Hi,

I have provided the bash script below. Feel free to comment if you have any difficulties in understanding any part of the code.

#!/bin/bash
echo COMMAND MENU
echo
echo a. Current date and time
echo b. Name of the working directory
echo c. Contents of the working directory
echo
echo Enter a, b, or c:
  
read userInput

if [ $userInput = $"a" ]
then
date
fi

if [ $userInput = $"b" ]
then
printf '%s\n' "${PWD##*/}"
fi

if [ $userInput = $"c" ]
then
ls
fi

Sample output

Hope it helps!
