Days13 module version

How do I get installed cpan module? cpanminus and cpan is install command.

I like:

$ yum list

$ gem list

perl – How do I get a list of installed CPAN modules? – Stack Overflow
perlfaq3 – perldoc.perl.org

$ perldoc [modulename]

No doc mean no installed module. Boo.

Now I see:
