18 | DESCRIPTION | |
19 | ----------- | |
23091e95 BF |
20 | Git is a fast, scalable, distributed revision control system with an |
21 | unusually rich command set that provides both high-level operations | |
22 | and full access to internals. | |
23 | ||
6998e4db | 24 | See linkgit:gittutorial[7] to get started, then see |
23091e95 BF |
25 | link:everyday.html[Everyday Git] for a useful minimum set of commands, and |
26 | "man git-commandname" for documentation of each command. CVS users may | |
6998e4db JN |
27 | also want to read linkgit:gitcvs-migration[7]. See |
28 | the link:user-manual.html[Git User's Manual] for a more in-depth | |
a1dc34fa | 29 | introduction. |
cb22bc44 | 30 | |
62b4698e | 31 | The '<command>' is either a name of a Git command (see below) or an alias |
5162e697 | 32 | as defined in the configuration file (see linkgit:git-config[1]). |

386 | GIT COMMANDS |
387 | ------------ | |
9755afbd | 388 | |
23091e95 BF |
389 | We divide git into high level ("porcelain") commands and low level |
390 | ("plumbing") commands. | |
8b15e2fb | 391 | |
23091e95 BF |
392 | High-level commands (porcelain) |
393 | ------------------------------- | |
394 | ||
395 | We separate the porcelain commands into the main commands and some | |
396 | ancillary user utilities. | |
397 | ||
398 | Main porcelain commands | |

413 | |
414 | Interacting with Others | |
415 | ~~~~~~~~~~~~~~~~~~~~~~~ | |
416 | ||
417 | These commands are to interact with foreign SCM and with other | |
418 | people via patch over e-mail. | |

421 | ||

423 | Low-level commands (plumbing) |
424 | ----------------------------- | |
425 | ||
426 | Although git includes its | |
427 | own porcelain layer, its low-level commands are sufficient to support | |
428 | development of alternative porcelains. Developers of such porcelains | |
5162e697 DM |
429 | might start by reading about linkgit:git-update-index[1] and |
430 | linkgit:git-read-tree[1]. | |
b1f33d62 | 431 | |
89bf2077 JH |
432 | The interface (input, output, set of options and the semantics) |
433 | to these low-level commands are meant to be a lot more stable | |
434 | than Porcelain level commands, because these commands are | |
435 | primarily for scripted use. The interface to Porcelain commands | |
436 | on the other hand are subject to change in order to improve the | |
437 | end user experience. | |
438 | ||
439 | The following description divides | |
440 | the low-level commands into commands that manipulate objects (in | |
b1f33d62 RR |
441 | the repository, index, and working tree), commands that interrogate and |
442 | compare objects, and commands that move objects and references between | |
443 | repositories. | |
444 | ||
89bf2077 | 445 | |
b1f33d62 RR |
446 | Manipulation commands |
447 | ~~~~~~~~~~~~~~~~~~~~~ | |

454 | ||
377e8139 | 455 | include::cmds-plumbinginterrogators.txt[] |
b1f33d62 RR |
456 | |
457 | In general, the interrogate commands do not touch the files in | |
458 | the working tree. | |
459 | ||
460 | ||

467 | typically do not use them directly. |
468 | ||

472 | Internal helper commands | |

476 | users typically do not use them directly. | |

481 | Configuration Mechanism |
482 | ----------------------- | |
483 | ||
2fa090b6 | 484 | Starting from 0.99.9 (actually mid 0.99.8.GIT), `.git/config` file |
5773c9f2 | 485 | is used to hold per-repository configuration options. It is a |
addf88e4 | 486 | simple text file modeled after `.ini` format familiar to some |
5773c9f2 JH |
487 | people. Here is an example: |
488 | ||
489 | ------------ | |
490 | # | |
2fa090b6 | 491 | # A '#' or ';' character indicates a comment. |
5773c9f2 JH |
492 | # |
493 | ||
494 | ; core variables | |
495 | [core] | |
496 | ; Don't trust file modes | |
497 | filemode = false | |
498 | ||
499 | ; user identity | |
500 | [user] | |
501 | name = "Junio C Hamano" | |
502 | email = "junkio@twinsun.com" | |
503 | ||
504 | ------------ | |
505 | ||
506 | Various commands read from the configuration file and adjust | |
06300d97 JN |
507 | their operation accordingly. See linkgit:git-config[1] for a |
508 | list. | |

2cf565c5 DG |
512 | ---------------------- |
513 | <object>:: | |
2fa090b6 | 514 | Indicates the object name for any type of object. |
2cf565c5 DG |
515 | |
516 | <blob>:: | |
2fa090b6 | 517 | Indicates a blob object name. |
2cf565c5 DG |
518 | |
519 | <tree>:: | |
2fa090b6 | 520 | Indicates a tree object name. |
2cf565c5 DG |
521 | |
522 | <commit>:: | |
2fa090b6 | 523 | Indicates a commit object name. |
2cf565c5 DG |
524 | |
525 | <tree-ish>:: | |
2fa090b6 | 526 | Indicates a tree, commit or tag object name. A |
6c84e2e0 DG |
527 | command that takes a <tree-ish> argument ultimately wants to |
528 | operate on a <tree> object but automatically dereferences | |
529 | <commit> and <tag> objects that point at a <tree>. | |
2cf565c5 | 530 | |
043d7605 TT |
531 | <commit-ish>:: |
532 | Indicates a commit or tag object name. A | |
533 | command that takes a <commit-ish> argument ultimately wants to | |
534 | operate on a <commit> object but automatically dereferences | |
535 | <tag> objects that point at a <commit>. | |
536 | ||
2cf565c5 DG |
537 | <type>:: |
538 | Indicates that an object type is required. | |
2fa090b6 | 539 | Currently one of: `blob`, `tree`, `commit`, or `tag`. |
2cf565c5 DG |
540 | |
541 | <file>:: | |
2fa090b6 JH |
542 | Indicates a filename - almost always relative to the |
543 | root of the tree structure `GIT_INDEX_FILE` describes. | |

545 | Symbolic Identifiers |
546 | -------------------- | |
90933efb | 547 | Any git command accepting any <object> can also use the following |
6c84e2e0 | 548 | symbolic notation: |
c1bdacf9 DG |
549 | |
550 | HEAD:: | |
0abcfbff | 551 | indicates the head of the current branch. |
2fa090b6 | 552 | |
c1bdacf9 | 553 | <tag>:: |
2fa090b6 | 554 | a valid tag 'name' |
0abcfbff | 555 | (i.e. a `refs/tags/<tag>` reference). |
2fa090b6 | 556 | |
c1bdacf9 | 557 | <head>:: |
2fa090b6 | 558 | a valid head 'name' |
0abcfbff | 559 | (i.e. a `refs/heads/<head>` reference). |

581 | Environment Variables | |
582 | --------------------- | |
583 | Various git commands use the following environment variables: | |
584 | ||
c1bdacf9 DG |
585 | The git Repository |
586 | ~~~~~~~~~~~~~~~~~~ | |
587 | These environment variables apply to 'all' core git commands. Nb: it | |
588 | is worth noting that they may be used/overridden by SCMS sitting above | |
2fa090b6 | 589 | git so take care if using Cogito etc. |
c1bdacf9 DG |
590 | |
591 | 'GIT_INDEX_FILE':: | |
592 | This environment allows the specification of an alternate | |
5f3aa197 LS |
593 | index file. If not specified, the default of `$GIT_DIR/index` |
594 | is used. | |
c1bdacf9 DG |
595 | |
596 | 'GIT_OBJECT_DIRECTORY':: | |
597 | If the object storage directory is specified via this | |
598 | environment variable then the sha1 directories are created | |
599 | underneath - otherwise the default `$GIT_DIR/objects` | |
600 | directory is used. | |
601 | ||
602 | 'GIT_ALTERNATE_OBJECT_DIRECTORIES':: | |
603 | Due to the immutable nature of git objects, old objects can be | |
604 | archived into shared, read-only directories. This variable | |
80ba074f JS |
605 | specifies a ":" separated (on Windows ";" separated) list |
606 | of git object directories which can be used to search for git | |
607 | objects. New objects will not be written to these directories. | |
c1bdacf9 DG |
608 | |
609 | 'GIT_DIR':: | |
2fa090b6 JH |
610 | If the 'GIT_DIR' environment variable is set then it |
611 | specifies a path to use instead of the default `.git` | |
612 | for the base of the repository. | |
c1bdacf9 | 613 | |
892c41b9 ML |
614 | 'GIT_WORK_TREE':: |
615 | Set the path to the working tree. The value will not be | |
616 | used in combination with repositories found automatically in | |
617 | a .git directory (i.e. $GIT_DIR is not set). | |
618 | This can also be controlled by the '--work-tree' command line | |
619 | option and the core.worktree configuration variable. | |
620 | ||
d49483f0 JT |
621 | 'GIT_NAMESPACE':: |
622 | Set the git namespace; see linkgit:gitnamespaces[7] for details. | |
623 | The '--namespace' command-line option also sets this value. | |
624 | ||
0454dd93 DR |
625 | 'GIT_CEILING_DIRECTORIES':: |
626 | This should be a colon-separated list of absolute paths. | |
627 | If set, it is a list of directories that git should not chdir | |
628 | up into while looking for a repository directory. | |
629 | It will not exclude the current working directory or | |
630 | a GIT_DIR set on the command line or in the environment. | |
631 | (Useful for excluding slow-loading network directories.) | |
632 | ||
cf87463e | 633 | 'GIT_DISCOVERY_ACROSS_FILESYSTEM':: |
e6405517 JH |
634 | When run in a directory that does not have ".git" repository |
635 | directory, git tries to find such a directory in the parent | |
636 | directories to find the top of the working tree, but by default it | |
637 | does not cross filesystem boundaries. This environment variable | |
cf87463e JH |
638 | can be set to true to tell git not to stop at filesystem |
639 | boundaries. Like 'GIT_CEILING_DIRECTORIES', this will not affect | |
640 | an explicit repository directory set via 'GIT_DIR' or on the | |
641 | command line. | |

654 | git Diffs | |
655 | ~~~~~~~~~ | |
d81ed1b5 | 656 | 'GIT_DIFF_OPTS':: |
fde97d8a SE |
657 | Only valid setting is "--unified=??" or "-u??" to set the |
658 | number of context lines shown when a unified diff is created. | |
659 | This takes precedence over any "-U" or "--unified" option | |
660 | value passed on the git diff command line. | |
661 | ||
d81ed1b5 | 662 | 'GIT_EXTERNAL_DIFF':: |
fde97d8a SE |
663 | When the environment variable 'GIT_EXTERNAL_DIFF' is set, the |
664 | program named by it is called, instead of the diff invocation | |
665 | described above. For a path that is added, removed, or modified, | |
666 | 'GIT_EXTERNAL_DIFF' is called with 7 parameters: | |
667 | ||
668 | path old-file old-hex old-mode new-file new-hex new-mode | |
669 | + | |
670 | where: | |
671 | ||
672 | <old|new>-file:: are files GIT_EXTERNAL_DIFF can use to read the | |
673 | contents of <old|new>, | |
674 | <old|new>-hex:: are the 40-hexdigit SHA1 hashes, | |
675 | <old|new>-mode:: are the octal representation of the file modes. | |
fde97d8a SE |
676 | + |
677 | The file parameters can point at the user's working file | |
678 | (e.g. `new-file` in "git-diff-files"), `/dev/null` (e.g. `old-file` | |
679 | when a new file is added), or a temporary file (e.g. `old-file` in the | |
680 | index). 'GIT_EXTERNAL_DIFF' should not worry about unlinking the | |
681 | temporary file --- it is removed when 'GIT_EXTERNAL_DIFF' exits. | |
682 | + | |
683 | For a path that is unmerged, 'GIT_EXTERNAL_DIFF' is called with 1 | |
684 | parameter, <path>. | |

687 | ~~~~~ | |
dbddb714 JN |
688 | 'GIT_MERGE_VERBOSITY':: |
689 | A number controlling the amount of output shown by | |
690 | the recursive merge strategy. Overrides merge.verbosity. | |
5162e697 | 691 | See linkgit:git-merge[1] |
dbddb714 | 692 | |
c27d205a | 693 | 'GIT_PAGER':: |
a7738c77 SG |
694 | This environment variable overrides `$PAGER`. If it is set |
695 | to an empty string or to the value "cat", git will not launch | |
ab54cd6c JN |
696 | a pager. See also the `core.pager` option in |
697 | linkgit:git-config[1]. | |
c27d205a | 698 | |
d5538b41 | 699 | 'GIT_SSH':: |
0b444cdb TR |
700 | If this environment variable is set then 'git fetch' |
701 | and 'git push' will use this command instead | |
2fd02c92 | 702 | of 'ssh' when they need to connect to a remote system. |
483bc4f0 | 703 | The '$GIT_SSH' command will be given exactly two arguments: |
d5538b41 SP |
704 | the 'username@host' (or just 'host') from the URL and the |
705 | shell command to execute on that remote system. | |
706 | + | |
707 | To pass options to the program that you want to list in GIT_SSH | |
708 | you will need to wrap the program and options into a shell script, | |

715 | 'GIT_ASKPASS':: |
716 | If this environment variable is set, then git commands which need to | |
717 | acquire passwords or passphrases (e.g. for HTTP or IMAP authentication) | |
718 | will call this program with a suitable prompt as command line argument | |
719 | and read the password from its STDOUT. See also the 'core.askpass' | |
720 | option in linkgit:git-config[1]. | |

06f59e9f TT |
722 | 'GIT_FLUSH':: |
723 | If this environment variable is set to "1", then commands such | |
0b444cdb TR |
724 | as 'git blame' (in incremental mode), 'git rev-list', 'git log', |
725 | and 'git whatchanged' will force a flush of the output stream | |
06f59e9f TT |
726 | after each commit-oriented record have been flushed. If this |
727 | variable is set to "0", the output of these commands will be done | |
728 | using completely buffered I/O. If this environment variable is | |
729 | not set, git will choose buffered or record-oriented flushing | |
730 | based on whether stdout appears to be redirected to a file or not. | |

575ba9d6 | 732 | 'GIT_TRACE':: |
2886bdb1 CC |
733 | If this variable is set to "1", "2" or "true" (comparison |
734 | is case insensitive), git will print `trace:` messages on | |
575ba9d6 ML |
735 | stderr telling about alias expansion, built-in command |
736 | execution and external command execution. | |
2886bdb1 CC |
737 | If this variable is set to an integer value greater than 1 |
738 | and lower than 10 (strictly) then git will interpret this | |
739 | value as an open file descriptor and will try to write the | |
740 | trace messages into this file descriptor. | |
741 | Alternatively, if this variable is set to an absolute path | |
742 | (starting with a '/' character), git will interpret this | |
743 | as a file path and will try to write the trace messages | |
744 | into it. | |

749 | More detail on the following is available from the | |
750 | link:user-manual.html#git-concepts[git concepts chapter of the | |
6998e4db | 751 | user-manual] and linkgit:gitcore-tutorial[7]. |

752 | |
753 | A git project normally consists of a working directory with a ".git" | |
754 | subdirectory at the top level. The .git directory contains, among other | |
755 | things, a compressed object database representing the complete history | |
756 | of the project, an "index" file which links that history to the current | |
757 | contents of the working tree, and named pointers into that history such | |
758 | as tags and branch heads. | |
759 | ||
760 | The object database contains objects of three main types: blobs, which | |
761 | hold file data; trees, which point to blobs and other trees to build up | |
02ff6250 | 762 | directory hierarchies; and commits, which each reference a single tree |
40dac517 BF |
763 | and some number of parent commits. |
764 | ||
765 | The commit, equivalent to what other systems call a "changeset" or | |
766 | "version", represents a step in the project's history, and each parent | |
767 | represents an immediately preceding step. Commits with more than one | |
768 | parent represent merges of independent lines of development. | |
769 | ||
770 | All objects are named by the SHA1 hash of their contents, normally | |
771 | written as a string of 40 hex digits. Such names are globally unique. | |
772 | The entire history leading up to a commit can be vouched for by signing | |
773 | just that commit. A fourth object type, the tag, is provided for this | |
774 | purpose. | |
775 | ||
776 | When first created, objects are stored in individual files, but for | |
777 | efficiency may later be compressed together into "pack files". | |
778 | ||
779 | Named pointers called refs mark interesting points in history. A ref | |
780 | may contain the SHA1 name of an object or the name of another ref. Refs | |
781 | with names beginning `ref/head/` contain the SHA1 name of the most | |
02ff6250 | 782 | recent commit (or "head") of a branch under development. SHA1 names of |
40dac517 BF |
783 | tags of interest are stored under `ref/tags/`. A special ref named |
784 | `HEAD` contains the name of the currently checked-out branch. | |
785 | ||
786 | The index file is initialized with a list of all paths and, for each | |
787 | path, a blob object and a set of attributes. The blob object represents | |
788 | the contents of the file as of the head of the current branch. The | |
789 | attributes (last modified time, size, etc.) are taken from the | |
790 | corresponding file in the working tree. Subsequent changes to the | |
791 | working tree can be found by comparing these attributes. The index may | |
792 | be updated with new content, and new commits may be created from the | |
793 | content stored in the index. | |
794 | ||
795 | The index is also capable of storing multiple entries (called "stages") | |
796 | for a given pathname. These stages are used to hold the various | |
797 | unmerged version of a file when a merge is in progress. | |
