Get a list of open windows in Linux

Question

ps ax shows all the running processes. I want to do something similar, but instead of the names of the actual processes, I want the window names listed instead. What Linux command will do this?

Answer 1

wmctrl -l may be what you're looking for. The wmctrl program can also perform some simple actions on the windows like moving them around and setting their properties.

Answer 2

xlsclients shows the running clients and xwininfo -root -children shows all children of the root window. That also includes some stuff your window manager or desktop renders.
