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*'.

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.
