Re: regexp match large file

What's the easiest way to match regexp in an entire .txt file against a
set of keywords?

For example, a script that would search an e-mail for the words "hello"
"computer" "johnny" and then return the results?

Sorry if this question is a bit obtuse, I merely exploring an idea...
Thanks.

You could load the whole file into a string and go from there or, if it
is a big big file, read it in one line at a time.

As far as the matching part, I have asked for help on this topic in the
past so maybe a few links to recent discussion might help:

$ grep 'hello|computer|johnny' e.mail

Or:

$ for w in hello computer johnny; do grep $w e.mail; done
