after a user login/logout, it hangs in a /usr/libexec/getty process.

not sure it's not doable. others?
I have the same experience.

Yes. I wonder what the correct syntax is.

Open Mac Help and search for "starting up in console mode."

I'd say: Mac Help, shutup now! :p

So I'm curious where chabig got 'sudo shutdown now' from the terminal
would send you to single user mode.
Perhaps by pressing Cmd-S at the moment of reboot?
I'm assuming he's using 'sudo shutdown -r now', since shutdown must know what to do.

About options for shutdown:
I found out by looking at the man page for it on a SCO Unix box,
that it has an optional su argument :
Code:
The optional su argument lets the system go single-user
without completely shutting it down.
(This option is identical to -i1 and is present
for backwards compatibility with XENIX).
and also:
Code:
-i[0156abcsS]

    Specifies the init level to bring the system to (see init(M)).
    By default, the system is brought to level 0.
P.S. yellow, congrats on reaching Hall of Fame status! :cool:

Thanks! 2500 pieces of bad advice and counting! :)

I know for a fact that you can use the terminal to drop into single user mode, from the GUI environment. I've done it.

And I'm 98% sure I did it with sudo shutdown now in 10.2.8 (I got the hint off of this site, actually.)

I can't verify until I get home, though.

EDIT: OK, I don't know if it was single user mode, but it was a similar screen, it was that or >console, or some equivalent.

OK, I just tried it on 10.2.8 and it worked. It dumped you into single user mode. However, it doesn't work for Panther, so you'll have to stick to cmd-s on boot.

chabig 10-28-2003 07:55 PM
There must be a way in Panther...perhaps one of those other command line options.

Hi Chris!
Checked them here (no access to a Mac at the moment).

Could not find how to set runlevels upon reboot, though.
Perhaps a combination of tools would do the trick (sync, reboot, etc.)

Though e.g. SCO Unix can indicate a run level for init to be applied upon reboot (1, s or S for single user),
this apparently is absent from OS X...

Mac OS X 10.3: Starting Up in Console Mode

http://docs.info.apple.com/article.html?artnum=125085

Press the Command and S keys together as the computer starts up.


You can also enter Console mode from within the Terminal application. If you are in Terminal, type:

sudo shutdown now

To switch back to the Mac OS X interface, type reboot and press the Return key. The computer restarts and you see the login dialog or the Mac desktop, depending on your login preferences.

That kbase article is incorrect for 10.3. Try it yourself. That works for Jaguar, but not for Panther. It seems that 'shudown' in the CLI assumes 'shutdown -o'. The man page doesn't mention -o.

sao 10-29-2003 12:45 PM
yellow,

You are absolutely right...and in my Hall of Fame now... :)

Should have read the whole thread... :D

yellow 10-29-2003 12:50 PM
Sao, any idea what the o flag is all about? I only assume that it's the default flag because of:

yellow% sudo shutdown now
Password:
shutdown: -o requires -h or -r
usage: shutdown [-] [-h | -p | -r | -k] [-o [-n]] time [warning-message ...]

But there's no mention in the man pages.. unless there's more then one shutdown?

mervTormel 10-29-2003 01:13 PM
http://www.svbug.com/cgi-bin/man.cgi?comd=8+shutdown

the manpage is out of rev with the dingus, and the dingus may be hobbled on OSX, re: runlevels

sao 10-29-2003 01:56 PM
shots in the dark...

I wonder if the reason that 'shutdown now' doesn't work in Panther has anything to do with journaling being on.

I remember there was a bug also with 'sudo shutdown -h time' in 10.2.8
