How to check for systems shutdown/startup in 12.10?

[Balthier1979]

Hello guys,

I am running the following commands every evening, using crontab

30 23 * * * root rtcwake -m mem -s 23000
15 6 * * * root reboot

I can see from /var/log/auth.log, that something has happened at those times (session closed/session opened), but I can also see the same type of messages at other times, when I know I haven't restarted the computer.

Is there any way I can check just the shutdowns and startups of the computer?
If I check in /var/log/boot.log, I can see some things being started and stopped, but there are no dates and times for when this is occuring.

This will show all reboots since /var/log/wtmp was created

last reboot

Hi

Use the command.

 
last

That will show when users logged in and the machine was rebooted.

You can also check /var/log/syslog.

Kind regards
