X11: genera una finestra esistente tramite la riga di comando?

Question

Dato un ID di finestra del client X, c'è un modo per sollevare quella finestra dalla riga di comando?

$ xlsclients -a 
Window 0x3000001: 
    Machine: ohm 
    Name: Terminal 
    Icon Name: foo 
    Command: foo 
    Instance/Class: foo/bar 

$ xraise -id 0x3000001 <-- this is what I would like to do 

Answer 1

È anche possibile utilizzare wmctrl, che fa cose simili
