If you only want to access the first parameter, use $1, and for good form, check it before further processing. Your use of quotes to include the parameter is already good form. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

To make a shell script as portable as possible, use /bin/sh. Bash is a third party shell, that isn't included in a base installation (you're not using bash as root's shell, are you?).

(sheepishly, and hanging my head) yes. does anybody have a
csh/cshrc-alias to a bash/bashrc-alias script? i've got
hundreds of aliases to be just deleted, i suppose, by dozens
more.

I already have things like setenv aliased to ksh/zsh/borne-again/ and probably even /bin/sh || /bin/ash. I thought that especially bash was still persnikity. It used to be centuries ago, so I just stuck with zsh. Another deal was that I rarely use root, so it didn't worth it. But now, sweating the End of Days, yup.
