script to force sleep?

OK, I thought of another possible way to get my silly iMac to sleep after I log out. Maybe there's some way to run a script at logout time (or start up a cron job?) that will make the darn Sleep function work?

The reason I ask is that, while my mac will sleep if I select Sleep from a menu or from the login screen, the EnergySaver / PowerManagement system utterly fails to put the machine to sleep after I log out, regardless of the delay times or other settings.

thanks Carl

Try playing around with pmset, and even see if you can figure out the problem.

Have a look at "LoginWindow Manager", available via VersionTracker.
This utility will allow you to set a script to run at login a/o logout time.

I've done that. Problem is that no matter what settings I choose (from the Preferences GUI or from pmset on the command line), the computer won't go to sleep on its own.

That looks like a great tool.

So, now all I need is the actual name of the shell command that will sleep the computer. (as opposed to pmset, which just sets parameters for whatever does the sleep actions).

The shell command "osascript" will run an AppleScript and the AppleScript statement 'Tell application "Finder" to sleep' will put the computer to sleep. Putting them together is a straightforward task and a worthwhile learning experience.

Why do you want to do this?

I'm wondering if another approach will do what you need conveniently. For instance, if the idea is that nobody could get into your computer by just waking it up (because you had been logged out and they would need to log in) you could just set the machine to require a password on wake from sleep.

If I haven't guessed your reason correctly, it could still be true that understanding why you want to do this would help in providing a different solution.

Thanks, Tom. That's exactly what I needed (osascript).

Of course, perversity has attacked :-) Turns out that, at least for every account other than mine, my computer is sleeping just fine. I have to go track down the offending APE or PrefPane or daemon, I guess.

And to answer someone else's question: I want to have my Mac put itself to sleep after logging out just to save energy and alleged wear&tear.
It's just one of those anal-compulsive quirks that I'd like the machine to do what it's supposed to (as opposed to my manually clicking the "sleep" button on the Login screen).

I've made a little shell script that takes care of the real problem in a proper way. :-) I offer it here to the world. I've packaged it in a loop so it can just be run. Others may want to use cron instead of the while loop (and take away the voices :).

set -- $(pmset -g | grep sleep) SLEEPLIMIT=$2

IDLESECONDS=$((ioreg -c IOHIDSystem | sed -e '/HIDIdleTime/ \ !{ d' -e 't' -e '}' -e 's/.* = //g' -e 'q' / 1000000000)) (( IDLEMINUTES= $IDLESECONDS / 60 ))

if (( $IDLEMINUTES > $SLEEPLIMIT )) then say "Yo! Computer has been idle for $IDLEMINUTES minutes. It should have gone to sleep after $SLEEPLIMIT. Sweet Dreams!"

osascript -e 'Tell application "Finder" to sleep'
sleep 15.sandman.waking_up # wait till it comes to
IDLESECONDS=$((ioreg -c IOHIDSystem | sed -e '/HIDIdleTime/ \ !{ d' -e 't' -e '}' -e 's/.* = //g' -e 'q' / 1000000000))
if (( $IDLESECONDS > 15 ))
then
say "Computer is waking up.  Doo something now or remain idle!"
sleep 10.sandman.do_something.$IDLESECONDS:$IDLEMINUTES

What? Is this some idiosyncratic syntax for when running with a shell trace?
