JACK_PROPERTY(1) General Commands Manual JACK_PROPERTY(1) NAME jack_property - JACK client to list, set and delete metadata informa- tion SYNOPSIS jack_property -l jack_property [ -c | -p ] -l identifier jack_property [ -c | -p ] -l identifier key jack_property [ -c | -p ] -s identifier key value [ type ] jack_property [ -c | -p ] -d identifier jack_property [ -c | -p ] -d identifier key jack_property -D DESCRIPTION jack_property can be used to list, set and delete any and all metadata associated with the ports and clients of a JACK server. There are three main ways to use the command. The -l option is used to list existing metadata. The -s option is used to set metadata. The -d/-D options are used to delete metadata. The identifier is normally a UUID (UUIDs for ports and clients can be shown with jack_lsp(1)). If the -c option is used, then identifier will be interpreted as a client name, and its UUID will be looked up inter- nally and used for the relevant metadata operation. If the -p option is used, then identifier will be interpreted as a port name and its UUID will be looked up internally and used for the relevant metadata opera- tion. The key is an arbitrary string that identifies the metadata to be oper- ated upon. The value is an arbitrary string that defines the value of the metadata to be created. The type is an optional MIME type, given as a string. An empty type for a piece of metadata results in it being interpreted as "text/UTF-8". OPTIONS -l list all metadata currently defined -l identifier list all metadata currently defined for identifier -l identifier key show the value of the metadata associated with key for identifier -d identifier deletes all metadata for identifier -d identifier key deletes the metadata associated with key for identifier -D delete all currently defined metadata -s identifier key value [ type ] sets the metadata associated with key to value for identifer, with its type set to type if given -c interpret a given identifier as a client name rather than a UUID -p interpret a given identifier as a port name rather than a UUID 4 2022 JACK_PROPERTY(1)
