4/1/2023 0 Comments Cat cpuinfo linux![]() ![]() There are obviously many more commands to get the CPU info, some of which are not available by default and need to be installed separately. The /proc/cpuinfo and sysfs stores info about your CPU architecture ike number of CPUs, threads, cores, sockets, NUMA nodes, information about CPU caches, CPU family, model, bogoMIPS, yte order and much more using the less command or more command as follows: less /proc/cpuinfo. In this article, we have seen how to check the CPU information in a Linux system. The file /proc/cpuinfo displays what type of processor your system is running including the number of CPUs present. ![]() There is less information in this output than ‘ lscpu‘ and the list of ‘ capabilities‘ is the same as the ‘ flags‘ listed in the output of lscpu. Note that even though we are just reading the information, this command is recommended to be run as super-user, i.e. We can use this command with the argument '-c CPU' to get a short output containing information about the CPU. The Linux CLI can provide you with detailed CPU information, such as the number of CPU cores, CPU architecture and CPU usage. The lshw stands for ‘ list hardware‘ and it’s a command to get information about all the hardware used by the Linux system. You can also save this output to a file by simply redirecting the output. For example, you can output the data in ‘JSON’ format using the option '-J'. This command has some useful options as well. To display complete CPU information, including per CPU clock-speed and CPU max speed (if available), use the -C flag as follows: inxi -C Print Linux System Information CPU: Dual core Intel Core i5-4210U (-HT-MCP-) cache: 3072 KB clock speeds: max: 2700 MHz 1: 1958 MHz 2: 1993 MHz 3: 1775 MHz 4: 1714 MHz 6. Command lscpuįirst, let us check out the simple command ‘lscpu’ which prints the information in a neat and more readable format. ![]() Apart from reading this file, there are few inbuilt commands which you can run to get the CPU information. This will output the contents on the command line, and you can press ‘Enter’ to scroll down. You can also view the contents of this file directly on the command line by running: $ less /proc/cpuinfo $ vim /proc/cpuinfoĪs you can see in the screenshot above, all the information like the model name, speed, cache size, is present in the file. Open the file /proc/cpuinfo using a text editor of your choice. In Linux, CPU information is stored in a system file, which can be either read using a text editor, or it can be read and used in an administrative shell script. The CPU Information in any machine includes information about the processor, the vendor details, model name, architecture, speed of processing, etc. ![]()
