MOUNT(8)                             BSD                              MOUNT(8)



NAME
     mount, umount - mount and dismount file system

SYNOPSIS
     /etc/mount [ special name [ -r ] ]

     /etc/mount -a

     /etc/umount special

     /etc/umount -a

DESCRIPTION
     mount announces to the system that a removable file system is present on
     the device special.  The file name must exist already; it must be a
     directory (unless the root of the mounted file system is not a
     directory).  It becomes the name of the newly mounted root.

     umount announces to the system that the removable file system previously
     mounted on device special is to be removed.

     These commands maintain a table of mounted devices in /etc/mtab. If
     invoked without an argument, mount prints the table.

     Physically write-protected and magnetic tape file systems must be mounted
     read-only or errors will occur when access times are updated, whether or
     not any explicit write is attempted.

OPTIONS
     -r        Indicates that the file system is to be mounted read-only.

     -a        If this option is present for either mount or umount, they
               attempt to mount or unmount all of the file systems described
               in /etc/fstab. In this case, special and name are taken from
               /etc/fstab. The special file name from /etc/fstab is the block
               special name.

               NOTE
               Apollo's implementation of the NFS (Network File System)
               protocol provides an NFS version of the mount command, which
               includes additional NFS options. Refer to the Domain NFS
               documentation for a description of the NFS mount command.

FILES
     /etc/mtab mount table
     /etc/fstab     file system table

BUGS
     Mounting file systems full of garbage will crash the system.
     Mounting a root directory on a non-directory makes some apparently good
     pathnames invalid.
