List of Linux acronyms and their details

About a week ago, I discussed with my friend some Linux topics.

At the time, he told me that he didn’t find a proper resource to find information about Linux command acronyms.

I did a little research, but I didn’t find what I wanted about this topic.

So I decided to write an article about it.

It may help others who are looking for this information.

We have added a very small number of acronyms at this time.

But I can say with certainty, over the period of time, we will load a dozen of abbreviations.

So I urge you to stay on this page.

Also, if you would like to contribute to this article I would request you to update the information about acronyms in the comment section.

We are very happy to update this on your behalf.

  1. DE stands for Desktop Environment,
    and I remember GUI stands for Graphical User Interface and UI stands for User Interface.
