Bash script to make a pull request from the current git repository. Tries the upstream remote if possible, otherwise uses origin.

pull_request.sh

# put this in your .bash_profile
pull_request() {
  to_branch=$1
  if [ -z $to_branch ]; then
    to_branch="master"
  fi
  
  # try the upstream branch if possible, otherwise origin will do
  upstream=$(git config --get remote.upstream.url)
  origin=$(git config --get remote.origin.url)
  if [ -z $upstream ]; then
    upstream=$origin
  fi
  
  to_user=$(echo $upstream | sed -e 's/.*[\/:]\([^/]*\)\/[^/]*$/\1/')
  from_user=$(echo $origin | sed -e 's/.*[\/:]\([^/]*\)\/[^/]*$/\1/')
  repo=$(basename `git rev-parse --show-toplevel`)
  from_branch=$(git rev-parse --abbrev-ref HEAD)
  open "https://github.com/$to_user/$repo/pull/new/$to_user:$to_branch...$from_user:$from_branch"
}
 
# usage
pull_request              # PR to master
pull_request other_branch # PR to other_branch

Very nice!

Except that the pull request is edited in your $EDITOR instead of the browser, and it uses the github API.
