.SH "NAME"
git-multi \- execute the same git command in multiple repositories
.SH "VERSION"
.sp
This is \fBv2\&.8\&.0\fR of \fIgit multi\fR \&... hooray!
.SH "SYNOPSIS"
.sp
There are some options for \fBgit multi\fR itself, in which case it is invoked as follows:
.sp
.nf
\fIgit multi\fR \-\-<option> [<option_arguments>]
.fi
.sp
.sp
To execute the same git command in multiple repositories, the invocation is as follows:
.sp
.nf
\fIgit multi\fR <git_command> [<git_command_arguments>]
.fi
.sp
.sp
Both ways of running \fBgit multi\fR take an optional, so\-called "multi repo" argument to limit the operation to the list of repositories in the referenced "multi repo", ie\&. a single GitHub user or a single GitHub organization:
.sp
.nf
\fIgit multi\fR ++<multi_repo> \-\-<option> [<option_arguments>]
.fi
.sp
.sp
and\&...
.sp
.nf
\fIgit multi\fR ++<multi_repo> <git_command> [<git_command_arguments>]
.fi
.sp
.SH "DESCRIPTION"
.sp
Convenient way to execute the same git command in a set of related repositories, which could be all GitHub repos for a given user, or all repos for a given GitHub organization\&.
.sp
Multipe users and organizations can be configured, and by default \fBgit multi\fR operates on all repositories for all users and all orgs; to limit the operation to a single user or a single org, the optional \fB++<multi_repo>\fR argument can be used\&.
.sp
The list of repos for a user or an org is determined via a GitHub API v3 call and cached locally \fI(in binary format)\fR for performance and offline usage\&.
