Last reboot time

In this blog post, we will be discussing four different ways to check the last time your Linux system was rebooted. This information can be useful for troubleshooting purposes, or simply to keep track of how often your system is being rebooted.

We will be using the terminal commands “last,” “who -b,” “uptime -s,” and “dmesg” to obtain this information.

Check the last reboot time with last command in Linux

The best way to check the last reboot time in Linux is using the last reboot command. Open the terminal and type last reboot. It will show all reboots since the log file was created.

To list the last reboot time, run last reboot| head -2.

Example:
# last reboot|head -2
reboot   system boot  4.18.0-348.20.1. Mon Aug 29 08:43   still running
reboot   system boot  4.18.0-348.20.1.

Mon Aug 29 08:27 – 08:38  (00:11)
