Question

I need daemon script which every 3 seconds call command: cat /proc/stat > /some/file

can anybody help me how make and setup this? (system is debian squeeze)

Answer 1

like this?

#!/bin/sh
while true
do
   cat /proc/stat > /some/file
   sleep 3
done

and run it with /path/to/scrip.sh &

(use the trailing & to run it in the background, that is: “daemon” mode)

it’s not very sophisticated (e.g. the only awy to stop it once it’s started is by killing it), but does what you asked for.
