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

498 499============ 500 501endif::stalenotes[] 502 503OPTIONS 504------- 505--version:: 506 Prints the Git suite version that the 'git' program came from. 507 508--help:: 509 Prints the synopsis and a list of the most commonly used 510 commands. If the option '--all' or '-a' is given then all 511 available commands are printed. If a Git command is named this 512 option will bring up the manual page for that command. 513+ 514Other options are available to control how the manual page is 515displayed. See linkgit:git-help[1] for more information, 516because `git --help ...` is converted internally into `git 517help ...`. 518 519-C <path>:: 520 Run as if git was started in '<path>' instead of the current working 521 directory. When multiple `-C` options are given, each subsequent 522 non-absolute `-C <path>` is interpreted relative to the preceding `-C 523 <path>`. 524+ 525This option affects options that expect path name like `--git-dir` and 526`--work-tree` in that their interpretations of the path names would be 527made relative to the working directory caused by the `-C` option. For 528example the following invocations are equivalent: 529 530 git --git-dir=a.git --work-tree=b -C c status 531 git --git-dir=c/a.git --work-tree=c/b status 532 533-c <name>=<value>:: 534 Pass a configuration parameter to the command. The value 535 given will override values from configuration files. 536 The <name> is expected in the same format as listed by 537 'git config' (subkeys separated by dots). 538+ 539Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets 540`foo.bar` to the boolean true value (just like `[foo]bar` would in a 541config file). Including the equals but with an empty value (like `git -c 542foo.bar= ...`) sets `foo.bar` to the empty string. 543 544--exec-path[=<path>]:: 545 Path to wherever your core Git programs are installed. 546 This can also be controlled by setting the GIT_EXEC_PATH 547 environment variable. If no path is given, 'git' will print 548 the current setting and then exit. 549 550--html-path:: 551 Print the path, without trailing slash, where Git's HTML 552 documentation is installed and exit. 553 554--man-path:: 555 Print the manpath (see `man(1)`) for the man pages for 556 this version of Git and exit. 557 558--info-path:: 559 Print the path where the Info files documenting this 560 version of Git are installed and exit. 561 562-p:: 563--paginate:: 564 Pipe all output into 'less' (or if set, $PAGER) if standard 565 output is a terminal. This overrides the `pager.<cmd>` 566 configuration options (see the "Configuration Mechanism" section 567 below). 568 569--no-pager:: 570 Do not pipe Git output into a pager. 571 572--git-dir=<path>:: 573 Set the path to the repository. This can also be controlled by 574 setting the GIT_DIR environment variable. It can be an absolute 575 path or relative path to current working directory. 576 577--work-tree=<path>:: 578 Set the path to the working tree. It can be an absolute path 579 or a path relative to the current working directory. 580 This can also be controlled by setting the GIT_WORK_TREE 581 environment variable and the core.worktree configuration 582 variable (see core.worktree in linkgit:git-config[1] for a 583 more detailed discussion). 584 585--namespace=<path>:: 586 Set the Git namespace. See linkgit:gitnamespaces[7] for more 587 details. Equivalent to setting the `GIT_NAMESPACE` environment 588 variable. 589 590--bare:: 591 Treat the repository as a bare repository. If GIT_DIR 592 environment is not set, it is set to the current working 593 directory. 594 595--no-replace-objects:: 596 Do not use replacement refs to replace Git objects. See 597 linkgit:git-replace[1] for more information. 598 599--literal-pathspecs:: 600 Treat pathspecs literally (i.e. no globbing, no pathspec magic). 601 This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment 602 variable to `1`. 603 604--glob-pathspecs:: 605 Add "glob" magic to all pathspec. This is equivalent to setting 606 the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling 607 globbing on individual pathspecs can be done using pathspec 608 magic ":(literal)" 609 610--noglob-pathspecs:: 611 Add "literal" magic to all pathspec. This is equivalent to setting 612 the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling 613 globbing on individual pathspecs can be done using pathspec 614 magic ":(glob)" 615 616--icase-pathspecs:: 617 Add "icase" magic to all pathspec. This is equivalent to setting 618 the `GIT_ICASE_PATHSPECS` environment variable to `1`. 619 620GIT COMMANDS 621------------ 622 623We divide Git into high level ("porcelain") commands and low level 624("plumbing") commands. 625 626High-level commands (porcelain) 627------------------------------- 628 629We separate the porcelain commands into the main commands and some 630ancillary user utilities. 631 632Main porcelain commands 633~~~~~~~~~~~~~~~~~~~~~~~ 634 635include::cmds-mainporcelain.txt[] 636 637Ancillary Commands 638~~~~~~~~~~~~~~~~~~ 639Manipulators: 640 641include::cmds-ancillarymanipulators.txt[] 642 643Interrogators: 644 645include::cmds-ancillaryinterrogators.txt[] 646 647 648Interacting with Others 649~~~~~~~~~~~~~~~~~~~~~~~ 650 651These commands are to interact with foreign SCM and with other 652people via patch over e-mail. 653 654include::cmds-foreignscminterface.txt[] 655 656 657Low-level commands (plumbing) 658----------------------------- 659 660Although Git includes its 661own porcelain layer, its low-level commands are sufficient to support 662development of alternative porcelains. Developers of such porcelains 663might start by reading about linkgit:git-update-index[1] and 664linkgit:git-read-tree[1]. 665 666The interface (input, output, set of options and the semantics) 667to these low-level commands are meant to be a lot more stable 668than Porcelain level commands, because these commands are 669primarily for scripted use. The interface to Porcelain commands 670on the other hand are subject to change in order to improve the 671end user experience. 672 673The following description divides 674the low-level commands into commands that manipulate objects (in 675the repository, index, and working tree), commands that interrogate and 676compare objects, and commands that move objects and references between 677repositories. 678 679 680Manipulation commands 681~~~~~~~~~~~~~~~~~~~~~ 682 683include::cmds-plumbingmanipulators.txt[] 684 685 686Interrogation commands 687~~~~~~~~~~~~~~~~~~~~~~ 688 689include::cmds-plumbinginterrogators.txt[] 690 691In general, the interrogate commands do not touch the files in 692the working tree. 693 694 695Synching repositories 696~~~~~~~~~~~~~~~~~~~~~ 697 698include::cmds-synchingrepositories.txt[] 699 700The following are helper commands used by the above; end users 701typically do not use them directly. 702 703include::cmds-synchelpers.txt[] 704 705 706Internal helper commands 707~~~~~~~~~~~~~~~~~~~~~~~~ 708 709These are internal helper commands used by other commands; end 710users typically do not use them directly. 711 712include::cmds-purehelpers.txt[] 713 714 715Configuration Mechanism 716----------------------- 717 718Git uses a simple text format to store customizations that are per 719repository and are per user. Such a configuration file may look 720like this: 721 722------------ 723# 724# A '#' or ';' character indicates a comment. 725# 726 727; core variables 728[core] 729 ; Don't trust file modes 730 filemode = false 731 732; user identity 733[user] 734 name = "Junio C Hamano" 735 email = "gitster@pobox.com" 736 737------------ 738 739Various commands read from the configuration file and adjust 740their operation accordingly. See linkgit:git-config[1] for a 741list and more details about the configuration mechanism. 742 743 744Identifier Terminology 745---------------------- 746<object>:: 747 Indicates the object name for any type of object. 748 749<blob>:: 750 Indicates a blob object name. 751 752<tree>:: 753 Indicates a tree object name. 754 755<commit>:: 756 Indicates a commit object name. 757 758<tree-ish>:: 759 Indicates a tree, commit or tag object name. A 760 command that takes a <tree-ish> argument ultimately wants to 761 operate on a <tree> object but automatically dereferences 762 <commit> and <tag> objects that point at a <tree>. 763 764<commit-ish>:: 765 Indicates a commit or tag object name. A 766 command that takes a <commit-ish> argument ultimately wants to 767 operate on a <commit> object but automatically dereferences 768 <tag> objects that point at a <commit>. 769 770<type>:: 771 Indicates that an object type is required. 772 Currently one of: `blob`, `tree`, `commit`, or `tag`. 773 774<file>:: 775 Indicates a filename - almost always relative to the 776 root of the tree structure `GIT_INDEX_FILE` describes. 777 778Symbolic Identifiers 779-------------------- 780Any Git command accepting any <object> can also use the following 781symbolic notation: 782 783HEAD:: 784 indicates the head of the current branch. 785 786<tag>:: 787 a valid tag 'name' 788 (i.e. a `refs/tags/<tag>` reference). 789 790<head>:: 791 a valid head 'name' 792 (i.e. a `refs/heads/<head>` reference). 793 794For a more complete list of ways to spell object names, see 795"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7]. 796 797 798File/Directory Structure 799------------------------ 800 801Please see the linkgit:gitrepository-layout[5] document. 802 803Read linkgit:githooks[5] for more details about each hook. 804 805Higher level SCMs may provide and manage additional information in the 806`$GIT_DIR`. 807 808 809Terminology 810----------- 811Please see linkgit:gitglossary[7]. 812 813 814Environment Variables 815--------------------- 816Various Git commands use the following environment variables: 817 818The Git Repository 819~~~~~~~~~~~~~~~~~~ 820These environment variables apply to 'all' core Git commands. Nb: it 821is worth noting that they may be used/overridden by SCMS sitting above 822Git so take care if using a foreign front-end. 823 824'GIT_INDEX_FILE':: 825 This environment allows the specification of an alternate 826 index file. If not specified, the default of `$GIT_DIR/index` 827 is used. 828 829'GIT_INDEX_VERSION':: 830 This environment variable allows the specification of an index 831 version for new repositories. It won't affect existing index 832 files. By default index file version 2 or 3 is used. See 833 linkgit:git-update-index[1] for more information. 834 835'GIT_OBJECT_DIRECTORY':: 836 If the object storage directory is specified via this 837 environment variable then the sha1 directories are created 838 underneath - otherwise the default `$GIT_DIR/objects` 839 directory is used. 840 841'GIT_ALTERNATE_OBJECT_DIRECTORIES':: 842 Due to the immutable nature of Git objects, old objects can be 843 archived into shared, read-only directories. This variable 844 specifies a ":" separated (on Windows ";" separated) list 845 of Git object directories which can be used to search for Git 846 objects. New objects will not be written to these directories. 847 848'GIT_DIR':: 849 If the 'GIT_DIR' environment variable is set then it 850 specifies a path to use instead of the default `.git` 851 for the base of the repository. 852 The '--git-dir' command-line option also sets this value. 853 854'GIT_WORK_TREE':: 855 Set the path to the root of the working tree. 856 This can also be controlled by the '--work-tree' command-line 857 option and the core.worktree configuration variable. 858 859'GIT_NAMESPACE':: 860 Set the Git namespace; see linkgit:gitnamespaces[7] for details. 861 The '--namespace' command-line option also sets this value. 862 863'GIT_CEILING_DIRECTORIES':: 864 This should be a colon-separated list of absolute paths. If 865 set, it is a list of directories that Git should not chdir up 866 into while looking for a repository directory (useful for 867 excluding slow-loading network directories). It will not 868 exclude the current working directory or a GIT_DIR set on the 869 command line or in the environment. Normally, Git has to read 870 the entries in this list and resolve any symlink that 871 might be present in order to compare them with the current 872 directory. However, if even this access is slow, you 873 can add an empty entry to the list to tell Git that the 874 subsequent entries are not symlinks and needn't be resolved; 875 e.g., 876 'GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink'. 877 878'GIT_DISCOVERY_ACROSS_FILESYSTEM':: 879 When run in a directory that does not have ".git" repository 880 directory, Git tries to find such a directory in the parent 881 directories to find the top of the working tree, but by default it 882 does not cross filesystem boundaries. This environment variable 883 can be set to true to tell Git not to stop at filesystem 884 boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect 885 an explicit repository directory set via 'GIT_DIR' or on the 886 command line. 887 888'GIT_COMMON_DIR':: 889 If this variable is set to a path, non-worktree files that are 890 normally in $GIT_DIR will be taken from this path 891 instead. Worktree-specific files such as HEAD or index are 892 taken from $GIT_DIR. See linkgit:gitrepository-layout[5] and 893 linkgit:git-worktree[1] for 894 details. This variable has lower precedence than other path 895 variables such as GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY... 896 897Git Commits 898~~~~~~~~~~~ 899'GIT_AUTHOR_NAME':: 900'GIT_AUTHOR_EMAIL':: 901'GIT_AUTHOR_DATE':: 902'GIT_COMMITTER_NAME':: 903'GIT_COMMITTER_EMAIL':: 904'GIT_COMMITTER_DATE':: 905'EMAIL':: 906 see linkgit:git-commit-tree[1] 907 908Git Diffs 909~~~~~~~~~ 910'GIT_DIFF_OPTS':: 911 Only valid setting is "--unified=??" or "-u??" to set the 912 number of context lines shown when a unified diff is created. 913 This takes precedence over any "-U" or "--unified" option 914 value passed on the Git diff command line. 915 916'GIT_EXTERNAL_DIFF':: 917 When the environment variable 'GIT_EXTERNAL_DIFF' is set, the 918 program named by it is called, instead of the diff invocation 919 described above. For a path that is added, removed, or modified, 920 'GIT_EXTERNAL_DIFF' is called with 7 parameters: 921 922 path old-file old-hex old-mode new-file new-hex new-mode 923+ 924where: 925 926 <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the 927 contents of <old|new>, 928 <old|new>-hex:: are the 40-hexdigit SHA-1 hashes, 929 <old|new>-mode:: are the octal representation of the file modes. 930+ 931The file parameters can point at the user's working file 932(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file` 933when a new file is added), or a temporary file (e.g. `old-file` in the 934index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the 935temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits. 936+ 937For a path that is unmerged, 'GIT_EXTERNAL_DIFF' is called with 1 938parameter, <path>. 939+ 940For each path 'GIT_EXTERNAL_DIFF' is called, two environment variables, 941'GIT_DIFF_PATH_COUNTER' and 'GIT_DIFF_PATH_TOTAL' are set. 942 943'GIT_DIFF_PATH_COUNTER':: 944 A 1-based counter incremented by one for every path. 945 946'GIT_DIFF_PATH_TOTAL':: 947 The total number of paths. 948 949other 950~~~~~ 951'GIT_MERGE_VERBOSITY':: 952 A number controlling the amount of output shown by 953 the recursive merge strategy. Overrides merge.verbosity. 954 See linkgit:git-merge[1] 955 956'GIT_PAGER':: 957 This environment variable overrides `$PAGER`. If it is set 958 to an empty string or to the value "cat", Git will not launch 959 a pager. See also the `core.pager` option in 960 linkgit:git-config[1]. 961 962'GIT_EDITOR':: 963 This environment variable overrides `$EDITOR` and `$VISUAL`. 964 It is used by several Git commands when, on interactive mode, 965 an editor is to be launched. See also linkgit:git-var[1] 966 and the `core.editor` option in linkgit:git-config[1]. 967 968'GIT_SSH':: 969'GIT_SSH_COMMAND':: 970 If either of these environment variables is set then 'git fetch' 971 and 'git push' will use the specified command instead of 'ssh' 972 when they need to connect to a remote system. 973 The command will be given exactly two or four arguments: the 974 'username@host' (or just 'host') from the URL and the shell 975 command to execute on that remote system, optionally preceded by 976 '-p' (literally) and the 'port' from the URL when it specifies 977 something other than the default SSH port. 978+ 979`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted 980by the shell, which allows additional arguments to be included. 981`$GIT_SSH` on the other hand must be just the path to a program 982(which can be a wrapper shell script, if additional arguments are 983needed). 984+ 985Usually it is easier to configure any desired options through your 986personal `.ssh/config` file. Please consult your ssh documentation 987for further details. 988 989'GIT_ASKPASS':: 990 If this environment variable is set, then Git commands which need to 991 acquire passwords or passphrases (e.g. for HTTP or IMAP authentication) 992 will call this program with a suitable prompt as command-line argument 993 and read the password from its STDOUT. See also the 'core.askPass' 994 option in linkgit:git-config[1]. 995 996'GIT_TERMINAL_PROMPT':: 997 If this environment variable is set to `0`, git will not prompt 998 on the terminal (e.g., when asking for HTTP authentication). 9991000'GIT_CONFIG_NOSYSTEM'::1001 Whether to skip reading settings from the system-wide1002 `$(prefix)/etc/gitconfig` file. This environment variable can1003 be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a1004 predictable environment for a picky script, or you can set it1005 temporarily to avoid using a buggy `/etc/gitconfig` file while1006 waiting for someone with sufficient permissions to fix it.10071008'GIT_FLUSH'::1009 If this environment variable is set to "1", then commands such1010 as 'git blame' (in incremental mode), 'git rev-list', 'git log',1011 'git check-attr' and 'git check-ignore' will1012 force a flush of the output stream after each record have been1013 flushed. If this1014 variable is set to "0", the output of these commands will be done1015 using completely buffered I/O. If this environment variable is1016 not set, Git will choose buffered or record-oriented flushing1017 based on whether stdout appears to be redirected to a file or not.10181019'GIT_TRACE'::1020 Enables general trace messages, e.g. alias expansion, built-in1021 command execution and external command execution.1022+1023If this variable is set to "1", "2" or "true" (comparison1024is case insensitive), trace messages will be printed to1025stderr.1026+1027If the variable is set to an integer value greater than 21028and lower than 10 (strictly) then Git will interpret this1029value as an open file descriptor and will try to write the1030trace messages into this file descriptor.1031+1032Alternatively, if the variable is set to an absolute path1033(starting with a '/' character), Git will interpret this1034as a file path and will try to write the trace messages1035into it.1036+1037Unsetting the variable, or setting it to empty, "0" or1038"false" (case insensitive) disables trace messages.10391040'GIT_TRACE_PACK_ACCESS'::1041 Enables trace messages for all accesses to any packs. For each1042 access, the pack file name and an offset in the pack is1043 recorded. This may be helpful for troubleshooting some1044 pack-related performance problems.1045 See 'GIT_TRACE' for available trace output options.10461047'GIT_TRACE_PACKET'::1048 Enables trace messages for all packets coming in or out of a1049 given program. This can help with debugging object negotiation1050 or other protocol issues. Tracing is turned off at a packet1051 starting with "PACK" (but see 'GIT_TRACE_PACKFILE' below).1052 See 'GIT_TRACE' for available trace output options.10531054'GIT_TRACE_PACKFILE'::1055 Enables tracing of packfiles sent or received by a1056 given program. Unlike other trace output, this trace is1057 verbatim: no headers, and no quoting of binary data. You almost1058 certainly want to direct into a file (e.g.,1059 `GIT_TRACE_PACKFILE=/tmp/my.pack`) rather than displaying it on1060 the terminal or mixing it with other trace output.1061+1062Note that this is currently only implemented for the client side1063of clones and fetches.10641065'GIT_TRACE_PERFORMANCE'::1066 Enables performance related trace messages, e.g. total execution1067 time of each Git command.1068 See 'GIT_TRACE' for available trace output options.10691070'GIT_TRACE_SETUP'::1071 Enables trace messages printing the .git, working tree and current1072 working directory after Git has completed its setup phase.1073 See 'GIT_TRACE' for available trace output options.10741075'GIT_TRACE_SHALLOW'::1076 Enables trace messages that can help debugging fetching /1077 cloning of shallow repositories.1078 See 'GIT_TRACE' for available trace output options.10791080'GIT_LITERAL_PATHSPECS'::1081 Setting this variable to `1` will cause Git to treat all1082 pathspecs literally, rather than as glob patterns. For example,1083 running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search1084 for commits that touch the path `*.c`, not any paths that the1085 glob `*.c` matches. You might want this if you are feeding1086 literal paths to Git (e.g., paths previously given to you by1087 `git ls-tree`, `--raw` diff output, etc).10881089'GIT_GLOB_PATHSPECS'::1090 Setting this variable to `1` will cause Git to treat all1091 pathspecs as glob patterns (aka "glob" magic).10921093'GIT_NOGLOB_PATHSPECS'::1094 Setting this variable to `1` will cause Git to treat all1095 pathspecs as literal (aka "literal" magic).10961097'GIT_ICASE_PATHSPECS'::1098 Setting this variable to `1` will cause Git to treat all1099 pathspecs as case-insensitive.11001101'GIT_REFLOG_ACTION'::1102 When a ref is updated, reflog entries are created to keep1103 track of the reason why the ref was updated (which is1104 typically the name of the high-level command that updated1105 the ref), in addition to the old and new values of the ref.1106 A scripted Porcelain command can use set_reflog_action1107 helper function in `git-sh-setup` to set its name to this1108 variable when it is invoked as the top level command by the1109 end user, to be recorded in the body of the reflog.11101111'GIT_REF_PARANOIA'::1112 If set to `1`, include broken or badly named refs when iterating1113 over lists of refs. In a normal, non-corrupted repository, this1114 does nothing. However, enabling it may help git to detect and1115 abort some operations in the presence of broken refs. Git sets1116 this variable automatically when performing destructive1117 operations like linkgit:git-prune[1]. You should not need to set1118 it yourself unless you want to be paranoid about making sure1119 an operation has touched every ref (e.g., because you are1120 cloning a repository to make a backup).11211122'GIT_ALLOW_PROTOCOL'::1123 If set, provide a colon-separated list of protocols which are1124 allowed to be used with fetch/push/clone. This is useful to1125 restrict recursive submodule initialization from an untrusted1126 repository. Any protocol not mentioned will be disallowed (i.e.,1127 this is a whitelist, not a blacklist). If the variable is not1128 set at all, all protocols are enabled. The protocol names1129 currently used by git are:11301131 - `file`: any local file-based path (including `file://` URLs,1132 or local paths)11331134 - `git`: the anonymous git protocol over a direct TCP1135 connection (or proxy, if configured)11361137 - `ssh`: git over ssh (including `host:path` syntax,1138 `ssh://`, etc).11391140 - `http`: git over http, both "smart http" and "dumb http".1141 Note that this does _not_ include `https`; if you want both,1142 you should specify both as `http:https`.11431144 - any external helpers are named by their protocol (e.g., use1145 `hg` to allow the `git-remote-hg` helper)114611471148Discussion[[Discussion]]1149------------------------11501151More detail on the following is available from the1152link:user-manual.html#git-concepts[Git concepts chapter of the1153user-manual] and linkgit:gitcore-tutorial[7].11541155A Git project normally consists of a working directory with a ".git"1156subdirectory at the top level. The .git directory contains, among other1157things, a compressed object database representing the complete history1158of the project, an "index" file which links that history to the current1159contents of the working tree, and named pointers into that history such1160as tags and branch heads.11611162The object database contains objects of three main types: blobs, which1163hold file data; trees, which point to blobs and other trees to build up1164directory hierarchies; and commits, which each reference a single tree1165and some number of parent commits.11661167The commit, equivalent to what other systems call a "changeset" or1168"version", represents a step in the project's history, and each parent1169represents an immediately preceding step. Commits with more than one1170parent represent merges of independent lines of development.11711172All objects are named by the SHA-1 hash of their contents, normally1173written as a string of 40 hex digits. Such names are globally unique.1174The entire history leading up to a commit can be vouched for by signing1175just that commit. A fourth object type, the tag, is provided for this1176purpose.11771178When first created, objects are stored in individual files, but for1179efficiency may later be compressed together into "pack files".11801181Named pointers called refs mark interesting points in history. A ref1182may contain the SHA-1 name of an object or the name of another ref. Refs1183with names beginning `ref/head/` contain the SHA-1 name of the most1184recent commit (or "head") of a branch under development. SHA-1 names of1185tags of interest are stored under `ref/tags/`. A special ref named1186`HEAD` contains the name of the currently checked-out branch.11871188The index file is initialized with a list of all paths and, for each1189path, a blob object and a set of attributes. The blob object represents1190the contents of the file as of the head of the current branch. The1191attributes (last modified time, size, etc.) are taken from the1192corresponding file in the working tree. Subsequent changes to the1193working tree can be found by comparing these attributes. The index may1194be updated with new content, and new commits may be created from the1195content stored in the index.11961197The index is also capable of storing multiple entries (called "stages")1198for a given pathname. These stages are used to hold the various1199unmerged version of a file when a merge is in progress.12001201FURTHER DOCUMENTATION1202---------------------12031204See the references in the "description" section to get started1205using Git.
