The variable > shell-command-switch seems to be a good option to achieve this, just > look into simple.el. The key word in that sentence is _interactive_. I was labouring under the mistaken assumption that requesting a login shell was the way to source my ~/.bashrc (via my ~/.profile), but it turns out the '-i' switch is what's required. ---------------- ~/.bashrc ---------------- alias ll="ls -al" ---------------- ~/.bashrc ---------------- $ bash -l -c ll bash: ll: command not found $ bash -i -c ll [...] # success! shell-command as it stands will not suffice because shell-command-switch can only hold a single switch (and here I need two; -i and -c) but I never expected to be able to use shell-command directly anyway. Here's my function at last (which I've chosen to call interactive-shell-command because you're not restricted to using aliases: (defun interactive-shell-command (command) (interactive "sCommand: ") (set-buffer (get-buffer-create "*Shell Command Output*")) (erase-buffer) (let ((exit-code (call-process "/bin/bash" nil t t "-i" "-c" command))) (if (> (buffer-size) 0) (display-buffer (current-buffer)) (when (eq exit-code 0) (kill-buffer nil) (message "(Shell command succeeded with no output)"))))) Thanks to all for their suggestions.
