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:
