List installed modules:

Pick one :)

• perl -V
• perldoc <module name>
• perldoc perllocal
• instmodsh
• cpan -[l,a]

or:

perl -e 'use ExtUtils::Installed; foreach (ExtUtils::Installed->new()->modules()) {print $_ . "\n";}'

Install modules in homedir:

• install “local::lib” module
• print settings: perl -Mlocal::lib
• add to .bashrc: eval "$(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)"

Then there’s also “Perlbrew“.
