pw-cli(1) General Commands Manual pw-cli(1)
NAME
pw-cli - The PipeWire Command Line Interface
SYNOPSIS
pw-cli [command]
DESCRIPTION
Interact with a PipeWire instance.
When a command is given, pw-cli will execute the command and exit
When no command is given, pw-cli starts an interactive session with the
default PipeWire instance pipewire-0.
Connections to other, remote instances can be made. The current instance
name is displayed at the prompt.
Note that pw-cli also creates a local PipeWire instance. Some commands
operate on the current (remote) instance and some on the local instance,
such as module loading.
Use the 'help' command to list the available commands.
GENERAL COMMANDS
help | h
Show a quick help on the commands available. It also lists the
aliases for many commands.
quit | q
Exit from pw-cli
MODULE MANAGEMENT
Modules are loaded and unloaded in the local instance, thus the pw-cli
binary itself and can add functionality or objects to the local
instance. It is not possible in PipeWire to load modules in another
instance.
load-module name [arguments...]
Load a module specified by its name and arguments in the local
instance. For most modules it is OK to be loaded more than once.
This command returns a module variable that can be used to unload
the module.
The locally module is not visible in the remote instance. It is not
possible in PipeWire to load modules in a remote instance.
unload-module module-var
Unload a module, specified either by its variable.
OBJECT INTROSPECTION
list-objects
List the objects of the current instance.
Objects are listed with their id, type and version.
info id | all
Get information about a specific object or all objects.
Requesting info about an object will also notify you of changes.
WORKING WITH REMOTES
connect [remote-name]
Connect to a remote instance and make this the new current instance.
If no remote name is specified, a connection is made to the default

The special remote name called internal can be used to connect to
the local pw-cli PipeWire instance.
This command returns a remote var that can be used to disconnect or
switch remotes.

Disconnect from a remote instance.
If no remote name is specified, the current instance is
disconnected.

DEVICE MANAGEMENT
create-device factory-name [properties...]

Properties are key=value pairs separated by whitespace.
This command returns a device variable.
LINK MANAGEMENT
create-link node-id port-id node-id port-id [properties...]
Create a link between 2 nodes and ports.
Port ids and Node ids can be set to - to automatically select a node
