34*0Sstevel@tonic-gate  * autopush(1) is the command interface to the STREAMS autopush
35*0Sstevel@tonic-gate  * mechanism.  The autopush command can be used to configure autopush
36*0Sstevel@tonic-gate  * information about a STREAMS driver, remove autopush information,
37*0Sstevel@tonic-gate  * and report on current configuration information.  Its use is as
38*0Sstevel@tonic-gate  * follows:
39*0Sstevel@tonic-gate  *
40*0Sstevel@tonic-gate  *	autopush -f file
41*0Sstevel@tonic-gate  *	autopush -r -M major -m minor
42*0Sstevel@tonic-gate  *	autopush -g -M major -m minor
43*0Sstevel@tonic-gate  *
44*0Sstevel@tonic-gate  * The -f option allows autopush information to be set from a file.  The
45*0Sstevel@tonic-gate  * format of the file is as follows:
46*0Sstevel@tonic-gate  *
47*0Sstevel@tonic-gate  * # Comment lines begin with a # in column one.
48*0Sstevel@tonic-gate  * # The fields are separated by white space and are:
49*0Sstevel@tonic-gate  * # major	minor	lastminor	module1 module2 ... module8
50*0Sstevel@tonic-gate  *
51*0Sstevel@tonic-gate  * "lastminor" is used to configure ranges of minor devices, from "minor"
52*0Sstevel@tonic-gate  * to "lastminor" inclusive.  It should be set to zero when not in use.
53*0Sstevel@tonic-gate  * The -r option allows autopush information to be removed for the given
54*0Sstevel@tonic-gate  * major/minor pair.  The -g option allows the configuration information
55*0Sstevel@tonic-gate  * to be printed.  The format of printing is the same as for the file.
