Or just: `print( "$1\n" ), exit if /.../;` [download] Or even: `die "$!\n" if /.../;` [download] Which seems to capture the semantics perfectly.

> Which seems to capture the semantics perfectly. Yes, except it's printing to STDERR not STDOUT. That's complicating things if sh has to capture the output. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply]

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).
