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. Some commands operate on the current instance and some on the local instance.

Use the 'help' command to list the available commands.
