Is there a fast way (keyboard shortcut) to open a terminal emulator (in my case urxvt) in the same directory as the file in the current emacs buffer?

The combination M-! allows you to launch shell commands. You could use it to launch a separate urxvt.

M-! urxvt RET

I just tried it with xterm (I don't have urxvt) and it did open in the same directory as the file in the buffer.

If you want to define a shortcut add something similar in your init file:

(global-set-key (kbd "C-c s") (kbd "M-! urxvt RET"))

In my case I bound the shortcut to: Ctrl+C - S.

I usually use M-x term.

You can also checkout:

  • M-x terminal
  • M-x shell

M-x term is effectively launching a terminal emulator written in elisp. From the help:

term
M-x ... RET Start a terminal-emulator in a new buffer. (term PROGRAM)

term is an interactive compiled Lisp function in `term.el'.

Start a terminal-emulator in a new buffer. The buffer is in Term mode; see `term-mode' for the commands to use in that buffer.

Type C-c b to switch to another buffer.

  • Thanks, I didn't know M-x term, it seems nice but is not exactly what I want. I want to start not a shell (for example bash or zsh in an emacs buffer but a terminal emulator (xterm or urxvt...). – student Aug 7 '12 at 12:50
  • @student have a look at multi-term – Ulrich Dangel Aug 7 '12 at 14:10

The emacs command M-x shell will start a shell in a new buffer (or switch to an existing shell buffer, if there is one). If it's a new shell buffer, it'll be started in the directory of the file being visited in the current buffer. If it's an existing shell buffer, it'll still be in the directory where you left it after last using it. In order to always get the behaviour you want, remember to kill the shell buffer when you're done with it (C-x k)

If M-x shell is too much typing, you can set a global key to start a shell for you. Something like (global-set-key (kbd "C-x S") 'shell) in your startup file should do it (but be careful not to mask another useful command with your shortcut!)

I wanted to run a dedicated terminal application, konsole. I wanted to open a new tab in konsole if it is running, or fire-up one if it is not.

Since I was younger back then I split the implementation between emacs and bash. I call the following defun from emacs:

(defun bk-konsoles ()
  "Calls: bk_konsoles.bash -- which starts new tab in a running konsole,"
  (interactive)
  (let ((curDir default-directory))
    (shell-command (concat "bk_konsoles.bash \"" curDir "\" 2>&1 > /dev/null & disown") nil nil)
    (kill-buffer "*Shell Command Output*")))

The defun calls bash script, bk_konsoles.bash:

#!/bin/bash

myPath=`echo $@ | sed 's/.$//'`

runningKonsole=`ps -e | grep konsole`
if [ "$runningKonsole"!="" ]; then
    if [ "$@"!="" ]; then
        konsole --new-tab --workdir "$myPath" 2>&1 > /dev/null
    else
        konsole --new-tab 2>&1 > /dev/null
    fi
    wmctrl -a " – Konsole"
else
    konsole
fi

Most of the time I use shell-mode. So I heavily use shell-here. But when I need external terminal. I use urxvt-client with tmux using this:

  • Create file named 'term-here' in /usr/local/bin/ containing
urxvtc -e bash -c "tmux -q has-session && exec tmux attach-session -d || exec tmux new-session -n$USER -s$USER@$HOSTNAME"
  • Create new function in emacs
(defun term-here ()
  (interactive)
  (start-process "" nil "term-here"))
  • Bind to your favorite key

This will open urxvt-client (with tmux) in your current directory. I bind it in dired-mode-map.

(use-package dired
  :ensure nil
  :ensure-system-package urxvt
  :bind ((:map dired-mode-map
           ("," . term-here))))

I choose urxvt-client because it is fast and simple. Don't forget to run your urxvt-daemon at startup.
