 nbdkit --filter=exitlast PLUGIN

nbdkit-exitlast-filter is an nbdkit filter that causes nbdkit to exit when there are no more client connections.  Note that it doesn't exit before the first client connection.

One use for this is in combination with a superserver, to save resources when nbdkit is not in use (see nbdkit-service(1)). Another use is to ensure nbdkit exits after the client has finished (but see also nbdkit-captive(1) for other ways to do this).

To exit when an event occurs, try nbdkit-exitwhen-filter(1).

There are no parameters specific to nbdkit-exitlast-filter.  Any parameters are passed through to and processed by the underlying plugin in the normal way.

$filterdir/nbdkit-exitlast-filter.so

The filter.

Use nbdkit --dump-config to find the location of $filterdir.

nbdkit-exitlast-filter first appeared in nbdkit 1.20.
