.SH DESCRIPTION
.I Mknod
makes a special file.
The first argument is the
.I name
of the entry.
The second is
.B b
to make a file for a block device,
.B c
to make a character device.
The last two arguments are
numbers specifying the
.I major
device type
and the
.I minor
device (e.g. unit, drive, or line number).
.PP
Minor devices are specific to each device driver;
see the writeups in Section 4.
The assignment of major device numbers
varies with the implementation.
Here are some conventional ones
in the system used on VAXes:
