Trouble in getting user input while using CASE statement in UNIX
i want to get user input like this
please tell which option to chose
1. mango 2. tango 3. rango
if user chooses mango
then it should execute a set of statements and again ask like this
what do you want to do
1.add 2.subtract 3.exit
when i choose exit it should goto my previous menu asking again (please tell which option to chose
1. mango 2. tango 3. rango )
i have did coding to an extent like this
As you can see first it will ask me to choose from 6 options
1. mango 2. tango 3. rango 4.exit
. If for example if i chose 1. mango
then it will ask
1.add 2.subtract 3.exit
now if i chose exit . it should go back to main menu (THIS IS WHAT IAM NOT ABLE TO DO) and ask
1. mango 2. tango 3. rango 4.exit
if i give exit here then only script should exit.
Please help how to do this one in the existing scrit. if not possible then modify and do in whicvere way u wish to do to to get the final result. I have just put an skeleton overview of the script. If anyone have any better approach on this then please advice as to how to arrive to this solution.

The ;; are in the wrong place, they should be after the fi which terminates your if statement. In a case statement the ;; terminates each separate condition.
Quote:
*) echo "please enter correct value" read ;;
break;;
The last two lines are a bit iffy. Probably best to just output an error message because the script is going to ask the question again on the next iteration of the "while true" loop (if you move the question to within the loop). Also, lose the break;; line because it is totally out of context.
Add the "esac" to complement the original "case".
Add the "done" to complement the original "do".
The initial question to populate $answer should probably be inside the do-done loop or the users will neve get the chance to change the value.
I'm having an issue with bash read input when using a case statement.
The script halts and doesn't read the input on the first loop. if I hit enter then the scripts starts to respond as expected. Need some help here.
