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.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+

NAME

       mkfifo - make FIFO (named pipe) special files

SYNOPSIS

       mode] filename ...

DESCRIPTION

       creates	the FIFO special files named by its operand list.  The operands are taken sequentially in the order specified and, if the user has
       write permission in the appropriate directory, the FIFO is created with permissions 0666 modified by the user's	file  mode  creation  mask
       (see umask(2)).

       The specific actions performed are equivalent to calling

       for each filename in the operand list (see mkfifo(3C)).

   Options
       recognizes the following command-line options:

	      After creating the
			     FIFO  special file, set the permission bits of the new file to the specified mode value.  The mode option argument is
			     a symbolic mode string as defined in chmod(1).

			     In the symbolic mode strings, the operators and will be interpreted relative to an initial mode of a=rw.

	      Create any missing intermediate path name components.

EXTERNAL INFLUENCES

       For information about the UNIX standard environment, see standards(5).

   Environment Variables
       determines the locale to use for the locale categories when both and the corresponding environment variable (beginning with do not  specify
       a locale.  If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used.

       determines  the locale to use to override any values for locale categories specified by the settings of or any environment variables begin-
       ning with

       determines the locale for the interpretation of sequences of bytes of text data as characters (e.g., single- versus multibyte characters in
       arguments).

       If  any	internationalization  variable	contains an invalid setting, behaves as if all internationalization variables are set to "C".  See
       environ(5).

   International Code Set Support
       Single-byte character code sets are supported.

RETURN VALUE

       returns zero if invoked with at least one operand and if all FIFO special files were created successfully.  Otherwise, it prints a diagnos-
       tic message and returns non-zero.

EXAMPLES

       The following command creates a FIFO special file named in the current directory:
