Maybe you want set -e   www davidpashley com articles writing-robust-shell-scripts html id2382181      This tells bash that it should exit the script if any statement returns a non-true return value  The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier  Again  for readability you may want to use set -o errexit
