i3-msg - send messages to i3 window manager
i3-msg "message"
i3-msg is a sample implementation for a client using the unix socket
IPC interface to i3. At the moment, it can only be used for sending
commands (like in configuration file for key bindings), but this may
change in the future (staying backwards-compatible, of course).
i3-msg "bp" # Use 1-px border for current client
