/scripts/checkperlmodules
To list all Perl modules and put them into a file for easy searching.
perl -MFile::Find=find -MFile::Spec::Functions -Tlwe 'find { wanted => sub { print canonpath $_ if /\.pm\z/ }, no_chdir => 1 }, @INC' > Perlmodules.txt
Then if you wanted to find the imagemagick perl module do the following.
cat Perlmodules.txt |grep -i imagemagick
