Do we need to install Perl on Unix Server?

I have a CGI Script written in Perl which resides on a Unix Server. Do I need to install Perl seperately into the server or is it there by default? Please Clarify.

If you could provide us which specific UNIX, we may then have a clue if Perl is installed by default.

What server? A webhost server? If they run a webhosting company, they should have Perl installed. You should ask your webhost for such question anyway.

Open a shell window and without the quotes type "whereis perl". If perl is already installed and is residing in your path, you should see one or more directory paths appear(i.e. /usr/bin/perl). If this were the case then the first line of your scripts would read #!/usr/bin/perl. If not, that doesn't mean it's not installed. This is just one quick check.

If you determine that Perl is installed on the server using the "whereis Perl" command in a telnet session, you will also need to know what modules are installed on the server. Best script I've found for this is Perldiver available at http://www.scriptsolutions.com.
