.SH "DESCRIPTION"
hub enhances various git commands to ease most common workflows with GitHub\.
.
.TP
\fBhub \-\-noop\fR \fICOMMAND\fR
Shows which command(s) would be run as a result of the current command\. Doesn\'t perform anything\.
.
.TP
\fBhub alias\fR [\fB\-s\fR] \fISHELL\fR
Writes shell aliasing code for \fISHELL\fR (\fBbash\fR, \fBsh\fR, \fBzsh\fR, \fBcsh\fR) to standard output\. With the \fB\-s\fR option, the output of this command can be evaluated directly within the shell:
.
.br
\fBeval $(hub alias \-s bash)\fR
.
.TP
\fBgit init\fR \fB\-g\fR \fIOPTIONS\fR
Create a git repository as with git\-init(1) and add remote \fBorigin\fR at "git@github\.com:\fIUSER\fR/\fIREPOSITORY\fR\.git"; \fIUSER\fR is your GitHub username and \fIREPOSITORY\fR is the current working directory\'s basename\.
.
.TP
\fBgit clone\fR [\fB\-p\fR] \fIOPTIONS\fR [\fIUSER\fR\fB/\fR]\fIREPOSITORY\fR \fIDIRECTORY\fR
Clone repository "git://github\.com/\fIUSER\fR/\fIREPOSITORY\fR\.git" into \fIDIRECTORY\fR as with git\-clone(1)\. When \fIUSER\fR/ is omitted, assumes your GitHub login\. With \fB\-p\fR, clone private repositories over SSH\. For repositories under your GitHub login, \fB\-p\fR is implicit\.
.
.TP
\fBgit remote add\fR [\fB\-p\fR] \fIOPTIONS\fR \fIUSER\fR[\fB/\fR\fIREPOSITORY\fR]
Add remote "git://github\.com/\fIUSER\fR/\fIREPOSITORY\fR\.git" as with git\-remote(1)\. When /\fIREPOSITORY\fR is omitted, the basename of the current working directory is used\. With \fB\-p\fR, use private remote "git@github\.com:\fIUSER\fR/\fIREPOSITORY\fR\.git"\. If \fIUSER\fR is "origin" then uses your GitHub login\.
.
.TP
\fBgit remote set\-url\fR [\fB\-p\fR] \fIOPTIONS\fR \fIREMOTE\-NAME\fR \fIUSER\fR[/\fIREPOSITORY\fR]
Sets the url of remote \fIREMOTE\-NAME\fR using the same rules as \fBgit remote add\fR\.
.
.TP
\fBgit fetch\fR \fIUSER\-1\fR,[\fIUSER\-2\fR,\.\.\.]
Adds missing remote(s) with \fBgit remote add\fR prior to fetching\. New remotes are only added if they correspond to valid forks on GitHub\.
.
.TP
\fBgit checkout\fR \fIPULLREQ\-URL\fR [\fIBRANCH\fR]
Checks out the head of the pull request as a local branch, to allow for reviewing, rebasing and otherwise cleaning up the commits in the pull request before merging\. The name of the local branch can explicitly be set with \fIBRANCH\fR\.
.
.TP
\fBgit cherry\-pick\fR \fIGITHUB\-REF\fR
Cherry\-pick a commit from a fork using either full URL to the commit or GitHub\-flavored Markdown notation, which is \fBuser@sha\fR\. If the remote doesn\'t yet exist, it will be added\. A \fBgit fetch <user>\fR is issued prior to the cherry\-pick attempt\.
.
.TP
\fBgit [am|apply]\fR \fIGITHUB\-URL\fR
Downloads the patch file for the pull request or commit at the URL and applies that patch from disk with \fBgit am\fR or \fBgit apply\fR\. Similar to \fBcherry\-pick\fR, but doesn\'t add new remotes\. \fBgit am\fR creates commits while preserving authorship info while \fBapply\fR only applies the patch to the working copy\.
.
.TP
\fBgit push\fR \fIREMOTE\-1\fR,\fIREMOTE\-2\fR,\.\.\.,\fIREMOTE\-N\fR [\fIREF\fR]
Push \fIREF\fR to each of \fIREMOTE\-1\fR through \fIREMOTE\-N\fR by executing multiple \fBgit push\fR commands\.
.
.TP
\fBgit submodule add\fR [\fB\-p\fR] \fIOPTIONS\fR [\fIUSER\fR/]\fIREPOSITORY\fR \fIDIRECTORY\fR
Submodule repository "git://github\.com/\fIUSER\fR/\fIREPOSITORY\fR\.git" into \fIDIRECTORY\fR as with git\-submodule(1)\. When \fIUSER\fR/ is omitted, assumes your GitHub login\. With \fB\-p\fR, use private remote "git@github\.com:\fIUSER\fR/\fIREPOSITORY\fR\.git"\.
.
.TP
\fBgit help\fR
Display enhanced git\-help(1)\.
.
.P
hub also adds some custom commands that are otherwise not present in git:
.
.TP
\fBgit create\fR [\fINAME\fR] [\fB\-p\fR] [\fB\-d\fR \fIDESCRIPTION\fR] [\fB\-h\fR \fIHOMEPAGE\fR]
Create a new public GitHub repository from the current git repository and add remote \fBorigin\fR at "git@github\.com:\fIUSER\fR/\fIREPOSITORY\fR\.git"; \fIUSER\fR is your GitHub username and \fIREPOSITORY\fR is the current working directory name\. To explicitly name the new repository, pass in \fINAME\fR, optionally in \fIORGANIZATION\fR/\fINAME\fR form to create under an organization you\'re a member of\. With \fB\-p\fR, create a private repository, and with \fB\-d\fR and \fB\-h\fR set the repository\'s description and homepage URL, respectively\.
.
.TP
\fBgit browse\fR [\fB\-u\fR] [[\fIUSER\fR\fB/\fR]\fIREPOSITORY\fR] [SUBPAGE]
Open repository\'s GitHub page in the system\'s default web browser using \fBopen(1)\fR or the \fBBROWSER\fR env variable\. If the repository isn\'t specified, \fBbrowse\fR opens the page of the repository found in the current directory\. If SUBPAGE is specified, the browser will open on the specified subpage: one of "wiki", "commits", "issues" or other (the default is "tree")\.
.
.TP
\fBgit compare\fR [\fB\-u\fR] [\fIUSER\fR] [\fISTART\fR\.\.\.]\fIEND\fR
Open a GitHub compare view page in the system\'s default web browser\. \fISTART\fR to \fIEND\fR are branch names, tag names, or commit SHA1s specifying the range of history to compare\. If a range with two dots (\fBa\.\.b\fR) is given, it will be transformed into one with three dots\. If \fISTART\fR is omitted, GitHub will compare against the base branch (the default is "master")\.
.
.TP
\fBgit fork\fR [\fB\-\-no\-remote\fR]
Forks the original project (referenced by "origin" remote) on GitHub and adds a new remote for it under your username\. Requires \fBgithub\.token\fR to be set (see CONFIGURATION)\.
.
.TP
\fBgit pull\-request\fR [\fB\-f\fR] [\fITITLE\fR|\fB\-i\fR \fIISSUE\fR] [\fB\-b\fR \fIBASE\fR] [\fB\-h\fR \fIHEAD\fR]
\fBgit pull\-request\fR [\fB\-f\fR] \fIISSUE\-URL\fR [\fB\-h\fR \fIHEAD\fR] Opens a pull request on GitHub for the project that the "origin" remote points to\. The default head of the pull request is the current branch\. Both base and head of the pull request can be explicitly given in one of the following formats: "branch", "owner:branch", "owner/repo:branch"\. This command will abort operation if it detects that the current topic branch has local commits that are not yet pushed to its upstream branch on the remote\. To skip this check, use \fB\-f\fR\.
.
.IP
If \fITITLE\fR is omitted, a text editor will open in which title and body of the pull request can be entered in the same manner as git commit message\.
.
.IP
If instead of normal \fITITLE\fR an issue number is given with \fB\-i\fR, the pull request will be attached to an existing GitHub issue\. Alternatively, instead of title you can paste a full URL to an issue on GitHub\.
.
.SH "CONFIGURATION"
Use git\-config(1) to display the currently configured GitHub username:
.
.IP "" 4
.
.nf

$ git config \-\-global github\.user
.
.fi
.
.IP "" 0
.
.P
Or, set the GitHub username and token with:
.
.IP "" 4
.
.nf

$ git config \-\-global github\.user <username>
$ git config \-\-global github\.token <token>
.
.fi
.
.IP "" 0
.
.P
You can override these values with \fIGITHUB_USER\fR and \fIGITHUB_TOKEN\fR environment variables\.
.
.P
See \fIhttp://help\.github\.com/set\-your\-user\-name\-email\-and\-github\-token/\fR for more information\.
.
.P
If you prefer the HTTPS protocol for GitHub repositories, you can set "hub\.protocol" to "https"\. This will affect \fBclone\fR, \fBfork\fR, \fBremote add\fR and other operations that expand references to GitHub repositories as full URLs that otherwise use git and ssh protocols\.
