If you want to find out which applications you run eat the most of your CPU, run the command below:
ps -eo pcpu,pid,args | sort -k 1 -r | head -10
This will display a top 10 list of those processes, starting with the hungriest at the top.
Linux – Top 10 CPU-hungry apps
Or you can just run
top
Simpler than all that pipelining, don’t you think?
@Visionplanet: of course it’s simpler. But try using top’s output in a script…
# top -n 1 >> /tmp/top.log
but of coz the command are easier to store information into log file
