That was my first thought, but then grep returns the lines which that appears, and what if it is in another field besides the first field? (Like name or something) - (ok i answered my own question, use a regexp, but im trying to make this really simple! and I kinda forget how to do regexps anyway...) I was thinking of just using the command id, but for either grep or id, how do I make a variable equal to true or false depending on what grep or another command returns?
