Re: grepping a large file and stopping on first match to a list

[perlfan]

In practical terms, it would behoove you to pre-process the nearly 1 million lines of text ahead of time so you're searching over a much smaller set of possible matches.

If this is a relatively stable corpus of some kind, then there are any number of things you could do - use the commandline grep, throw it in SQLite/MySQL - or even better, Sphinx.

Once you do this, any suggestion you use in this discussion for efficiency in the Perl script itself will work even better for you.

Thanks! I'll look into it.
