(emacs)Shell


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.  Note: Eshell.

`M-! CMD <RET>'
     Run the shell command line CMD and display the output
     (`shell-command').

`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.

`M-x term'
     Run a subshell with input and output through an Emacs buffer.  You
     can then give commands interactively.  Full terminal emulation is
     available.

`M-x eshell'
     Start the Emacs shell.
