how to know if a module is already loaded?

How do I test if a particular module is loaded on my system?

That depends on how you interpret that question:

To test whether a module has already been loaded into an application,
consult the %INC hash (where the keys are module_names mangled with
{ $module_name =~ s|::|/|g; $module_name .= '.pm'; } and the value
are the full path to the module).

To test whether a module has been installed, enter

% perl -M<module> -e 1

If you get "Can't locate <module>.pm in @INC (@INC contains ...)"
the module is not installed.

cu,
Martin
