There is also a field inside the information of each processor field which says cou cores are 2. The command-line utility lscpu in Linux is used to get CPU information of the system. ![]() Now it says that there are 4 processors on the system. You can get Linux CPU information by running the following command: sudo lshw -c cpu You will get output in your terminal as: Using lshw command to get cpu information You can further filter using grep command, type: sudo lshw -c cpu grep width or sudo lshw -c cpu grep bits 4. If such flag represents a hardware feature, it also means that the hardware supports it. Getting CPU Usage Using top Generally, the top command is usually utilized to display active processes on a system and how much resources the processes are consuming. cpuinfo is a library to detect essential for performance optimization information about host CPU. You can easily read its content and display it. If a given flag is present, it means that the kernel supports it and is currently making it available. The /proc/cpuinfo is a read-only file that contains information about the central processing units on a machine.
