What about nested shebangs?

[freethread]

I have a perl script that execute another script in javascript. To execute the javascript script I type:

 # jsexec.pl example.js

Ok, it works. Obviously the jsexec.pl has the shebang #!/usr/bin/perl. To have to type only the javascript script to run it on command line I added a shebang in example.js (and skipped it in perl parser) and chmod a+x example.js. The perl script jsexec.pl is in /root/bin so the shebang is #!/root/bin/jsexec.pl. It doesn't work and strange things happens.

I made two test scripts

[B]Perl script (sbang.pl)[/B]

   #!/usr/bin/perl

   use strict;
   use warnings;

   print ("--- sbang.pl ---\n\n");
   for (my $i = 0; $i < @ARGV; $i++)
   {
      my $sParam = $ARGV[$i];
      printf (" %04i - %s\n", $i, $sParam);
   }
   print ("--- end ---\n\n");

[B]Javascript script (sbang.js)[/B]

   #!/root/bin/sbang.pl

   printf ("%s %04X", "this is a test", scalar @ARGV);

Yes, in the javascript script file there is a perl instruction, executing it with

# sbang.js

the result is

Badly placed ()'s.

Searching on google/yahoo found no help.

Solved. Modified shebang in sbang.js to

#!/usr/bin/perl /root/bin/sbang.pl
