MOUNT(1M)

NAME
mount, umount - mount and dismount file system

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

/etc/umount special

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 last argument indicates that the file system is to be mounted read-only.

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. 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

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.
