Help: How could i know i have installed a certain perl modules

[yjin6666]

Hi, everyone,

Does anyone here know how to check that a certain perl module has been
installed and how to test if it is working ok?

I am trying to install some perl modules on my redhad linux 9.0. But I
want to make sure these modules have not been installed before or they
are working well if installed.

Thanks for your help,

Kim

By simply using it.

To test if LWP::Simple is available:
perl -MLWP::Simple -le 'print "OK"'

Use CPAN.pm to install modules. It checks for modules already installed.
