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.
