From the sound of it what you want is in-place-editing:

The code above will read in any number of files modifying "this" to
"that" in each one.


Doesn't that code empty out a file? That is, isn't there a key line
missing:

#!/usr/bin/perl -i
use strict;
use warnings;

while (<>) {
s/this/that/;
print;
}

I apologize if "print;" was so obvious that it didn't even need to be
mentioned, but to be honest, I tried it without that line and emptied a few
test files before I got it right.
