Question

In Linux, write a bash script named dlist that takes one argument, either a d, or an x, or an nx. If no argument or more than one argument is given, then print an error message, such as "incorrect number of arguments". If the argument is 'd', then dlist lists all of the directories within the current directory. If the argument is 'x' then dlist lists all of the ordinary, executable file (not directory). If the argument is 'nx' then dlist lists all of the ordinary, non-executable files in the current directory.
