RE: Specifying sort fields
Thank you that worked. You know that nowhere in the 'man sort' info does it say that to use sort command you have to use pipe commands to feed it data. How is somebody without UNIX programming background going to read that and know how to feed sort it's data to sort? Don't you think the man sort info needs updating to explain this fact? Even some examples at end of technical info would go long way to making the 'man sort' info user friendly and meaningfully. -Original Message- From: Dan Nelson [mailto:[EMAIL PROTECTED] Sent: Thursday, April 22, 2004 5:35 PM To: JJB Cc: [EMAIL PROTECTED] ORG Subject: Re: Specifying sort fields In the last episode (Apr 22), JJB said: How to specify the fields the sort program is to sort on?

DESCRIPTION Write sorted concatenation of all FILE(s) to standard output. and a bit farther down: With no FILE, or when FILE is -, read standard input. I agree that examples would be nice. -- Dan Nelson [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You know that nowhere in the 'man sort' info does it say that to use sort command you have to use pipe commands to feed it data. It doesn't because you don't. The syntax is: sort [OPTION]... [FILE]... which means that you may optionally specify the name of the file to process. For what it's worth, the wide majority of Unix commands accept input from pipes and can write output to pipes. -- Kirk Strauser 94 outdated ports on the box, 94 outdated ports.
