MOUNT(8) System Manager's Manual MOUNT(8) NAME mount, umount - mount and dismount file system SYNOPSIS /etc/mount [ special name [ fstype [ flags ] ] ] /etc/mount -a /etc/mount [ special name [ -r ] ] /etc/umount name /etc/umount -a DESCRIPTION Mount announces to the system that a removable file system of type fstype is present on the file special. The file name must exist al- ready; it becomes the name of the newly mounted root. Fstype and flags are integers; if omitted, they default to 0. Type 0 is an ordinary disk file system. Other types and possible flag values are listed in fmount(2). The shorthand mount special file -r is equivalent to mount special file 0 1: mount an ordinary file system read-only. If option -a is present, mount attempts to mount, in order, every file system listed in fstab(5). Umount announces to the system that the file system mounted on file name is to be removed. These commands maintain a table of mounted file systems in see fstab(5). If invoked without an argument, mount prints the table. If option -a is present, umount attempts to remove, in reverse order, each file system listed in mtab. Physically write-protected and magnetic tape file systems must be mounted read-only or errors will occur when access times are updated, even if no explicit write is attempted. EXAMPLES /etc/mount /dev/ra02 /usr Mount the file system on disk on directory /etc/mount /dev/null /proc 2 Mount the process file system. FILES mount table file system table SEE ALSO fmount(2), fstab(5), netfs(8) BUGS Mounting file systems full of garbage may crash the system. Mounting a root directory on a non-directory makes some apparently good pathnames invalid. MOUNT(8)
