Maybe you're referring to `neo4j-shell`, as the suggested commands have no effect for me with `neo4j console` (Neo4j 2.3.2 Community, OSX 10.11.3). The docs here <http://neo4j.com/docs/stable/re01.html> also state:
console Start the server as an application, running as a foreground process. Stop the server using CTRL-C. And with Ctrl-C, shutdown *appears* to be graceful: $ neo4j console ... 2016-03-06 13:52:33.555-0600 INFO Remote interface ready and available at http://localhost:7474/ quit ^D ^C2016-03-06 13:52:50.748-0600 INFO Neo4j Server shutdown initiated by request ... 2016-03-06 13:52:50.852-0600 INFO Successfully stopped database 2016-03-06 13:52:50.852-0600 INFO Successfully shutdown database On Sunday, March 6, 2016 at 1:25:38 AM UTC-6, Michael Hunger wrote: > > Clean shutdown > > Ie "quit" or ctrl-d > > > > Von meinem iPhone gesendet > > Am 06.03.2016 um 00:47 schrieb Jesse Hemingway <jiro...@gmail.com > <javascript:>>: > > Ok, that certainly works.
