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.
wmdctrl is a diald control application which can be used in the windowmaker dock. It displays information about a running diald daemon, including the interface name, state, timeout, size of queue, and TX/RX transfer rate bars. There are also a series of buttons for controlling the connection, including bringing it up, down, and docking as well as a button to launch dctrl for more information. wmdctrl is based loosely on dctrl, and on other windowmaker dockapps.
