Syntaxmkfifo filename ...
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 privi‐
leges 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
