Creating nested menus in bash

rated 0 times [ 5] [ 0] / answers: 1 / hits: 6996 / 2 Years ago, wed, september 14, 2022, 5:34:59

I want to create more menus under option "a" when selected. If the user entered option "a" I want it to have a couple menus for you to select and for one of the options is to return to the "Main Menu". This is the 2 problems I'm having trouble with. I tried doing this same format I have below for the menu here and put it under "A" block of code but that didn't work.

#!/bin/bash



ok=0;



while ((ok==0))

do

echo "Main Menu:"

echo -e "	(a) More Menu Options "

echo -e "	(b) Exit"

echo -n "Please enter your choice:"

read choice

case $choice in

    "a"|"A")

    ok=1



    ;;

    "b"|"B")

    exit

    ;;

        *)

        echo "invalid answer, please try again"

        ;;

Why not put the same cycle inside?

#!/bin/bash



while :

do

echo "Main Menu:"

echo -e "	(a) More Menu Options "

echo -e "	(b) Exit"

echo -n "Please enter your choice:"

read choice

case $choice in

    "a"|"A")

    while :

    do

    echo "Secondary menu"

    echo -e "	(c) Print this menu again"

    echo -e "	(d) Return to main menu"

    echo -n "Please enter your choice:"

    read choice1

    case $choice1 in

        "c"|"C")

        ;;

        "d"|"D")

        break

        ;;

            *)

            echo "invalid answer, please try again"

            ;;

    esac

    done

    ;;

    "b"|"B")

    exit

    ;;

        *)

        echo "invalid answer, please try again"

        ;;

There is also select command which creates menus:

select i in ant bee cat

do 

    echo $i

    break

done

Let's run it:

$ select i in ant bee cat; do echo $i; break; done

1) ant

2) bee

3) cat

#? 2

bee
