The following are some demonstrations of the prtdevs program, which
prints out device instance names. This began as a solution for neatly
listing all network interfaces, whether they are plumbed or not.

This example is on an UltraSPARC 10,

   $ uname -i
   SUNW,Ultra-5_10
   $
   $ prtdevs
   cpu: 0
   mem: 384 Mb
   disk: dad0 dad1 fd0 sd16 sd31
   network: hme0

Another example is,

   $ uname -i
   SUNW,Ultra-60
   $
   $ prtdevs
   cpu: 0 2
   mem: 1024 Mb
   disk: fd0 lofi1 md0 sd0 sd1 sd6
   network: hme0 qfe0 qfe1 qfe2 qfe3 qfe4 qfe5 qfe6 qfe7
