When interacting with the operating systems I always use Eshell because it integrates seamlessly with Emacs, supports (remote) TRAMP file names and also works nice on Windows.
After starting shell commands (like long running build jobs) I often lose track the task when switching buffers.
Thanks to Emacs hooks mechanism you can customize Emacs to call a elisp function when an external command finishes.
I use John Wiegleys excellent alert package to send desktop notifications:
(require 'alert) (defun eshell-command-alert (process status) "Send `alert' with severity based on STATUS when PROCESS finished." (let* ((cmd (process-command process)) (buffer (process-buffer process)) (msg (format "%s: %s" (mapconcat 'identity cmd " ") status))) (if (string-prefix-p "finished" status) (alert msg :buffer buffer :severity 'normal) (alert msg :buffer buffer :severity 'urgent)))) (add-hook 'eshell-kill-hook #'eshell-command-alert)
alert rules can be setup programmatically. In my case I only want to get notified if the corresponding buffer is not visible:
(alert-add-rule :status '(buried) ;only send alert when buffer not visible :mode 'eshell-mode :style 'notifications)
This even works on TRAMP
buffers. Below is a screenshot showing a Gnome desktop notification
