Unmounting partitions

To remove a partition from a running system, the umount command is used and stands for unmount. The n seems to be thought about as being redundant so the term has been abbreviated to umount. It is very important to know that umount requires no files or directories that are being accessed or in use when detaching a partition from the system. Either the device node or the mount point can be used to unmount a partition, as shown here:

packt@PacktPublishing:~$ umount /dev/sdb1
