* CPU Info

cpuid

cat /proc/cpuinfo

cat /proc/cpuinfo | grep processor | wc -l

*The number of processors shown by /proc/cpuinfo might not be the actual number of cores on the processor.

For example a processor with 2 cores and hyperthreading would be reported as a processor with 4 cores.

cat /proc/cpuinfo | grep 'core id'

core id : 0

core id : 2

core id : 1

core id : 3

So there are 4 different core ids. This indicates that there are 4 actual cores.
