Delete Directories and its files that begin with the same character string

I wrote a shell script program that supposed to delete any directories and its files that begin with the same character string . The program is designed to delete directories and its files that are one day old or less and only the directories that begin with the same character string. The problem is the program doesn't delete the directories. I don't know why the script isn't working. The OS is Linux redhats. Version 6 x.

Here is the shell script


#!/bin/bash -x

NUMBER_OF_DAYS=1
MOUNT_PATH=/saswork

echo "Script Started"
echo "Deleting the files greater than ${NUMBER_OF_DAYS}"
cd ${MOUNT_PATH}
chmod 755 SAS_work*
find ${MOUNT_PATH} -mtime +${NUMBER_OF_DAYS} -name "SAS_work*"
find ${MOUNT_PATH} -mtime +${NUMBER_OF_DAYS} -name "SAS_work*" | while read DIR_NAME
do
	echo "Removing the ${DIR_NAME}"
	rm -rf "${DIR_NAME}"
done
echo "Script Completed"

Below are sample of the directories that the program should delete if the directories are one day old or less.

You cannot delete directories you do not have permission to delete (write permissions).

You are running your script as what user exactly?

Please post the exact command which includes the user prompt from your shell (in code tags).

Thanks.
