Nowadays normally Ubuntu mounts external hard drives without the executable bit set as a precaution against dangerous scripts from running automatically. Without the executable bit set it becomes impossible to run scripts from external hard drives. However, setting the executable bit is not as hard but little bit laborious. So I wrote a small script to decrease the load.
