Linux uptime

Linux uptime can be easily found out by the uptime command:

$ uptime
22:19:29 up 10 days, 22:26,  5 users,  load average: 0.00, 0.00, 0.00

The system is up for 10 days, 22 hours and 26 minutes.

uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are currently logged on, and the system load averages for the past 1, 5, and 15 minutes.

The current date and time can be found out by date command:

$ date
