in reply to Nested foreach

Lowercasing each line is simple. $line = lc $line; tr/// works fine, too.

Put your ignore words in a hash, like so:

my %ignores = map { $_ => 1 } qw/bar foo baz quux/;

Then, as you read through the file break your $lines into $word's and:

next if $ignores{$word};

Hashes are fast and convenient. Use them.

    Functionally, yes. But, lc is self-commenting. tr is not. Use the self-commenting one.
