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

Hello!
This is Inoue, a Persian cat from Beyond Shikoku Office.

To put it simply, the command I use often as an MSP when responding to system failures is " uptime ."
is a command to check the system uptime of Linux-based operating systems.
When there is a reboot, you can use the " uptime " command to find out 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 the left:
■ Start-up time
⇒ The system was started at 07:56:53 (hours:minutes:seconds)
■ Time elapsed since startup
⇒ 16 minutes have passed since startup
■ Number of logged-in users
⇒ 1 user is currently logged in
■ Load average indicating the load situation (1 minute, 5 minutes, 15 minutes)
uptime " command showed
that there were no particular processes running and therefore no load was being applied

summary

" uptime " command does not have any options.
So, although it may seem simple,
if you don't know the
" uptime Even if you type the
" uptime It's a command that infrastructure engineers use surprisingly often!

continue to experiment and
write blogs about my favorite commands and commands that I personally want to understand better.

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