In this guide, we have shown you how to find information about your system CPU. Unlike the content of the /proc/cpuinfo file, the output of the lscpu doesn’t show a list of all logical CPUs.

The output will look something like below, including information about the number of CPUs, architecture, vendor, family, model, speed, caches, flags, etc. lscpu is a part of the util-linux package which is installed on all Linux distributions. Lscpu is a command-line utility that displays information about the CPU architecture. Another way to find the number of CPUs is by using the nproc command: nproc 8

Knowing the number of CPUs can be handy when you need to compile software from the source, and you want to know how many parallel processes can be concurrently executed. To print the number of CPUs: grep -c 'model name' /proc/cpuinfo 8 For example, to display only the processor name you would use: grep -m 1 'model name' /proc/cpuinfo model name : Intel(R) Core(TM) i5-8250U CPU 1.60GHz If you want to filter the output you can use the grep command Once you know the exact type of CPU you are having, you can check the product documentation about your processor’s specifications.

model name - The full name of the processor, including the processor brand.

processor - A unique identifying number of each processor, starting from 0.

The command will print each logical CPU with an identifying number. To display the contents of /proc/cpuinfo: less /proc/cpuinfo It will work no matter what Linux distribution you are using. Identifying the type of processor using the proc/cpuinfo file does not require installing any additional programs. The simplest way to determine what type of CPU you have is by displaying the contents of the /proc/cpuinfo virtual file. Whatever the reason, on Linux, it’s quite easy to determine the processor type and speed from the command line. Have you ever wondered what type of CPU you have in your system and what is the CPU speed? There are various reasons why you might need to know what CPU you have inside your machine.

It performs all types of data processing operations, and it often referred to as the computer’s brain. The CPU (central processing unit), often called simply processor, is one of the essential components of your computer.
