You can put any path in that line, not only /usr/bin/perl.
If you are using Perl under Windows, you may want to put paths like:
#!C:/perl/bin/perl
#!C:/perl/bin/perl.exe
If a Perl program uses this line under Unix/Linux and if the program is
executable, it can be ran by just using:
./program_name
without needing to use
perl program_name
Under Windows it doesn't help that line at all if you just need to run the
programs from a command line.
But it can help you if you need to run Perl programs as CGI scripts with
Apache.
I have Apache installed on E: drive and Perl on the same drive in the folder
e:\usr
and in this case I can use
#!/usr/bin/perl
as the first line in CGI scripts
(although I haven't used CGI scripts for years:)

Subject: 1st line of perl script
Hi All
Perl script works without the first line ( perl Interpreter
: #! /usr/bin/perl) . What is the real use of this line ? This line does
not through any error on Windows where , this path does not exist .
Why is it so ?
Could anybody explain it clearly?
Thanks
