Does one string always preceed the other string? Or can they be in any order?

If I've got my head screwed on correctly (always a doubtful proposition,) some of the solutions above will work in both cases and other solutions will only work if $string1 appears before $string2.

From ikegami's post:

Works in any order

@interesting_lines = grep /$string1/, grep /$string2/, @log;

Works in any order

@interesting_lines = grep /$string1/ && /$string2/, @log;

[download]

Only works if $string1 preceeds $string2

@interesting_lines = grep /^(?=.*$string1)(?=.*$string2)/, @log;

[download]

Or am I a total moron?
