How to zoom in and zoom out terminal console in linux

Linux is a Debian-based Operating system used by many professionals and other people for various purposes. Mainly Linux is used for Penetration testing and Vulnerability assessment. Windows systems often interact with GUI (graphical user interface) but in Linux, we use a terminal console more to interact with the system and to do things normally. In this article, we will see how we can use the Zoom in and Zoom out features in this terminal console of Linux. We will see what the keyboard shortcuts are to zoom in and out and also see how to do so with the terminal itself.

How to Zoom in and Zoom out in the Linux Terminal?

For doing zoom in and zoom out in the terminal we have two different methods. We have listed this method below:

• Method 1: Using Shortcut Keys
• Method 2: Using the Inbuilt Functionality of the Terminal

Let's explore both the methods with step-by-step execution:

Method 1: Using Shortcut Keys

Step 1: To use Zoom in and Zoom out in the terminal you can use keyboard shortcuts, to do so first open your terminal by the taskbar, or you can search for it in applications. Press the below Keyboard Shortcut to open the terminal in Linux.

Method 2: Using the Inbuilt Functionality of the Terminal

Step 1: To use inbuilt zoom-in and zoom-out functionality, first navigate to the terminal and select the Edit Tab from the menu bar. You can refer to the below screenshot for navigation.

Step 2: After clicking on the Edit Tab, multiple sub-options will be displayed. From these sub-options, we need to select Zoom in option to perform zooming into the terminal. After clicking on the option, you can see in the below video file, that our zooming-in is performed successfully.

Step 3: From the drop-down apperated after clicking on the Edit Tab option, we can select the option of Zoom out to perform zooming out in the terminal. We have done the zoom-out process in the below demonstration.

How to Zoom in and Zoom out in the Ubuntu Terminal?

To use Zoom in and Zoom out functionality in Ubuntu is similar to what we have done in Linux above, the main difference is the environment and the terminal sometimes different distribution uses different terminal consoles. So let's see how to use Zoom functionality in Ubuntu.

There are 2 methods to use it:

• Method 1: By keyboard shortcuts
• Method 2: By inbuilt functionality within the terminal

Method 1: By using Keyboard Shortcut in the Ubuntu terminal

Step 1: Open your Ubuntu instance and open the terminal on it. let's just write a simple text like Hello from GeeksforGeeks !, and we will see how to zoom in and zoom out.

Step 2: Press CTRL + '=' to zoom in on the text and increase its size on the terminal, as you can see in the below output.

CTRL + '='

Step 3: Press CTRL + '_' to zoom out the text and decrease its size on the terminal, as shown in below output example below.

CTRL + '_'   

in the above command _ key is the key that is also the - key, In Ubuntu by default shortcuts for zoom in and zoom out are Ctrl++ where + is = key and Ctrl-- where - is _ key.

Method 2: By using the Inbuilt functionality of the Ubuntu terminal

Step 1: Keep your terminal open, you can clear the screen with a clear command. let's type the same text we have written above Hello from GeeksforGeeks!

Step 2: Now you can see a 3-line bar box (More Options) in the top right corner of the terminal, You can click it to see the options it has.

Step 3: We can see that the menu has zoom-in and zoom-out functionality, you can simply use it by clicking on it as per your requirement for text size. below are the outputs for both of the functions.

Select the Zoom out icon from the options.

Question 2: What if my keyboard shortcuts for zooming in and out are not working in the terminal?

If keyboard shortcuts are not working for your terminal emulator, then it might be the case that your terminal is not configured to allow zoom-in, You can change this to allow your terminal to zoom in by referring to the documentation of your terminal.

Question 3: Can I zoom in and out of the terminal console on a remote server?

Yes you can zoom in and out on a remote server just make sure that your terminal supports the remote connections. once you are connected you can use your normal keyboard shortcuts like always.

Question 4: What is the difference between zooming in and out of the terminal console and resizing the terminal window?

Zooming in and out of the terminal console changes the size of the text while resizing the terminal window changes the size of the terminal window itself. when you change the size of the terminal window all of the aspects of the terminal will increase in size like the title, options bar, logo, and all. but in Zoom in case it only affects the text on the terminal.

Question 5: How do I change the default zoom level for the terminal console?

The default zoom level for the terminal console is 100%. You can change the default zoom level by editing the terminal emulator's configuration file. the location of the configuration file depends upon your terminal.

Conclusion
