DESCRIPTION
mknod makes a directory entry for a special file.
OPTIONS

b
Create a block-type special file.
c
Create a character-type special file.
p
Create a FIFO (named pipe).
OPERANDS
The following operands are supported:
major
The major device number.
minor
The minor device number; can be either decimal or octal. The assignment of major device numbers is specific
to each system. You must be the super-user to use this form of the command.

USAGE
See largefile(5) for the description of the behavior
of mknod when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
ATTRIBUTES
See attributes(5) for descriptions of the following
attributes:
If mknod(2) is used to create a device, the major and minor
device numbers are always interpreted by the kernel running on that machine.
With the advent of physical device naming, it would be preferable to create a symbolic link to the physical name of the device (in the /devices subtree) rather than using mknod.
