mkfifo(1)						      General Commands Manual							 mkfifo(1)

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.

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 rela-
		tive 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.
