 1.6 Running the 'time' Command
 ==============================
 
 The format of the 'time' command is:
 
      time [option...] COMMAND [ARG...]
 
    'time' runs the program COMMAND, with any given arguments ARG....
 When COMMAND finishes, 'time' displays information about resources used
 by COMMAND (on the standard error output, by default).  If COMMAND exits
 with non-zero status or is terminated by a signal, 'time' displays a
 warning message and the exit status or signal number.
 
    Options to 'time' must appear on the command line before COMMAND.
 Anything on the command line after COMMAND is passed as arguments to
 COMMAND.
 
 '-o FILE'
 '--output=FILE'
      Write the resource use statistics to FILE.
 
 '-a'
 '--append'
      _Append_ the resource use information to the output file instead of
      overwriting it.
 
 '-f FORMAT'
 '--format=FORMAT'
      Use FORMAT as the format string.
 
 '--help'
      Print a summary of the command line options to 'time' and exit.

      Use the POSIX format.
