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

497 498============ 499 500endif::stalenotes[] 501 502OPTIONS 503------- 504--version:: 505 Prints the Git suite version that the 'git' program came from. 506 507--help:: 508 Prints the synopsis and a list of the most commonly used 509 commands. If the option '--all' or '-a' is given then all 510 available commands are printed. If a Git command is named this 511 option will bring up the manual page for that command. 512+ 513Other options are available to control how the manual page is 514displayed. See linkgit:git-help[1] for more information, 515because `git --help ...` is converted internally into `git 516help ...`. 517 518-C <path>:: 519 Run as if git was started in '<path>' instead of the current working 520 directory. When multiple `-C` options are given, each subsequent 521 non-absolute `-C <path>` is interpreted relative to the preceding `-C 522 <path>`. 523+ 524This option affects options that expect path name like `--git-dir` and 525`--work-tree` in that their interpretations of the path names would be 526made relative to the working directory caused by the `-C` option. For 527example the following invocations are equivalent: 528 529 git --git-dir=a.git --work-tree=b -C c status 530 git --git-dir=c/a.git --work-tree=c/b status 531 532-c <name>=<value>:: 533 Pass a configuration parameter to the command. The value 534 given will override values from configuration files. 535 The <name> is expected in the same format as listed by 536 'git config' (subkeys separated by dots). 537+ 538Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets 539`foo.bar` to the boolean true value (just like `[foo]bar` would in a 540config file). Including the equals but with an empty value (like `git -c 541foo.bar= ...`) sets `foo.bar` to the empty string. 542 543--exec-path[=<path>]:: 544 Path to wherever your core Git programs are installed. 545 This can also be controlled by setting the GIT_EXEC_PATH 546 environment variable. If no path is given, 'git' will print 547 the current setting and then exit. 548 549--html-path:: 550 Print the path, without trailing slash, where Git's HTML 551 documentation is installed and exit. 552 553--man-path:: 554 Print the manpath (see `man(1)`) for the man pages for 555 this version of Git and exit. 556 557--info-path:: 558 Print the path where the Info files documenting this 559 version of Git are installed and exit. 560 561-p:: 562--paginate:: 563 Pipe all output into 'less' (or if set, $PAGER) if standard 564 output is a terminal. This overrides the `pager.<cmd>` 565 configuration options (see the "Configuration Mechanism" section 566 below). 567 568--no-pager:: 569 Do not pipe Git output into a pager. 570 571--git-dir=<path>:: 572 Set the path to the repository. This can also be controlled by 573 setting the GIT_DIR environment variable. It can be an absolute 574 path or relative path to current working directory. 575 576--work-tree=<path>:: 577 Set the path to the working tree. It can be an absolute path 578 or a path relative to the current working directory. 579 This can also be controlled by setting the GIT_WORK_TREE 580 environment variable and the core.worktree configuration 581 variable (see core.worktree in linkgit:git-config[1] for a 582 more detailed discussion). 583 584--namespace=<path>:: 585 Set the Git namespace. See linkgit:gitnamespaces[7] for more 586 details. Equivalent to setting the `GIT_NAMESPACE` environment 587 variable. 588 589--bare:: 590 Treat the repository as a bare repository. If GIT_DIR 591 environment is not set, it is set to the current working 592 directory. 593 594--no-replace-objects:: 595 Do not use replacement refs to replace Git objects. See 596 linkgit:git-replace[1] for more information. 597 598--literal-pathspecs:: 599 Treat pathspecs literally (i.e. no globbing, no pathspec magic). 600 This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment 601 variable to `1`. 602 603--glob-pathspecs:: 604 Add "glob" magic to all pathspec. This is equivalent to setting 605 the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling 606 globbing on individual pathspecs can be done using pathspec 607 magic ":(literal)" 608 609--noglob-pathspecs:: 610 Add "literal" magic to all pathspec. This is equivalent to setting 611 the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling 612 globbing on individual pathspecs can be done using pathspec 613 magic ":(glob)" 614 615--icase-pathspecs:: 616 Add "icase" magic to all pathspec. This is equivalent to setting 617 the `GIT_ICASE_PATHSPECS` environment variable to `1`. 618 619GIT COMMANDS 620------------ 621 622We divide Git into high level ("porcelain") commands and low level 623("plumbing") commands. 624 625High-level commands (porcelain) 626------------------------------- 627 628We separate the porcelain commands into the main commands and some 629ancillary user utilities. 630 631Main porcelain commands 632~~~~~~~~~~~~~~~~~~~~~~~ 633 634include::cmds-mainporcelain.txt[] 635 636Ancillary Commands 637~~~~~~~~~~~~~~~~~~ 638Manipulators: 639 640include::cmds-ancillarymanipulators.txt[] 641 642Interrogators: 643 644include::cmds-ancillaryinterrogators.txt[] 645 646 647Interacting with Others 648~~~~~~~~~~~~~~~~~~~~~~~ 649 650These commands are to interact with foreign SCM and with other 651people via patch over e-mail. 652 653include::cmds-foreignscminterface.txt[] 654 655 656Low-level commands (plumbing) 657----------------------------- 658 659Although Git includes its 660own porcelain layer, its low-level commands are sufficient to support 661development of alternative porcelains. Developers of such porcelains 662might start by reading about linkgit:git-update-index[1] and 663linkgit:git-read-tree[1]. 664 665The interface (input, output, set of options and the semantics) 666to these low-level commands are meant to be a lot more stable 667than Porcelain level commands, because these commands are 668primarily for scripted use. The interface to Porcelain commands 669on the other hand are subject to change in order to improve the 670end user experience. 671 672The following description divides 673the low-level commands into commands that manipulate objects (in 674the repository, index, and working tree), commands that interrogate and 675compare objects, and commands that move objects and references between 676repositories. 677 678 679Manipulation commands 680~~~~~~~~~~~~~~~~~~~~~ 681 682include::cmds-plumbingmanipulators.txt[] 683 684 685Interrogation commands 686~~~~~~~~~~~~~~~~~~~~~~ 687 688include::cmds-plumbinginterrogators.txt[] 689 690In general, the interrogate commands do not touch the files in 691the working tree. 692 693 694Synching repositories 695~~~~~~~~~~~~~~~~~~~~~ 696 697include::cmds-synchingrepositories.txt[] 698 699The following are helper commands used by the above; end users 700typically do not use them directly. 701 702include::cmds-synchelpers.txt[] 703 704 705Internal helper commands 706~~~~~~~~~~~~~~~~~~~~~~~~ 707 708These are internal helper commands used by other commands; end 709users typically do not use them directly. 710 711include::cmds-purehelpers.txt[] 712 713 714Configuration Mechanism 715----------------------- 716 717Git uses a simple text format to store customizations that are per 718repository and are per user. Such a configuration file may look 719like this: 720 721------------ 722# 723# A '#' or ';' character indicates a comment. 724# 725 726; core variables 727[core] 728 ; Don't trust file modes 729 filemode = false 730 731; user identity 732[user] 733 name = "Junio C Hamano" 734 email = "gitster@pobox.com" 735 736------------ 737 738Various commands read from the configuration file and adjust 739their operation accordingly. See linkgit:git-config[1] for a 740list and more details about the configuration mechanism. 741 742 743Identifier Terminology 744---------------------- 745<object>:: 746 Indicates the object name for any type of object. 747 748<blob>:: 749 Indicates a blob object name. 750 751<tree>:: 752 Indicates a tree object name. 753 754<commit>:: 755 Indicates a commit object name. 756 757<tree-ish>:: 758 Indicates a tree, commit or tag object name. A 759 command that takes a <tree-ish> argument ultimately wants to 760 operate on a <tree> object but automatically dereferences 761 <commit> and <tag> objects that point at a <tree>. 762 763<commit-ish>:: 764 Indicates a commit or tag object name. A 765 command that takes a <commit-ish> argument ultimately wants to 766 operate on a <commit> object but automatically dereferences 767 <tag> objects that point at a <commit>. 768 769<type>:: 770 Indicates that an object type is required. 771 Currently one of: `blob`, `tree`, `commit`, or `tag`. 772 773<file>:: 774 Indicates a filename - almost always relative to the 775 root of the tree structure `GIT_INDEX_FILE` describes. 776 777Symbolic Identifiers 778-------------------- 779Any Git command accepting any <object> can also use the following 780symbolic notation: 781 782HEAD:: 783 indicates the head of the current branch. 784 785<tag>:: 786 a valid tag 'name' 787 (i.e. a `refs/tags/<tag>` reference). 788 789<head>:: 790 a valid head 'name' 791 (i.e. a `refs/heads/<head>` reference). 792 793For a more complete list of ways to spell object names, see 794"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7]. 795 796 797File/Directory Structure 798------------------------ 799 800Please see the linkgit:gitrepository-layout[5] document. 801 802Read linkgit:githooks[5] for more details about each hook. 803 804Higher level SCMs may provide and manage additional information in the 805`$GIT_DIR`. 806 807 808Terminology 809----------- 810Please see linkgit:gitglossary[7]. 811 812 813Environment Variables 814--------------------- 815Various Git commands use the following environment variables: 816 817The Git Repository 818~~~~~~~~~~~~~~~~~~ 819These environment variables apply to 'all' core Git commands. Nb: it 820is worth noting that they may be used/overridden by SCMS sitting above 821Git so take care if using a foreign front-end. 822 823'GIT_INDEX_FILE':: 824 This environment allows the specification of an alternate 825 index file. If not specified, the default of `$GIT_DIR/index` 826 is used. 827 828'GIT_INDEX_VERSION':: 829 This environment variable allows the specification of an index 830 version for new repositories. It won't affect existing index 831 files. By default index file version 2 or 3 is used. See 832 linkgit:git-update-index[1] for more information. 833 834'GIT_OBJECT_DIRECTORY':: 835 If the object storage directory is specified via this 836 environment variable then the sha1 directories are created 837 underneath - otherwise the default `$GIT_DIR/objects` 838 directory is used. 839 840'GIT_ALTERNATE_OBJECT_DIRECTORIES':: 841 Due to the immutable nature of Git objects, old objects can be 842 archived into shared, read-only directories. This variable 843 specifies a ":" separated (on Windows ";" separated) list 844 of Git object directories which can be used to search for Git 845 objects. New objects will not be written to these directories. 846 847'GIT_DIR':: 848 If the 'GIT_DIR' environment variable is set then it 849 specifies a path to use instead of the default `.git` 850 for the base of the repository. 851 The '--git-dir' command-line option also sets this value. 852 853'GIT_WORK_TREE':: 854 Set the path to the root of the working tree. 855 This can also be controlled by the '--work-tree' command-line 856 option and the core.worktree configuration variable. 857 858'GIT_NAMESPACE':: 859 Set the Git namespace; see linkgit:gitnamespaces[7] for details. 860 The '--namespace' command-line option also sets this value. 861 862'GIT_CEILING_DIRECTORIES':: 863 This should be a colon-separated list of absolute paths. If 864 set, it is a list of directories that Git should not chdir up 865 into while looking for a repository directory (useful for 866 excluding slow-loading network directories). It will not 867 exclude the current working directory or a GIT_DIR set on the 868 command line or in the environment. Normally, Git has to read 869 the entries in this list and resolve any symlink that 870 might be present in order to compare them with the current 871 directory. However, if even this access is slow, you 872 can add an empty entry to the list to tell Git that the 873 subsequent entries are not symlinks and needn't be resolved; 874 e.g., 875 'GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink'. 876 877'GIT_DISCOVERY_ACROSS_FILESYSTEM':: 878 When run in a directory that does not have ".git" repository 879 directory, Git tries to find such a directory in the parent 880 directories to find the top of the working tree, but by default it 881 does not cross filesystem boundaries. This environment variable 882 can be set to true to tell Git not to stop at filesystem 883 boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect 884 an explicit repository directory set via 'GIT_DIR' or on the 885 command line. 886 887'GIT_COMMON_DIR':: 888 If this variable is set to a path, non-worktree files that are 889 normally in $GIT_DIR will be taken from this path 890 instead. Worktree-specific files such as HEAD or index are 891 taken from $GIT_DIR. See linkgit:gitrepository-layout[5] and 892 linkgit:git-worktree[1] for 893 details. This variable has lower precedence than other path 894 variables such as GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY... 895 896Git Commits 897~~~~~~~~~~~ 898'GIT_AUTHOR_NAME':: 899'GIT_AUTHOR_EMAIL':: 900'GIT_AUTHOR_DATE':: 901'GIT_COMMITTER_NAME':: 902'GIT_COMMITTER_EMAIL':: 903'GIT_COMMITTER_DATE':: 904'EMAIL':: 905 see linkgit:git-commit-tree[1] 906 907Git Diffs 908~~~~~~~~~ 909'GIT_DIFF_OPTS':: 910 Only valid setting is "--unified=??" or "-u??" to set the 911 number of context lines shown when a unified diff is created. 912 This takes precedence over any "-U" or "--unified" option 913 value passed on the Git diff command line. 914 915'GIT_EXTERNAL_DIFF':: 916 When the environment variable 'GIT_EXTERNAL_DIFF' is set, the 917 program named by it is called, instead of the diff invocation 918 described above. For a path that is added, removed, or modified, 919 'GIT_EXTERNAL_DIFF' is called with 7 parameters: 920 921 path old-file old-hex old-mode new-file new-hex new-mode 922+ 923where: 924 925 <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the 926 contents of <old|new>, 927 <old|new>-hex:: are the 40-hexdigit SHA-1 hashes, 928 <old|new>-mode:: are the octal representation of the file modes. 929+ 930The file parameters can point at the user's working file 931(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file` 932when a new file is added), or a temporary file (e.g. `old-file` in the 933index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the 934temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits. 935+ 936For a path that is unmerged, 'GIT_EXTERNAL_DIFF' is called with 1 937parameter, <path>. 938+ 939For each path 'GIT_EXTERNAL_DIFF' is called, two environment variables, 940'GIT_DIFF_PATH_COUNTER' and 'GIT_DIFF_PATH_TOTAL' are set. 941 942'GIT_DIFF_PATH_COUNTER':: 943 A 1-based counter incremented by one for every path. 944 945'GIT_DIFF_PATH_TOTAL':: 946 The total number of paths. 947 948other 949~~~~~ 950'GIT_MERGE_VERBOSITY':: 951 A number controlling the amount of output shown by 952 the recursive merge strategy. Overrides merge.verbosity. 953 See linkgit:git-merge[1] 954 955'GIT_PAGER':: 956 This environment variable overrides `$PAGER`. If it is set 957 to an empty string or to the value "cat", Git will not launch 958 a pager. See also the `core.pager` option in 959 linkgit:git-config[1]. 960 961'GIT_EDITOR':: 962 This environment variable overrides `$EDITOR` and `$VISUAL`. 963 It is used by several Git commands when, on interactive mode, 964 an editor is to be launched. See also linkgit:git-var[1] 965 and the `core.editor` option in linkgit:git-config[1]. 966 967'GIT_SSH':: 968'GIT_SSH_COMMAND':: 969 If either of these environment variables is set then 'git fetch' 970 and 'git push' will use the specified command instead of 'ssh' 971 when they need to connect to a remote system. 972 The command will be given exactly two or four arguments: the 973 'username@host' (or just 'host') from the URL and the shell 974 command to execute on that remote system, optionally preceded by 975 '-p' (literally) and the 'port' from the URL when it specifies 976 something other than the default SSH port. 977+ 978`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted 979by the shell, which allows additional arguments to be included. 980`$GIT_SSH` on the other hand must be just the path to a program 981(which can be a wrapper shell script, if additional arguments are 982needed). 983+ 984Usually it is easier to configure any desired options through your 985personal `.ssh/config` file. Please consult your ssh documentation 986for further details. 987 988'GIT_ASKPASS':: 989 If this environment variable is set, then Git commands which need to 990 acquire passwords or passphrases (e.g. for HTTP or IMAP authentication) 991 will call this program with a suitable prompt as command-line argument 992 and read the password from its STDOUT. See also the 'core.askPass' 993 option in linkgit:git-config[1]. 994 995'GIT_TERMINAL_PROMPT':: 996 If this environment variable is set to `0`, git will not prompt 997 on the terminal (e.g., when asking for HTTP authentication). 998 999'GIT_CONFIG_NOSYSTEM'::1000 Whether to skip reading settings from the system-wide1001 `$(prefix)/etc/gitconfig` file. This environment variable can1002 be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a1003 predictable environment for a picky script, or you can set it1004 temporarily to avoid using a buggy `/etc/gitconfig` file while1005 waiting for someone with sufficient permissions to fix it.10061007'GIT_FLUSH'::1008 If this environment variable is set to "1", then commands such1009 as 'git blame' (in incremental mode), 'git rev-list', 'git log',1010 'git check-attr' and 'git check-ignore' will1011 force a flush of the output stream after each record have been1012 flushed. If this1013 variable is set to "0", the output of these commands will be done1014 using completely buffered I/O. If this environment variable is1015 not set, Git will choose buffered or record-oriented flushing1016 based on whether stdout appears to be redirected to a file or not.10171018'GIT_TRACE'::1019 Enables general trace messages, e.g. alias expansion, built-in1020 command execution and external command execution.1021+1022If this variable is set to "1", "2" or "true" (comparison1023is case insensitive), trace messages will be printed to1024stderr.1025+1026If the variable is set to an integer value greater than 21027and lower than 10 (strictly) then Git will interpret this1028value as an open file descriptor and will try to write the1029trace messages into this file descriptor.1030+1031Alternatively, if the variable is set to an absolute path1032(starting with a '/' character), Git will interpret this1033as a file path and will try to write the trace messages1034into it.1035+1036Unsetting the variable, or setting it to empty, "0" or1037"false" (case insensitive) disables trace messages.10381039'GIT_TRACE_PACK_ACCESS'::1040 Enables trace messages for all accesses to any packs. For each1041 access, the pack file name and an offset in the pack is1042 recorded. This may be helpful for troubleshooting some1043 pack-related performance problems.1044 See 'GIT_TRACE' for available trace output options.10451046'GIT_TRACE_PACKET'::1047 Enables trace messages for all packets coming in or out of a1048 given program. This can help with debugging object negotiation1049 or other protocol issues. Tracing is turned off at a packet1050 starting with "PACK" (but see 'GIT_TRACE_PACKFILE' below).1051 See 'GIT_TRACE' for available trace output options.10521053'GIT_TRACE_PACKFILE'::1054 Enables tracing of packfiles sent or received by a1055 given program. Unlike other trace output, this trace is1056 verbatim: no headers, and no quoting of binary data. You almost1057 certainly want to direct into a file (e.g.,1058 `GIT_TRACE_PACKFILE=/tmp/my.pack`) rather than displaying it on1059 the terminal or mixing it with other trace output.1060+1061Note that this is currently only implemented for the client side1062of clones and fetches.10631064'GIT_TRACE_PERFORMANCE'::1065 Enables performance related trace messages, e.g. total execution1066 time of each Git command.1067 See 'GIT_TRACE' for available trace output options.10681069'GIT_TRACE_SETUP'::1070 Enables trace messages printing the .git, working tree and current1071 working directory after Git has completed its setup phase.1072 See 'GIT_TRACE' for available trace output options.10731074'GIT_TRACE_SHALLOW'::1075 Enables trace messages that can help debugging fetching /1076 cloning of shallow repositories.1077 See 'GIT_TRACE' for available trace output options.10781079'GIT_LITERAL_PATHSPECS'::1080 Setting this variable to `1` will cause Git to treat all1081 pathspecs literally, rather than as glob patterns. For example,1082 running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search1083 for commits that touch the path `*.c`, not any paths that the1084 glob `*.c` matches. You might want this if you are feeding1085 literal paths to Git (e.g., paths previously given to you by1086 `git ls-tree`, `--raw` diff output, etc).10871088'GIT_GLOB_PATHSPECS'::1089 Setting this variable to `1` will cause Git to treat all1090 pathspecs as glob patterns (aka "glob" magic).10911092'GIT_NOGLOB_PATHSPECS'::1093 Setting this variable to `1` will cause Git to treat all1094 pathspecs as literal (aka "literal" magic).10951096'GIT_ICASE_PATHSPECS'::1097 Setting this variable to `1` will cause Git to treat all1098 pathspecs as case-insensitive.10991100'GIT_REFLOG_ACTION'::1101 When a ref is updated, reflog entries are created to keep1102 track of the reason why the ref was updated (which is1103 typically the name of the high-level command that updated1104 the ref), in addition to the old and new values of the ref.1105 A scripted Porcelain command can use set_reflog_action1106 helper function in `git-sh-setup` to set its name to this1107 variable when it is invoked as the top level command by the1108 end user, to be recorded in the body of the reflog.11091110'GIT_REF_PARANOIA'::1111 If set to `1`, include broken or badly named refs when iterating1112 over lists of refs. In a normal, non-corrupted repository, this1113 does nothing. However, enabling it may help git to detect and1114 abort some operations in the presence of broken refs. Git sets1115 this variable automatically when performing destructive1116 operations like linkgit:git-prune[1]. You should not need to set1117 it yourself unless you want to be paranoid about making sure1118 an operation has touched every ref (e.g., because you are1119 cloning a repository to make a backup).11201121'GIT_ALLOW_PROTOCOL'::1122 If set, provide a colon-separated list of protocols which are1123 allowed to be used with fetch/push/clone. This is useful to1124 restrict recursive submodule initialization from an untrusted1125 repository. Any protocol not mentioned will be disallowed (i.e.,1126 this is a whitelist, not a blacklist). If the variable is not1127 set at all, all protocols are enabled. The protocol names1128 currently used by git are:11291130 - `file`: any local file-based path (including `file://` URLs,1131 or local paths)11321133 - `git`: the anonymous git protocol over a direct TCP1134 connection (or proxy, if configured)11351136 - `ssh`: git over ssh (including `host:path` syntax,1137 `ssh://`, etc).11381139 - `http`: git over http, both "smart http" and "dumb http".1140 Note that this does _not_ include `https`; if you want both,1141 you should specify both as `http:https`.11421143 - any external helpers are named by their protocol (e.g., use1144 `hg` to allow the `git-remote-hg` helper)114511461147Discussion[[Discussion]]1148------------------------11491150More detail on the following is available from the1151link:user-manual.html#git-concepts[Git concepts chapter of the1152user-manual] and linkgit:gitcore-tutorial[7].11531154A Git project normally consists of a working directory with a ".git"1155subdirectory at the top level. The .git directory contains, among other1156things, a compressed object database representing the complete history1157of the project, an "index" file which links that history to the current1158contents of the working tree, and named pointers into that history such1159as tags and branch heads.11601161The object database contains objects of three main types: blobs, which1162hold file data; trees, which point to blobs and other trees to build up1163directory hierarchies; and commits, which each reference a single tree1164and some number of parent commits.11651166The commit, equivalent to what other systems call a "changeset" or1167"version", represents a step in the project's history, and each parent1168represents an immediately preceding step. Commits with more than one1169parent represent merges of independent lines of development.11701171All objects are named by the SHA-1 hash of their contents, normally1172written as a string of 40 hex digits. Such names are globally unique.1173The entire history leading up to a commit can be vouched for by signing1174just that commit. A fourth object type, the tag, is provided for this1175purpose.11761177When first created, objects are stored in individual files, but for1178efficiency may later be compressed together into "pack files".11791180Named pointers called refs mark interesting points in history. A ref1181may contain the SHA-1 name of an object or the name of another ref. Refs1182with names beginning `ref/head/` contain the SHA-1 name of the most1183recent commit (or "head") of a branch under development. SHA-1 names of1184tags of interest are stored under `ref/tags/`. A special ref named1185`HEAD` contains the name of the currently checked-out branch.11861187The index file is initialized with a list of all paths and, for each1188path, a blob object and a set of attributes. The blob object represents1189the contents of the file as of the head of the current branch. The1190attributes (last modified time, size, etc.) are taken from the1191corresponding file in the working tree. Subsequent changes to the1192working tree can be found by comparing these attributes. The index may1193be updated with new content, and new commits may be created from the1194content stored in the index.11951196The index is also capable of storing multiple entries (called "stages")1197for a given pathname. These stages are used to hold the various1198unmerged version of a file when a merge is in progress.11991200FURTHER DOCUMENTATION1201---------------------12021203See the references in the "description" section to get started1204using Git.
