How To Find CPU Cores in Linux
Linux systems provide several ways to get a detailed picture of a CPU with its cores. This article will cover four top most and easiest ways to get it.
1: Find CPU Cores in Linux Using lscpu Command
The lscpu command is one of the easiest commands in the Linux system to fetch complete details of CPU architecture.
What we need to do is just simply type “lscpu” in the terminal:
2: Find CPU Cores in Linux Through /proc/cpuinfo File
When we run “lscpu” command, it fetches information from sysfs and /proc/cpuinfo. So, it is good to get directly all details by running this command on terminal:
3: Find CPU Cores in Linux Using top/htop Command
The top command is used to report processor activities in Linux systems. It displays all the kernel tasks, running Linux processes yet all the system resources. The htop command is one of the iterations of the top command.
Type “top” in the command-line to get complete picture of system:
After running the above command, press 1:
You can also use the “htop” command but it is not pre-installed in Linux Mint 21 system. For this, first install it through the mentioned command:
Now, run the below-mentioned command to find CPU core in Linux system:
4: Find CPU Cores in Linux Using nproc Command
To display the available processing units in a Linux system, the “nproc” command is used. We can also check all the installed processors on the system using the “nproc all” command. Let’s check how we can find it, run in terminal:
Cores are processors that help any system to work on multiple tasks and enhance the performance. System processors can be dual-core, quad-core (4 cores), and even the latest generation can have 18 cores. We have checked how we can find the number of cores using lscpu, top/htop and nproc commands in the Linux system.
