Is there a command to show all Perl modules installed on a system?

    You should find that on most systems that: 

       perldoc perllocal

    [download]
    will show all the modules other than from the core that are installed.

    How about this one:

    perl -MFile::Find -le '
    for my $inc (@INC) {
        find(sub {
                   return unless /pm$/;
                   $_ = $File::Find::name;
                   s{^\Q$inc/}{};
                   s{/}{::}g;
                   s{.pm$}{};
                   print
                 },
                 $inc);
    }'

    We'll see how long it takes to get golfed. :-)

      revdiablo, 
      use ExtUtils::Installed;
print "$_\n" for ExtUtils::Installed->new()->modules;

    I've always been fond of
      perldoc -t perllocal | grep Module | cut -d\" -f 3 | sort | uniq
    with maybe a | vgrep tacked on for fun.
