Just as an aside to this particular thread. I am sure I read somewhere that it is usually best to write scripts for sh , ie /bin/sh as many of the others are located in /usr/something which when the file system is not stable may or may not be accessible. man sh would be your friend here and quite often shell scripts that are run from cron are written with this shell in mind. good luck LukeK ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

a good way to save a keystroke?
I wanted to look at a file and figured why not pipe the output of which to more, which of course didn't work so I figured if I backticked the which output with more in front that would work, and apparently it does (though I'm not sure that the cmd itself wasn't executed?). e.g. more `which apachectl` Is this a reasonable way to get what I'm after, or a bad thing?

That's fine. The command that gets executed is which, not apachectl, so there's no need to worry on that account. Ceri -- pgp0.pgp Description: PGP signature

It's fine, although anything inside the ticks does in fact get executed, eg which apachectl expands to /usr/local/bin/apachectl (not running apache, don't remember the freebsd location offhand but you get the point) so then the literal text '/usr/local/bin/apachectl' replaces the command inside the ticks to become: more /usr/local/bin/apachectl So yep, it's doing what you want, the way you wanted to...use something similar fairly often myself, although note that the 'current' standard for executing commands is now $(cmd), eg more $(which apachectl) Scott ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
