Carlos,
I really enjoyed the layout, as well as the great simplified definitions in your post. Linux is not something I have ever been to familiar with and am looking forward to seeing what everyone else knows. Being able to read about what you all know. Has been immensely helpful in my learning and understanding.
One question I do have. Is there a way you/anyone else here has to easier manage all the different OS’s and easier differentiate the subtle differences in their commands? This seems like a lot of different knowledge a lot like coding. If you don’t use it. Remembering it is very complicated.
