Antonio, grep uses regex (regular expressions), not globbing (which is what the shell uses). In regex, '*' means "0 or more of the previous character", so 'agr*' matches 'ag', 'agr', 'agrr', 'agrrrrrrrrr', etc. Thus Robin's output contained every line with 'ag' in it. The globbing you're attempting here is actually the way regex works by default. "grep 'agr'" finds any line containing the sequence 'agr' no matter what else is on that line. If you need a wildcard, you have to use '.', which matches any character once, followed by '*'. E.g., "grep agr.*driver" would find the line "agrserial: Loading module Agere Modem Interface driver version 2.1.60.0.Linspire (2005-11-16)" HTH, -- Joshua Crawford ... http://geocities.com/mortarn http://www.rewardscentral.com.au/Join/Default.aspx?refer=mortarn Be rewarded!
