How to check cpu and memory in linux command

Let’s take a look at how we can view CPU info on Ubuntu Linux.

Ubuntu memory info

There are a couple ways, one is to look at the /proc/cpuinfo.

Go to Ubuntu terminal and enter the following command:

The Ubuntu kernel keeps information about your CPU in the /proc/cpuinfo file.

When queried, it provides lots of information about the processor on your Ubuntu Computer.

From the preceding output, we can see /proc/cpuinfo file contains lots of information such as vendor_id, model name, cache size, the CPU rate in MHZ, and so on.

Viewing CPU info with lscpu command

The lscpu command on Ubuntu displays CPU information in a user-friendly way.

Actually, it collects information from the /proc/cpuinfo file and presents it in a way that the user can understand easily.

Looking at the lscpu output, we can say that my Ubuntu machine has AMD dual-core processor.
