I have recently been checking out various systems to find out what versions of Perl modules are installed on them, and this can get a little tedious if you do this the usual way, which for me at least is a command using perl -M ...
I found the following nice little program on perlmonks which really improves the situation quite a bit. It not only shows you which version you have installed, it shows the most recent version available from CPAN. http://www.perlmonks.org/?node_id=37237 #!/usr/bin/perl use CPAN; printf("%-20s %10s %10s\n", "Module", "Installed", "CPAN"); foreach $a (@ARGV) { foreach $mod (CPAN::Shell->expand("Module", $a)){ printf("%-20s %10s %10s %s\n", $mod->id, $mod->inst_version eq "undef" || !defined($mod->inst_version) ? "-" : $mod->inst_version, $mod->cpan_version eq "undef" || !defined($mod->cpan_version) ? "-" : $mod->cpan_version, $mod->uptodate ? "" : "*" ); } } And so when I run as follows... [EMAIL PROTECTED] ted]# perl version.pl CGI WordNet::Similarity WordNet::QueryData Text::Similarity WordNet::Tools I get the following nice little report... Module Installed CPAN CGI 3.10 3.37 * WordNet::Similarity 2.04 2.04 WordNet::QueryData 1.47 1.47 Text::Similarity 0.02 0.06 * WordNet::Tools 2.04 2.04 Very useful I think...
