Unfortunately,
print if /O/;will also 'work' on your sample data, and for the same reason. zork42's post is probably the answer to your short-term problem; but rjt's links, and thinking carefully about why Laurent_R's post is almost certainly *not* what you're after would probably be a lot more useful to you in the long-term.
