The following lines creates an auditWorldFile.log log file which will

#!/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;
