NAME

       lsdev - list device drivers in the system

SYNOPSIS

       driver | class] block_major] char_major] major] [major ...]

DESCRIPTION

       The  command lists, one pair per line, the major device numbers and driver names of device drivers configured into the system and available
       for invocation via special files.  A in either the block or character column means that a major number does not exist for that type.

       If no arguments are specified, lists all drivers configured into the system.

       If the option is specified, will not print a heading.  This option may be useful when the output of will be used by another program.

       The and options are used to select specific device drivers for output.  If more than one option is specified, all drivers  that	match  the
       criteria  specified  by	those options will be listed.  These search options are divided into two types: name search keys (the and options)
       and major number search keys (the and options).	If both types of options are present, only entries that match both types are printed.  The
       same  type of option may appear more than once on the command line with each occurrence providing an ORing effect of that search type.  The
       and options may not be specified at the same time.

       The ability to process major arguments is provided for compatibility and functions like the option.

   Options
	      List device drivers that match
				  class.

	      List device drivers with the name
				  driver.

	      List device drivers with a block major number of
				  block_major.

	      List device drivers with a character major number of
				  char_major.

	      List device drivers with either a character
				  major number or block major equal to major.

DIAGNOSTICS

       The    and options may not be specified at the same time.

       A major number is malformed or out of range.

EXAMPLES

       To output entries for all drivers in the class:

       To output entries that are in the class that have either a block or character major number of

       To get the character major number of into a shell environment variable:

WARNINGS

       Some device drivers available from the system may be intended for use by other drivers.	Attempting to use them	directly  from	a  special
       file may produce unexpected results.

       A  driver  may be listed even when the hardware requiring the driver is not present.  Attempts to access a driver without the corresponding
       hardware will fail.

       only lists drivers that are configured into the currently executing kernel.  For a complete list of  available  drivers,  please  run  (see
       sam(1M).

DEPENDENCIES

       Since relies on the device driver information provided in a routine, may not list drivers installed by other means.
