How do you list modules already installed?
There's no definitive way to do this. If you just want to see if you have the Foo::Bar module, you can use "perl -MFoo::Bar -e 1" and if you get an error then you need to install Foo::Bar.
You can also try the following script which uses the ExtUtils::Installed module, but I have found that its output is sometimes misleading, in that it will not display base (stock included) modules. And I'm not sure if it knows about modules that are installed through means other than CPAN (e.g. through your distro's package manager.)
#!/usr/bin/perl
use ExtUtils::Installed; my $instmod = ExtUtils::Installed->new(); foreach my $module ($instmod->modules()) { my $version = $instmod->version($module) || "???"; print "$module -- $version\n"; }
