Intro To 'uptime' Command In Linux

2023-05-27 - By Robert Elder

I use the 'uptime' command to see how long the computer has been running since it booted up:

uptime

 14:45:04 up  5:28,  1 user,  load average: 0.85, 1.13, 1.32

The 'uptime' command also shows other useful information like the current time ('14:45:04' in the output above), the number of users that are currently logged in ('1 user' in the output above), and several measures of the average CPU load ('load average: 0.85, 1.13, 1.32' in the output above).

You can use the '-p' flag to see a more clear description of how long the system has been running for:

uptime -p

up 5 hours, 29 minutes

You can use the '-s' flag to see the exact date and time when the system was started:

uptime -s

2023-05-24 09:16:20

And that's why the 'uptime' command is my favourite Linux command.
