+     The u\bum\bmo\bou\bun\bnt\bt command calls the unmount(2) system call to remove a _\bs_\bp_\be_\bc_\bi_\ba_\bl
+     _\bd_\be_\bv_\bi_\bc_\be or the remote node (rhost:path) from the filesystem tree at the
+     point _\bn_\bo_\bd_\be. If either _\bs_\bp_\be_\bc_\bi_\ba_\bl or _\bn_\bo_\bd_\be are not provided, the appropriate
+     information is taken from the fstab(5) file.
+
+     The options are as follows:
+
+     -\b-a\ba      All the filesystems described in fstab(5) are unmounted.
+
+     -\b-A\bA      All the currently mounted filesystems except the root are un-
+             mounted.
+
+     -\b-f\bf      The filesystem is forcibly unmounted.  Active special devices
+             continue to work, but all other files return errors if further
+             accesses are attempted.  The root filesystem cannot be forcibly
+             unmounted.
+
+     -\b-h\bh _\bh_\bo_\bs_\bt
+             Only filesystems mounted from the specified host will be unmount-
+             ed.  This option is implies the -\b-A\bA option and, unless otherwise
+             specified with the -\b-t\bt option, will only unmount NFS filesystems.
+
+     -\b-t\bt _\bt_\by_\bp_\be
+             Is used to indicate the actions should only be taken on filesys-
+             tems 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 _\bn_\bo_\bt be taken.  For example, the u\bum\bmo\bou\bun\bnt\bt command:
+
+                   umount -a -t nfs,mfs
+
+             umounts all filesystems of the type NFS and MFS.
+
+     -\b-v\bv      Verbose, additional information is printed out as each filesystem
+             is unmounted.
