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 for sure, 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. THANK YOU so much for this! I am new to Linux, and I am trying to teach myself more about using the command line. I can tell it is a faster, more powerful alternative to “point and click” with the mouse, for many tasks.

    Having all these commands in a well-organized fashion is a big help to me. Thank you. ( :

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