Thank you so much, comrades! I am feeling pretty comfortable with linux mint, and now would like some suggestions for some absolutely necessary FOSS or free license software for the OS. So far I have the standard, Firefox, ThunderBird, LibreOffice, yada yada. Thank you again to everyone on the linux comm! 
Logseq is a pretty nice FOSS alternative to Obsidian I came across recently. Tmux is absolutely necessary for any terminal work. Wezterm is my favorite terminal emulator because you can easily disable all of the shortcuts except very few you want (tmux handles most of terminal stuff for me). Some new alternatives to old command line utilities:
fun fact
I also recently learned that it’s safer, because you can have a file that has some bad command, then the backspace character several times, and cat doesn’t display the characters “deleted” by the backspaces (but it still executes). Bat doesn’t do that.
You know any better cd?
I use zoxide plus fzf which ends looking like this.
My default go-to for a better cd was teleport when I still was on bash. The tp command can be aliased to cd. I don’t think it will run on other shells though.
What? It’s literary in my comment.
Oh, Sorry I didn’t notice also thanks to tell us about bat. It’s much better than cat.
Personally, instead of Tmux, I’d recommend trying Zellij. I started with Zellij right out of the gate, but a friend of mine who dislikes Tmux a lot quite enjoyed Zellij, so I assume it’s somewhat better.
I know about Zellij, but in its current state, I think it doesn’t make sense for me to switch. I really lobe my Tmux setup, and I don’t think I would be able to replicate it on Zellij, mainly because of Tmux plugins I use. I also don’t think that Zellij currently has any advantages over Tmux except for better default config and user friendliness that I don’t need. I’m looking forward to the Zellij ecosystem getting better tho. Some day, I will probably make the switch. The WASM tabs feature looks extremely promising!
