       NAME
             autopush - configure lists of automatically pushed STREAMS
             modules

       SYNOPSIS
             autopush -f file
             autopush -r -M major -m minor
             autopush -g -M major -m minor

       DESCRIPTION
             This command allows one to configure the list of modules to be
             automatically pushed onto the stream when a device is opened.
             It can also be used to remove a previous setting or get
             information on a setting.

             The following options apply to autopush:

             -f    This option sets up the autopush configuration for each
                   driver according to the information stored in the
                   specified file.  An autopush file consists of lines of
                   at least four fields each where the fields are separated
                   by a space as shown below:
                         maj_  min_  last_min_  mod1 mod2 ... modn

                   The first three fields are integers that specify the
                   major device number, minor device number, and last minor
                   device number.  The fields following represent the names
                   of modules.  If min_ is -1, then all minor devices of a
                   major driver specified by maj_ are configured and the
                   value for last_min_ is ignored.  If last_min_ is 0, then
                   only a single minor device is configured.  To configure
                   a range of minor devices for a particular major, min_
                   must be less than last_min_.

                   The last fields of a line in the autopush file represent
                   the list of module names where each is separated by a
                   space.  The maximum number of modules that can be
                   automatically pushed on a stream is defined to be eight.
                   The modules are pushed in the order they are specified.
                   Comment lines start with a # sign.

             -r    This option removes the previous configuration setting
                   of the particular major and minor device number
                   specified with the -M and -m options respectively.  If
                   the values of major and minor correspond to a setting of
                   a range of minor devices, where minor matches the first

                  minor device number in the range, the configuration
                  would be removed for the entire range.

            -g    This option gets the current configuration setting of a
                  particular major and minor device number specified with
                  the -M and -m options respectively.  It will also return
                  the starting minor device number if the request
                  corresponds to a setting of a range (as described with
                  the -f option).
