NAME

       systool - view system device information by bus, class, and topology



SYNOPSIS

       systool [options [device]]



DESCRIPTION

       Calling  systool  without  parameters  will  present  all available bus
       types, device classes, and root devices.

       When device is supplied, the information reqested by options  is  shown
       only  for  the specified device, otherwise all present devices are dis-
       played.

       systool uses APIs provided by libsysfs to gather information.   systool
       runs only on Linux systems running kernels 2.5 or later, with the sysfs
       filesystem mounted.

       -b bus Show information for a specific bus

       -c class
              Show information for a specific class

       -d     Show only devices

       -h     Show usage

       -p     Show absolute sysfs path to the resource

       -r root_device
              Show a specific root device tree

       -v     Show all attributes with values

       -A attribute
