Question: I am using cpufreq gnome extension and it give's me warning [irqbalance detected](https://i.stack.imgur.com/xjnKd.jpg). Is that something to worry about? And if I somehow stop irqbalance will that affect the processor?

Answer: 
If you want the second field of the last line using that field separator:

```
awk -F"[()]" 'END {print $2}' /home/jj1/.pia_manager/log/pia_nw.log

```
Pipe the output of the first awk to the second awk:

```
awk 'END{print}' /home/jj1/.pia_manager/log/pia_nw.log | awk -F"[()]" '{print $2}'

```

This variant is more safe (ignore last empty lines in file):

```
awk '/^$/ {nlstack=nlstack "\n";next;} END{printf "%s",nlstack; nlstack=""; print;}' /home/jj1/.pia_manager/log/pia_nw.log | awk -F"[()]" '{print $2}'

```
