  14 # $chosen:
  15 # - awk first variable must contain digit (dont print /dev/sda )
  16 # - and forth variable contains /mnt (means is mounted at /mnt)
  17 # - for android case we find in /mnt for android* not empty directories
  18 #      this is not perfect solution to find mounted android devices.
  19 # - if nothing is chosen exit 0
