[Super beginner's guide in 1 minute] Done! Checking system uptime for Linux-based OS

Hello!
I'm Inoue, the Persian cat at Beyond Shikoku office.

To put it more elegantly, as an MSP (Managed Service Provider), I frequently use the command "uptime"
. This command checks the system's uptime on Linux-based operating systems.
When a reboot occurs, the "uptime" command tells me when the reboot took place.

uptime command

Check system uptime

[root@test-aws-harukainoue ~]# uptime 07:56:53 up 16 min, 1 user, load average: 0.00, 0.00, 0.00

From left to right : ■ Startup time ⇒ The system was started at 07:56:53 (hour:minute:second) ■ Time elapsed since startup ⇒ 16 minutes have passed since startup ■ Number of logged-in users ⇒ 1 user is currently logged in ■ Load average (1 minute, 5 minutes, 15 minutes) indicating load status ⇒ The " uptime " command showed that there is no load because no processes are running

summary

The " uptime " command has no options. So it seems simple, but if you don't know the " uptime " command, you won't know how to find out when something was started. Even if you type the " uptime " command, if you don't know how to interpret the results, you won't know what to check. It's a command that infrastructure engineers use surprisingly often!

I will continue to experiment and learn through trial and error,
and write blog posts about my favorite commands and commands that I personally want to understand better.

Growing every day, moving forward every day.
I must update myself every single day!!!
Thank you for reading to the end.
