I’m using Linux (Ubuntu Mate / Ubuntu Studio) a little more these days, but I still have much more to learn.
I have found this bloke’s Youtube channel ‘Processors and Things’ beneficial to my Linux education, especially when it comes to ‘tar.gz’ files. He has a lot of other videos on his channel to help the Linux newcomer.
Google and stack overflow is more useful than this dude.
Also if you’re new to linux I really recommend elementaryos.
It’s built on ubuntu, very user friendly, and it look great.
I’ve been smitten with the Ubuntu platform (originally started with Linux Mint), lately I’ve been utilising Ubuntu Studio which I quite enjoy.
