MOUNT(1M)																 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

SEE ALSO
       mount(2), mtab(5)

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.
