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 direc‐
tory). 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 system previ‐
ously 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 systems 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
SEE ALSO

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.
