I see I have a processor 0 and processor 1. Model name : Intel(R) Core(TM)2 Quad CPU Q6600 2.When running cat /proc/cpuinfo under Linux, a variety information is kicked-back. But it prints out this information for each virtual core. For example, if you have 8 core processor you will see a list of all cores starting from 0 to 7. The command will print each logical CPU with an identifying number. CPU: grep address size /proc/cpuinfo address sizes : 46 bits physical, 48 bits virtual address sizes : 46 bits. Lscup could be a simple ‘cat /proc/cpuinfo’ as there is no substitute ~]# cat /proc/cpuinfo Do you expect to have 8 physical cores (with hyperthreading they could be counted as 16 virtual cores) or do you expect to have 4 physical but 8 virtual cores cat /proc/cpuinfo should print out the number of physical cores. Open your terminal and use less or cat to display the contents of /proc/cpuinfo: less /proc/cpuinfo. Great but… there is a but… You didn’t said that “lscpu” and “nproc” are only available on Debian like Linux ! address sizes : 39 bits physical, 48 bits virtual power management: processor : 4 vendorid : GenuineIntel cpu family : 6 model : 60 model name : Intel (R) Core (TM) i7-4700HQ CPU 2.40GHz stepping : 3 microcode : 0x12 cpu MHz : 800. Here is a quick demo of lscpu and /proc/cpuinfo commands: 4416.00 clflush size : 64 cachealignment : 64 address sizes : 39 bits physical. $ grep -c processor /proc/cpuinfo Check out related media cmdecho ((cat /proc/cpuinfo grep cores grep -o 0-9.
