If you have control over the second script make it what "Effective Perl Programming (second edition)" calls a modulino - a module that can be run as a script or used as a module. Consider:

use strict;
use warnings;

package Demo;

sub run {
    print "Hello world\n";
}


run (@ARGV) if ! caller ();

1;

which executes the run sub when run from the command line, or can be used in another script where you can call Demo::run () to have the same effect as running it from the command line, but with the advantage that it is now trivial to pass and return data.

True laziness is hard work
