Thanks to the 52 who replied to my request for help in setting up an
auto-shutdown script. Almost everyone reminded me to redirect i/o and
to background. So I set up a simple one line script
/etc/shutdown $* </dev/null >& /dev/null &
called qshutdown, and now I can use
do_to_all qshutdown -k +12 for testing
One reply worth passing on was a neat system for quiet rebooting.
From: email@example.com (Margen Metcalfe)
I saw your posting about shutting down other machines. This is how we
reboot other machines:
Each machine has an entry in a cron file (/usr/adm/daily) that says
if [ -f /tmp/rebootplease ]; then
Then when we want to reboot them all at once we rdist a /tmp/rebootplease
file to them and cron takes care of it sometime in the night.
What I really needed was a way to shutdown and restart all the clients
easily without touching them (they are scatted all over the building,
mostly in locked offices.) Now I can kill rarpd, do a shutdown -r
by the above, and when ready, let the system come up. It really jams the
network when everymachine tries to boot at once, but they seem to work it out.
