There must be foss alternatives to every proprietary software. Big thanks to GNU and Linus Torvalds that joined their forces and created GNU/Linux!

2 things got me comfortable on command line: 1) A great cheat sheet (one from Ubuntu: https://ubuntu.com/download/server/thank-you); 2) Practice all the commands from the cheat list regularly. Last page is something for Pro version, but first 2 pages are great for a begginer. There is a typo at a command (or it was in a past cheat sheet): “Sudo change <username>” instead of “sudo chage <username>”. It helped me most to get comfortable with terminal. Enjoy!

Great magazine, thanks for posting!
