30

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](https://wiki.debian.org/bootlogd), which is not necessary as of Debian Wheezy ([i.e. as of Ubuntu 11.10](https://askubuntu.com/questions/445487/what-debian-version-are-the-different-ubuntu-versions-based-on) -- 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
