I just wanted to make it run under zsh and clean up bashisms. Cleaning up bashsms and leaving bash in shebang doesn't look very logical to me. If it's clean it should work in any shell. If it can work only in bash then what's the point of cleaning it from bashisms? Anyway, I made it to work in dash too.
