How to change the icon of your application from the terminal on Linux

Previously, we showed you how to easily change the application icons in Gnome 3. However, some users still prefer to use their terminal for this. It’s doable, but, as expected, the process is a little more complicated than a few mouse clicks. Let’s see how to change the icon of your application directly from your terminal.

Find your application’s desktop settings

Each application that appears on our desktop has a .desktop configuration file. This comes in the form of a text file, filled with values ‚Äč‚Äčthat define how it should act, operate, and look on the desktop. Among these, you can find a value for its icon.

Launch your preferred terminal and access the folder where you will find these settings files for all your applications, with:
