little something i use (modification on original script from ltsp's
default scripts)
to clean the Desktop from redundant files every day.

i initiated all terminal's users to be pc1...pc72
( and so i have them under /home/pc* )

# find all of the subdirectories under /home
#getent passwd | cut -d: -f6 | while read U
ls -d /home/pc* | while read U
	# copy new-style Desktop
	if [ -d "$U"/ ]; then
		echo "clearing folder: $U"/Desktop
		ls --ignore='*.desktop' $U/Desktop | while read F
			rm -f $U/Desktop/$F
			echo "removing file: $U/Desktop/$F"


# also, remove data files from /home/pc* users (with special extentions)
find /home/pc* -maxdepth 2 \( -iname '*.mpg' -o -iname '*.avi' -o
-iname '*.wmv' -o -iname '*.exe' -o -iname '*.mpeg' -o -iname '*.rar'
-o -iname '*.mov' -o -iname '*.ram' -o -iname '*.ppt' -o -iname
'*.xls' -o -iname '*.doc'  -o -iname '*.od?'  \) -print0 | xargs
--no-run-if-empty --null rm -vf
