Using variable in case statement
I want to do this: Code:
Ex 1: case $answer in 1|2|3|4|5) echo $answer;; x) break;; *) echo "Invalid selection. Try again.";; esac But I need the part "1|2|3|4|5" to be fetched from a variable, like so: Code:
Ex 2: case $answer in $cases) echo $answer;; x) break;; *) echo "Invalid selection. Try again.";; esac So if the input is 1-n, I want my program to execute (its not really echo I plan on executing, but I will send $answer as the action's input). Is that possible? What I really want to know is, can the number of cases be variable depending on when the script is run? If so, how do I achieve it? When written like in ex 2 my input is interpreted as * every time. I have also tried replacing "$cases" with "´echo $cases´" with the same result. The script is written in bash and runs on Sun Solaris 9. Last edited by fialia; 05-09-2008 at 12:08 PM..
