You are right, of course. I never use anything but $!, so I had forgotten this. The OP error output seemed to indicate that $ERRNO was blank. I was unsure as to why, or whether he simply omitted it. At any rate, it looks like his problem was fixed by changing the params to unzip fnord	[reply]

Another check of the unzip man page yields the likely reason for your problem. Closing a pipe causes the writer (unzip in this case) to receive SIGPIPE. unzip subsequently returns a non-zero exit status (sets $? to SIGPIPE, or 13), which may be causing croak to fire. You may want to change you logic to not croak if the close fails, but $? is set to 13 fnord	[reply]
