1git-send-pack(1) 2================ 3 4NAME 5---- 6git-send-pack - Push objects over Git protocol to another repository 7 8 9SYNOPSIS 10-------- 11[verse] 12'git send-pack' [--all] [--dry-run] [--force] [--receive-pack=<git-receive-pack>] 13 [--verbose] [--thin] [--atomic] 14 [--[no-]signed|--signed=(true|false|if-asked)] 15 [<host>:]<directory> [<ref>...] 16 17DESCRIPTION 18----------- 19Usually you would want to use 'git push', which is a 20higher-level wrapper of this command, instead. See linkgit:git-push[1]. 21 22Invokes 'git-receive-pack' on a possibly remote repository, and 23updates it from the current repository, sending named refs. 24 25 26OPTIONS 27------- 28--receive-pack=<git-receive-pack>:: 29 Path to the 'git-receive-pack' program on the remote 30 end. Sometimes useful when pushing to a remote 31 repository over ssh, and you do not have the program in 32 a directory on the default $PATH. 33 34--exec=<git-receive-pack>:: 35 Same as --receive-pack=<git-receive-pack>. 36 37--all:: 38 Instead of explicitly specifying which refs to update, 39 update all heads that locally exist. 40 41--stdin:: 42 Take the list of refs from stdin, one per line. If there 43 are refs specified on the command line in addition to this 44 option, then the refs from stdin are processed after those 45 on the command line. 46+ 47If `--stateless-rpc` is specified together with this option then 48the list of refs must be in packet format (pkt-line). Each ref must 49be in a separate packet, and the list must end with a flush packet. 50 51--dry-run:: 52 Do everything except actually send the updates. 53 54--force:: 55 Usually, the command refuses to update a remote ref that 56 is not an ancestor of the local ref used to overwrite it. 57 This flag disables the check. What this means is that 58 the remote repository can lose commits; use it with 59 care. 60 61--verbose:: 62 Run verbosely. 63 64--thin:: 65 Send a "thin" pack, which records objects in deltified form based 66 on objects not included in the pack to reduce network traffic. 67 68--atomic:: 69 Use an atomic transaction for updating the refs. If any of the refs 70 fails to update then the entire push will fail without changing any 71 refs. 72 73--[no-]signed:: 74--signed=(true|false|if-asked):: 75 GPG-sign the push request to update refs on the receiving 76 side, to allow it to be checked by the hooks and/or be 77 logged. If `false` or `--no-signed`, no signing will be 78 attempted. If `true` or `--signed`, the push will fail if the 79 server does not support signed pushes. If set to `if-asked`, 80 sign if and only if the server supports signed pushes. The push 81 will also fail if the actual call to `gpg --sign` fails. See 82 linkgit:git-receive-pack[1] for the details on the receiving end. 83 84--push-option=<string>:: 85 Pass the specified string as a push option for consumption by 86 hooks on the server side. If the server doesn't support push 87 options, error out. See linkgit:git-push[1] and 88 linkgit:githooks[5] for details. 89 90<host>:: 91 A remote host to house the repository. When this 92 part is specified, 'git-receive-pack' is invoked via 93 ssh. 94 95<directory>:: 96 The repository to update. 97 98<ref>...:: 99 The remote refs to update. 100 101 102Specifying the Refs 103------------------- 104 105There are three ways to specify which refs to update on the 106remote end. 107 108With `--all` flag, all refs that exist locally are transferred to 109the remote side. You cannot specify any '<ref>' if you use 110this flag. 111 112Without `--all` and without any '<ref>', the heads that exist 113both on the local side and on the remote side are updated. 114 115When one or more '<ref>' are specified explicitly (whether on the 116command line or via `--stdin`), it can be either a 117single pattern, or a pair of such pattern separated by a colon 118":" (this means that a ref name cannot have a colon in it). A 119single pattern '<name>' is just a shorthand for '<name>:<name>'. 120 121Each pattern pair consists of the source side (before the colon) 122and the destination side (after the colon). The ref to be 123pushed is determined by finding a match that matches the source 124side, and where it is pushed is determined by using the 125destination side. The rules used to match a ref are the same 126rules used by 'git rev-parse' to resolve a symbolic ref 127name. See linkgit:git-rev-parse[1]. 128 129 - It is an error if <src> does not match exactly one of the 130 local refs. 131 132 - It is an error if <dst> matches more than one remote refs. 133 134 - If <dst> does not match any remote ref, either 135 136 * it has to start with "refs/"; <dst> is used as the 137 destination literally in this case. 138 139 * <src> == <dst> and the ref that matched the <src> must not 140 exist in the set of remote refs; the ref matched <src> 141 locally is used as the name of the destination. 142 143Without `--force`, the <src> ref is stored at the remote only if 144<dst> does not exist, or <dst> is a proper subset (i.e. an 145ancestor) of <src>. This check, known as "fast-forward check", 146is performed in order to avoid accidentally overwriting the 147remote ref and lose other peoples' commits from there. 148 149With `--force`, the fast-forward check is disabled for all refs. 150 151Optionally, a <ref> parameter can be prefixed with a plus '+' sign 152to disable the fast-forward check only on that ref. 153 154GIT 155--- 156Part of the linkgit:git[1] suite
