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

### -Z

       **--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;  other‐
       wise, 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 de‐
       scribed here.  Please refer to your shell's documentation for details about  the  options  it
       supports.
