FYI, have a look at "trap .. EXIT" to defer cleanups like your unlink. It's neat cause it will run even if the script is interrupted / fails before the unlink.

Useful tip, I suppose it will look like:

  temp=$(mktemp)
  trap 'unlink $temp' EXIT
  # Do things

Exactly. And if your cleanup is more involved you can call a cleanup function.
