Синопсис (Synopsis)
uptime [options]
Описание (Description)
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.
This is the same information contained in the header line
displayed by w(1).
System load averages is the average number of processes that are
either in a runnable or uninterruptable state. A process in a
runnable state is either using the CPU or waiting to use the CPU.
A process in uninterruptable state is waiting for some I/O
access, eg waiting for disk. The averages are taken over the
three time intervals. Load averages are not normalized for the
number of CPUs in a system, so a load average of 1 means a single
CPU system is loaded all the time while on a 4 CPU system it
means it was idle 75% of the time.
