The First Line of a Perl Script
The First Line of a Perl Script
-
Since PERL is an interpreted language,
the first thing that a Perl script must do is reference the location of
the Perl Interpreter that is used to execute the script
-
To do so, you will typically use the following syntax:
#! /pathname/name_of_perl_executable
The "#!" is a shell scripting command used to say that the file should
be considered an executable file and that it should be executed using the
specified interpreter.
Typically, the Perl interpreter will be located in either "/usr/local/bin/"
or "/usr/bin".
Thus, the first line of a Perl CGI script will usually look like one of
the following lines
#! /usr/local/bin/perl
or
#! /usr/bin/perl
Of course, the easiest thing to find out what the first line of your CGI
script should look like is to send an email to your sysadmin asking!
