Calling Perl from a shell script, how do I pass a return value from Perl to the shell?

I'm successfully calling a Perl script from a shell scrip开发者_开发问答t. Now I want to pass a return value from the Perl script indicating whether it was successful or not to the shell script. How would I go about doing this?

Simply exit the Perl script with the appropriate exit value.

exit $exit_value;

exit 0;

if ($problem) { exit 1 }

In the shell script you'll have the usual $? to check the return value.
