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.
