I found GetOpt to be convenient when used properly. I would be interested to hear your comment on my article: http://tinyurl.com/23ya4 > Error Handling > Error handling is one thing which is done much more thoroughly in > HsUnix than in shells.

Most sh derivaties have -e set option, which causes the shell to (taken from FreeBSD sh man page): -e errexit Exit immediately if any untested command fails in non-interactive mode. The exit status of a command is considered to be explic- itly tested if the command is used to control an if, elif, while, or until; or if the command is the left hand operand of an ``&&'' or ``||'' operator. I use it almost always in my shell scripts.
