NAME

pw-link - The PipeWire Link Command

SYNOPSIS

pw-link [options] -o-l [out-pattern] [in-pattern]

pw-link [options] output input

pw-link [options] -d output input

pw-link [options] -d link-id

DESCRIPTION

List, create and destroy links between PipeWire ports.

COMMON OPTIONS

-r | --remote=NAME

The name the remote instance to monitor. If left unspecified, a connection is made to the default PipeWire instance.

-h | --help

Show help.

--version

Show version information.

LISTING PORTS AND LINKS

Specify one of -o, -i or -l to list the matching optional input and output ports and their links.

-o | --output

List output ports

-i | --input

List output ports

-l | --links

List links

-m | --monitor

Monitor links and ports. pw-link will not exit but monitor and print new and destroyed ports or links.

-I | --id

List IDs. Also list the unique link and port ids.

-v | --verbose

Verbose port properties. Also list the port-object-path and the port-alias.

CONNECTING PORTS

Without any list option (-i, -o or -l), the given ports will be linked. Valid port specifications are:

port-id

As obtained with the -I option when listing ports.

node-name:port-name

As obtained when listing ports.

port-object-path

As obtained from the first alternative name for the port when listing them with the -v option.

port-alias

As obtained from the second alternative name for the ports when listing them with the -v option.

Extra options when linking can be given:

-L | --linger

Linger. Will create a link that exists after pw-link is destroyed. This is the default behaviour, unless the -m option is given.

-P | --passive

Passive link. A passive link will keep both nodes it links inactive unless another non-passive link is activating the nodes. You can use this to link a sink to a filter and have them both suspended when nothing else is linked to either of them.

-p | --props=PROPS

Properties as JSON object. Give extra properties when creaing the link.

DISCONNECTING PORTS

When the -d option is given, an existing link between port is destroyed.

To disconnect port, a single link-id, as obtained when listing links with the -I option, or two port specifications can be given. See the connecting ports section for valid port specifications.

-d | --disconnect

Disconnect ports

EXAMPLES

pw-link -iol

List all port and their links.

pw-link -lm

List all links and monitor changes until pw-link is stopped.

pw-link paplay:output_FL alsa_output.pci-0000_00_1b.0.analog-stereo:playback_FL

Link the given output port to the input port.

pw-link -lI

List links and their Id.

pw-link -d 89

Destroy the link with id 89.
