# Git Push Upstream
# A quick command for people that create a lot of feature branches
#
# Whereas `git push` will return an error if you haven't set the upstream branch
# `gpu` will automatically push to the correct upstream branch
# so you don't have to type `git push --set-upstream origin my_branch` for each new branch

function gpu() {
  local RESPONSE=$( git push 2>&1 )
  local UPSTREAM=$( echo "$RESPONSE" | grep -o "git push --set-upstream origin.*" )
  
  # if we are given an upstream branch, push to that
  if [ -n "$UPSTREAM" ]; then
    echo "$UPSTREAM"
    $UPSTREAM
  else
    # won't show the full "counting objects...delta compression...writing objects" response
    echo "$RESPONSE"
