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.

.PP
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.
.SH OPTIONS
.TP
Add -p|--pretty option to uptime(1) for pretty output. This patch adds the -p option to the uptime(1) command, which changes the uptime displayed from something like: 10:35:52 up 2:33, 1 user, load average: 1.69, 1.65, 1.63 to: up 2 hours, 33 minutes I originally implemented this as the up(1) program about 14 years ago. In 2008 or 2009, I created a patch for procps to add this functionality to uptime and submitted it to the project. Never heard from the project and no new releases of procps had been made. Then I found out about this project and decided to port my patch to it. So here it is. This is really just for fun. There is no real technical reason to have this functionality. But even now, 14 years later, I still get emails asking where the source code for up is. So I thought it would be nice for the uptime command on Linux to sport the up functionality by default.
