Unmount a device
umount [-f] path [path ...]
- Force an unmount, even if the device is busy.
- The root mountpoint to be unmounted.
This utility unmounts the devices that were mounted as the given paths.
If a device is busy (for example, if a file is open), umount fails. You can force the device to be unmounted by specifying the -f option.
