To get this to work in cron you need to make sure that the script is executable. Assuming the script is called "boyt.bash" and is in your own bin directory "/home/apcr/bin/boyt.bash".

chmod +x /home/apcr/bin/boyt.bash

Check that is runs by just typing:
/home/apcr/bin/boyt.bash

After that it should run in cron.
