     P(1)                                                         P(1)

          p - paginate

          p [ -number ] [ file ... ]

          P copies its standard input, or the named files if given, to
          its standard output, stopping at the end of every 22nd line,
          and between files, to wait for a newline from the user.  The
          page size may be set by saying (for example)

               `p -60'

          While waiting for a newline, p interprets the commands:

          !    Pass the rest of the line to the shell as a command.

          q    Quit.
