Around three weeks ago I wrote an article on how to automate mouse and keyboard. It was very fun experience but as the former article was quite long I didn’t mentioned about wmctrl tool. It is an excellent complement to the previously described tools.
I will describe only one usage scenario – How to quickly maximize particular window. To check out more examples look at wmctrl user documentation external article.
Using wmctrl you can list windows in easy way:
$ wmctrl -l 0x04600004 0 milosz-notebook Oracle VM VirtualBox Manager 0x040002dc 0 milosz-notebook sleeplessbeastie's notes — WordPress - Google Chrome 0x01800069 0 milosz-notebook Gnuplot (window id : 0)
Maximize particular window:
$ wmctrl -i -r 0x040002dc -b "add,maximized_vert,maximized_horz"
Restore original dimensions of the previously maximized window:
$ wmctrl -i -r 0x040002dc -b "remove,maximized_vert,maximized_horz"
Toggle maximized_vert and maximized_horz properties:
$ wmctrl -i -r 0x040002dc -b "toggle,maximized_vert,maximized_horz"
wmctrl provides more interesting ways to interact with an X Window manager like switching desktops or moving windows between them so I strongly suggest to read its manual page.
