Very basic example when checking if a variable has either values 'running' or 'exited': 1status='running' ## change to 'exited' and '' to see it works 2if [[ "$status" =~ running|exited ]]; then 3echo "Is either running or exited" 4else 5echo "Nope, I don't understand that status" 6fi See stackoverflow post
