MOUNT(8) 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. The optional argument -r
indicates that the file system is to be mounted read-only.
Umount announces to the system that the removable file sys-
tem previously mounted on device special is to be removed.
If the -a option is present for either mount or umount, an
attempt is made to mount or dismount each of the file sys-
tems named in /etc/fstab. The special file name from
/etc/fstab is the block special name.
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.
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.
These commands deal only with filesystem type 0. They
should be made more general.
