I tried doing that, btw thank you for taking the time, but it just keeps saying something things in the terminal saying ive dont have permission e.g.
chmod a+x
usage:chmod [-fhv] [-R [-H | -L | -P]] [-a | +a | =a [# [ n]]] mode|entry file ...
chmod [-fhv] [-R [-H | -L | -P]] [-E | -C | -N | -i | -I] file ...
