mount, umount − mount and dismount file system
/etc/mount [ special name [ −r ] ]
/etc/umount special
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.
/etc/mtab: mount table
mount(2), mtab(5)
Mounting file
systems full of garbage will crash the system.
Mounting a root directory on a non-directory makes some
apparently good pathnames invalid.
