Hi, I poetsd a comment on Toni Anicic’s blog about cron.He’s been very kind and tried to help, but maybe you are the right person for this topic.We are experiencing strange behavior with cron-based.After the two comments in Toni’s blog, we re-queued the newsletter, launched cron via wget and are observing the mail server’s behaviour.Current batch size ($countOfSubscritions) is 20.Right after the cron run, the mail server received 105 e-mails for delivery.How’s it that 20 becomes 105 with a single cron run?

Is it possible to schedule a reboot to boot to live usb instead to take automated disk images?

two cents.

for turning on at the appropriate hour. restart your machine and goto to the bios.

normally you can find something in “power control” or something like that. Here you can write the time you want your machine on. and voila! (ok, ok, … close the menu, probably F10 to save the changes and let the machine restart)

in my case, my machine starts 07:45, so, when I arrive at 08:00 my sistem is ready. And in some cases some work is done in scripts.

For delay an instruction, like shutdown, you can do it in several ways.

only with shutdown, (rtfm) or consult a few lines above this one.

with at

with cron

in both cases, please read the manual, man.!! In fact, you can consult several blogs and web pages to do that. I recommend you thegeeksutff.com, here you can find a brief tutorial and …. examples!

Good luck.

about shutting down another machine.

You can do it with ssh.

First of all. create a script in the machine you want to shutdown. Giving the instructions to shutdown.
Test it.

Now you can type the instruction:

ssh “name/ip of the other machine name-of-the-script”

and … that’s all.

of course you can put the instruction for ssh in your own crontab.
so, you can shutdown automagically one machine or several at your own desire.

Or if you want to schedule a shutdown in the next 24 hours:

shutdown -h time
e.g:
shutdown -h 06:45

Thank you,

untill now didn’t need crontabs, coming from VMS I could not get a hold on this crontab, since this Howto I understand at last, I have read loads of internetsites, man pages, books about it. I must say how can something so simple be described so complex.
I will visit your website more often!

Thanks! I was having trouble wrapping my head around the crontab thing. This showed how to do it (and by extension, how it works).

I didn’t come across usage of shutdown but I have seen examples of user logged off from a machine at particular time. Like in computer training institutes, they used to fix machines for users for a certain duration of time. User comes and uses available machine and once his or her time gets over, it logs off.
