Robert's Perl Tutorial
Almost every Perl book is written for UN*X, which is a problem for Win32. This leads to scripts like:
#!c:/perl/perl.exe print "I'm a cool Perl hacker\n";
The function of the 'shebang' line is to tell the shell how to execute the file. Under UNIX, this makes sense. Under Win32, the system must already know how to execute the file before it is loaded so the line is not needed.
However, the line is not completely ignored, as it is searched for any switches you may
have given Perl (for example
-w to turn on
You may also choose to add the line so your scripts run directly on UNIX without modification, as UNIX boxes probably do need it. Win32 systems do not. We shall continue with the lesson.
