I think you can look up part two in Module::CoreList... part one follows (I have this in a file called "pm" and run it fairly frequently). `use strict; use ExtUtils::Installed; my $inst = new ExtUtils::Installed; my @mods = $inst->modules; my $max = 0; for (@mods) { $max = length $_ if length $_ > $max } open OUT, "\|less" or die $!; for my $m (@mods) { print OUT sprintf('%-*s', $max, $m), ' v', $inst->version($m), "\n +"; } close OUT;` [download] -Paul	[reply] [d/l]

First of all, your first question has come up on SoPW before. You could try doing a Super Search to find the answer. If you used a tool like `ppm` or `cpan` to install your modules, they might be able to tell you which modules they installed. You might be interested in Module::CoreList. It lists which modules are part of each version of Perl. Your distribution could have come with more than those modules, though. For example, ActivePerl includes libwin32, a library of Win32 modules.

From the command line, I use: `perldoc perllocal` to discover which modules have been installed. This not only tells you which version is installed, but also when it was installed. Where do you want them* to go today?*	[reply] [d/l]

Try the below code...it will list the modules installed in your machine. #!/usr/local/bin/perl use ExtUtils::Installed; my $instmod = ExtUtils::Installed->new(); foreach my $module ($instmod->modules()) { my $version = $instmod->version($module) \|\| "???"; print "$module -- $version\n"; }	[reply]
