nbdkit-exitlast-filter - Man Page

exit on last client connection

Synopsis

 nbdkit --filter=exitlast PLUGIN

Description

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).

Parameters

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.
