Re: [gentoo-user] Remove redundant entries in "world" - howto

[Pau Peris]

The following lines creates an auditWorldFile.log log file which will
show packages requires by other packages, so theones you can safely
remove.


#!/bin/bash

n=`wc -l /var/lib/portage/world|awk '{ print $1 }'`;
for i in `seq 1 $n`;do
        pkg=`cat /var/lib/portage/world|head -n$i|tail -n1`;
        echo -e "Packages depending on $pkg." >> /tmp/auditWorldFile.log
        equery d $pkg >> /tmp/auditWorldFile.log
        echo -e "" >> /tmp/auditWorldFile.log
done;
