#!/bin/sh

#variables
# this set the delimiter to be a carriage return ONLY instead of space
plus carriage return -
#so we can handle items with a space in  the name
oldIFS=$IFS
IFS="
"
SUBDIR=$(find . -maxdepth 1 -type d)

for DIRS in $SUBDIR
 do
    # your thing
    echo "Thrashing $DIRS in $SUBDIR"
 done

#cleanup!!
IFS=$oldIFS
