There are many ways to do this, but one option would be to have a file called ~/res.cfg containing, for example
RES=480

Open in new window

then the code would become
rez=$(awk -F= '$1 ~ /^RES$/{print $2}' ~/res.cfg)
    case $rez in
        480* )  python ./files/SD.py;;
        720* )  python ./files/HD.py;;
        1080* ) python ./files/FHD.py;;
        * ) echo "Bad response $rez"; exit 1;;
    esac

Open in new window

I've taken out the while loop, because you only want to check the configuration file contents once (so the "break" commands are no longer needed).  I've also exited the script if the configuration item is wrong.

The square brackets in your case statement are wrong - for example, "[480]*" here will match a 4, an 8 or a 0, followed by any characters (so any of 480, 800, 8, 0abc etc).  you just need the bare text.

There are simpler ways to store the configuration information (e.g. just have the actual value, such as "480"), but this method allows for other configuration items to be stored in the same file, if you need them in the future.
