Hi adamZ88, Sorry, there was an error in the version I posted with a missing set of parens in one line. Should be: ( my $name = $ARGV[0] ) && length $ARGV[0] > 2 or die "Usage: `$0 <nam +e>` (min. 3 letters)"; [download] ( Without the parens, `$name` was assigned the value of `$ARGV[0] && length $ARGV[0] > 2`, which is 'true', or, literally, `1` ... which is why you got those weird matches.) The way forward always starts with a minimal test.	[reply] [d/l] [select]
