How to Find Three Key Aspects of a CPU - Getting CPU Details in Linux

As a Linux user, I can understand your obsession with CPU.

Sometimes you want to know every detail of your notebook. How many cores are there? Is it a virtual processor or a chemical processor? Who is the manufacturer? And more.

So, how to get CPU details in Linux?

In this tutorial, I will guide you through three key aspects of how to find a CPU:

1. Obtain detailed CPU information

2. What is the current CPU usage of each core

3. Understand the CPU temperature

Let’s start with the first one.

#Find CPU detailed information in Linux

The easiest way to get detailed CPU information in Linux is to use the lscpu command. The best part is that it doesn't require any installation.

To know every detail of the CPU, just execute the lscpu command as shown below:

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">lscpu<br></code>

Let’s break down the output one by one.

NUMAnode(s): A NUMA node is a group of CPU cores and memory strips that are chemically close together and share a local memory controller.

NUMAnode0CPU(s): It means that I have a NUMA node named node0, but all the cores are located in the same NUMA code.

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">NUMA node0 CPU(s):     0-7,16-23<br>NUMA node1 CPU(s):     8-15,24-31<br></code>

What else do you need?

#Find the current CPU usage of each core

You can use the top command to detect the CPU utilization rate. However, the htop command is a better tool than top. It displays the CPU usage of each core in a better and friendly interface.

And it is not pre-installed in most Linux distributions.

Delete the directory for this LINUX, here I will show you how to install and use htop to monitor the current CPU usage.

For Ubuntu users:

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">sudo apt install htop<br></code>

For Fedora users:

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">sudo dnf install htop<br></code>

对于ArchLinux:

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">sudo pacman -S htop<br></code>

安装完成后linux 获取版本信息，您可以使用以下命令启动htop:

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">htop<br></code>

如您所见，它显示了怎样借助每位核心，以及系统中运行的显存消耗和任务总量。

#在Linux中查找CPU气温

要找到CPU体温linux 获取版本信息，你所须要的只是一个名为lm-sensors的实用程序，下边是怎样在各类Linux发行版上安装的方式:

对于Ubuntu/Debian用户:

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">sudo apt install lm-sensors<br></code>

对于Fedora:

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">sudo dnf install lm_sensors<br></code>

ForArch:

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">sudo pacman -S lm_sensors<br></code>

安装完成后，执行以下命令，它将显示CPU的气温：

<span></span><code style="padding: 16px;color: #abb2bf;padding-top: 15px;background: #282c34;border-radius: 5px;, Consolas, Monaco, Menlo, monospace;border-top-left-radius: 0px;border-top-right-radius: 0px;border-bottom-right-radius: 0px;border-bottom-left-radius: 0px;font-size: 12px">sensors<br></code>

#结束

在本教程中，我介绍了怎样使用lscpu命令获取CPU详尽信息，还提及了怎样检测CPU使用情况和湿度。

在Linux中有更多的工具可以获取系统硬件细节。我用的是最常见的。

我希望你会发觉这个快速提示有帮助。假如有任何问题请告诉我。
