Questions tagged [shell-command]
is for executing shell commands from Emacs (the default key binding is `M-!`). Shell output is shown in the echo area if it fits, in buffer `*Shell Command Output*` otherwise. Emacs comes with many supporting facilities for executing shell commands, including interactive execution, selective execution on a region, history cycling, directory tracking, connecting to serial ports, emulator options, and specifying remote hosts.
