Hi,
I liked this idea better, so I settled with this:
# Status Bar Info
status() {
echo -n $(acpi) '|' $(ps -eo pcpu,ucmd --sort -pcpu | sed -n
2,4p | awk '$1 > 10 {print $1 " (" $2 ")"}') '|' $(uptime | sed
's/.*://; s/,//g') '|' $(date)
}
I'm showing the first 3 processes if they happen to be using more than 10%.
Thanks to all who contributed to this discussion.
Jesus.

you should use ps rather than top
here's my status bar scripts including one that shows all processes
using more than 50% CPU:
(
bar=9batt
while :
do
if acpi_available
then
string=`acpi -b | grep discharging | sed 's/.* \(.*%\),
\(.*\):.*/\1 \2/'`
else
string=`apm | sed 's/.* \(.*%\)/\1/'`
fi
if [ -z "$string" ]
then
wmiir remove /rbar/$bar 2>/dev/null
else
echo "$WMII_NORMCOLORS" | wmiir create /rbar/$bar
echo -n "$string" | wmiir write /rbar/$bar
fi
sleep 60
done
) &
(
clock=8clock
echo "$WMII_NORMCOLORS" | wmiir create /rbar/$clock
while date '+%d %R' | wmiir write /rbar/$clock; do
sleep `expr 60 - \`date '+%S'\``
done
) &
(
log=7log
tail -F /var/log/messages | while read line
do
string=`echo -n $line|cut -d " " -f 5-`
if [ "$string" = "-- MARK --" ]
then
wmiir remove /rbar/$log 2>/dev/null
else
echo "$WMII_NORMCOLORS" | wmiir create /rbar/$log
echo -n "$string" | wmiir write /rbar/$log
sleep 1
fi
done
) &
(
top=3top
while :
do
string=`ps -eo pcpu,ucmd --sort -pcpu|tail -n +2|awk 'BEGIN
{ORS=" "}; $1 > 50 {print $2 " " $1}'`
if [ -z "$string" ]
then
wmiir remove /rbar/$top 2>/dev/null
else
echo "$WMII_NORMCOLORS" | wmiir create /rbar/$top
echo -n "$string" | wmiir write /rbar/$top
fi
sleep 10
done
) &

This should echo the right cpu usage...top -n 1 seems to be not
right(sometimes?).
We also had another Way of doing it, probably more reliable, but i am
sorry, i can't tell you that. It has to do something with /proc/stat,
but for me this was enough.
The only real problem I have with this is that the wall time of
top -n 1 is ~.5sec on my machine, and it has to compute a lot of
data other than overall CPU utilization. I don't think it's
suitable for a status script when used as such.

Re: [wmii] Adding cpu usage to status bar
Hey,
You need the '-b' Option for top, because it's not for the Terminal.
We talked long about that in the IRC Channel, we came to this:
top -b -d 1 -n 2|grep Cpu|awk 'BEGIN { FS = " " } { print $2 }'|tail
-n 1 | sed 's/us,//g')
This should echo the right cpu usage...top -n 1 seems to be not
right(sometimes?).
We also had another Way of doing it, probably more reliable, but i am
sorry, i can't tell you that. It has to do something with /proc/stat,

[wmii] Adding cpu usage to status bar
Hi,
I was trying to modify the status bar to add cpu % usage. The easiest
way I found (or so I thought) was this, which works in the command
line:
je...@localhost:~$ top -n 1 | awk 'NR==3 {print $2}'
1.9%us,
(I will massage $2 later to remove the us and the comma, but for now
it was enough as a test),
but when I add it like this to my wmiirc:
status() {
echo -n $(acpi) '|' $(top -n 1 | awk 'NR==3 {print $2}') '|'
$(uptime | sed 's/.*://; s/,//g') '|' $(date)
}
it doesn't work. It shows an empty space between the two |. (the
status function is the one called in the original wmiirc)
Anybody can give a hint at what might be going on, or have a better
idea on how to show the cpu % usage?
Thanks,
Jesus.
