Hi summer_cherry,

Thank you very much for the code.

I have written small shell scripts using basic commands, hence my expertsie in Unix shell is limited.

Could you please let me know what should be passed to <Data> in while loop. I assume it should be input file. I tried passing that, but program did not work.

I know, i am missing something here. It would be really great if this script can be changed by substituting with right values for <Data> and so on.

Thanks.
Venkat

        $tmp[$i-1] =~ s/(^"|"$)//g;
        $tmp[$i-1] =~ s/""/"/g;
        print "Field($i+1):$tmp[$i-1]\n";
    }
    print "\n";
}

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.
