317c478bd9Sstevel@tonic-gate * autopush(1) is the command interface to the STREAMS autopush
327c478bd9Sstevel@tonic-gate * mechanism. The autopush command can be used to configure autopush
337c478bd9Sstevel@tonic-gate * information about a STREAMS driver, remove autopush information,
347c478bd9Sstevel@tonic-gate * and report on current configuration information. Its use is as
357c478bd9Sstevel@tonic-gate * follows:
367c478bd9Sstevel@tonic-gate *
377c478bd9Sstevel@tonic-gate * autopush -f file
387c478bd9Sstevel@tonic-gate * autopush -r -M major -m minor
397c478bd9Sstevel@tonic-gate * autopush -g -M major -m minor
407c478bd9Sstevel@tonic-gate *
417c478bd9Sstevel@tonic-gate * The -f option allows autopush information to be set from a file. The
427c478bd9Sstevel@tonic-gate * format of the file is as follows:
437c478bd9Sstevel@tonic-gate *
447c478bd9Sstevel@tonic-gate * # Comment lines begin with a # in column one.
457c478bd9Sstevel@tonic-gate * # The fields are separated by white space and are:
467c478bd9Sstevel@tonic-gate * # major minor lastminor module1 module2 ... module8
477c478bd9Sstevel@tonic-gate *
487c478bd9Sstevel@tonic-gate * "lastminor" is used to configure ranges of minor devices, from "minor"
497c478bd9Sstevel@tonic-gate * to "lastminor" inclusive. It should be set to zero when not in use.
507c478bd9Sstevel@tonic-gate * The -r option allows autopush information to be removed for the given
517c478bd9Sstevel@tonic-gate * major/minor pair. The -g option allows the configuration information
527c478bd9Sstevel@tonic-gate * to be printed. The format of printing is the same as for the file.
