1git-send-pack(1) 2================ 3 4NAME 5---- 6git-send-pack - Push objects over git protocol to another repository 7 8 9SYNOPSIS 10-------- 11'git send-pack' [--all] [--dry-run] [--force] [--receive-pack=<git-receive-pack>] [--verbose] [--thin] [<host>:]<directory> [<ref>...] 12 13DESCRIPTION 14----------- 15Usually you would want to use 'git push', which is a 16higher-level wrapper of this command, instead. See linkgit:git-push[1]. 17 18Invokes 'git-receive-pack' on a possibly remote repository, and 19updates it from the current repository, sending named refs. 20 21 22OPTIONS 23------- 24--receive-pack=<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 30--exec=<git-receive-pack>:: 31 Same as \--receive-pack=<git-receive-pack>. 32 33--all:: 34 Instead of explicitly specifying which refs to update, 35 update all heads that locally exist. 36 37--dry-run:: 38 Do everything except actually send the updates. 39 40--force:: 41 Usually, the command refuses to update a remote ref that 42 is not an ancestor of the local ref used to overwrite it. 43 This flag disables the check. What this means is that 44 the remote repository can lose commits; use it with 45 care. 46 47--verbose:: 48 Run verbosely. 49 50--thin:: 51 Send a "thin" pack, which records objects in deltified form based 52 on objects not included in the pack to reduce network traffic. 53 54<host>:: 55 A remote host to house the repository. When this 56 part is specified, 'git-receive-pack' is invoked via 57 ssh. 58 59<directory>:: 60 The repository to update. 61 62<ref>...:: 63 The remote refs to update. 64 65 66Specifying the Refs 67------------------- 68 69There are three ways to specify which refs to update on the 70remote end. 71 72With '--all' flag, all refs that exist locally are transferred to 73the remote side. You cannot specify any '<ref>' if you use 74this flag. 75 76Without '--all' and without any '<ref>', the heads that exist 77both on the local side and on the remote side are updated. 78 79When one or more '<ref>' are specified explicitly, it can be either a 80single pattern, or a pair of such pattern separated by a colon 81":" (this means that a ref name cannot have a colon in it). A 82single pattern '<name>' is just a shorthand for '<name>:<name>'. 83 84Each pattern pair consists of the source side (before the colon) 85and the destination side (after the colon). The ref to be 86pushed is determined by finding a match that matches the source 87side, and where it is pushed is determined by using the 88destination side. The rules used to match a ref are the same 89rules used by 'git rev-parse' to resolve a symbolic ref 90name. See linkgit:git-rev-parse[1]. 91 92 - It is an error if <src> does not match exactly one of the 93 local refs. 94 95 - It is an error if <dst> matches more than one remote refs. 96 97 - If <dst> does not match any remote ref, either 98 99 * it has to start with "refs/"; <dst> is used as the 100 destination literally in this case. 101 102 * <src> == <dst> and the ref that matched the <src> must not 103 exist in the set of remote refs; the ref matched <src> 104 locally is used as the name of the destination. 105 106Without '--force', the <src> ref is stored at the remote only if 107<dst> does not exist, or <dst> is a proper subset (i.e. an 108ancestor) of <src>. This check, known as "fast-forward check", 109is performed in order to avoid accidentally overwriting the 110remote ref and lose other peoples' commits from there. 111 112With '--force', the fast-forward check is disabled for all refs. 113 114Optionally, a <ref> parameter can be prefixed with a plus '+' sign 115to disable the fast-forward check only on that ref. 116 117 118Author 119------ 120Written by Linus Torvalds <torvalds@osdl.org> 121 122Documentation 123-------------- 124Documentation by Junio C Hamano. 125 126GIT 127--- 128Part of the linkgit:git[1] suite
