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.
