4 | NAME | |
5 | ---- | |
6 | git - the stupid content tracker | |
7 | ||
8 | ||
9 | SYNOPSIS | |
10 | -------- | |
cb22bc44 | 11 | 'git' [--version] [--exec-path[=GIT_EXEC_PATH]] [--help] COMMAND [ARGS] |
2cf565c5 DG |
12 | |
13 | DESCRIPTION | |
14 | ----------- | |
cb22bc44 AE |
15 | 'git' is both a program and a directory content tracker system. |
16 | The program 'git' is just a wrapper to reach the core git programs | |
17 | (or a potty if you like, as it's not exactly porcelain but still | |
18 | brings your stuff to the plumbing). | |
19 | ||
20 | OPTIONS | |
21 | ------- | |
22 | --version:: | |
23 | prints the git suite version that the 'git' program came from. | |
24 | ||
25 | --help:: | |
26 | prints the synopsis and a list of available commands. | |
97fc6c5f AE |
27 | If a git command is named this option will bring up the |
28 | man-page for that command. | |
cb22bc44 AE |
29 | |
30 | --exec-path:: | |
31 | path to wherever your core git programs are installed. | |
32 | This can also be controlled by setting the GIT_EXEC_PATH | |
33 | environment variable. If no path is given 'git' will print | |
34 | the current setting and then exit. | |

8b15e2fb JH |
39 | at the link:tutorial.html[tutorial] document. If you are |
40 | migrating from CVS, link:cvs-migration.html[cvs migration] | |
41 | document may be helpful after you finish the tutorial. | |

43 | The <<Discussion>> section below contains much useful definition |
44 | and clarification info - read that first. After that, if you | |
45 | are interested in using git to manage (version control) | |
8b15e2fb JH |
46 | projects, use link:everyday.html[Everyday GIT] as a guide to the |
47 | minimum set of commands you need to know for day-to-day work. | |

49 | After you get the general feel from the tutorial and this |
50 | overview page, you may want to take a look at the | |
51 | link:howto-index.html[howto] documents. | |
52 | ||
8b15e2fb JH |
53 | If you are writing your own Porcelain, you need to be familiar |
54 | with most of the low level commands --- I suggest starting from | |
55 | gitlink:git-update-index[1] and gitlink:git-read-tree[1]. | |

64 | Commands Overview | |
65 | ----------------- | |
66 | The git commands can helpfully be split into those that manipulate | |
2fa090b6 | 67 | the repository, the index and the files in the working tree, those that |
2f2de9b4 JH |
68 | interrogate and compare them, and those that moves objects and |
69 | references between repositories. | |
2cf565c5 | 70 | |
62033318 JH |
71 | In addition, git itself comes with a spartan set of porcelain |
72 | commands. They are usable but are not meant to compete with real | |
73 | Porcelains. | |
74 | ||
90933efb | 75 | There are also some ancillary programs that can be viewed as useful |
204ee6a9 DG |
76 | aids for using the core commands but which are unlikely to be used by |
77 | SCMs layered over git. | |

426 | Configuration Mechanism |
427 | ----------------------- | |
428 | ||
2fa090b6 | 429 | Starting from 0.99.9 (actually mid 0.99.8.GIT), `.git/config` file |
5773c9f2 JH |
430 | is used to hold per-repository configuration options. It is a |
431 | simple text file modelled after `.ini` format familiar to some | |
432 | people. Here is an example: | |
433 | ||
434 | ------------ | |
435 | # | |
2fa090b6 | 436 | # A '#' or ';' character indicates a comment. |
5773c9f2 JH |
437 | # |
438 | ||
439 | ; core variables | |
440 | [core] | |
441 | ; Don't trust file modes | |
442 | filemode = false | |
443 | ||
444 | ; user identity | |
445 | [user] | |
446 | name = "Junio C Hamano" | |
447 | email = "junkio@twinsun.com" | |
448 | ||
449 | ------------ | |
450 | ||
451 | Various commands read from the configuration file and adjust | |
452 | their operation accordingly. | |

6c84e2e0 | 455 | Identifier Terminology |
2cf565c5 DG |
456 | ---------------------- |
457 | <object>:: | |
2fa090b6 | 458 | Indicates the object name for any type of object. |
2cf565c5 DG |
459 | |
460 | <blob>:: | |
2fa090b6 | 461 | Indicates a blob object name. |
2cf565c5 DG |
462 | |
463 | <tree>:: | |
2fa090b6 | 464 | Indicates a tree object name. |
2cf565c5 DG |
465 | |
466 | <commit>:: | |
2fa090b6 | 467 | Indicates a commit object name. |
2cf565c5 DG |
468 | |
469 | <tree-ish>:: | |
2fa090b6 | 470 | Indicates a tree, commit or tag object name. A |
6c84e2e0 DG |
471 | command that takes a <tree-ish> argument ultimately wants to |
472 | operate on a <tree> object but automatically dereferences | |
473 | <commit> and <tag> objects that point at a <tree>. | |
2cf565c5 DG |
474 | |
475 | <type>:: | |
476 | Indicates that an object type is required. | |
2fa090b6 | 477 | Currently one of: `blob`, `tree`, `commit`, or `tag`. |
2cf565c5 DG |
478 | |
479 | <file>:: | |
2fa090b6 JH |
480 | Indicates a filename - almost always relative to the |
481 | root of the tree structure `GIT_INDEX_FILE` describes. | |

483 | Symbolic Identifiers |
484 | -------------------- | |
90933efb | 485 | Any git command accepting any <object> can also use the following |
6c84e2e0 | 486 | symbolic notation: |
c1bdacf9 DG |
487 | |
488 | HEAD:: | |
2fa090b6 JH |
489 | indicates the head of the current branch (i.e. the |
490 | contents of `$GIT_DIR/HEAD`). | |
491 | ||
c1bdacf9 | 492 | <tag>:: |
2fa090b6 JH |
493 | a valid tag 'name' |
494 | (i.e. the contents of `$GIT_DIR/refs/tags/<tag>`). | |
495 | ||
c1bdacf9 | 496 | <head>:: |
2fa090b6 JH |
497 | a valid head 'name' |
498 | (i.e. the contents of `$GIT_DIR/refs/heads/<head>`). | |
499 | ||
c1bdacf9 | 500 | <snap>:: |
2fa090b6 JH |
501 | a valid snapshot 'name' |
502 | (i.e. the contents of `$GIT_DIR/refs/snap/<snap>`). | |

519 | Environment Variables | |
520 | --------------------- | |
521 | Various git commands use the following environment variables: | |
522 | ||
c1bdacf9 DG |
523 | The git Repository |
524 | ~~~~~~~~~~~~~~~~~~ | |
525 | These environment variables apply to 'all' core git commands. Nb: it | |
526 | is worth noting that they may be used/overridden by SCMS sitting above | |
2fa090b6 | 527 | git so take care if using Cogito etc. |
c1bdacf9 DG |
528 | |
529 | 'GIT_INDEX_FILE':: | |
530 | This environment allows the specification of an alternate | |
5f3aa197 LS |
531 | index file. If not specified, the default of `$GIT_DIR/index` |
532 | is used. | |
c1bdacf9 DG |
533 | |
534 | 'GIT_OBJECT_DIRECTORY':: | |
535 | If the object storage directory is specified via this | |
536 | environment variable then the sha1 directories are created | |
537 | underneath - otherwise the default `$GIT_DIR/objects` | |
538 | directory is used. | |
539 | ||
540 | 'GIT_ALTERNATE_OBJECT_DIRECTORIES':: | |
541 | Due to the immutable nature of git objects, old objects can be | |
542 | archived into shared, read-only directories. This variable | |
90933efb | 543 | specifies a ":" separated list of git object directories which |
c1bdacf9 DG |
544 | can be used to search for git objects. New objects will not be |
545 | written to these directories. | |
546 | ||
547 | 'GIT_DIR':: | |
2fa090b6 JH |
548 | If the 'GIT_DIR' environment variable is set then it |
549 | specifies a path to use instead of the default `.git` | |
550 | for the base of the repository. | |
