A nice, robust way to do it is with Getopt::Long (http://search.cpan.org/~jv/Getopt-Long-2.35/lib/Getopt/Long.pm) but an easier, faster way is by passing it arguments on the command line like this:

iw-home/iw-perl/bin/iwperl

If you have the option to do so - I'd recommend making the second script a module and calling the subroutines or methods directly from the first script so as to avoid the overhead of invoking a second shell process to run the second perl script.

Otherwise - Getopt::Long (as Dave posted), Getopt: Smiley Frustrated

td, and any number of other similar modules exist to help parsing command line arguments, once parsed and stored they can be accessed again to form the second command line invokation. A lot depends on how you distinguish the command line arguments that are used by the first script from those that are used by the second script (are they mutually exclusive, exactly the same - just passed through, or somewhere in between?)

You should certainly consider this if performance is an issue. If this is a one time call, then no big deal. However if this is something run often (i.e. in a workflow or a TPL) then the overhead of starting a new perl environment it high and a module will perform much better.
