How do I find the last logged system boot and shutdown times?

Question

I'm a Rails developer working on a web application on Ubuntu Server 10.04. Due to internal requirements, I was asked to find the last 10 system boot and shutdown times... I have no clue where to find these details. Could someone help me out?

Use the last command.

last -x | grep shutdown
last -x | grep reboot

You can pipe this to the head to read the last n instances. For example, in your case:

last -x | grep shutdown | head -n 10

You also should set

BOOTLOGD_ENABLE=Yes

in the /etc/default/bootlogd file (it could be No by default).

I have no /etc/default/bootlogd on my Ubuntu 16.04.2 – Vadim Kotov Oct 24 '17 at 14:58
More on how to enable bootlogd, which is not necessary as of Debian Wheezy (i.e. as of Ubuntu 11.10 -- or so seems likely). – mathandy Feb 17 '18 at 00:24

For a GUI method you can use hardinfo as described here: Does Ubuntu have a "device manager" equivalent? And what is an easy way to access USB drives?.

Under the section Boots you will see this:

Installation is straight forward using:

sudo apt install hardinfo

For some reason it displays only the latest boot in my case – Vadim Kotov Feb 03 '20 at 08:31
@VadimKotov When you type hardinfo from the command line do you see errors as in this bug report? https://bugs.launchpad.net/ubuntu/+source/hardinfo/+bug/1473142 – WinEunuuchs2Unix Feb 03 '20 at 11:40
Nope, it displays only this: Gtk-Message: 17:54:10.696: Failed to load module "canberra-gtk-module" – Vadim Kotov Feb 03 '20 at 14:55
