MKNOD(1) User Commands MKNOD(1)
mknod - make block or character special files
mknod [OPTION]... NAME TYPE [MAJOR MINOR]
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 set the SELinux security context to default type
--context[=CTX]
like -Z, or if CTX is specified then set the SELinux or
SMACK security context to CTX
--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
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.
