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.

Go to the first, previous, next, last section, table of contents.
