AC.15 Running Shell Commands from Emacs

Emacs has commands for passing single command lines to inferior shell processes; it can also run a shell interactively with input and output to an Emacs buffer named `*shell*' or run a shell inside a terminal emulator window.

There is a shell implemented entirely in Emacs, documented in a separate manual. See section `Eshell' in Eshell: The Emacs Shell.

M-! cmd RET

M-| cmd RET

Run the shell command line cmd with region contents as input; optionally replace the region with the output (shell-command-on-region).

M-x shell

Run a subshell with input and output through an Emacs buffer. You can then give commands interactively.
