NAME
      mkfifo - make FIFO special file
 


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


DESCRIPTION
      The mkfifo command 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 command 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 crea-
      tion mask umask(1).
 


OPTIONS
      The following option is supported:
 
      -m mode
            Set 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).
