Managing pacsave and pacnew files

Question

Sometimes it is a while before I do another 'pacman -Syu' ... so when I do I might find myself with a few .pacsave and .pacnew files to manage. To help myself deal with them I have written two simple little scripts to check and compare them quickly from the command line. I named the scripts diff_pacnew.sh and diff_pacsave.sh - and offer them here thinking it might be of interest to and maybe useful for forum members.
They use 'diff' to compare the existing file with the new one and prompt to enter a comment (such as "delete pacsave" or "add xyz to the file"). The comments are saved in /tmp/diff_pacsave.txt and /tmp/diff_pacnew.txt so I don't need to remember everything. I just read the txt files and alter/replace/remove the pacsave/pacnew files according to my notes there.
They use the 'locate' tool so I run 'updatedb' before using them.
#!/bin/bash
# diff_pacsave.sh
# script used in Archlinux
# to compare configuration files with their updated versions
for i in `locate *.pacsave`
do
j=`echo $i | sed 's/.pacsave//'`
if [ -f $j ]
then
echo "...................."
echo "comparing $i with $j"
diff $i $j
echo "Enter notes"
read notes
echo "$j" >> /tmp/diff_pacsave.txt
echo "$notes" >> /tmp/diff_pacsave.txt
echo >> /tmp/diff_pacsave.txt
echo
fi
done
#!/bin/bash
# diff_pacnew.sh
# script used in Archlinux
# to compare configuration files with their updated versions
for i in `locate *.pacnew`
do
j=`echo $i | sed 's/.pacnew//'`
if [ -f $j ]
then
echo "...................."
echo "comparing $i with $j"
diff $i $j
echo "Enter notes"
read notes
echo "$j" >> /tmp/diff_pacnew.txt
echo "$notes" >> /tmp/diff_pacnew.txt
echo >> /tmp/diff_pacnew.txt
echo
fi
done

Thanks jason.
Hey Xyne, so i renamed my crond.pacnew to crond (there was no crond before).  I don't really know if i need it. I've never messed with it before.
Mine looks like this:
/var/log/crond.log {
   sharedscripts
   copytruncate
   missingok
   postrotate
       kill -HUP `cat /var/run/cron.pid`
   endscript
and it's in the /etc/logrotate.d/ directory.  Think I may need it? I have no idea what that stuff means. hehe I just started using Linux just over a month ago with Arch! wooo!!
