sh screen - Wait for screen to terminate

Question

I'm writing on a little script that does send a command to a running screen session. This command stops the screen but not instantly. I need to wait for it to finish in order to continue with the rest of the script.

This is how I stop the screen:

screen -S $SCREEN_NAME -p 0 -X stuff "`printf "stop\r"`"

How could I do this?

I found an solution:

You just simply check if the screen is still running and wait (sleep) for one second.

Like this:

while screen -list | grep -q $SCREEN_NAME
do
    sleep 1
done
