22.2.3 Switches On the "#!" Line
When you make a script executable, in order to make it usable as a
command, the system will pass switches to perl from the script's #!
line. Perl checks that any command line switches given to a setuid
(or setgid) script actually match the ones set on the #! line. Some
Unix and Unix-like environments impose a one-switch limit on the #!
line, so you may need to use something like
-wU instead of
under such systems. (This issue should arise only in Unix or
Unix-like environments that support #! and setuid or setgid scripts.)
