Thanks to both.

I took the one-liner challenge and came up with these little horrors for %Mem &

backtick 1 60 60 awk '{if ($1=="MemTotal:") mt = $2; if ($1=="MemFree:") mm =
$2; if ($1=="Buffers:") mb = $2; if ($1=="Cached:") mc = $2} END {printf
("%2.1f"), ((mt-(mm+mb+mc)) * 100 / mt);print "%M"}' /proc/meminfo

backtick 2 60 60 awk '{if ($1=="SwapFree:") fs = $2; if ($1=="SwapTotal:") ts =
$2} END {printf ("%2.1f"),((ts-fs) * 100 / ts );print "%S"}' /proc/meminfo

I'd never used awk before .. no excuse of course .. but that would explain it
now wouldn't it.. :-)

I wrapped the two above so as not to bother anybody, but at present they are
one-liners in my screenrc.  I'll check later if I can use backslashes to escape
the newlines w/o screen or awk getting their knickers in a twist.

As to %CPU, I couldn't find anything useful in /proc, so I tried the following
at the bash prompt:

ps aux | awk '{if ($3 !="%CPU") t += $3} END {printf "CPU %2.2f", t; print "%"}'

Gives me a printable result .. but ..  the trouble is, I'm not sure at all this
is conceptually correct.

I'm beginning to think I don't really understand the meaning of nn% CPU at all!

I haven't turned it into a screenrc backtick yet ..  For one thing, I'm not
sure screen's backticks support pipes.. if I need quotes .. etc.

I'm also looking for something that would help monitor network traffic .. Not
sure this makes sense, but I was thinking something that displays UP/DOWN Kb's,

Not sure where I could get that from.

And Aaron, thanks for the screenshot and matching scripts.  Once you are given
a shove in the right direction the programming is not difficult .. but coming
up with a clear efficient display of your data with the limited capabilities of
text mode is a different story. So that's going to help considerably. I only
saw your post a few minutes ago .. but I will review the material carefully
tomorrow and see if I can come up with something similar that does what I want.

Thank You!
