i3-msg ā€” send messages to i3 window manager


i3-msg [-q] [-v] [-h] [-s socket] [-t type] [message]


-q, --quiet

Only send ipc message and suppress the output of the response.

-v, --version

Display version number and exit.

-h, --help

Display a short help-message and exit.

-s, --socket sock_path

i3-msg will use the environment variable I3sock or the socket path given here. If both fail, it will try to get the socket information from the root window and then try /tmp/i3-ipc.sock before exiting with an error.

-t type

Send ipc message, see below. This option defaults to "command".


Send ipc message, see below.

Ipc Message Types


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.


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


Gets the current outputs. The reply will be a JSON-encoded list of outputs (see the reply section of docs/ipc, e.g. at https://i3wm.org/docs/ipc.html#_receiving_replies_from_i3).


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


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.


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.


Gets a list of configured binding modes.


Gets the version of i3. The reply will be a JSON-encoded dictionary with the major, minor, patch and human-readable version.


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


# 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



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