NAME
     hinv - hardware inventory command

SYNOPSIS
     hinv [-v] [-s] [-m] [-c class] [-t type] [-d dev] [-u unit]

DESCRIPTION
     hinv displays the contents of the system hardware inventory table.  This
     table is created each time the system is booted and contains entries
     describing various pieces of hardware in the system.  The items in the
     table include main memory size, cache sizes, floating point unit, and
     disk drives.  Without arguments, the hinv command displays a one line
     description of each entry in the table.

     In addition, on some systems hinv can display manufacturing information
     such as board name, part number and barcode number.

     The hinv options are:

     -v         Gives a more verbose description of some items in the table.

     -c class   Displays items from class.  classes are processor, disk,
                memory, serial, parallel, tape, graphics, network, scsi,
                audio, iobd, video, bus, misc, compression, vscsi, and
                display.

     -t type    Displays items from type.  types are cpu, fpu, dcache, icache,
                memory, qic, a2, dsp, and scsictlr.

     -s         When used with either the -c or -t options, -s suppresses
                output.

     -d dev     Restricts the output to a kind of device among those currently
                present in the system.  The devices that currently support
                this option are cdsio, aso, ec, et, ee, enp, fxp, ep, gsn, hy,
                ipg, xpi, fv, gtr, mtr, hippi, myri, and atm.

     -u unit    Requests information for a single device unit number for a
                kind of device specified with -d.

     -m         Displays physical manufacturing information: board name, part
                number and barcode number.  When the -v flag is used in
                combination with -m the physical location of each board as a
                path under /hw is also displayed, see hwgraph(4D) for an
                explanation of the path.

     The hinv command, when used with the -c or -t options, exits with a value
     of 1 if no item of the specified class or type is present in the hardware
     inventory table.  Otherwise, hinv exits with a value of 0.


NOTE
     For many devices, the device will not be displayed in the inventory if
     the corresponding driver is not configured into IRIX.

     If all cpus in a system have the same speed, revision, and cache size,
     hinv will show the processor information in a summarized format.
     Otherwise, hinv will show each processor individually.
