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. 502 503--help:: 504 Prints the synopsis and a list of the most commonly used 505 commands. If the option '--all' or '-a' is given then all 506 available commands are printed. If a Git command is named this 507 option will bring up the manual page for that command. 508+ 509Other options are available to control how the manual page is 510displayed. See linkgit:git-help[1] for more information, 511because `git --help ...` is converted internally into `git 512help ...`. 513 514-C <path>:: 515 Run as if git was started in '<path>' instead of the current working 516 directory. When multiple `-C` options are given, each subsequent 517 non-absolute `-C <path>` is interpreted relative to the preceding `-C 518 <path>`. 519+ 520This option affects options that expect path name like `--git-dir` and 521`--work-tree` in that their interpretations of the path names would be 522made relative to the working directory caused by the `-C` option. For 523example the following invocations are equivalent: 524 525 git --git-dir=a.git --work-tree=b -C c status 526 git --git-dir=c/a.git --work-tree=c/b status 527 528-c <name>=<value>:: 529 Pass a configuration parameter to the command. The value 530 given will override values from configuration files. 531 The <name> is expected in the same format as listed by 532 'git config' (subkeys separated by dots). 533+ 534Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets 535`foo.bar` to the boolean true value (just like `[foo]bar` would in a 536config file). Including the equals but with an empty value (like `git -c 537foo.bar= ...`) sets `foo.bar` to the empty string. 538 539--exec-path[=<path>]:: 540 Path to wherever your core Git programs are installed. 541 This can also be controlled by setting the GIT_EXEC_PATH 542 environment variable. If no path is given, 'git' will print 543 the current setting and then exit. 544 545--html-path:: 546 Print the path, without trailing slash, where Git's HTML 547 documentation is installed and exit. 548 549--man-path:: 550 Print the manpath (see `man(1)`) for the man pages for 551 this version of Git and exit. 552 553--info-path:: 554 Print the path where the Info files documenting this 555 version of Git are installed and exit. 556 557-p:: 558--paginate:: 559 Pipe all output into 'less' (or if set, $PAGER) if standard 560 output is a terminal. This overrides the `pager.<cmd>` 561 configuration options (see the "Configuration Mechanism" section 562 below). 563 564--no-pager:: 565 Do not pipe Git output into a pager. 566 567--git-dir=<path>:: 568 Set the path to the repository. This can also be controlled by 569 setting the GIT_DIR environment variable. It can be an absolute 570 path or relative path to current working directory. 571 572--work-tree=<path>:: 573 Set the path to the working tree. It can be an absolute path 574 or a path relative to the current working directory. 575 This can also be controlled by setting the GIT_WORK_TREE 576 environment variable and the core.worktree configuration 577 variable (see core.worktree in linkgit:git-config[1] for a 578 more detailed discussion). 579 580--namespace=<path>:: 581 Set the Git namespace. See linkgit:gitnamespaces[7] for more 582 details. Equivalent to setting the `GIT_NAMESPACE` environment 583 variable. 584 585--bare:: 586 Treat the repository as a bare repository. If GIT_DIR 587 environment is not set, it is set to the current working 588 directory. 589 590--no-replace-objects:: 591 Do not use replacement refs to replace Git objects. See 592 linkgit:git-replace[1] for more information. 593 594--literal-pathspecs:: 595 Treat pathspecs literally (i.e. no globbing, no pathspec magic). 596 This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment 597 variable to `1`. 598 599--glob-pathspecs:: 600 Add "glob" magic to all pathspec. This is equivalent to setting 601 the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling 602 globbing on individual pathspecs can be done using pathspec 603 magic ":(literal)" 604 605--noglob-pathspecs:: 606 Add "literal" magic to all pathspec. This is equivalent to setting 607 the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling 608 globbing on individual pathspecs can be done using pathspec 609 magic ":(glob)" 610 611--icase-pathspecs:: 612 Add "icase" magic to all pathspec. This is equivalent to setting 613 the `GIT_ICASE_PATHSPECS` environment variable to `1`. 614 615GIT COMMANDS 616------------ 617 618We divide Git into high level ("porcelain") commands and low level 619("plumbing") commands. 620 621High-level commands (porcelain) 622------------------------------- 623 624We separate the porcelain commands into the main commands and some 625ancillary user utilities. 626 627Main porcelain commands 628~~~~~~~~~~~~~~~~~~~~~~~ 629 630include::cmds-mainporcelain.txt[] 631 632Ancillary Commands 633~~~~~~~~~~~~~~~~~~ 634Manipulators: 635 636include::cmds-ancillarymanipulators.txt[] 637 638Interrogators: 639 640include::cmds-ancillaryinterrogators.txt[] 641 642 643Interacting with Others 644~~~~~~~~~~~~~~~~~~~~~~~ 645 646These commands are to interact with foreign SCM and with other 647people via patch over e-mail. 648 649include::cmds-foreignscminterface.txt[] 650 651 652Low-level commands (plumbing) 653----------------------------- 654 655Although Git includes its 656own porcelain layer, its low-level commands are sufficient to support 657development of alternative porcelains. Developers of such porcelains 658might start by reading about linkgit:git-update-index[1] and 659linkgit:git-read-tree[1]. 660 661The interface (input, output, set of options and the semantics) 662to these low-level commands are meant to be a lot more stable 663than Porcelain level commands, because these commands are 664primarily for scripted use. The interface to Porcelain commands 665on the other hand are subject to change in order to improve the 666end user experience. 667 668The following description divides 669the low-level commands into commands that manipulate objects (in 670the repository, index, and working tree), commands that interrogate and 671compare objects, and commands that move objects and references between 672repositories. 673 674 675Manipulation commands 676~~~~~~~~~~~~~~~~~~~~~ 677 678include::cmds-plumbingmanipulators.txt[] 679 680 681Interrogation commands 682~~~~~~~~~~~~~~~~~~~~~~ 683 684include::cmds-plumbinginterrogators.txt[] 685 686In general, the interrogate commands do not touch the files in 687the working tree. 688 689 690Synching repositories 691~~~~~~~~~~~~~~~~~~~~~ 692 693include::cmds-synchingrepositories.txt[] 694 695The following are helper commands used by the above; end users 696typically do not use them directly. 697 698include::cmds-synchelpers.txt[] 699 700 701Internal helper commands 702~~~~~~~~~~~~~~~~~~~~~~~~ 703 704These are internal helper commands used by other commands; end 705users typically do not use them directly. 706 707include::cmds-purehelpers.txt[] 708 709 710Configuration Mechanism 711----------------------- 712 713Git uses a simple text format to store customizations that are per 714repository and are per user. Such a configuration file may look 715like this: 716 717------------ 718# 719# A '#' or ';' character indicates a comment. 720# 721 722; core variables 723[core] 724 ; Don't trust file modes 725 filemode = false 726 727; user identity 728[user] 729 name = "Junio C Hamano" 730 email = "gitster@pobox.com" 731 732------------ 733 734Various commands read from the configuration file and adjust 735their operation accordingly. See linkgit:git-config[1] for a 736list and more details about the configuration mechanism. 737 738 739Identifier Terminology 740---------------------- 741<object>:: 742 Indicates the object name for any type of object. 743 744<blob>:: 745 Indicates a blob object name. 746 747<tree>:: 748 Indicates a tree object name. 749 750<commit>:: 751 Indicates a commit object name. 752 753<tree-ish>:: 754 Indicates a tree, commit or tag object name. A 755 command that takes a <tree-ish> argument ultimately wants to 756 operate on a <tree> object but automatically dereferences 757 <commit> and <tag> objects that point at a <tree>. 758 759<commit-ish>:: 760 Indicates a commit or tag object name. A 761 command that takes a <commit-ish> argument ultimately wants to 762 operate on a <commit> object but automatically dereferences 763 <tag> objects that point at a <commit>. 764 765<type>:: 766 Indicates that an object type is required. 767 Currently one of: `blob`, `tree`, `commit`, or `tag`. 768 769<file>:: 770 Indicates a filename - almost always relative to the 771 root of the tree structure `GIT_INDEX_FILE` describes. 772 773Symbolic Identifiers 774-------------------- 775Any Git command accepting any <object> can also use the following 776symbolic notation: 777 778HEAD:: 779 indicates the head of the current branch. 780 781<tag>:: 782 a valid tag 'name' 783 (i.e. a `refs/tags/<tag>` reference). 784 785<head>:: 786 a valid head 'name' 787 (i.e. a `refs/heads/<head>` reference). 788 789For a more complete list of ways to spell object names, see 790"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7]. 791 792 793File/Directory Structure 794------------------------ 795 796Please see the linkgit:gitrepository-layout[5] document. 797 798Read linkgit:githooks[5] for more details about each hook. 799 800Higher level SCMs may provide and manage additional information in the 801`$GIT_DIR`. 802 803 804Terminology 805----------- 806Please see linkgit:gitglossary[7]. 807 808 809Environment Variables 810--------------------- 811Various Git commands use the following environment variables: 812 813The Git Repository 814~~~~~~~~~~~~~~~~~~ 815These environment variables apply to 'all' core Git commands. Nb: it 816is worth noting that they may be used/overridden by SCMS sitting above 817Git so take care if using a foreign front-end. 818 819'GIT_INDEX_FILE':: 820 This environment allows the specification of an alternate 821 index file. If not specified, the default of `$GIT_DIR/index` 822 is used. 823 824'GIT_INDEX_VERSION':: 825 This environment variable allows the specification of an index 826 version for new repositories. It won't affect existing index 827 files. By default index file version 2 or 3 is used. See 828 linkgit:git-update-index[1] for more information. 829 830'GIT_OBJECT_DIRECTORY':: 831 If the object storage directory is specified via this 832 environment variable then the sha1 directories are created 833 underneath - otherwise the default `$GIT_DIR/objects` 834 directory is used. 835 836'GIT_ALTERNATE_OBJECT_DIRECTORIES':: 837 Due to the immutable nature of Git objects, old objects can be 838 archived into shared, read-only directories. This variable 839 specifies a ":" separated (on Windows ";" separated) list 840 of Git object directories which can be used to search for Git 841 objects. New objects will not be written to these directories. 842 843'GIT_DIR':: 844 If the 'GIT_DIR' environment variable is set then it 845 specifies a path to use instead of the default `.git` 846 for the base of the repository. 847 The '--git-dir' command-line option also sets this value. 848 849'GIT_WORK_TREE':: 850 Set the path to the root of the working tree. 851 This can also be controlled by the '--work-tree' command-line 852 option and the core.worktree configuration variable. 853 854'GIT_NAMESPACE':: 855 Set the Git namespace; see linkgit:gitnamespaces[7] for details. 856 The '--namespace' command-line option also sets this value. 857 858'GIT_CEILING_DIRECTORIES':: 859 This should be a colon-separated list of absolute paths. If 860 set, it is a list of directories that Git should not chdir up 861 into while looking for a repository directory (useful for 862 excluding slow-loading network directories). It will not 863 exclude the current working directory or a GIT_DIR set on the 864 command line or in the environment. Normally, Git has to read 865 the entries in this list and resolve any symlink that 866 might be present in order to compare them with the current 867 directory. However, if even this access is slow, you 868 can add an empty entry to the list to tell Git that the 869 subsequent entries are not symlinks and needn't be resolved; 870 e.g., 871 'GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink'. 872 873'GIT_DISCOVERY_ACROSS_FILESYSTEM':: 874 When run in a directory that does not have ".git" repository 875 directory, Git tries to find such a directory in the parent 876 directories to find the top of the working tree, but by default it 877 does not cross filesystem boundaries. This environment variable 878 can be set to true to tell Git not to stop at filesystem 879 boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect 880 an explicit repository directory set via 'GIT_DIR' or on the 881 command line. 882 883'GIT_COMMON_DIR':: 884 If this variable is set to a path, non-worktree files that are 885 normally in $GIT_DIR will be taken from this path 886 instead. Worktree-specific files such as HEAD or index are 887 taken from $GIT_DIR. See linkgit:gitrepository-layout[5] and 888 linkgit:git-worktree[1] for 889 details. This variable has lower precedence than other path 890 variables such as GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY... 891 892Git Commits 893~~~~~~~~~~~ 894'GIT_AUTHOR_NAME':: 895'GIT_AUTHOR_EMAIL':: 896'GIT_AUTHOR_DATE':: 897'GIT_COMMITTER_NAME':: 898'GIT_COMMITTER_EMAIL':: 899'GIT_COMMITTER_DATE':: 900'EMAIL':: 901 see linkgit:git-commit-tree[1] 902 903Git Diffs 904~~~~~~~~~ 905'GIT_DIFF_OPTS':: 906 Only valid setting is "--unified=??" or "-u??" to set the 907 number of context lines shown when a unified diff is created. 908 This takes precedence over any "-U" or "--unified" option 909 value passed on the Git diff command line. 910 911'GIT_EXTERNAL_DIFF':: 912 When the environment variable 'GIT_EXTERNAL_DIFF' is set, the 913 program named by it is called, instead of the diff invocation 914 described above. For a path that is added, removed, or modified, 915 'GIT_EXTERNAL_DIFF' is called with 7 parameters: 916 917 path old-file old-hex old-mode new-file new-hex new-mode 918+ 919where: 920 921 <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the 922 contents of <old|new>, 923 <old|new>-hex:: are the 40-hexdigit SHA-1 hashes, 924 <old|new>-mode:: are the octal representation of the file modes. 925+ 926The file parameters can point at the user's working file 927(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file` 928when a new file is added), or a temporary file (e.g. `old-file` in the 929index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the 930temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits. 931+ 932For a path that is unmerged, 'GIT_EXTERNAL_DIFF' is called with 1 933parameter, <path>. 934+ 935For each path 'GIT_EXTERNAL_DIFF' is called, two environment variables, 936'GIT_DIFF_PATH_COUNTER' and 'GIT_DIFF_PATH_TOTAL' are set. 937 938'GIT_DIFF_PATH_COUNTER':: 939 A 1-based counter incremented by one for every path. 940 941'GIT_DIFF_PATH_TOTAL':: 942 The total number of paths. 943 944other 945~~~~~ 946'GIT_MERGE_VERBOSITY':: 947 A number controlling the amount of output shown by 948 the recursive merge strategy. Overrides merge.verbosity. 949 See linkgit:git-merge[1] 950 951'GIT_PAGER':: 952 This environment variable overrides `$PAGER`. If it is set 953 to an empty string or to the value "cat", Git will not launch 954 a pager. See also the `core.pager` option in 955 linkgit:git-config[1]. 956 957'GIT_EDITOR':: 958 This environment variable overrides `$EDITOR` and `$VISUAL`. 959 It is used by several Git commands when, on interactive mode, 960 an editor is to be launched. See also linkgit:git-var[1] 961 and the `core.editor` option in linkgit:git-config[1]. 962 963'GIT_SSH':: 964'GIT_SSH_COMMAND':: 965 If either of these environment variables is set then 'git fetch' 966 and 'git push' will use the specified command instead of 'ssh' 967 when they need to connect to a remote system. 968 The command will be given exactly two or four arguments: the 969 'username@host' (or just 'host') from the URL and the shell 970 command to execute on that remote system, optionally preceded by 971 '-p' (literally) and the 'port' from the URL when it specifies 972 something other than the default SSH port. 973+ 974`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted 975by the shell, which allows additional arguments to be included. 976`$GIT_SSH` on the other hand must be just the path to a program 977(which can be a wrapper shell script, if additional arguments are 978needed). 979+ 980Usually it is easier to configure any desired options through your 981personal `.ssh/config` file. Please consult your ssh documentation 982for further details. 983 984'GIT_ASKPASS':: 985 If this environment variable is set, then Git commands which need to 986 acquire passwords or passphrases (e.g. for HTTP or IMAP authentication) 987 will call this program with a suitable prompt as command-line argument 988 and read the password from its STDOUT. See also the 'core.askPass' 989 option in linkgit:git-config[1]. 990 991'GIT_TERMINAL_PROMPT':: 992 If this environment variable is set to `0`, git will not prompt 993 on the terminal (e.g., when asking for HTTP authentication). 994 995'GIT_CONFIG_NOSYSTEM':: 996 Whether to skip reading settings from the system-wide 997 `$(prefix)/etc/gitconfig` file. This environment variable can 998 be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a 999 predictable environment for a picky script, or you can set it1000 temporarily to avoid using a buggy `/etc/gitconfig` file while1001 waiting for someone with sufficient permissions to fix it.10021003'GIT_FLUSH'::1004 If this environment variable is set to "1", then commands such1005 as 'git blame' (in incremental mode), 'git rev-list', 'git log',1006 'git check-attr' and 'git check-ignore' will1007 force a flush of the output stream after each record have been1008 flushed. If this1009 variable is set to "0", the output of these commands will be done1010 using completely buffered I/O. If this environment variable is1011 not set, Git will choose buffered or record-oriented flushing1012 based on whether stdout appears to be redirected to a file or not.10131014'GIT_TRACE'::1015 Enables general trace messages, e.g. alias expansion, built-in1016 command execution and external command execution.1017+1018If this variable is set to "1", "2" or "true" (comparison1019is case insensitive), trace messages will be printed to1020stderr.1021+1022If the variable is set to an integer value greater than 21023and lower than 10 (strictly) then Git will interpret this1024value as an open file descriptor and will try to write the1025trace messages into this file descriptor.1026+1027Alternatively, if the variable is set to an absolute path1028(starting with a '/' character), Git will interpret this1029as a file path and will try to write the trace messages1030into it.1031+1032Unsetting the variable, or setting it to empty, "0" or1033"false" (case insensitive) disables trace messages.10341035'GIT_TRACE_PACK_ACCESS'::1036 Enables trace messages for all accesses to any packs. For each1037 access, the pack file name and an offset in the pack is1038 recorded. This may be helpful for troubleshooting some1039 pack-related performance problems.1040 See 'GIT_TRACE' for available trace output options.10411042'GIT_TRACE_PACKET'::1043 Enables trace messages for all packets coming in or out of a1044 given program. This can help with debugging object negotiation1045 or other protocol issues. Tracing is turned off at a packet1046 starting with "PACK" (but see 'GIT_TRACE_PACKFILE' below).1047 See 'GIT_TRACE' for available trace output options.10481049'GIT_TRACE_PACKFILE'::1050 Enables tracing of packfiles sent or received by a1051 given program. Unlike other trace output, this trace is1052 verbatim: no headers, and no quoting of binary data. You almost1053 certainly want to direct into a file (e.g.,1054 `GIT_TRACE_PACKFILE=/tmp/my.pack`) rather than displaying it on1055 the terminal or mixing it with other trace output.1056+1057Note that this is currently only implemented for the client side1058of clones and fetches.10591060'GIT_TRACE_PERFORMANCE'::1061 Enables performance related trace messages, e.g. total execution1062 time of each Git command.1063 See 'GIT_TRACE' for available trace output options.10641065'GIT_TRACE_SETUP'::1066 Enables trace messages printing the .git, working tree and current1067 working directory after Git has completed its setup phase.1068 See 'GIT_TRACE' for available trace output options.10691070'GIT_TRACE_SHALLOW'::1071 Enables trace messages that can help debugging fetching /1072 cloning of shallow repositories.1073 See 'GIT_TRACE' for available trace output options.10741075'GIT_LITERAL_PATHSPECS'::1076 Setting this variable to `1` will cause Git to treat all1077 pathspecs literally, rather than as glob patterns. For example,1078 running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search1079 for commits that touch the path `*.c`, not any paths that the1080 glob `*.c` matches. You might want this if you are feeding1081 literal paths to Git (e.g., paths previously given to you by1082 `git ls-tree`, `--raw` diff output, etc).10831084'GIT_GLOB_PATHSPECS'::1085 Setting this variable to `1` will cause Git to treat all1086 pathspecs as glob patterns (aka "glob" magic).10871088'GIT_NOGLOB_PATHSPECS'::1089 Setting this variable to `1` will cause Git to treat all1090 pathspecs as literal (aka "literal" magic).10911092'GIT_ICASE_PATHSPECS'::1093 Setting this variable to `1` will cause Git to treat all1094 pathspecs as case-insensitive.10951096'GIT_REFLOG_ACTION'::1097 When a ref is updated, reflog entries are created to keep1098 track of the reason why the ref was updated (which is1099 typically the name of the high-level command that updated1100 the ref), in addition to the old and new values of the ref.1101 A scripted Porcelain command can use set_reflog_action1102 helper function in `git-sh-setup` to set its name to this1103 variable when it is invoked as the top level command by the1104 end user, to be recorded in the body of the reflog.11051106'GIT_REF_PARANOIA'::1107 If set to `1`, include broken or badly named refs when iterating1108 over lists of refs. In a normal, non-corrupted repository, this1109 does nothing. However, enabling it may help git to detect and1110 abort some operations in the presence of broken refs. Git sets1111 this variable automatically when performing destructive1112 operations like linkgit:git-prune[1]. You should not need to set1113 it yourself unless you want to be paranoid about making sure1114 an operation has touched every ref (e.g., because you are1115 cloning a repository to make a backup).11161117'GIT_ALLOW_PROTOCOL'::1118 If set, provide a colon-separated list of protocols which are1119 allowed to be used with fetch/push/clone. This is useful to1120 restrict recursive submodule initialization from an untrusted1121 repository. Any protocol not mentioned will be disallowed (i.e.,1122 this is a whitelist, not a blacklist). If the variable is not1123 set at all, all protocols are enabled. The protocol names1124 currently used by git are:11251126 - `file`: any local file-based path (including `file://` URLs,1127 or local paths)11281129 - `git`: the anonymous git protocol over a direct TCP1130 connection (or proxy, if configured)11311132 - `ssh`: git over ssh (including `host:path` syntax,1133 `git+ssh://`, etc).11341135 - `rsync`: git over rsync11361137 - `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.
