I have sort of had enough of copy and pasting commands I find on the internet without having a good understanding of how they actually work.
One thing you could do is start trying to understand those commands.
Read the man pages or the documentation to figure out what the commands are actually doing. Once you have the “what” , you can dig deeper to get to the “why” if it isn’t obvious by that point.
After enough of that, you’ll go to copy/paste and already understand what it’s doing without needing to look it up again.
Then from there, it’s a matter of building the instinct to be able to say “I need to do X, so I’ll use commands Y and Z.”
Back in the 90s, Windows NT had a POSIX compatibility layer that you could enable (it wasn’t enabled by default).
