Nonzero CPU% in Linux

Question

I want to exclude processes with CPU=0.0 from result of ps aux command. Is it possible without any perversions (such as grep)?

Did you consider using `top` or `htop` ? – Basile Starynkevitch Nov 01 '14 at 14:43 — Basile Starynkevitch, Nov 01 '14 at 14:43

You could use awk:

ps aux | awk '{if ($3 != 0.0) print $0}'

This will include headers since the header is != "0.0"

If you're not familiar with the syntax, this awk command will test the third element in each line (split by " " space, by default) to see if it's not "0.0". If it isn't then it will print the entire line ($0).

ps aux | awk '$3!=0.0 {print}'

the third field that is cpu is not 0.0 will print the whole line

if you want cpu usage in descending order i.e high to low usage

ps aux --sort=-%cpu | awk '$3!=0.0 {print}'
