NAME

       jack_property - JACK client to list, set and delete metadata information

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
       internally  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 operation.

       The key is an arbitary string that identifies the metadata to be operated 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
