A custom git "plugin" that allows you to open git repos on Github.com by saying "git open" from inside the repo. This file needs to be chmod +x and needs to be in your path and needs the extension removed.

git-open.rb

#!/usr/bin/env bash
# vim: set ft=ruby:
 
# This file executes as a bash script, which turns around and executes Ruby via
# the line below. The -x argument to Ruby makes it discard everything before
# the second "!ruby" shebang. This allows us to work on Linux, where the
# shebang can only have one argument so we can't directly say
# "#!/usr/bin/env ruby --disable-gems". Thanks for that, Linux.
#
# If this seems confusing, don't worry. You can treat it as a normal Ruby file
# starting with the "!ruby" shebang below.
 
exec /usr/bin/env ruby --disable-gems -x "$0" $*
#!ruby
