Hi Ned, About the ls -l | wc -l thing: yeh totally man: I just forgot to mention grep in the first email ... And about the '-' thing: well, that's true; however, don't the '-' and '--' appear on the same line anyways? If they do, then why does it matter? Oh, and to answer your question: The regular expression: '-+' would check for 1 or more occurances of '-' consecutively Take care, Sina -----Original Message----- From: speakup-bounces@xxxxxxxxxxxxxx [mailto:speakup-bounces at braille.uwo.ca] On Behalf Of Ned Sent: Thursday, March 24, 2005 2:03 AM To: Speakup is a screen review system for Linux. Subject: Re: how to chek for the number of options in an app Thanks Sina, In your first post you said: ls --help | wc -l Wouldn't it only count the number of lines within the help file of the ls command? The grep is a much better idea, I tried something like: ls --help | grep -c '-' and it returned 51 because it counted both '-' and '--', but don't know how to ... is there a logical or operator for situations like this? I want to check for '-' or '--' How to do that? Many thanks!
