To see computer specifications using the command line interface, you must open the terminal console on your Linux by pressing the CTRL + ALT + DEL button, then type a specific command to see the hardware specifications you want to know.

1. Checking Processor Specifications

To find out the details of the processor installed on your computer, you can type the following command in the terminal console.

$ cat /proc/cpuinfo

With this command, information about the processor on your computer will be displayed in detail. But you can also check one item, for example, you want to know the type of processor, then you can type the following command.

$ cat /proc/cpuinfo | grep 'model name'


2. Checking Memory Specifications (RAM)

To check the amount of memory (RAM) installed on your computer, please type the following command.

$ cat /proc/meminfo

Or if you only want to check the total memory (RAM), please type this command.

$ cat /proc/meminfo | grep 'MemTotal'


3. Check the VGA Card Specifications

To find out the specifications or model of the graphics card on your computer, you can check it with the following command.

$ lspci | grep VGA

4. Check all hardware specifications

If you want to know the overall hardware specifications installed on your computer, you can use the lshw command, this command will output the information on all hardware specifications on your computer.

$ lshw -short

How to check computer specifications with GUI-based applications

In addition to checking computer specifications with the CLI, you can also check using a GUI-based application i.e. hardinfo, with this application allowing you to easily check the specifications installed on your computer.

But before you have to install it first, type the following command in the terminal console to install the application.

$ sudo apt-get install hardinfo

If it's already installed, you can open the application by typing the command.

$ hardinfo

Then the System Information application window will open as shown below.
