Question

I’m currently wrapping scripts with begin; rescue; end. Which works, but is annoying to un/comment at two different places and so on. Is there something like error_reporting(0); in PHP, but applied to the exit code and STDERR output?

Answer 1

You could try trapping the EXIT signal:

The special signal name “EXIT” or signal number zero will be invoked just prior to program termination.

Something like this should guarantee that your script always returns zero to the operating system:

Signal.trap('EXIT') { exit 0 }

For example, this script:

Signal.trap('EXIT') { exit 0 }
exit 1

actually returns zero to the OS despite triggering script’s termination with exit 1.
