At IU, which systems have Perl?

At Indiana University, Perl is available on the research systems Quarry, Libra, and Big Red, and on the IU central web servers, Webserve and Mercury. Typically, the version available on these systems is some version of Perl 5. Perl 5 is also available via the Student Technology Centers Mac OS X machines.

On Quarry, Libra, and Big Red, Perl is in the /usr/bin/perl directory. On the other systems mentioned, it's in the /usr/local/bin/perl directory.

Note: On Mercury, the default Red Hat Enterprise Linux install of Perl at /usr/bin/perl will not be updated or have modules added to it. An up-to-date Perl installation is available at /usr/local/bin/perl.

Typically, this file will refer to Perl 5, though other versions of Perl will often be in the same directory. ( Perl 4 is no longer available on Webserve.) To find out if other versions of Perl are available, at the Unix prompt, enter:

If you want to find out if Perl is installed on a Unix system not mentioned above, enter one of the following:

Note: The availability of Perl on a system in no way indicates that it allows CGI or web page access.

For information about how to see which Perl modules are available on Webserve or Mercury, visit the IU Webmaster's perldoc perllocal page. (This page refers to Webserve, but the procedure it describes will also work on Mercury.)
