How does one find out what perl modules are installed?

perl - what?

Thanks!

Hi,

Typing "perl -V" at a shell prompt will also show you the @INC
directories where perl looks for modules and you can "ls" in those
locations for more information.

No option for that. Best guess is to do

# man perllocal

or

# perldoc local

The latter is (far) more accurate.

This is however no guarantee that the modules installed are still there, because there is no (consistent) way to uninstall modules in perl.

This is also no guarantee to be a *complete* list, since some modules are installed outside of the default perl tree to allow multiple versions living together and depend on $PERL5LIB. Mainly applied to DBD::* where there are multiple database versions on the system that each need their own version of the same module.

If you want a complete list of available modules, either core, or later added, do

# perl -MFile::Find -le'find(sub{/\.pm$/ and$pm{$File::Find::name}++},@INC);print for sort keys%pm'

This also includes all (sub)module files that are included in larger modules like Tk or DBI

Enjoy, Have FUN! H.Merijn
