From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is there a simple GUI application alerting the user when a process is not running? (lemmy.ml)

Is there a simple GUI application that will monitor running processes periodically and alert the user when a process is not running? The ones I have found are far too complex (eg Monit). I am sure this is trivial to achieve with a script, but I'd rather use a GUI.

A use case would look like this: every 60 minutes check if Syncthing is running and display a notification if it's not. In my experience, Syncthing is very reliable when it launches successfully but there may be an issue with conflicting versions that may prevent it from running at boot. Syncthing has no way to alert the GUI user when something goes wrong and you may find after you left home that your laptop hasn't synced. Checking manually is a headache, prone to errors and goes against the idea of fit and forget.

1-liner would be something like watch -n 10 "pgrep konsole || kdialog --msgbox 'konsole no running'"

namely :

watch to repeat a command at interval, e.g. every minute (could also be crontab)
pgrep to check if a process is running
kdialog on KDE to send a message to the current user (plenty more ways)

You learn something new every day here ;) The good thing about kdialog is you can't miss it. Thanks.

With pleasure. I discovered kdialog just recently too as until now I used notify-send but as you are using KDE this gives you a lot more options.

If you are into this kind of things check also dbus or KWin, there are a LOT of fun and powerful ways to interact with KDE.
