Or just:

print( "$1\n" ), exit if /.../;

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)

In the absence of evidence, opinion is indistinguishable from prejudice.

Yes, except it's printing to STDERR not STDOUT. Far more than you ever wanted to know about shell redirections That's complicating things if sh has to capture the output. No, only that way allows to cleanly separate usable data (STDOUT) from error messages (STDERR), without having to use heuristics (in other words: automated guessing).
