Displays "There are n arguments" if arguments were entered where n is the number of arguments.
Displays "The arguments are a, b, c" when arguments are entered and a, b, c are agrument1, argument2 etc.







Menu

a. Current date and time
b. Users currently logged in
c. Number of users logged in
d. Contents of current directory

Enter Choice..........




2. Write a shell script to implement the menu above. Call the script menu.sh

Execute the appropriate commands only when the user enters one of the menu choices. Display an error message such as "invalid choice" if the choice is not a, b,c, or d.
Remember that the read statement followed by a variable name will obtain input from the user.

Use the case structure to evaluate the choice entered.
