Answer 1

Here's a Perl one-liner that will print out a list of installed modules:

perl -MExtUtils::Installed -MData::Dumper -e  'my ($inst) = ExtUtils::Installed->new(); print Dumper($inst->modules());'

Just make sure you have Data::Dumper installed.

Try "perldoc -l":

$ perldoc -l Log::Dispatch /usr/local/share/perl/5.26.1/Log/Dispatch.pm

Answer 4

Here's a really hacky way to do it in *nix, you'll get some stuff you don't really care about (ie: warnings::register etc), but it should give you a list of every .pm file that's accessible via perl.

for my $path (@INC) {
    my @list = `ls -R $path/**/*.pm`;
    for (@list) {
        s/$path\///g;
        s/\//::/g;
        s/\.pm$//g;
        print;
    }
}

For Linux the easiest way to get is,

dpkg -l | grep "perl"
