The uptime is the amount of time the Linux system has been continuously running since the last restart. Let’s learn how to check Linux uptime using the uptime command.
To display uptime, just type uptime and press enter. Root privileges are not necessary to perform this check.
If you want to display the uptime in pretty format, use the uptime command with -p command line option.
$ uptime -p
up 1 day, 7 hours, 5 minutes
If you want to specifically display just the date and time since when the Linux system has been running, use the uptime command with -s command line option.
$ uptime -s
2020-09-14 18:00:05
Use the uptime command with -V command line option to display the version information.
$ uptime -V

$ uptime -h
