The “uptime” command is one of the most common commands I use. This command is used to check the system uptime of Linux-based OS. For example, this command can tell you when the system is rebooted in case you need to check when it happened.
Check the system's uptime.
[root@test-aws-beyond ~]# uptime 07:56:53 up 16 min, 1 user, load average: 0.00, 0.00, 0.00
The current time that the system is booted
→The system is booted at 07:56:53 (hour:minute:second)
The amount of time since the system is started
→It’s been 16 minutes since it is started
Number of logged in users
→1 user is logged in now
Load average for the load status (1 minute, 5 minutes, 10 minutes)
→There is no load because none of the processes are running at this point
The “uptime” command showed the details like the above.
There is no option for “uptime” command.
Therefore it seems easy to use but you have to know how to read the result to find whatever you are looking for.
