.ad
.RS 5n
Create a character-type special file.
.RE

.sp
.ne 2
.na
\fB\fBp\fR\fR
.ad

Create a FIFO (named pipe).
.RE

.SH OPERANDS
.LP
The following operands are supported:
.sp
.ne 2
.na
\fB\fImajor\fR\fR
.ad
.RS 9n
The \fImajor\fR device number.
.RE

.sp
.ne 2
.na
\fB\fIminor\fR\fR
.ad
.RS 9n
The \fIminor\fR 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.

\fB\fIname\fR\fR
.ad
.RS 9n
A special file to be created.

.SH USAGE
.LP
See \fBlargefile\fR(7) for the description of the behavior of \fBmknod\fR when
encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
.SH SEE ALSO
.LP
.BR ftp (1),
.BR mknod (2),
.BR symlink (2),
.BR attributes (7),
.BR largefile (7)
.SH NOTES
.LP
If \fBmknod\fR(2) is used to create a device, the major and minor device
numbers are always interpreted by the kernel running on that machine.
.sp
.LP
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 \fB/devices\fR
subtree) rather than using \fBmknod\fR.
