How can I view os_log log entries as they stream from a device using the log tool?

This is a question about Apple’s unified logging and activity tracing system, sometimes known as os_log.



I have an app that will not run in the simulator, but only on device. I want to use os_log to emit logs. I want to view the live stream of logs, not in the Console app, but with the log command line tool, since it provides a more flexible interface for filtering log messages. Is there a way to do this?



A way to view the stream of logs (not files), from a device (not the Simulator), which were created by calls to os_log (not some other system)?
