how to send lines of a shell script directly to the shell

how to send lines of a shell script directly to the shell

[Uwe Brauer]

Hi

I have to execute a series of commands like 

git checkout strings 
mygit-push-named-branch strings
etc

It is a list of these commands in a file. I can call 
M-x shell 

And then copy each line to the shell where it is executed.

Is there any faster way, a command like
execute this line via the shell.

I googled but cannot find anything.

Regards

Uwe Brauer

Ask your Emacs, not Google. Emacs is your friend, Google isn't :)

c-h a (apropos) shell suggests shell-command-on-region, usually
bound to M-|

(of course, you'd have to mark the line; automating that is left
as an...)

I tried this command out, before asking 😉
but this does not work, I mark the region

Run it and the mini-buffer asks:

shell-command-on-region

And you have to specify the command.


So that is thought that you run a already defined command on some
region.

But this is not what I want.

I want to send a certain line to the shell so that it is executed.

With a bit better search I obtained

https://stackoverflow.com/questions/6286579/emacs-shell-mode-how-to-send-region-to-shell

Which does what I want

Oh, sorry, it was the other way around. We could, of course,
weasel our way out by specifyng /bin/sh or /bin/bash in the
minibuffer, but that's not what I meant ;-)

Hi Uwe,

take a look at this too:

  http://anggtwu.net/eepitch.html
  http://anggtwu.net/eepitch.html#trying-it
  http://anggtwu.net/emacsconf2021.html

The instructions at the "Trying it" are very simple and there's a very
nice demo in the first 30 seconds of my presentation at the
EmacsConf2021. The easiest way to watch it with subtitles is here,

  http://www.youtube.com/watch?v=qM0Luz78qGw

and the easiest way to create the 3-line block that sets up the target
buffer is explained here:

There are several solutions there, you don't mention which you chose.

Anyhow, I recommend keyboard macros. That is generally much faster than
any alternative...if I find myself using a keyboard macro repeatedly,
then I will invest time in finding or writing a better alternative.

Alternatively, org-mode can do pretty much what you want.

This one

(defun sh-send-line-or-region (&optional step)
  (interactive ())
  (let ((proc (get-process "shell"))
        pbuf min max command)
    (unless proc
      (let ((currbuff (current-buffer)))
        (shell)
        (switch-to-buffer currbuff)
        (setq proc (get-process "shell"))
        ))
    (setq pbuff (process-buffer proc))
    (if (use-region-p)
        (setq min (region-beginning)
              max (region-end))
      (setq min (point-at-bol)
            max (point-at-eol)))
    (setq command (concat (buffer-substring min max) "\n"))
    (with-current-buffer pbuff
      (goto-char (process-mark proc))
      (insert command)
      (move-marker (process-mark proc) (point))
      ) ;;pop-to-buffer does not work with save-current-buffer -- bug?

"list of commands in a file" = "shell script"

Make <file> executable by

$ chmod a+x <file>

and execute it

$ ./<file>
