uptime(1) — Commands
NAME
uptime − Shows how long a system has been running
SYNOPSIS
uptime [−m]
The uptime command displays the current time, the amount of time since the system was last started, the number of users logged into the system, and the load averages.
OPTIONS
−mPrints the Mach factor instead of the load average.
DESCRIPTION
The display of the uptime command is identical to the heading of a w command display.
The load average numbers give the number of jobs in the run queue for the last 5 seconds, the last 30 seconds, and the last 60 seconds. The Mach factor is a variant of the load average, given for the same intervals; the closer its value to 0, the higher the load.
