Is there an Emacs shell written in eshell?
Eshell is a shell written entirely in Emacs-Lisp, and it replicates most of the features and commands from GNU CoreUtils and the Bourne-like shells. So by re-writing common commands like ls and cp in Emacs-Lisp, Eshell will function identically on any environment Emacs itself runs on.

Emacs Client. EmacsClient allows one to open a file for editing in an already running Emacs. Because it doesn’t start a new Emacs instance at each invocation, you can set up EmacsClient as the default editor, e.g. in the environment variable EDITOR or VISUAL. EmacsClient is part of and works only in conjunction with GNU Emacs.
