>Environment:
System: NetBSD sun-lamp.pc.cs.cmu.edu 1.1A NetBSD 1.1A (SUN_LAMP) #34: Thu Jan 18 20:53:30 EST 1996 cgd@sun-lamp.pc.cs.cmu.edu:/usr/src/sys/arch/i386/compile/SUN_LAMP i386
>Description:
w and uptime normally print system uptime and load in the form:
21:26 up 31 days, 4:36, 5 users, load average: 0.01, 0.04, 0.05
More generally, that's:
<date> up <time incl. commas>, <n> user[s], load average: <averages>
However, if the system has been up for less than a minute, it'll
print something like:
21:26 up, 1 user, load average: 0.15, 0.00, 0.00
I.e. it no longer prints _anything_ for the 'up time'.
This confused me (i had to look at the output a couple of times to
realize what happened). From talking to others about it, apparently
i'm not along in thinking the output format odd. I've no doubt
that the machine is _up_, since i just ran a command... 8-)
>How-To-Repeat:
boot a fast machine, and log in, and run 'uptime' or 'w'. If
the machine has been up for less than a minute, note that it
simply says "up," rather than including the amount of time
that it's been up.
