Subject: negative grep

A bit of syntax that I have never picked up.  How do I use grep to exclude 
entries in a list?

biglist.grep(/foo/)	# get all entries containing foo
biglist.grep(????)	# get all entries that do not contain bar

It's not what I know that counts.
It's what I can remember in time to use.
