This command is basically a frontend to the macOS log command, using preconfigured filters suitable for Little Snitch. Use the option --last with a time interval to see messages from the past, or --stream to watch messages live. This command is primarily made for analyzing bugs and unexpected behavior with guidance from our support. If you need this command, our support team will tell you what options and arguments you should use.

Contrary to other commands, the log command is available to non-root users and does not require the Allow access via Terminal setting to be enabled.
