The command "last reboot" is used in Unix-like operating systems, such as Linux, to display information about the system's previous reboot.
When you run "last reboot" in the terminal, it generates a log of the most recent system reboots. It provides details such as the date and time of the reboot, as well as the duration since the system last started.
Here is an example output of the "last reboot" command:
reboot system boot 5.4.0-26-generic Sun May 31 14:25 still running
reboot system boot 5.4.0-26-generic Sun May 31 12:00 - 14:25 (02:24)
In this example, it shows that the system last rebooted on May 31 at 14:25 and has been running since then. It also logs the previous reboot that occurred on May 31 from 12:00 to 14:25, with a duration of 2 hours and 24 minutes.
The "last reboot" command is useful for system administrators and users who want to check the history of system restarts, track uptime, or troubleshoot any issues related to system reboots.
