i3-msg

I3-MSG(1)							     i3 Manual								 I3-MSG(1)

NAME

       i3-msg - send messages to i3 window manager

SYNOPSIS

       i3-msg [-t type] [message]

IPC MESSAGE TYPES

       command
	   The payload of the message is a command for i3 (like the commands you can bind to keys in the configuration file) and will be executed
	   directly after receiving it.

       get_workspaces
	   Gets the current workspaces. The reply will be a JSON-encoded list of workspaces.

       get_outputs
	   Gets the current outputs. The reply will be a JSON-encoded list of outputs (see the reply section).

       get_tree
	   Gets the layout tree. i3 uses a tree as data structure which includes every container. The reply will be the JSON-encoded tree.

       get_marks
	   Gets a list of marks (identifiers for containers to easily jump to them later). The reply will be a JSON-encoded list of window marks.

       get_bar_config
	   Gets the configuration (as JSON map) of the workspace bar with the given ID. If no ID is provided, an array with all configured bar IDs
	   is returned instead.

DESCRIPTION

       i3-msg is a sample implementation for a client using the unix socket IPC interface to i3.

EXAMPLES

	   # Use 1-px border for current client
	   i3-msg "border 1pixel"

	   # You can leave out the quotes
	   i3-msg border normal

	   # Dump the layout tree
	   i3-msg -t get_tree

ENVIRONMENT

   I3SOCK
       If no ipc-socket is specified on the commandline, this variable is used to determine the path, at wich the unix domain socket is expected,
       on which to connect to i3.
