NAME

       autopush - manage system database of automatically pushed STREAMS modules

SYNOPSIS

       file

       major minor

       major minor

DESCRIPTION

       manages	the  system  database that is used for automatic configuration of STREAMS devices.  The command is used in three different ways as
       dictated by the and command-line options described below.

   Options
       recognizes the following command-line options and arguments:

	      Using the configuration information contained in
			     file, load the system database with the names of the STREAMS devices and a list of modules to use	for  each  device.
			     When a device is subsequently opened, the HP-UX STREAMS subsystem pushes the modules onto the stream for the device.

			     If appears as a file argument, uses the standard input.

			     file must contain one or more lines of at least four fields separated by a space as shown below:

			     major minor lastminor module1 module2 ... moduleN

			     The  first field major can be either an integer or a device name.	The device name is the name for the device used in
			     the master file.  The next two fields are integers.  If minor is set to -1, then all minor devices for the  specified
			     major  are configured and lastminor is ignored.  If lastminor is 0, then only a single minor device is configured. To
			     configure a range of minor devices for a major device, minor must be less then  lastminor.   The  remaining  field(s)
			     list  one	or  more  module  names.   Each module is pushed in the order specified. A maximum of eight modules can be
			     pushed.  Any text after a # character in file is treated as a comment for that line only.

			     This option is also used to restore device configuration information previously removed by However, when used in such
			     a manner, the entire database is restored, not just the information that was previously removed.

	      Display current configuration information from the system database for the
			     STREAMS  device  specified  by the major device number (or device name for the device from the master file) and minor
			     number.

			     If a range of minors has been previously configured then returns the configuration information for the first minor in
			     the range, in addition to other information.

	      Remove configuration information from the system database for the
			     STREAMS  device  specified  by  the major device number (or device name for the device from the master file and minor
			     number.  Removal is performed on the database only, not on the original configuration file.  Therefore, the  original
			     configuration  can  be restored by using the file option.	To permanently exclude a STREAMS device from the database,
			     its information must be removed from the configuration file.

			     If minor matches the first minor of a previously configured range then removes the configuration information for  the
			     entire configured range.

EXAMPLES

       If the file contains:

       Then will cause and to be pushed whenever major device is opened, and and to be pushed for the first six opens of device

       This next example lists information about the stream for major device and its minor device
