in reply to remove lines matching list of strings
The fastest way? If you're on a unix box, I'd try using grep. It's specialized for that sort of task.
If you just want to do it with perl, I think reading the entire file into a scalar and then building the giant regex may be the fastest. But you may want to use Benchmark and test to find out what's fast or not.
