And I repeat, it doesn't. Windows looks up the association you defined and then goes through the %PATH% in your environment looking for the first perl.exe it can find. It doesn't even read the file, but passes it as a parameter to perl.exe. At that point, it is up to the Perl interpreter to decide what to do with that first line.

Then I am coming back to my 1st question . This path does not exist on windows "/usr/bin/perl " , how it works ? It doesn't. At least, it doesn't if you start the script from Windows. What Windows does is look up the extension, *.pl, in the Registry and launch the program associated with it. When it starts, perl will check the first line for any switches (options in UNIX talk) and sets them. However, some web servers read the the shebang line and executes what it says. So, you should change any Perl CGIs to point to the perl program. -- Just my 0.00000002 million dollars worth, Shawn Confusion is the first step of understanding.
