeys separated by dots). 536+ 537Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets 538`foo.bar` to the boolean true value (just like `[foo]bar` would in a 539config file). Including the equals but with an empty value (like `git -c 540foo.bar= ...`) sets `foo.bar` to the empty string. 541 542--exec-path[=<path>]:: 543 Path to wherever your core Git programs are installed. 544 This can also be controlled by setting the GIT_EXEC_PATH 545 environment variable. If no path is given, 'git' will print 546 the current setting and then exit. 547 548--html-path:: 549 Print the path, without trailing slash, where Git's HTML 550 documentation is installed and exit. 551 552--man-path:: 553 Print the manpath (see `man(1)`) for the man pages for 554 this version of Git and exit. 555 556--info-path:: 557 Print the path where the Info files documenting this 558 version of Git are installed and exit. 559 560-p:: 561--paginate:: 562 Pipe all output into 'less' (or if set, $PAGER) if standard 563 output is a terminal. This overrides the `pager.<cmd>` 564 configuration options (see the "Configuration Mechanism" section 565 below). 566 567--no-pager:: 568 Do not pipe Git output into a pager. 569 570--git-dir=<path>:: 571 Set the path to the repository. This can also be controlled by 572 setting the GIT_DIR environment variable. It can be an absolute 573 path or relative path to current working directory. 574 575--work-tree=<path>:: 576 Set the path to the working tree. It can be an absolute path 577 or a path relative to the current working directory. 578 This can also be controlled by setting the GIT_WORK_TREE 579 environment variable and the core.worktree configuration 580 variable (see core.worktree in linkgit:git-config[1] for a 581 more detailed discussion). 582 583--namespace=<path>:: 584 Set the Git namespace. See linkgit:gitnamespaces[7] for more 585 details. Equivalent to setting the `GIT_NAMESPACE` environment 586 variable. 587 588--bare:: 589 Treat the repository as a bare repository. If GIT_DIR 590 environment is not set, it is set to the current working 591 directory. 592 593--no-replace-objects:: 594 Do not use replacement refs to replace Git objects. See 595 linkgit:git-replace[1] for more information. 596 597--literal-pathspecs:: 598 Treat pathspecs literally (i.e. no globbing, no pathspec magic). 599 This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment 600 variable to `1`. 601 602--glob-pathspecs:: 603 Add "glob" magic to all pathspec. This is equivalent to setting 604 the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling 605 globbing on individual pathspecs can be done using pathspec 606 magic ":(literal)" 607 608--noglob-pathspecs:: 609 Add "literal" magic to all pathspec. This is equivalent to setting 610 the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling 611 globbing on individual pathspecs can be done using pathspec 612 magic ":(glob)" 613 614--icase-pathspecs:: 615 Add "icase" magic to all pathspec. This is equivalent to setting 616 the `GIT_ICASE_PATHSPECS` environment variable to `1`. 617 618GIT COMMANDS 619------------ 620 621We divide Git into high level ("porcelain") commands and low level 622("plumbing") commands. 623 624High-level commands (porcelain) 625------------------------------- 626 627We separate the porcelain commands into the main commands and some 628ancillary user utilities. 629 630Main porcelain commands 631~~~~~~~~~~~~~~~~~~~~~~~ 632 633include::cmds-mainporcelain.txt[] 634 635Ancillary Commands 636~~~~~~~~~~~~~~~~~~ 637Manipulators: 638 639include::cmds-ancillarymanipulators.txt[] 640 641Interrogators: 642 643include::cmds-ancillaryinterrogators.txt[] 644 645 646Interacting with Others 647~~~~~~~~~~~~~~~~~~~~~~~ 648 649These commands are to interact with foreign SCM and with other 650people via patch over e-mail. 651 652include::cmds-foreignscminterface.txt[] 653 654 655Low-level commands (plumbing) 656----------------------------- 657 658Although Git includes its 659own porcelain layer, its low-level commands are sufficient to support 660development of alternative porcelains. Developers of such porcelains 661might start by reading about linkgit:git-update-index[1] and 662linkgit:git-read-tree[1]. 663 664The interface (input, output, set of options and the semantics) 665to these low-level commands are meant to be a lot more stable 666than Porcelain level commands, because these commands are 667primarily for scripted use. The interface to Porcelain commands 668on the other hand are subject to change in order to improve the 669end user experience. 670 671The following description divides 672the low-level commands into commands that manipulate objects (in 673the repository, index, and working tree), commands that interrogate and 674compare objects, and commands that move objects and references between 675repositories. 676 677 678Manipulation commands 679~~~~~~~~~~~~~~~~~~~~~ 680 681include::cmds-plumbingmanipulators.txt[] 682 683 684Interrogation commands 685~~~~~~~~~~~~~~~~~~~~~~ 686 687include::cmds-plumbinginterrogators.txt[] 688 689In general, the interrogate commands do not touch the files in 690the working tree. 691 692 693Synching repositories 694~~~~~~~~~~~~~~~~~~~~~ 695 696include::cmds-synchingrepositories.txt[] 697 698The following are helper commands used by the above; end users 699typically do not use them directly. 700 701include::cmds-synchelpers.txt[] 702 703 704Internal helper commands 705~~~~~~~~~~~~~~~~~~~~~~~~ 706 707These are internal helper commands used by other commands; end 708users typically do not use them directly. 709 710include::cmds-purehelpers.txt[] 711 712 713Configuration Mechanism 714----------------------- 715 716Git uses a simple text format to store customizations that are per 717repository and are per user. Such a configuration file may look 718like this: 719 720------------ 721# 722# A '#' or ';' character indicates a comment. 723# 724 725; core variables 726[core] 727 ; Don't trust file modes 728 filemode = false 729 730; user identity 731[user] 732 name = "Junio C Hamano" 733 email = "gitster@pobox.com" 734 735------------ 736 737Various commands read from the configuration file and adjust 738their operation accordingly. See linkgit:git-config[1] for a 739list and more details about the configuration mechanism. 740 741 742Identifier Terminology 743---------------------- 744<object>:: 745 Indicates the object name for any type of object. 746 747<blob>:: 748 Indicates a blob object name. 749 750<tree>:: 751 Indicates a tree object name. 752 753<commit>:: 754 Indicates a commit object name. 755 756<tree-ish>:: 757 Indicates a tree, commit or tag object name. A 758 command that takes a <tree-ish> argument ultimately wants to 759 operate on a <tree> object but automatically dereferences 760 <commit> and <tag> objects that point at a <tree>. 761 762<commit-ish>:: 763 Indicates a commit or tag object name. A 764 command that takes a <commit-ish> argument ultimately wants to 765 operate on a <commit> object but automatically dereferences 766 <tag> objects that point at a <commit>. 767 768<type>:: 769 Indicates that an object type is required. 770 Currently one of: `blob`, `tree`, `commit`, or `tag`. 771 772<file>:: 773 Indicates a filename - almost always relative to the 774 root of the tree structure `GIT_INDEX_FILE` describes. 775 776Symbolic Identifiers 777-------------------- 778Any Git command accepting any <object> can also use the following 779symbolic notation: 780 781HEAD:: 782 indicates the head of the current branch. 783 784<tag>:: 785 a valid tag 'name' 786 (i.e. a `refs/tags/<tag>` reference). 787 788<head>:: 789 a valid head 'name' 790 (i.e. a `refs/heads/<head>` reference). 791 792For a more complete list of ways to spell object names, see 793"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7]. 794 795 796File/Directory Structure 797------------------------ 798 799Please see the linkgit:gitrepository-layout[5] document. 800 801Read linkgit:githooks[5] for more details about each hook. 802 803Higher level SCMs may provide and manage additional information in the 804`$GIT_DIR`. 805 806 807Terminology 808----------- 809Please see linkgit:gitglossary[7]. 810 811 812Environment Variables 813--------------------- 814Various Git commands use the following environment variables: 815 816The Git Repository 817~~~~~~~~~~~~~~~~~~ 818These environment variables apply to 'all' core Git commands. Nb: it 819is worth noting that they may be used/overridden by SCMS sitting above 820Git so take care if using a foreign front-end. 821 822'GIT_INDEX_FILE':: 823 This environment allows the specification of an alternate 824 index file. If not specified, the default of `$GIT_DIR/index` 825 is used. 826 827'GIT_INDEX_VERSION':: 828 This environment variable allows the specification of an index 829 version for new repositories. It won't affect existing index 830 files. By default index file version 2 or 3 is used. See 831 linkgit:git-update-index[1] for more information. 832 833'GIT_OBJECT_DIRECTORY':: 834 If the object storage directory is specified via this 835 environment variable then the sha1 directories are created 836 underneath - otherwise the default `$GIT_DIR/objects` 837 directory is used. 838 839'GIT_ALTERNATE_OBJECT_DIRECTORIES':: 840 Due to the immutable nature of Git objects, old objects can be 841 archived into shared, read-only directories. This variable 842 specifies a ":" separated (on Windows ";" separated) list 843 of Git object directories which can be used to search for Git 844 objects. New objects will not be written to these directories. 845 846'GIT_DIR':: 847 If the 'GIT_DIR' environment variable is set then it 848 specifies a path to use instead of the default `.git` 849 for the base of the repository. 850 The '--git-dir' command-line option also sets this value. 851 852'GIT_WORK_TREE':: 853 Set the path to the root of the working tree. 854 This can also be controlled by the '--work-tree' command-line 855 option and the core.worktree configuration variable. 856 857'GIT_NAMESPACE':: 858 Set the Git namespace; see linkgit:gitnamespaces[7] for details. 859 The '--namespace' command-line option also sets this value. 860 861'GIT_CEILING_DIRECTORIES':: 862 This should be a colon-separated list of absolute paths. If 863 set, it is a list of directories that Git should not chdir up 864 into while looking for a repository directory (useful for 865 excluding slow-loading network directories). It will not 866 exclude the current working directory or a GIT_DIR set on the 867 command line or in the environment. Normally, Git has to read 868 the entries in this list and resolve any symlink that 869 might be present in order to compare them with the current 870 directory. However, if even this access is slow, you 871 can add an empty entry to the list to tell Git that the 872 subsequent entries are not symlinks and needn't be resolved; 873 e.g., 874 'GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink'. 875 876'GIT_DISCOVERY_ACROSS_FILESYSTEM':: 877 When run in a directory that does not have ".git" repository 878 directory, Git tries to find such a directory in the parent 879 directories to find the top of the working tree, but by default it 880 does not cross filesystem boundaries. This environment variable 881 can be set to true to tell Git not to stop at filesystem 882 boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect 883 an explicit repository directory set via 'GIT_DIR' or on the 884 command line. 885 886'GIT_COMMON_DIR':: 887 If this variable is set to a path, non-worktree files that are 888 normally in $GIT_DIR will be taken from this path 889 instead. Worktree-specific files such as HEAD or index are 890 taken from $GIT_DIR. See linkgit:gitrepository-layout[5] and 891 linkgit:git-worktree[1] for 892 details. This variable has lower precedence than other path 893 variables such as GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY... 894 895Git Commits 896~~~~~~~~~~~ 897'GIT_AUTHOR_NAME':: 898'GIT_AUTHOR_EMAIL':: 899'GIT_AUTHOR_DATE':: 900'GIT_COMMITTER_NAME':: 901'GIT_COMMITTER_EMAIL':: 902'GIT_COMMITTER_DATE':: 903'EMAIL':: 904 see linkgit:git-commit-tree[1] 905 906Git Diffs 907~~~~~~~~~ 908'GIT_DIFF_OPTS':: 909 Only valid setting is "--unified=??" or "-u??" to set the 910 number of context lines shown when a unified diff is created. 911 This takes precedence over any "-U" or "--unified" option 912 value passed on the Git diff command line. 913 914'GIT_EXTERNAL_DIFF':: 915 When the environment variable 'GIT_EXTERNAL_DIFF' is set, the 916 program named by it is called, instead of the diff invocation 917 described above. For a path that is added, removed, or modified, 918 'GIT_EXTERNAL_DIFF' is called with 7 parameters: 919 920 path old-file old-hex old-mode new-file new-hex new-mode 921+ 922where: 923 924 <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the 925 contents of <old|new>, 926 <old|new>-hex:: are the 40-hexdigit SHA-1 hashes, 927 <old|new>-mode:: are the octal representation of the file modes. 928+ 929The file parameters can point at the user's working file 930(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file` 931when a new file is added), or a temporary file (e.g. `old-file` in the 932index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the 933temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits. 934+ 935For a path that is unmerged, 'GIT_EXTERNAL_DIFF' is called with 1 936parameter, <path>. 937+ 938For each path 'GIT_EXTERNAL_DIFF' is called, two environment variables, 939'GIT_DIFF_PATH_COUNTER' and 'GIT_DIFF_PATH_TOTAL' are set. 940 941'GIT_DIFF_PATH_COUNTER':: 942 A 1-based counter incremented by one for every path. 943 944'GIT_DIFF_PATH_TOTAL':: 945 The total number of paths. 946 947other 948~~~~~ 949'GIT_MERGE_VERBOSITY':: 950 A number controlling the amount of output shown by 951 the recursive merge strategy. Overrides merge.verbosity. 952 See linkgit:git-merge[1] 953 954'GIT_PAGER':: 955 This environment variable overrides `$PAGER`. If it is set 956 to an empty string or to the value "cat", Git will not launch 957 a pager. See also the `core.pager` option in 958 linkgit:git-config[1]. 959 960'GIT_EDITOR':: 961 This environment variable overrides `$EDITOR` and `$VISUAL`. 962 It is used by several Git commands when, on interactive mode, 963 an editor is to be launched. See also linkgit:git-var[1] 964 and the `core.editor` option in linkgit:git-config[1]. 965 966'GIT_SSH':: 967'GIT_SSH_COMMAND':: 968 If either of these environment variables is set then 'git fetch' 969 and 'git push' will use the specified command instead of 'ssh' 970 when they need to connect to a remote system. 971 The command will be given exactly two or four arguments: the 972 'username@host' (or just 'host') from the URL and the shell 973 command to execute on that remote system, optionally preceded by 974 '-p' (literally) and the 'port' from the URL when it specifies 975 something other than the default SSH port. 976+ 977`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted 978by the shell, which allows additional arguments to be included. 979`$GIT_SSH` on the other hand must be just the path to a program 980(which can be a wrapper shell script, if additional arguments are 981needed). 982+ 983Usually it is easier to configure any desired options through your 984personal `.ssh/config` file. Please consult your ssh documentation 985for further details. 986 987'GIT_ASKPASS':: 988 If this environment variable is set, then Git commands which need to 989 acquire passwords or passphrases (e.g. for HTTP or IMAP authentication) 990 will call this program with a suitable prompt as command-line argument 991 and read the password from its STDOUT. See also the 'core.askPass' 992 option in linkgit:git-config[1]. 993 994'GIT_TERMINAL_PROMPT':: 995 If this environment variable is set to `0`, git will not prompt 996 on the terminal (e.g., when asking for HTTP authentication). 997 998'GIT_CONFIG_NOSYSTEM':: 999 Whether to skip reading settings from the system-wide1000 `$(prefix)/etc/gitconfig` file. This environment variable can1001 be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a1002 predictable environment for a picky script, or you can set it1003 temporarily to avoid using a buggy `/etc/gitconfig` file while1004 waiting for someone with sufficient permissions to fix it.10051006'GIT_FLUSH'::1007 If this environment variable is set to "1", then commands such1008 as 'git blame' (in incremental mode), 'git rev-list', 'git log',1009 'git check-attr' and 'git check-ignore' will1010 force a flush of the output stream after each record have been1011 flushed. If this1012 variable is set to "0", the output of these commands will be done1013 using completely buffered I/O. If this environment variable is1014 not set, Git will choose buffered or record-oriented flushing1015 based on whether stdout appears to be redirected to a file or not.10161017'GIT_TRACE'::1018 Enables general trace messages, e.g. alias expansion, built-in1019 command execution and external command execution.1020+1021If this variable is set to "1", "2" or "true" (comparison1022is case insensitive), trace messages will be printed to1023stderr.1024+1025If the variable is set to an integer value greater than 21026and lower than 10 (strictly) then Git will interpret this1027value as an open file descriptor and will try to write the1028trace messages into this file descriptor.1029+1030Alternatively, if the variable is set to an absolute path1031(starting with a '/' character), Git will interpret this1032as a file path and will try to write the trace messages1033into it.1034+1035Unsetting the variable, or setting it to empty, "0" or1036"false" (case insensitive) disables trace messages.10371038'GIT_TRACE_PACK_ACCESS'::1039 Enables trace messages for all accesses to any packs. For each1040 access, the pack file name and an offset in the pack is1041 recorded. This may be helpful for troubleshooting some1042 pack-related performance problems.1043 See 'GIT_TRACE' for available trace output options.10441045'GIT_TRACE_PACKET'::1046 Enables trace messages for all packets coming in or out of a1047 given program. This can help with debugging object negotiation1048 or other protocol issues. Tracing is turned off at a packet1049 starting with "PACK" (but see 'GIT_TRACE_PACKFILE' below).1050 See 'GIT_TRACE' for available trace output options.10511052'GIT_TRACE_PACKFILE'::1053 Enables tracing of packfiles sent or received by a1054 given program. Unlike other trace output, this trace is1055 verbatim: no headers, and no quoting of binary data. You almost1056 certainly want to direct into a file (e.g.,1057 `GIT_TRACE_PACKFILE=/tmp/my.pack`) rather than displaying it on1058 the terminal or mixing it with other trace output.1059+1060Note that this is currently only implemented for the client side1061of clones and fetches.10621063'GIT_TRACE_PERFORMANCE'::1064 Enables performance related trace messages, e.g. total execution1065 time of each Git command.1066 See 'GIT_TRACE' for available trace output options.10671068'GIT_TRACE_SETUP'::1069 Enables trace messages printing the .git, working tree and current1070 working directory after Git has completed its setup phase.1071 See 'GIT_TRACE' for available trace output options.10721073'GIT_TRACE_SHALLOW'::1074 Enables trace messages that can help debugging fetching /1075 cloning of shallow repositories.1076 See 'GIT_TRACE' for available trace output options.10771078'GIT_LITERAL_PATHSPECS'::1079 Setting this variable to `1` will cause Git to treat all1080 pathspecs literally, rather than as glob patterns. For example,1081 running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search1082 for commits that touch the path `*.c`, not any paths that the1083 glob `*.c` matches. You might want this if you are feeding1084 literal paths to Git (e.g., paths previously given to you by1085 `git ls-tree`, `--raw` diff output, etc).10861087'GIT_GLOB_PATHSPECS'::1088 Setting this variable to `1` will cause Git to treat all1089 pathspecs as glob patterns (aka "glob" magic).10901091'GIT_NOGLOB_PATHSPECS'::1092 Setting this variable to `1` will cause Git to treat all1093 pathspecs as literal (aka "literal" magic).10941095'GIT_ICASE_PATHSPECS'::1096 Setting this variable to `1` will cause Git to treat all1097 pathspecs as case-insensitive.10981099'GIT_REFLOG_ACTION'::1100 When a ref is updated, reflog entries are created to keep1101 track of the reason why the ref was updated (which is1102 typically the name of the high-level command that updated1103 the ref), in addition to the old and new values of the ref.1104 A scripted Porcelain command can use set_reflog_action1105 helper function in `git-sh-setup` to set its name to this1106 variable when it is invoked as the top level command by the1107 end user, to be recorded in the body of the reflog.11081109'GIT_REF_PARANOIA'::1110 If set to `1`, include broken or badly named refs when iterating1111 over lists of refs. In a normal, non-corrupted repository, this1112 does nothing. However, enabling it may help git to detect and1113 abort some operations in the presence of broken refs. Git sets1114 this variable automatically when performing destructive1115 operations like linkgit:git-prune[1]. You should not need to set1116 it yourself unless you want to be paranoid about making sure1117 an operation has touched every ref (e.g., because you are1118 cloning a repository to make a backup).11191120'GIT_ALLOW_PROTOCOL'::1121 If set, provide a colon-separated list of protocols which are1122 allowed to be used with fetch/push/clone. This is useful to1123 restrict recursive submodule initialization from an untrusted1124 repository. Any protocol not mentioned will be disallowed (i.e.,1125 this is a whitelist, not a blacklist). If the variable is not1126 set at all, all protocols are enabled. The protocol names1127 currently used by git are:11281129 - `file`: any local file-based path (including `file://` URLs,1130 or local paths)11311132 - `git`: the anonymous git protocol over a direct TCP1133 connection (or proxy, if configured)11341135 - `ssh`: git over ssh (including `host:path` syntax,1136 `ssh://`, etc).11371138 - `http`: git over http, both "smart http" and "dumb http".1139 Note that this does _not_ include `https`; if you want both,1140 you should specify both as `http:https`.11411142 - any external helpers are named by their protocol (e.g., use1143 `hg` to allow the `git-remote-hg` helper)114411451146Discussion[[Discussion]]1147------------------------11481149More detail on the following is available from the1150link:user-manual.html#git-concepts[Git concepts chapter of the1151user-manual] and linkgit:gitcore-tutorial[7].11521153A Git project normally consists of a working directory with a ".git"1154subdirectory at the top level. The .git directory contains, among other1155things, a compressed object database representing the complete history1156of the project, an "index" file which links that history to the current1157contents of the working tree, and named pointers into that history such1158as tags and branch heads.11591160The object database contains objects of three main types: blobs, which1161hold file data; trees, which point to blobs and other trees to build up1162directory hierarchies; and commits, which each reference a single tree1163and some number of parent commits.11641165The commit, equivalent to what other systems call a "changeset" or1166"version", represents a step in the project's history, and each parent1167represents an immediately preceding step. Commits with more than one1168parent represent merges of independent lines of development.11691170All objects are named by the SHA-1 hash of their contents, normally1171written as a string of 40 hex digits. Such names are globally unique.1172The entire history leading up to a commit can be vouched for by signing1173just that commit. A fourth object type, the tag, is provided for this1174purpose.11751176When first created, objects are stored in individual files, but for1177efficiency may later be compressed together into "pack files".11781179Named pointers called refs mark interesting points in history. A ref1180may contain the SHA-1 name of an object or the name of another ref. Refs1181with names beginning `ref/head/` contain the SHA-1 name of the most1182recent commit (or "head") of a branch under development. SHA-1 names of1183tags of interest are stored under `ref/tags/`. A special ref named1184`HEAD` contains the name of the currently checked-out branch.11851186The index file is initialized with a list of all paths and, for each1187path, a blob object and a set of attributes. The blob object represents1188the contents of the file as of the head of the current branch. The1189attributes (last modified time, size, etc.) are taken from the1190corresponding file in the working tree. Subsequent changes to the1191working tree can be found by comparing these attributes. The index may1192be updated with new content, and new commits may be created from the1193content stored in the index.11941195The index is also capable of storing multiple entries (called "stages")1196for a given pathname. These stages are used to hold the various1197unmerged version of a file when a merge is in progress.11981199FURTHER DOCUMENTATION1200---------------------12011202See the references in the "description" section to get started1203using Git.
