These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree. Conversely, the umount 8 command will detach it again. The standard form of the mount command, is mount -t type device dir This tells the kernel to attach the file system found on device which is of type type at the directory dir.

The previous contents if any and owner and mode of dir become invisible, and as long as this file system remains mounted, the pathname dir refers to the root of the file system on device. Three forms of invocation do not actually mount anything: The option -l adds the ext2, ext3 and XFS labels in this listing.

The call is mount --bind olddir newdir After this call the same contents is accessible in two places. One can also remount a single file on a single file. This call attaches only part of a single filesystem, not possible submounts.

The call is mount --move olddir newdir Since Linux 2. A shared mount provides ability to create mirrors of that mount such that mounts and umounts within any of the mirrors propagate to the other mirror. A slave mount receives propagation from its master, but any not vice-versa.

A private mount carries no propagation abilities. A unbindable mount is a private mount which cannot cloned through a bind operation. The customary choice none is less fortunate: For example, in the case of an NFS mount, device may look like knuth. This file is used in three ways: Adding the -F option will make mount fork, so that the filesystems are mounted simultaneously.

However, when fstab contains the user option on a line, anybody can mount the corresponding system. Only the user that mounted a filesystem can unmount it again. If any user should be able to unmount, then use users instead of user in the fstab line.

The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e. The group option is similar, with the restriction that the user must be member of the group of the special file. If no arguments are given to mount, this list is printed.

The former has somewhat more information, such as the mount options used, but is not necessarily up-to-date cf. OPTIONS The full set of options used by an invocation of mount is determined by first extracting the options for the file system from the fstab table, then applying any options specified by the -o argument, and finally applying a -r or -w option, when present.

Options available for the mount command:Note that if you mount your ntfs drive using a label and wish to be able to change the permissions of directories or files on this drive then the following works well (edit the /etc/fstab e.g.
