This Ruby gem installs the git-update command, which scans git directory trees and updates them. Directories containing a file called .ignore are ignored.

The git-update command requires at least one parameter: the names of the top-level directories to update.

The following updates the directory tree of git repos under the /data/work directory:

$ git update /data/work

The following accomplishes the same thing:

$ export work=/data/work

$ git update $work

The following accomplishes the same thing:

$ git-update $work

The following updates the directory trees of git repos pointed to by $work and $sites:

$ export work=/data/work

$ export sites=/var/www

$ git update $work $sites

Type the following at a shell prompt:

$ gem install git_tree
