I would like a way to refresh a specific window by the terminal.
Probably I will need a comand to find the id or the name of the window and a command to refresh it.
It looks like
xrefresh cannot do this, how could I do this?
It will act on the current active window, so you'd have to make sure the proper one is selected previously.
You could also use xdotool, which would allow you to do that on a window which hasn't focus too.
