MKNOD(1)

NAME
mknod - make block or character special files

SYNOPSIS
mknod [OPTION]... NAME TYPE [MAJOR MINOR]

DESCRIPTION

Create the special file NAME of the given TYPE.

Mandatory arguments to long options are mandatory for short options too.

-m, --mode=MODE
    set file permission bits to MODE, not a=rw - umask

-Z, --context=CTX
    set the SELinux security context of NAME to CTX

    When COREUTILS_CHILD_DEFAULT_ACLS environment variable is set, -m/--mode option respects default umask and ACLs, as it does in Red Hat Enterprise Linux 7 by default

--help
    display this help and exit

--version
    output version information and exit

Both MAJOR and MINOR must be specified when TYPE is b, c, or u, and they must be omitted when TYPE is p. If MAJOR or MINOR begins with 0x or 0X, it is interpreted as hexadecimal; otherwise, if it begins with 0, as octal; otherwise, as decimal. TYPE may be:

b   create a block (buffered) special file

c, u
    create a character (unbuffered) special file

p   create a FIFO

NOTE: your shell may have its own version of mknod, which usually supersedes the version described here. Please refer to your shell's documentation for details about the options it supports.
