Hi,

Is there a command that I can use to see the number of CPU's in the system?

Thanks

You can see the cpu info in /proc/cpuinfo

less /proc/cpuinfo

Note: Processors with 2 cores(Or more) can be shown twice (Or more)

On Solaris you can do:

uname -X

Or you can do the following:

psrinfo -p

Shows the number of physical processors

psrinfo -pv

Shows the number of virtual processors (Number of cores x Number of threads)

You can also use

x86info a

But you might need to install it first
on debian/ubuntu

apt-get install x86info

How can I see the number of CPU's in Linux
