NAME
       mkfifo - make FIFO special file

SYNOPSIS
       /usr/bin/mkfifo [-m mode] path...

DESCRIPTION
       The mkfifo utility creates the FIFO special files named by its argument list. The arguments are taken sequentially, in the order specified;
       and each FIFO special file is either created completely or, in the case of an error or signal, not created at all.

       If errors are encountered in creating one of the special files, mkfifo writes a diagnostic message to the standard error and continues with
       the remaining arguments, if any.

       The  mkfifo  utility calls the library routine mkfifo(3C), with the path argument is passed as the path argument from the command line, and
       mode is set to the equivalent of a=rw, modified by the current value of the file mode creation mask umask(1).

OPTIONS
       The following option is supported:

       -m mode	  Sets the file permission bits of the newly-created FIFO to the specified mode value. The mode option-argument will be  the  same
		  as  the  mode operand defined for the chmod(1) command. In <symbolicmode> strings, the op characters + and - will be interpreted
		  relative to an assumed initial mode of a=rw.

OPERANDS
       The following operand is supported:

       file    A path name of the FIFO special file to be created.

USAGE
       See largefile(5) for the description of the behavior of mkfifo when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

ENVIRONMENT VARIABLES
       See environ(5) for descriptions of the following environment variables that affect the execution of mkfifo: LANG, LC_ALL, LC_CTYPE, LC_MES-
       SAGES, and NLSPATH.

EXIT STATUS
       The following exit values are returned:

       0     All the specified FIFO special files were created successfully.

       >0    An error occurred.
