Uptime

The uptime command typed at the command line in a terminal, will show:


 * The current time,
 * The time this machine has been up and running (in hours, days, etc),
 * How many shell instances are running (the number of users),
 * And finally the load average.

Example: $ uptime 3:09pm up 3 days 17:31,  6 users,  load average: 0.22, 0.15, 0.05 In this example, the computer has not been powered off since 3 days and 17 hours. There are 6 users logged in.
