[sclug] Suppressing variable subsititution in a bash script

[Tim Sutton]

I am trying to do the following in a bash script:

for PID in `ps -ef |grep "java -Djava.security.policy" |awk '{$2}'`;
do
	....
done

Which is not working - I suspect because the $2 in awk'{$2}' is being expanded 
out? How do I suppress this? I tried \$2 but that does not seem to work?

Thanks 

Tim
