     - build special file


    name [b | c ] major minor [owner : group ]  


    Bf -symbolic The utility is deprecated on modern Fx systems. Ef

    The utility creates device special files. To make nodes manually, the four required arguments are:

    Device name, for example ``sd'' for a SCSI disk on an HP300 or a ``pty'' for pseudo-terminals.
    b | c
    Type of device. If the device is a block type device such as a tape or disk drive which needs both cooked and raw special files, the type is b All other devices are character type devices, such as terminal and pseudo devices, and are type c
    The major device number is an integer number which tells the kernel which device driver entry point to use. To learn what major device number to use for a particular device, check /usr/src/sys/conf/majors
    The minor device number tells the kernel which subunit the node corresponds to on the device; for example, a subunit may be a file system partition or a tty line.
    owner : group
    The owner group operand pair is optional, however, if one is specified, they both must be specified. The owner may be either a numeric user ID or a user name. If a user name is also a numeric user ID, the operand is used as a user name. The group may be either a numeric group ID or a group name. Similar to the user name, if a group name is also a numeric group ID, the operand is used as a group name.

    Major and minor device numbers can be given in any format acceptable to strtoul(3), so that a leading `0x' indicates a hexadecimal number, and a leading `0' will cause the number to be interpreted as octal.

    The utility can be used to recreate deleted device nodes under a devfs(5) mount point by invoking it using dummy arguments. Example:

    "mknod cd0 c 0 0"

    where ``cd0 '' is the name of the deleted device node.  


    The chown(8)Ns- like functionality is specific to Fx .

    As of Fx 4.0 , block devices were deprecated in favour of character devices. As of Fx 5.0 , device nodes are managed by the device file system devfs(5), making the utility superfluous. As of Fx 6.0 device nodes may be created in regular file systems but such nodes cannot be used to access devices.

    A utility appeared in AT&T System v6 .
