G'day kelscat18,

You're using a substitution (i.e. s/pattern/replacement/) when you really want a pattern match (i.e. /pattern/). You're also using the 'g' modifier, which is unnecessary here. Take a look at "perlretut - Perl regular expressions tutorial" to get an understanding of the basics. Here's how I might have coded that (which, I suspect, is close to what Corion had in mind):

#!/usr/bin/env perl

use strict;
use warnings;

my @tests = qw{jHj8nniO I87jjj8y jUjngnkk ikbHH 12345 !@$%^&*};
my @words = grep { /[A-Za-z]/ && /\d/ } @tests;
print "@words\n";

Output:

jHj8nniO I87jjj8y
