How can I run bash scripts from emacs and show the result in emacs?

Did you try the shell-command command? If you don’t know what it does, run C-h f shell-command to see the help for it:

shell-command is an interactive and byte-compiled function defined in

(shell-command COMMAND &optional OUTPUT-BUFFER ERROR-BUFFER)

Execute string COMMAND in inferior shell; display output, if any.

With prefix argument, insert the COMMAND's output at point.

Interactively, prompt for COMMAND in the minibuffer.

Type M-x shell and enter your command.

In addtion to M-x shell-command, there is also shell-command-on-region which will pipe the Emacs region into your command and output the results to the Messages buffer.


A fun and esoteric way to see the output of a program in emacs is to use Eshell Redirection.

  1. M-x eshell - Start up eshell
  2. ls /usr > #<buffer *scratch*> - Redirect the output of ls /usr to the *scratch* buffer.
  3. C-x b *scratch* - Switch to the *scratch* buffer to verify the output.

You can also run bash scripts from an Org mode file using babel. Add something like this to your Org mode file:

#+begin_src shell

Pressing C-c C-c on the source block runs the script, producing the following output:

: Fri Oct 28 10:14:18 AM EDT 2022

It can be an arbitrary script, e.g. create a /tmp/my-script file like this:

#! /bin/bash

echo "This is the output of my script"

then make it executable with chmod +x /tmp/my-script and then add the following source block to an Org mode file:

#+begin_src shell

Pressing C-c C-c on the source block produces the following output:

: This is the output of my script

You can read about source blocks in Org mode in the manual with C-h i g(org)RET m Working with source code RET.
