Linux Uptime Command With Usage Examples

Uptime is a command that returns information about how long your system has been running together with the current time, number of users with running sessions, and the system load averages for the past 1, 5, and 15 minutes. It can also filter the information displayed at once depending on your specified options.

 

uptime uses a simple syntax:

# uptime [option]

 

Using Uptime

 

You can run the uptime command without any options like so:

# uptime

 

It will display an output similar to:

09:10:18 up 106 days, 32 min, 2 users, load average: 0.22, 0.41, 0.32

 

In order of appearance, the command displays the current time as the 1st entry, up means that the system is running and it is displayed next to the total time for which the system has been running, the user count (number of logged on users), and lastly, the system load averages.

You can filter uptime’s result to show only the running time of the system with the command:

# uptime -p

up 58 minutes

 

Check Linux Server Starting Time

 

Using option -s will display the date/time since when the system has been running.

# uptime -s
