  19DESCRIPTION
  20-----------
  21Git is a fast, scalable, distributed revision control system with an
  22unusually rich command set that provides both high-level operations
  23and full access to internals.
  24
  25See linkgit:gittutorial[7] to get started, then see
  26linkgit:giteveryday[7] for a useful minimum set of
  27commands.  The link:user-manual.html[Git User's Manual] has a more
  28in-depth introduction.
  29
  30After you mastered the basic concepts, you can come back to this
  31page to learn what commands Git offers.  You can learn more about
  32individual Git commands with "git help command".  linkgit:gitcli[7]
  33manual page gives you an overview of the command-line command syntax.
  34
  35A formatted and hyperlinked copy of the latest Git documentation
  36can be viewed at `https://git.github.io/htmldocs/git.html`.

 516============
 517
 518endif::stalenotes[]
 519
 520OPTIONS
 521-------
 522--version::
 523        Prints the Git suite version that the 'git' program came from.
 524
 525--help::
 526        Prints the synopsis and a list of the most commonly used
 527        commands. If the option `--all` or `-a` is given then all
 528        available commands are printed. If a Git command is named this
 529        option will bring up the manual page for that command.
 530+
 531Other options are available to control how the manual page is
 532displayed. See linkgit:git-help[1] for more information,
 533because `git --help ...` is converted internally into `git
 534help ...`.
 535
 536-C <path>::
 537        Run as if git was started in '<path>' instead of the current working
 538        directory.  When multiple `-C` options are given, each subsequent
 539        non-absolute `-C <path>` is interpreted relative to the preceding `-C
 540        <path>`.
 541+
 542This option affects options that expect path name like `--git-dir` and
 543`--work-tree` in that their interpretations of the path names would be
 544made relative to the working directory caused by the `-C` option. For
 545example the following invocations are equivalent:
 546
 547    git --git-dir=a.git --work-tree=b -C c status
 548    git --git-dir=c/a.git --work-tree=c/b status
 549
 550-c <name>=<value>::
 551        Pass a configuration parameter to the command. The value
 552        given will override values from configuration files.
 553        The <name> is expected in the same format as listed by
 554        'git config' (subkeys separated by dots).
 555+
 556Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets
 557`foo.bar` to the boolean true value (just like `[foo]bar` would in a
 558config file). Including the equals but with an empty value (like `git -c
 559foo.bar= ...`) sets `foo.bar` to the empty string.
 560
 561--exec-path[=<path>]::
 562        Path to wherever your core Git programs are installed.
 563        This can also be controlled by setting the GIT_EXEC_PATH
 564        environment variable. If no path is given, 'git' will print
 565        the current setting and then exit.
 566
 567--html-path::
 568        Print the path, without trailing slash, where Git's HTML
 569        documentation is installed and exit.
 570
 571--man-path::
 572        Print the manpath (see `man(1)`) for the man pages for
 573        this version of Git and exit.
 574
 575--info-path::
 576        Print the path where the Info files documenting this
 577        version of Git are installed and exit.
 578
 579-p::
 580--paginate::
 581        Pipe all output into 'less' (or if set, $PAGER) if standard
 582        output is a terminal.  This overrides the `pager.<cmd>`
 583        configuration options (see the "Configuration Mechanism" section
 584        below).
 585
 586--no-pager::
 587        Do not pipe Git output into a pager.
 588
 589--git-dir=<path>::
 590        Set the path to the repository. This can also be controlled by
 591        setting the `GIT_DIR` environment variable. It can be an absolute
 592        path or relative path to current working directory.
 593
 594--work-tree=<path>::
 595        Set the path to the working tree. It can be an absolute path
 596        or a path relative to the current working directory.
 597        This can also be controlled by setting the GIT_WORK_TREE
 598        environment variable and the core.worktree configuration
 599        variable (see core.worktree in linkgit:git-config[1] for a
 600        more detailed discussion).
 601
 602--namespace=<path>::
 603        Set the Git namespace.  See linkgit:gitnamespaces[7] for more
 604        details.  Equivalent to setting the `GIT_NAMESPACE` environment
 605        variable.
 606
 607--super-prefix=<path>::
 608        Currently for internal use only.  Set a prefix which gives a path from
 609        above a repository down to its root.  One use is to give submodules
 610        context about the superproject that invoked it.
 611
 612--bare::
 613        Treat the repository as a bare repository.  If GIT_DIR
 614        environment is not set, it is set to the current working
 615        directory.
 616
 617--no-replace-objects::
 618        Do not use replacement refs to replace Git objects. See
 619        linkgit:git-replace[1] for more information.
 620
 621--literal-pathspecs::
 622        Treat pathspecs literally (i.e. no globbing, no pathspec magic).
 623        This is equivalent to setting the `GIT_LITERAL_PATHSPECS` environment
 624        variable to `1`.
 625
 626--glob-pathspecs::
 627        Add "glob" magic to all pathspec. This is equivalent to setting
 628        the `GIT_GLOB_PATHSPECS` environment variable to `1`. Disabling
 629        globbing on individual pathspecs can be done using pathspec
 630        magic ":(literal)"
 631
 632--noglob-pathspecs::
 633        Add "literal" magic to all pathspec. This is equivalent to setting
 634        the `GIT_NOGLOB_PATHSPECS` environment variable to `1`. Enabling
 635        globbing on individual pathspecs can be done using pathspec
 636        magic ":(glob)"
 637
 638--icase-pathspecs::
 639        Add "icase" magic to all pathspec. This is equivalent to setting
 640        the `GIT_ICASE_PATHSPECS` environment variable to `1`.
 641
 642GIT COMMANDS
 643------------
 644
 645We divide Git into high level ("porcelain") commands and low level
 646("plumbing") commands.
 647
 648High-level commands (porcelain)
 649-------------------------------
 650
 651We separate the porcelain commands into the main commands and some
 652ancillary user utilities.
 653
 654Main porcelain commands
 655~~~~~~~~~~~~~~~~~~~~~~~
 656
 657include::cmds-mainporcelain.txt[]
 658
 659Ancillary Commands
 660~~~~~~~~~~~~~~~~~~
 661Manipulators:
 662
 663include::cmds-ancillarymanipulators.txt[]
 664
 665Interrogators:
 666
 667include::cmds-ancillaryinterrogators.txt[]
 668
 669
 670Interacting with Others
 671~~~~~~~~~~~~~~~~~~~~~~~
 672
 673These commands are to interact with foreign SCM and with other
 674people via patch over e-mail.
 675
 676include::cmds-foreignscminterface.txt[]
 677
 678
 679Low-level commands (plumbing)
 680-----------------------------
 681
 682Although Git includes its
 683own porcelain layer, its low-level commands are sufficient to support
 684development of alternative porcelains.  Developers of such porcelains
 685might start by reading about linkgit:git-update-index[1] and
 686linkgit:git-read-tree[1].
 687
 688The interface (input, output, set of options and the semantics)
 689to these low-level commands are meant to be a lot more stable
 690than Porcelain level commands, because these commands are
 691primarily for scripted use.  The interface to Porcelain commands
 692on the other hand are subject to change in order to improve the
 693end user experience.
 694
 695The following description divides
 696the low-level commands into commands that manipulate objects (in
 697the repository, index, and working tree), commands that interrogate and
 698compare objects, and commands that move objects and references between
 699repositories.
 700
 701
 702Manipulation commands
 703~~~~~~~~~~~~~~~~~~~~~
 704
 705include::cmds-plumbingmanipulators.txt[]
 706
 707
 708Interrogation commands
 709~~~~~~~~~~~~~~~~~~~~~~
 710
 711include::cmds-plumbinginterrogators.txt[]
 712
 713In general, the interrogate commands do not touch the files in
 714the working tree.
 715
 716
 717Synching repositories
 718~~~~~~~~~~~~~~~~~~~~~
 719
 720include::cmds-synchingrepositories.txt[]
 721
 722The following are helper commands used by the above; end users
 723typically do not use them directly.
 724
 725include::cmds-synchelpers.txt[]
 726
 727
 728Internal helper commands
 729~~~~~~~~~~~~~~~~~~~~~~~~
 730
 731These are internal helper commands used by other commands; end
 732users typically do not use them directly.
 733
 734include::cmds-purehelpers.txt[]
 735
 736
 737Configuration Mechanism
 738-----------------------
 739
 740Git uses a simple text format to store customizations that are per
 741repository and are per user.  Such a configuration file may look
 742like this:
 743
 744------------
 745#
 746# A '#' or ';' character indicates a comment.
 747#
 748
 749; core variables
 750[core]
 751        ; Don't trust file modes
 752        filemode = false
 753
 754; user identity
 755[user]
 756        name = "Junio C Hamano"
 757        email = "gitster@pobox.com"
 758
 759------------
 760
 761Various commands read from the configuration file and adjust
 762their operation accordingly.  See linkgit:git-config[1] for a
 763list and more details about the configuration mechanism.
 764
 765
 766Identifier Terminology
 767----------------------
 768<object>::
 769        Indicates the object name for any type of object.
 770
 771<blob>::
 772        Indicates a blob object name.
 773
 774<tree>::
 775        Indicates a tree object name.
 776
 777<commit>::
 778        Indicates a commit object name.
 779
 780<tree-ish>::
 781        Indicates a tree, commit or tag object name.  A
 782        command that takes a <tree-ish> argument ultimately wants to
 783        operate on a <tree> object but automatically dereferences
 784        <commit> and <tag> objects that point at a <tree>.
 785
 786<commit-ish>::
 787        Indicates a commit or tag object name.  A
 788        command that takes a <commit-ish> argument ultimately wants to
 789        operate on a <commit> object but automatically dereferences
 790        <tag> objects that point at a <commit>.
 791
 792<type>::
 793        Indicates that an object type is required.
 794        Currently one of: `blob`, `tree`, `commit`, or `tag`.
 795
 796<file>::
 797        Indicates a filename - almost always relative to the
 798        root of the tree structure `GIT_INDEX_FILE` describes.
 799
 800Symbolic Identifiers
 801--------------------
 802Any Git command accepting any <object> can also use the following
 803symbolic notation:
 804
 805HEAD::
 806        indicates the head of the current branch.
 807
 808<tag>::
 809        a valid tag 'name'
 810        (i.e. a `refs/tags/<tag>` reference).
 811
 812<head>::
 813        a valid head 'name'
 814        (i.e. a `refs/heads/<head>` reference).
 815
 816For a more complete list of ways to spell object names, see
 817"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7].
 818
 819
 820File/Directory Structure
 821------------------------
 822
 823Please see the linkgit:gitrepository-layout[5] document.
 824
 825Read linkgit:githooks[5] for more details about each hook.
 826
 827Higher level SCMs may provide and manage additional information in the
 828`$GIT_DIR`.
 829
 830
 831Terminology
 832-----------
 833Please see linkgit:gitglossary[7].
 834
 835
 836Environment Variables
 837---------------------
 838Various Git commands use the following environment variables:
 839
 840The Git Repository
 841~~~~~~~~~~~~~~~~~~
 842These environment variables apply to 'all' core Git commands. Nb: it
 843is worth noting that they may be used/overridden by SCMS sitting above
 844Git so take care if using a foreign front-end.
 845
 846`GIT_INDEX_FILE`::
 847        This environment allows the specification of an alternate
 848        index file. If not specified, the default of `$GIT_DIR/index`
 849        is used.
 850
 851`GIT_INDEX_VERSION`::
 852        This environment variable allows the specification of an index
 853        version for new repositories.  It won't affect existing index
 854        files.  By default index file version 2 or 3 is used. See
 855        linkgit:git-update-index[1] for more information.
 856
 857`GIT_OBJECT_DIRECTORY`::
 858        If the object storage directory is specified via this
 859        environment variable then the sha1 directories are created
 860        underneath - otherwise the default `$GIT_DIR/objects`
 861        directory is used.
 862
 863`GIT_ALTERNATE_OBJECT_DIRECTORIES`::
 864        Due to the immutable nature of Git objects, old objects can be
 865        archived into shared, read-only directories. This variable
 866        specifies a ":" separated (on Windows ";" separated) list
 867        of Git object directories which can be used to search for Git
 868        objects. New objects will not be written to these directories.
 869
 870`GIT_DIR`::
 871        If the `GIT_DIR` environment variable is set then it
 872        specifies a path to use instead of the default `.git`
 873        for the base of the repository.
 874        The `--git-dir` command-line option also sets this value.
 875
 876`GIT_WORK_TREE`::
 877        Set the path to the root of the working tree.
 878        This can also be controlled by the `--work-tree` command-line
 879        option and the core.worktree configuration variable.
 880
 881`GIT_NAMESPACE`::
 882        Set the Git namespace; see linkgit:gitnamespaces[7] for details.
 883        The `--namespace` command-line option also sets this value.
 884
 885`GIT_CEILING_DIRECTORIES`::
 886        This should be a colon-separated list of absolute paths.  If
 887        set, it is a list of directories that Git should not chdir up
 888        into while looking for a repository directory (useful for
 889        excluding slow-loading network directories).  It will not
 890        exclude the current working directory or a GIT_DIR set on the
 891        command line or in the environment.  Normally, Git has to read
 892        the entries in this list and resolve any symlink that
 893        might be present in order to compare them with the current
 894        directory.  However, if even this access is slow, you
 895        can add an empty entry to the list to tell Git that the
 896        subsequent entries are not symlinks and needn't be resolved;
 897        e.g.,
 898        `GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink`.
 899
 900`GIT_DISCOVERY_ACROSS_FILESYSTEM`::
 901        When run in a directory that does not have ".git" repository
 902        directory, Git tries to find such a directory in the parent
 903        directories to find the top of the working tree, but by default it
 904        does not cross filesystem boundaries.  This environment variable
 905        can be set to true to tell Git not to stop at filesystem
 906        boundaries.  Like `GIT_CEILING_DIRECTORIES`, this will not affect
 907        an explicit repository directory set via `GIT_DIR` or on the
 908        command line.
 909
 910`GIT_COMMON_DIR`::
 911        If this variable is set to a path, non-worktree files that are
 912        normally in $GIT_DIR will be taken from this path
 913        instead. Worktree-specific files such as HEAD or index are
 914        taken from $GIT_DIR. See linkgit:gitrepository-layout[5] and
 915        linkgit:git-worktree[1] for
 916        details. This variable has lower precedence than other path
 917        variables such as GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY...
 918
 919Git Commits
 920~~~~~~~~~~~
 921`GIT_AUTHOR_NAME`::
 922`GIT_AUTHOR_EMAIL`::

 924`GIT_COMMITTER_NAME`::
 925`GIT_COMMITTER_EMAIL`::
 926`GIT_COMMITTER_DATE`::

 928        see linkgit:git-commit-tree[1]
 929
 930Git Diffs
 931~~~~~~~~~
 932`GIT_DIFF_OPTS`::
 933        Only valid setting is "--unified=??" or "-u??" to set the
 934        number of context lines shown when a unified diff is created.
 935        This takes precedence over any "-U" or "--unified" option
 936        value passed on the Git diff command line.
 937
 938`GIT_EXTERNAL_DIFF`::
 939        When the environment variable `GIT_EXTERNAL_DIFF` is set, the
 940        program named by it is called, instead of the diff invocation
 941        described above.  For a path that is added, removed, or modified,
 942        `GIT_EXTERNAL_DIFF` is called with 7 parameters:
 943
 944        path old-file old-hex old-mode new-file new-hex new-mode
 945+
 946where:
 947
 948        <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the
 949                         contents of <old|new>,
 950        <old|new>-hex:: are the 40-hexdigit SHA-1 hashes,
 951        <old|new>-mode:: are the octal representation of the file modes.
 952+
 953The file parameters can point at the user's working file
 954(e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file`
 955when a new file is added), or a temporary file (e.g. `old-file` in the
 956index).  `GIT_EXTERNAL_DIFF` should not worry about unlinking the
 957temporary file --- it is removed when `GIT_EXTERNAL_DIFF` exits.
 958+
 959For a path that is unmerged, `GIT_EXTERNAL_DIFF` is called with 1
 960parameter, <path>.
 961+
 962For each path `GIT_EXTERNAL_DIFF` is called, two environment variables,
 963`GIT_DIFF_PATH_COUNTER` and `GIT_DIFF_PATH_TOTAL` are set.
 964
 965`GIT_DIFF_PATH_COUNTER`::
 966        A 1-based counter incremented by one for every path.
 967
 968`GIT_DIFF_PATH_TOTAL`::
 969        The total number of paths.
 970
 971other
 972~~~~~
 973`GIT_MERGE_VERBOSITY`::
 974        A number controlling the amount of output shown by
 975        the recursive merge strategy.  Overrides merge.verbosity.
 976        See linkgit:git-merge[1]
 977
 978`GIT_PAGER`::
 979        This environment variable overrides `$PAGER`. If it is set
 980        to an empty string or to the value "cat", Git will not launch
 981        a pager.  See also the `core.pager` option in
 982        linkgit:git-config[1].
 983
 984`GIT_EDITOR`::
 985        This environment variable overrides `$EDITOR` and `$VISUAL`.
 986        It is used by several Git commands when, on interactive mode,
 987        an editor is to be launched. See also linkgit:git-var[1]
 988        and the `core.editor` option in linkgit:git-config[1].
 989
 990`GIT_SSH`::
 991`GIT_SSH_COMMAND`::
 992        If either of these environment variables is set then 'git fetch'
 993        and 'git push' will use the specified command instead of 'ssh'
 994        when they need to connect to a remote system.
 995        The command will be given exactly two or four arguments: the
 996        'username@host' (or just 'host') from the URL and the shell
 997        command to execute on that remote system, optionally preceded by
 998        `-p` (literally) and the 'port' from the URL when it specifies
 999        something other than the default SSH port.
1000+
1001`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted
1002by the shell, which allows additional arguments to be included.
1003`$GIT_SSH` on the other hand must be just the path to a program
1004(which can be a wrapper shell script, if additional arguments are
1005needed).
1006+
1007Usually it is easier to configure any desired options through your
1008personal `.ssh/config` file.  Please consult your ssh documentation
1009for further details.
1010
1011`GIT_ASKPASS`::
1012        If this environment variable is set, then Git commands which need to
1013        acquire passwords or passphrases (e.g. for HTTP or IMAP authentication)
1014        will call this program with a suitable prompt as command-line argument
1015        and read the password from its STDOUT. See also the `core.askPass`
1016        option in linkgit:git-config[1].
1017
1018`GIT_TERMINAL_PROMPT`::
1019        If this environment variable is set to `0`, git will not prompt
1020        on the terminal (e.g., when asking for HTTP authentication).
1021
1022`GIT_CONFIG_NOSYSTEM`::
1023        Whether to skip reading settings from the system-wide
1024        `$(prefix)/etc/gitconfig` file.  This environment variable can
1025        be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a
1026        predictable environment for a picky script, or you can set it
1027        temporarily to avoid using a buggy `/etc/gitconfig` file while
1028        waiting for someone with sufficient permissions to fix it.
1029
1030`GIT_FLUSH`::
1031        If this environment variable is set to "1", then commands such
1032        as 'git blame' (in incremental mode), 'git rev-list', 'git log',
1033        'git check-attr' and 'git check-ignore' will
1034        force a flush of the output stream after each record have been
1035        flushed. If this
1036        variable is set to "0", the output of these commands will be done
1037        using completely buffered I/O.   If this environment variable is
1038        not set, Git will choose buffered or record-oriented flushing
1039        based on whether stdout appears to be redirected to a file or not.
1040
1041`GIT_TRACE`::
1042        Enables general trace messages, e.g. alias expansion, built-in
1043        command execution and external command execution.
1044+
1045If this variable is set to "1", "2" or "true" (comparison
1046is case insensitive), trace messages will be printed to
1047stderr.
1048+
1049If the variable is set to an integer value greater than 2
1050and lower than 10 (strictly) then Git will interpret this
1051value as an open file descriptor and will try to write the
1052trace messages into this file descriptor.
1053+
1054Alternatively, if the variable is set to an absolute path
1055(starting with a '/' character), Git will interpret this
1056as a file path and will try to write the trace messages
1057into it.
1058+
1059Unsetting the variable, or setting it to empty, "0" or
1060"false" (case insensitive) disables trace messages.
1061
1062`GIT_TRACE_PACK_ACCESS`::
1063        Enables trace messages for all accesses to any packs. For each
1064        access, the pack file name and an offset in the pack is
1065        recorded. This may be helpful for troubleshooting some
1066        pack-related performance problems.
1067        See `GIT_TRACE` for available trace output options.
1068
1069`GIT_TRACE_PACKET`::
1070        Enables trace messages for all packets coming in or out of a
1071        given program. This can help with debugging object negotiation
1072        or other protocol issues. Tracing is turned off at a packet
1073        starting with "PACK" (but see `GIT_TRACE_PACKFILE` below).
1074        See `GIT_TRACE` for available trace output options.
1075
1076`GIT_TRACE_PACKFILE`::
1077        Enables tracing of packfiles sent or received by a
1078        given program. Unlike other trace output, this trace is
1079        verbatim: no headers, and no quoting of binary data. You almost
1080        certainly want to direct into a file (e.g.,
1081        `GIT_TRACE_PACKFILE=/tmp/my.pack`) rather than displaying it on
1082        the terminal or mixing it with other trace output.
1083+
1084Note that this is currently only implemented for the client side
1085of clones and fetches.
1086
1087`GIT_TRACE_PERFORMANCE`::
1088        Enables performance related trace messages, e.g. total execution
1089        time of each Git command.
1090        See `GIT_TRACE` for available trace output options.
1091
1092`GIT_TRACE_SETUP`::
1093        Enables trace messages printing the .git, working tree and current
1094        working directory after Git has completed its setup phase.
1095        See `GIT_TRACE` for available trace output options.
1096
1097`GIT_TRACE_SHALLOW`::
1098        Enables trace messages that can help debugging fetching /
1099        cloning of shallow repositories.
1100        See `GIT_TRACE` for available trace output options.
1101
1102`GIT_TRACE_CURL`::
1103        Enables a curl full trace dump of all incoming and outgoing data,
1104        including descriptive information, of the git transport protocol.
1105        This is similar to doing curl `--trace-ascii` on the command line.
1106        This option overrides setting the `GIT_CURL_VERBOSE` environment
1107        variable.
1108        See `GIT_TRACE` for available trace output options.
1109
1110`GIT_LITERAL_PATHSPECS`::
1111        Setting this variable to `1` will cause Git to treat all
1112        pathspecs literally, rather than as glob patterns. For example,
1113        running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search
1114        for commits that touch the path `*.c`, not any paths that the
1115        glob `*.c` matches. You might want this if you are feeding
1116        literal paths to Git (e.g., paths previously given to you by
1117        `git ls-tree`, `--raw` diff output, etc).
1118
1119`GIT_GLOB_PATHSPECS`::
1120        Setting this variable to `1` will cause Git to treat all
1121        pathspecs as glob patterns (aka "glob" magic).
1122
1123`GIT_NOGLOB_PATHSPECS`::
1124        Setting this variable to `1` will cause Git to treat all
1125        pathspecs as literal (aka "literal" magic).
1126
1127`GIT_ICASE_PATHSPECS`::
1128        Setting this variable to `1` will cause Git to treat all
1129        pathspecs as case-insensitive.
1130
1131`GIT_REFLOG_ACTION`::
1132        When a ref is updated, reflog entries are created to keep
1133        track of the reason why the ref was updated (which is
1134        typically the name of the high-level command that updated
1135        the ref), in addition to the old and new values of the ref.
1136        A scripted Porcelain command can use set_reflog_action
1137        helper function in `git-sh-setup` to set its name to this
1138        variable when it is invoked as the top level command by the
1139        end user, to be recorded in the body of the reflog.
1140
1141`GIT_REF_PARANOIA`::
1142        If set to `1`, include broken or badly named refs when iterating
1143        over lists of refs. In a normal, non-corrupted repository, this
1144        does nothing. However, enabling it may help git to detect and
1145        abort some operations in the presence of broken refs. Git sets
1146        this variable automatically when performing destructive
1147        operations like linkgit:git-prune[1]. You should not need to set
1148        it yourself unless you want to be paranoid about making sure
1149        an operation has touched every ref (e.g., because you are
1150        cloning a repository to make a backup).
1151
1152`GIT_ALLOW_PROTOCOL`::
1153        If set, provide a colon-separated list of protocols which are
1154        allowed to be used with fetch/push/clone. This is useful to
1155        restrict recursive submodule initialization from an untrusted
1156        repository. Any protocol not mentioned will be disallowed (i.e.,
1157        this is a whitelist, not a blacklist). If the variable is not
1158        set at all, all protocols are enabled.  The protocol names
1159        currently used by git are:
1160
1161          - `file`: any local file-based path (including `file://` URLs,
1162            or local paths)
1163
1164          - `git`: the anonymous git protocol over a direct TCP
1165            connection (or proxy, if configured)
1166
1167          - `ssh`: git over ssh (including `host:path` syntax,
1168            `ssh://`, etc).
1169
1170          - `http`: git over http, both "smart http" and "dumb http".
1171            Note that this does _not_ include `https`; if you want both,
1172            you should specify both as `http:https`.
1173
1174          - any external helpers are named by their protocol (e.g., use
1175            `hg` to allow the `git-remote-hg` helper)
1176

1178Discussion[[Discussion]]
1179------------------------
1180
1181More detail on the following is available from the
1182link:user-manual.html#git-concepts[Git concepts chapter of the
1183user-manual] and linkgit:gitcore-tutorial[7].
1184
1185A Git project normally consists of a working directory with a ".git"
1186subdirectory at the top level.  The .git directory contains, among other
1187things, a compressed object database representing the complete history
1188of the project, an "index" file which links that history to the current
1189contents of the working tree, and named pointers into that history such
1190as tags and branch heads.
1191
1192The object database contains objects of three main types: blobs, which
1193hold file data; trees, which point to blobs and other trees to build up
1194directory hierarchies; and commits, which each reference a single tree
1195and some number of parent commits.
1196
1197The commit, equivalent to what other systems call a "changeset" or
1198"version", represents a step in the project's history, and each parent
1199represents an immediately preceding step.  Commits with more than one
1200parent represent merges of independent lines of development.
1201
1202All objects are named by the SHA-1 hash of their contents, normally
1203written as a string of 40 hex digits.  Such names are globally unique.
1204The entire history leading up to a commit can be vouched for by signing
1205just that commit.  A fourth object type, the tag, is provided for this
1206purpose.
1207
1208When first created, objects are stored in individual files, but for
1209efficiency may later be compressed together into "pack files".
1210
1211Named pointers called refs mark interesting points in history.  A ref
1212may contain the SHA-1 name of an object or the name of another ref.  Refs
1213with names beginning `ref/head/` contain the SHA-1 name of the most
1214recent commit (or "head") of a branch under development.  SHA-1 names of
1215tags of interest are stored under `ref/tags/`.  A special ref named
1216`HEAD` contains the name of the currently checked-out branch.
1217
1218The index file is initialized with a list of all paths and, for each
1219path, a blob object and a set of attributes.  The blob object represents
1220the contents of the file as of the head of the current branch.  The
1221attributes (last modified time, size, etc.) are taken from the
1222corresponding file in the working tree.  Subsequent changes to the
1223working tree can be found by comparing these attributes.  The index may
1224be updated with new content, and new commits may be created from the
1225content stored in the index.
1226
1227The index is also capable of storing multiple entries (called "stages")
1228for a given pathname.  These stages are used to hold the various
1229unmerged version of a file when a merge is in progress.
