In case you mostly copy+paste commands it would be safer to experiment on a VM than your everyday PC. There's no better way of learning than the hands-on approach, and a VM is a better test bed. You don't care if you FUBAR it (fuck up beyond any repair)
Just sayin' ...
Why not macOS VM since OP currently use that OS? I know both Linux and macOS could be categorized as UNIX family, but you might as well as get near 1:1 learning experience rather than wondering if you do same thing on both OS.
