uptime

uptime: tell how long the computer has been running.

Synopsis

uptime [-p]

Description

uptime prints how long the computer has been running since it booted, as procps’s uptime does:

 up 5 min
 up  1:05
 up 2 days,  1:05

Options

-p, –pretty

Says it in words: up 1 hour, 5 minutes.

Exit status

0; 1, with a usage message, for any other argument.

Notes

mcos has no real-time clock, so there is no time of day; and no load average or user count either. The uptime is the machine’s own clock, which stands still while its chunk is unloaded.
