awesome-client — awesome window manager remote execution
awesome-client is a remote command line interface to awesome. It communicates with awesome via D-Bus, allowing remote execution of Lua code.
awesome-client reads commands from standard input and sends them via D-Bus to awesome. If rlwrap is installed, it will be used to provide a readline command line interface.
The awful.remote module has to be loaded if you want this command to work.
