How to list machine startup times

[arcull]

Hi everyone.

I wonder if it is possible to list let's say last 10 machine startup dates and times somehow, are there any kernel logs which I could parse to get them? Any advice welcome, thanks

the command 'last' will show you a list of last logged in users,
'last reboot' will give you the reboot times. I only get two when I use that command. I don't know how to get any more than that.

'last' parses the file /var/log/wtmp. There may be a /var/log/wtmp.1 which should be older and may have more boot times in it.

Aha! 'last reboot -f /var/log/wtmp.1' on my system shows the last 15 reboots!

it is not actually about startups, but is still very useful, thanks

The syslog file has all startups in the file before it is rotated, or you can simply write a script that runs in /etc/rc.local to record each startup.
