Ask HN: What is a piece of advice that you would give to a new Linux user?

Assuming a casual user. Follow a quick tutorial on how to use and navigate the command line. As for everything else, just learn it if and when you need it.

I'd recommend doing your experiments on a virtual machine like Hyper-V so you can spin up different version and kill or revert them if you have problems. On Windows, you can run Ubuntu (WSL) like any other app.

learn about the posix standard , if you understand the past it becomes much more clear why things are the way they are.
