+# mknod
+
+```
+mknod [OPTION]... NAME TYPE [MAJOR MINOR]
+```
+
+Create the special file NAME of the given TYPE.
+
+## After Help
+
+Mandatory arguments to long options are mandatory for short options too.
+-m, --mode=MODE    set file permission bits to MODE, not a=rw - umask
+--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.
