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 requested  by  options  is  shown  only  for  the
       specified device, otherwise all present devices are displayed.

       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.

       -m module_name
              Show information for a specific module.
