2 ways come to mind:
$ lshw -short
install it, run it from a shell (in java)
-----------------------------------------------------------------
you can also try this in b4j using java objects:
Dim properties As JavaObject ' java.util.Properties
jo.InitializeStatic("java.lang.System")
Dim out As JavaObject = jo.GetField("out")
properties = jo.RunMethod("getProperties",Null)
' show properties in log 2 ways:
Log(properties)
properties.RunMethod("list",Array(out))
no guarantee cpu vendor information is available/captured.
no guarantee your particular flavor or linux permits access from userland.
the b4j snippet works on windows. i'm too weak to drag out a linux box to try it there.
