MKFIFO(1)						    BSD General Commands Manual 						 MKFIFO(1)

NAME

     mkfifo -- make fifos

SYNOPSIS

     mkfifo [-m mode] fifo_name ...

DESCRIPTION

     mkfifo creates the fifos requested, in the order specified.  By default, the resulting fifos have mode 0666 (rw-rw-rw-), limited by the cur-
     rent umask(2).

     The options are as follows:

     -m      Set the file permission bits of newly-created fifos to mode, without respect to the current umask.

	     The mode is specified as in chmod(1).  In symbolic mode strings, the ``+'' and ``-'' operators are interpreted relative to an assumed
	     initial mode of ``a=rw''

     mkfifo requires write permission in the parent directory.

     mkfifo exits with 0 if successful, and with >0 if an error occurred.

LEGACY DESCRIPTION

     In legacy mode, the fifo's file permission bits are always limited by the current umask.

     For more information about legacy mode, see compat(5).

STANDARDS

     The mkfifo utility is expected to be IEEE Std 1003.2-1992 (``POSIX.2'') compliant.

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.
