Command to find information about CPUs on a UNIX machine

Question

Do you know if there is a UNIX command that will tell me what the CPU configuration for my Sun OS UNIX machine is? I am also trying to determine the memory configuration. Is there a UNIX command that will tell me that?

Answer 1

There is no standard Unix command, AFAIK. I haven't used Sun OS, but on Linux, you can use this:

cat /proc/cpuinfo 

Sorry that it is Linux, not Sun OS. There is probably something similar though for Sun OS.

Answer 2

The nproc command shows the number of processing units available:
$ nproc

Sample outputs: 4

lscpu gathers CPU architecture information form /proc/cpuinfon in human-read-able format:
$ lscpu

Sample outputs:
