Name
       mkfifo - make fifo special files

Syntax
       mkfifo filename ...

Description
       The  command  creates the `fifo special files' named by its operand list.  The operands are taken sequentially, in the order specified, and
       each `fifo special file' is either completed or, in the case of an error or signal, not created at all. Unless interrupted, will attempt to
       create all files specified.  Error messages are written to standard error.

       Each  `fifo  file' is created with a mode of 666, read and write privileges for the user, group and other. The mode is modified by clearing
       those bits set in the process's file mode creation mask. See for more information.
