NAME

       cpan-outdated - detect outdated CPAN modules in your environment

SYNOPSIS

           # print the list of distribution that contains outdated modules
           % cpan-outdated

           # print the list of outdated modules in packages
           % cpan-outdated -p

           # verbose
           % cpan-outdated --verbose
           .
           # ignore core modules (do not update dual life modules)
           % cpan-outdated --exclude-core

           # alternate mirrors
           % cpan-outdated --mirror file:///home/user/minicpan/

           # additional module path(same as cpanminus)
           % cpan-outdated -l extlib/
           % cpan-outdated -L extlib/

           # install with cpan
           % cpan-outdated | xargs cpan -i

           # install with cpanm
           % cpan-outdated    | cpanm
           % cpan-outdated -p | cpanm

DESCRIPTION

       This script prints the list of outdated CPAN modules in your machine.

       It's same feature of 'CPAN::Shell->r', but "cpan-outdated" is much faster and uses less
       memory.

       This script can be integrated with cpanm command.

PRINTING PACKAGES VS DISTRIBUTIONS

       This script by default prints the outdated distribution as in the CPAN distro format, i.e:
       "A/AU/AUTHOR/Distribution-Name-0.10.tar.gz" so you can pipe into CPAN installers, but with
       "-p" option it can be tweaked to print the module's package names.

       If you wish to manage a set of modules separately from your system perl installation and
       not install newer versions of "dual life modules" that are distributed with perl, the
       "--exclude-core" option will make cpan-outdated ignore changes to core modules. Used with
       tools like cpanm and its "-L --local-lib-contained" and "--self-contained" options, this
       facilitates maintaining updates on standalone sets of modules.

       For some tools such as cpanm installing from packages could be a bit more useful since you
       can track to see the old version number where you upgrade from.
