10 | -------- | |
ab9b3138 | 11 | 'git-send-pack' [--all] [--force] [--exec=<git-receive-pack>] [<host>:]<directory> [<ref>...] |

13 | DESCRIPTION | |
14 | ----------- | |
5cb545fa JH |
15 | Usually you would want to use gitlink:git-push[1] which is a |
16 | higher level wrapper of this command instead. | |
17 | ||
2a245013 | 18 | Invokes 'git-receive-pack' on a possibly remote repository, and |
ab9b3138 | 19 | updates it from the current repository, sending named refs. |
2a245013 JH |
20 | |
21 | ||
22 | OPTIONS | |
23 | ------- | |
24 | --exec=<git-receive-pack>:: | |
25 | Path to the 'git-receive-pack' program on the remote | |
26 | end. Sometimes useful when pushing to a remote | |
27 | repository over ssh, and you do not have the program in | |
28 | a directory on the default $PATH. | |
29 | ||
9553d20b JH |
30 | --all:: |
31 | Instead of explicitly specifying which refs to update, | |
32 | update all refs that locally exist. | |
33 | ||
ab9b3138 JH |
34 | --force:: |
35 | Usually, the command refuses to update a remote ref that | |
36 | is not an ancestor of the local ref used to overwrite it. | |
37 | This flag disables the check. What this means is that | |
38 | the remote repository can lose commits; use it with | |
39 | care. | |
40 | ||
2a245013 JH |
41 | <host>:: |
42 | A remote host to house the repository. When this | |
43 | part is specified, 'git-receive-pack' is invoked via | |
44 | ssh. | |
45 | ||
46 | <directory>:: | |
47 | The repository to update. | |
48 | ||
23bed43d | 49 | <ref>...:: |
9553d20b JH |
50 | The remote refs to update. |
51 | ||
52 | ||
53 | Specifying the Refs | |
54 | ------------------- | |
55 | ||
56 | There are three ways to specify which refs to update on the | |
57 | remote end. | |
58 | ||
abda1ef5 | 59 | With '--all' flag, all refs that exist locally are transferred to |
ab9b3138 | 60 | the remote side. You cannot specify any '<ref>' if you use |
9553d20b JH |
61 | this flag. |
62 | ||
ab9b3138 | 63 | Without '--all' and without any '<ref>', the refs that exist |
9553d20b JH |
64 | both on the local side and on the remote side are updated. |
65 | ||
df8baa42 | 66 | When one or more '<ref>' are specified explicitly, it can be either a |
9553d20b | 67 | single pattern, or a pair of such pattern separated by a colon |
df8baa42 | 68 | ":" (this means that a ref name cannot have a colon in it). A |
9553d20b | 69 | single pattern '<name>' is just a shorthand for '<name>:<name>'. |
ab9b3138 | 70 | |
9553d20b | 71 | Each pattern pair consists of the source side (before the colon) |
ab9b3138 | 72 | and the destination side (after the colon). The ref to be |
9553d20b JH |
73 | pushed is determined by finding a match that matches the source |
74 | side, and where it is pushed is determined by using the | |
75 | destination side. | |
76 | ||
ab9b3138 JH |
77 | - It is an error if <src> does not match exactly one of the |
78 | local refs. | |
9553d20b JH |
79 | |
80 | - It is an error if <dst> matches more than one remote refs. | |
81 | ||
82 | - If <dst> does not match any remote ref, either | |
83 | ||
df8baa42 | 84 | * it has to start with "refs/"; <dst> is used as the |
9553d20b JH |
85 | destination literally in this case. |
86 | ||
df8baa42 | 87 | * <src> == <dst> and the ref that matched the <src> must not |
9553d20b JH |
88 | exist in the set of remote refs; the ref matched <src> |
89 | locally is used as the name of the destination. | |
90 | ||
ab9b3138 JH |
91 | Without '--force', the <src> ref is stored at the remote only if |
92 | <dst> does not exist, or <dst> is a proper subset (i.e. an | |
93 | ancestor) of <src>. This check, known as "fast forward check", | |
94 | is performed in order to avoid accidentally overwriting the | |
95 | remote ref and lose other peoples' commits from there. | |
96 | ||
97 | With '--force', the fast forward check is disabled for all refs. | |
98 | ||
99 | Optionally, a <ref> parameter can be prefixed with a plus '+' sign | |
100 | to disable the fast-forward check only on that ref. | |
