I would like a way to refresh a specific window from the terminal command-line.
Probably I will need a command 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?
With xte
tool from xautomation
package it is as simple as
xte "key F5"
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.
xrefresh
refreshes all partly- or fully-visible windows, i.e. all windows for which refreshing may have an effect. If it dosen't work for you, then refreshing is not what you're after. It is pretty rare to need to explicitly refresh a window. What problem are you trying to solve? If the problem is that the text inside the terminal is garbled because some background application has written a message, you can't do anything about it at the X level or on the terminal, you need to tell your application inside the terminal to refresh its display.xte

package that I proposed to you here, works flawlessly for me.
