Bash scripting: how to get the name of an element in a radio sheet using a dialog

Question

I need to make a radio sheet in a bash script using a dialog interface, for example, if I have the following list:

dialog --backtitle "OS infomration" \ --radiolist "Select OS:" 10 40 3 \ 1 "Linux 7.2" off \ 2 "Solaris 9" on \ 3 "HPUX 11i" off 

I want that when the user selects an option and click OK, my scripts read the element name (and not the position number).

Maybe? Thanks!

You can put the expected results in an array:

 array=(Linux Solaris HPUX) var=$(dialog --backtitle "OS infomration" \ --radiolist "Select OS:" 10 40 3 \ 1 "Linux 7.2" off \ 2 "Solaris 9" on \ 3 "HPUX 11i" off >/dev/tty 2>&1 ) printf '\n\nYou chose: %s\n' "${array[var - 1]}"
