Learn any command fast — tldr examples plus fzf history search
tldr shows you the examples that matter; Ctrl-R with fzf finds the command you ran last month.
On Debian/Ubuntu, most of these tools are also one sudo apt install away.
brew install tldr # install, then: tldr --update
tldr tar # try: finally understand tar's flags
brew install fzf # install
vim $(fzf) # try: pick a file to open (or press Ctrl-R for history)
