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


systool [options [device]]


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 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.
