Grep understands the '^', so egrep is not needed.  Typically, you only
need egrep for patterns that involve alternative re's, like looking
for one of "abc|def|ghi" which grep does not recognize.

Also, it might be helpful to trim your replies so we don't need to
wade through the whole thread to see your reply.
