Using Linux scripting write a program which receives a directory name as its only parameter. If it does not receive a parameter or receives more than one, output an error. Otherwise, iterate through the contents of the directory and count and output the number of items in the directory that are regular files, that are directories, and that are links. To indicate the items in the directory in your for loop, use either $1/* or `ls $1/*` as the list to iterate over. Also output the total number of items found in the directory. Run this script on several directories like /etc, /bin and ~, ~/new and ~/scripts.
