[BRLTTY] OT: dumbduumb search question using `less'

[Lee Maschmeyer]

Duh, hi folks,

I've got a directory containing upwards of 500 print books. I want to
check the accuracy (I'm pretty sure it is) of the rule that says in
grade 2 to spell out the string agery at the end of a word:

endword agery =

I have a script to scan all these print books for strings, so I told
it to scan for agery, piping the result through `less'. I've got 553
lines containing this string.

Most of the words are either "savagery" or "imagery". I want to search
for lines containing neither of these. How can I do it? 

I can scan for !savagery and it finds imagery, or !imagery and it
finds savagery. But I can't get the "and" in there.

I've tried to use regular expressions and would think that something
similar to:

/[^\(savagery\)]&&[^\(imagery\)]

would work, but so far I haven't hit on the right combination and I've
tried 15 or 20 or more different patterns. Any ideas?

To reduce clutter, please test suggestions to verify them. Thanks a
lot,
