[linux-help] Re: Regexp question

[John <jmresler@xxxxxxxxxxx>]

Are you using grep, egrep, sed, awk, find? They all use slightly different sets
of regular expressions. The shell also expands regexs and changes the context
slightly. Is this a command line operation? For what it is worth, the *way*
over-simplified answer is a ^ at the beginning because that says not the
following however in certain cases it also means anchored to the start of a
line. Can you give more information?
