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.
