The challenge is to identify help|--help|-h anywhere on the command line. Thus, you need to iterate, or do some weird matching against $*. When you iterate in a for loop, it's not easy to get at the next argument, except if you use a state machine. I wanted to avoid that. But you are right, I am wreaking havoc with space-containing arguments. I will have to go back and rework this. I take it you agree with the general principle though? -- .''`. martin f. krafft <madduck@xxxxxxxxxx> : :' : proud Debian developer, author, administrator, and user `. `'` http://people.debian.org/~madduck - http://debiansystem.info `- Debian - when you have better things to do than fixing systems "it is easier to be a lover than a husband for the simple reason that it is more difficult to be witty every day than to say pretty things from time to time." -- honoré de balzac
