Then give the user an option to continue with a new search or exit.

Explanation / Answer

Hi. I have done the first part. I am unable to understand the options after the firstc hoice is made. Can you please re-explain it? However, you can easily replicate the code for menu based choices, but you can certainly tell me the part 2.

#!/bin/bash
# Menu Based Script

PS3='Enter the desired memory size: '
options=("1) 8 MB" "2) 16 MB" "3) 32 MB" "Quit")
select opt in "${options[@]}"
do
case $opt in
"1) 8 MB")
echo "Here do your action for choice 1"
;;
"2) 16 MB")
echo "Here do your action for choice 2"
;;
"3) 32 MB")
echo "Here do your action for choice 3"
;;
"Quit")
break
;;
*) echo invalid option;;
esac
done
