Dear Sir,
May I know how do I go about adding the following feature into the script below:
When user enter values other than 1,2,3,4,
a) Message “Wrong entry !!! Pls select 1,2,3 or 4” is displayed
b) The screen is cleared again and the menu is displayed.
I've tried adding * but it returns an syntax error.
Thank you.

Code:
#!/bin/bash
clear
var=1
until [ $var -eq 4 ]
do
echo "Menu"
echo "(1) Item 1"
echo "(2) Item 2"
echo "(3) Item 3"
echo "(4) Exit"
read -p "Enter your choice " var
clear
echo "Your choice is $var"
doneThank you.
