MKNOD(8) Maintenance Commands and Procedures MKNOD(8)

mknod - make a special file

mknod name b major minor

mknod name c major minor

mknod name p

mknod makes a directory entry for a special file.

The following options are supported:


Create a block-type special file.


Create a character-type special file.


Create a FIFO (named pipe).

The following operands are supported:


The major device number.


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.


A special file to be created.

See largefile(7) for the description of the behavior of mknod when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

ftp(1), mknod(2), symlink(2), attributes(7), largefile(7)

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.
