Need a script to get load

Derek_59 — Wed, 16 Jun 2004 05:52:53 GMT

right now I am using w to get the load running it every 5mins.

What I want is to just filter out the load numbers and paste that into a certain spot in an html file.

Is there a way I can do this?

Derek,
Is this what you are looking for:

#!/usr/bin/ksh
while true
do
echo `w -u' >> filename
sleep 300
done

Regards,

Derek,

echo `w -u' >> filename

This line has back quotes `w -u`

Well here's a sily way of doing it

$LOAD=`uptime | cut -c45- | sed "s/,//g"`

Mark,

reduce the number 45 until it chops off the correct number of characters. On my system that is 25.

sweet, now I will just do an SSI to insert it into an html page.

Thanks to both of you!

And now for something completely different - a man with awk:

uptime | awk '{print $10, $11, $12}' |sed s/,//g

After years of scripting, I try to stay away from cut -c because the column numbers do not remain stable on many commands and cut's -d does not understand white space as a field (cut -d " " counts every space as a separate field). Geoff's solution is the most stable since changes to the number of spaces between fields can change but awk will always extract fields 10,11,12.

I'm with Bill,
Just use awk to strip the fields you need, you can use head or tail to remove the header information.

I'm with Bill too. This is the reason I called it a "silly" way but I obviously can't spell "silly" properly :)
