The wmctrl program is a command line tool to
interact with an EWMH/NetWM-compatible X Window
Manager. It provides command line access to almost all the features defined in the EWMH specification. It's possible to, for example, obtain information about the window manager, get a detailed list of desktops and managed windows, switch and resize desktops, change the number of desktops, make windows full-screen, always-above, or sticky, and activate, close, move, resize, maximize, and minimize them. The command line access makes it easy to automate these tasks and execute them from any application that is able to run a command in response to some event.
