UMOUNT(8) BSD System Manager's Manual UMOUNT(8)
umount -- unmount filesystems
umount [-fv] special | node
umount -a | -A [-fv] [-h host] [-t type]
The umount command calls the unmount(2) system call to remove a special device or the remote
node (rhost:path) from the filesystem tree at the point node. If either special or node are
not provided, the appropriate information is taken from the fstab(5) file.
The options are as follows:
-a All the filesystems described in fstab(5) are unmounted.
-A All the currently mounted filesystems except the root are unmounted.
-f The filesystem is forcibly unmounted. Active special devices continue to work, but
all other files return errors if further accesses are attempted. The root filesys-
tem cannot be forcibly unmounted.
Only filesystems mounted from the specified host will be unmounted. This option is
implies the -A option and, unless otherwise specified with the -t option, will only
unmount NFS filesystems.
Is used to indicate the actions should only be taken on filesystems of the specified
type. More than one type may be specified in a comma separated list. The list of
filesystem types can be prefixed with ``no'' to specify the filesystem types for
which action should not be taken. For example, the umount command:
umount -a -t nfs,hfs
umounts all filesystems of the type NFS and HFS.
-v Verbose, additional information is printed out as each filesystem is unmounted.

A umount command appeared in Version 6 AT&T UNIX.
