How to get Perl version number DateTime :: Format :: DateManip from command line?

Question

I use this from the command line:

perl -MDateTime::Format::DateManip -le 'print $Some::Module::VERSION'

but only returns an empty string, any thoughts?

Answer 1

This is pseudo code, Somenot set, so it just prints undefwith a flag -l, for example perl -le'print undef;

Confirm alerts with -w

$ perl -MDateTime::Format::DateManip -wle 'print $Some::Module::VERSION'
Use of uninitialized value $Some::Module::VERSION in print at -e line 1.

Replace with the Some::Modulemodule you want to use.

Also, just for fun;)
