GNU has no simple regex support. Actually, neither did Jamie's by the time I did that test, but I added the -E flag to make it obvious what was going on. :) I rather hope that the rumoured newer version of H. Spencer's regex lib is faster... Being as slow for that pattern as it is has got to be a bug of some sort... It's actually faster to scan the file twice, once for the first string and then for the second. -- This is my .signature which gets appended to the end of my messages.
