# Purpose: This scrip is in esscence a wrapper to rm. It detects whether the file the user is trying to delete is a file, an empty directory, a non-empty directory or a file/directory that you do not own.
# This script will prompt the user when the user does not have write permissions to the file/folder or when it is a non-empty directory. It also prints out a list of removed files/directories upon termination.
