What shell/terminal setup would you recommend to beginners today?

Ghostty with bash (have Claude setup oh my bash) and a custom atuin config so Ctrl-r is usable.

A terminal with copy on select. And use the default shell. Zsh on Mac bash on every Linux I’ve ever used (I can’t really tell the difference). Extend your history limit and close your windows now and then so they write to the history file. If you’re doing shell scripting follow the Google style guide.
