Is there a GNOME extension which can run a specific command and update its output as status in GNOME panel?

Question

To give an example, I run series of commands which would output a number. I must show this on the GNOME panel. Font, color, size etc doesn't matter. I just need a small display on the panel.

Answer 1

There are a couple of extensions you might want to have a look at.

1. Top Bar Script Executor

   Adds buttons to the top bar that execute scripts or commands.

2. Command Output

   Display the output of a shell command at a user-specified interval.

Answer 2

Executor by raujonas, logo has a Sigma sign on it

does exactly what you want - I use it to ping a server and display and Up/Down arrow in the panel. Install via https://extensions.gnome.org/ or use Tweaks > extensions

Answer 3

There is also Argos (and here's an article about it).
