Nested case

kasparov29 · 12-02-2011, 05:35 PM

Hi there,

I have nested case in my script. I am asking user, want to continue? if user press y/Y then my inner case should continue, rather than that my code start from beginning. I would like to continue my inner case until user press n or N. Is any one tell me how can I do?

Thanking You,

Could you post your script so we can see what you did so far? By posting it for us, it will give us a better visual to work with, and we can gladly further assist from there.

Cheers,

Josh

Thanking You,

Make a loop.

Pseudocode

Code:

while(lowercase(ask_user("would you like to continue")) == 'y'){
   do_something();
}

echo "Do you want to do more? "

echo "Enter either "y or Y" to continue or "n or N" to exit."

read key

case "$key" in


[yY]) continue

;;

[nN]) exit ;;

esac 

}


while true

do

clear

echo "**************************************************** 

* Main Menu *

**************************************************** 

1. aaaaaaaaaa 

2. bbbbbbbbbbb

3. ccccccccccccc 

4. ddddddddd 

5. Quit. 

*****************************************************"

echo "Enter your choice: "

read choice


case "$choice" in 

1) some code

wantMore

;;
