My first "real" bash script

devtest.sh

#! /bin/bash
clear

case "$2" in
  master) branches=(test develop master);;
  dev) branches=(test develop);;
  *) branches=(test);;
esac

for branch in ${branches[*]}
do
  printf "\n\n\t Synchronizing with %s\n" $branch
  git checkout $branch
  git pull origin $branch
  git merge --no-ff $1
  git push origin $branch
done

printf "\n\n\t All done here, returning to %s\n" $1
git checkout $1

printf "\n\n\t BBye!\n"
exit 0
