lpsched(8)                          CLIX                          lpsched(8)



  NAME

    lpsched, lpshut, lpmove - Starts/stops LP scheduler and move requests

  SYNOPSIS

    /usr/lib/lpsched

    /usr/lib/lpshut

    /usr/lib/lpmove requests dest

    /usr/lib/lpmove dest1 dest2

  DESCRIPTION

    The lpsched command schedules requests taken by the lp(1) command for
    printing on line printers (LPs).

    Whereas, the lpshut command shuts down the line printer scheduler.  All
    printers that are printing at the time the lpshut command is invoked will
    stop printing.  Requests that were printing at the time a printer was
    shutdown will be reprinted in their entirety after the lpsched command is
    started again.

    The lpmove command moves requests that were queued by lp between
    destinations.  This command may be used only when the lpsched command is
    not running.

    The first form of the command moves the named requests to the line printer
    destination, dest.  The requests are request ids as returned by the lp
    command.  The second form moves all requests for destination dest1 to
    destination dest2.  As a side effect, the lp command will reject requests
    for dest1.

    Note that lpmove never checks the acceptance status (see accept) for the
    new destination when moving requests.

  EXAMPLES

    1.  To start the line printer scheduler:

        lpsched


    2.  To stop the line printer scheduler:

        lpshut


    3.  To move the print request req1 to the printer ilp811:

        lpmove req1 ilp811


    4.  Will move all requests scheduled for printer ilp811 to the printer
        epson80, and also stop scheduling requests for ilp811.

        lpmove ilp811 epson80


  FILES

    /usr/spool/lp/*

  DIAGNOSTICS

    scheduler not running
           An attempt was made to run lpshut when the LP scheduler was already
           stopped.

    lpsched: Can't open file
           One of the files needed to start the LP scheduler is missing.

    lpsched: can't set user id to LP Administrator's user id
           The user is not an LP administrator, or is not a superuser.

    lpmove: scheduler is still running - can't proceed
           The lpmove command was executed while the scheduler was still
           running.  Use lpshut first.

    lpmove: destination name nonexistent
           The destinations to move requests to does not exist.

    lpmove: destinations are identical
           An attempt was made to move all of the requests in a destination to
           the same destination.

    lpmove: name is not a request id
           An attempt was made to move a nonexistent request.

  EXIT VALUES

    The lpsched command will exit with a nonzero value when an error occurs.
