MKNOD(1L)

NAME
mknod - make special files

SYNOPSIS
mknod [-m mode] [--mode=mode] path {bcu} major minor
mknod [-m mode] [--mode=mode] path p

DESCRIPTION
This manual page documents the GNU version of mknod. mknod creates a FIFO, character special file, or block special file with the given pathname. By default, the mode of created files is 0666 minus the bits set in the umask.

The argument after the path specifies the type of file to make:
p for a FIFO
b for a block (buffered) special file
c or u for a character (unbuffered) special file

When making a block or character special file, the major and minor device numbers must be given after the file type.

  OPTIONS

-m, --mode mode
    Set the mode of created files to mode, which is symbolic as in chmod and uses the default mode as the point of departure.

The long-named options can be introduced with `+' as well as `--', for compatibility with previous releases. Eventually support for `+' will be removed, because it is incompatible with the POSIX.2 standard.
