linux::distribution::packages
Linux::Distribution::Packages(3pm) User Contributed Perl Documentation Linux::Distribution::Packages(3pm)
NAME
Linux::Distribution::Packages - list all packages on various Linux distributions
SYNOPSIS
use Linux::Distribution::Packages qw(distribution_packages distribution_write);
$linux = new Linux::Distribution::Packages({'format' => 'csv', 'output_file' => 'packages.csv'});
$linux->distribution_write();
# Or you can (re)set the options when you write.
$linux->distribution_write({'format' => 'xml', 'output_file' => 'packages.xml'});
# If you want to reload the package data
$linux->distribution_packages();
DESCRIPTION
This is a simple module that uses Linux::Distribution to guess the linux distribution and then uses the correct commands to list all the
packages on the system and then output them in one of three formats: native, csv, and xml.
Distributions currently working: debian, ubuntu, fedora, redhat, suse, gentoo, slackware, redflag.
The module inherits from Linux::Distribution, so can also use its calls.
EXPORT
None by default.
TODO
* Add the capability to correctly get packages for all recognized distributions. * Seperate out parsing from writing. Parse data to hash
and give access to hash. Then write the formatted data from the hash.
