shutdown

I read somewhere that shutdown without any parameter takes you into single user mode. When I try it, I get a usage msg with a list of parameters....

This is on 11.0-RELEASE-p1 i386.

I read somewhere that shutdown without any parameter takes you into single user mode.

     When run without options, the shutdown utility will place the system into
     single user mode at the time specified.

It says without options, not without parameters. Subtle difference.

Without options: shutdown now
Without parameters: shutdown

I'm not sure I understand the subtle difference but anyhow I thought that just running shutdown without anything else (options or parameters) would place the system in single user mode....

In this case a parameter is a time (or the 'now' keyword), options are -h, -p, -r etc.

The easiest way to switch to single user mode is using init(8): init 1
