I replied to the other thread before I saw the double post (my answer was confused, to boot). But, I figured I'd use this as a good time to learn about lookaheads:

my @lines = ( q(String), q(I have a String), q(I have a String and a .c), q(I have a String.c), q(String.O) ); foreach (@lines) { #Look for String, not followed by .c, .o next unless /String(?![.][coCO])/; print $_ . "\n"; } Output: String I have a String I have a String and a .c

I have to get less lazy about learning new facets of Perl, it is always much less painful/time-consuming to get a grasp of the basics than I think it is going to be.
