[K12OSN] Script to flush down the drain files from every user home...

Well, I'll start the discussion and let others refine it:


for line in $(cat /etc/passwd)
	user=$(echo $line | cut -d":" -f1)
	uid=$(echo $line | cut -d":" -f3)
	homedir=$(echo $line | cut -d":" -f6)
	if [ $uid -ge 500 ]; then
		echo "Deleting files for user $user"
		rm -rf $homedir/.g*
		rm -rf $homedir/.mozilla
		rm -rf $homedir/.cxoffice

#####  End of script  #####

This is just off the top of my head; it may have some egregious errors. It tries 
to only delete files in actual users' homedirs by only acting against those UIDs 
that are greater than 500, thereby missing the various system IDs.  Test it 
first on an inconsequential system, let others point out its flaws, YMMV, etc.
