I can't obtain CPU% usage of all the pid, without know any program names.

I feel I am close to the solution, this is what I've done so far:

```
for line in $(pgrep -f chrome); \
   do echo -n $line" - ";       \ 
   ps -p $line -o %cpu | sed -n 2p | sed 's/ //'; done

```

In this example I obtain only all chrome pid.. in next step I want all executing pid.
