mount -- Command Mount a file system /etc/mount [ device directory [ -ru ] ] The command mount mounts a file system from device onto directory. In effect, it grafts the root directory of file system on device onto directory. If you invoke mount without any arguments, it displays information about the file systems that are now mounted. If you use option -r, mount mounts the specified file system in read-only mode. This is useful if you wish to read a file system without changing it in any such way, such as when you are backing it up. Note, however, that when a file system is mounted in read-only mode, COHERENT does not update file-system information, such the time a file was last accessed. The option -u tells mount to write an entry into the mount-table file /etc/mtab without actually mounting the file system. When this is done, COHERENT will hereafter mount the file system automatically whenever you boot COHERENT. Please note that unlike every other COHERENT or UNIX command ever devised, mount requires that its options follow the file names, rather than precede them. The COHERENT version of mount follows this convention in order to conform to this established UNIX practice. To un-mount a file system, use the command umount. (NB, this is not a typographical error -- this command's name contains only one `n'.) The script /bin/mount calls /etc/mount, and provides convenient abbreviations for commonly used devices. For example, mount f0 executes the command: /etc/mount /dev/fha0 /f0 You should edit this script to reflect the devices that you use on your system. Files /etc/mtab -- Mount table /etc/mnttab -- Mount table /bin/mount -- Shell script that calls /etc/mount See Also commands, fsck, mkfs, mknod, umount Diagnostics Errors can occur if device or directory does not exist or if you do not have permission to access device. The message /etc/mtab older than /etc/boottime indicates that /etc/mtab has probably been invalidated by booting the system. Attempting to mount a block-special file that does not contain a COHERENT file system (e.g., a tape device) can have disastrous consequences. Caveat utilitor! To build a file system on a block-special device, use the command /etc/mkfs. For details, see its entry in the Lexicon.
