:term

What’s an operating system without a terminal? The moduels in this category bring varying degrees of terminal emulation into Emacs.

If you can’t decide which to choose, I recommend vterm or eshell. :term vterm offers that best terminal emulation available but requires a few extra steps to get going. :term eshell works everywhere that Emacs runs, even Windows, and provides a shell entirely implemented in Emacs Lisp.
