Yes, you wrote the admonition without the encouragement. To elaborate on Santiago's addition: Restrict your script to POSIX features when possible so that it may use /bin/sh as its interpreter. If your script works with ash, it's probably POSIX compliant, but if you are in doubt, use /bin/bash. Guy
