ipython shell awk : Escaping "$" sign

I am figuring out the Ipython shell support. Its seems awk doesn't work i.e following command

!ls -l | awk '{print $1}'

just prints "1".

How do I pass the "$" sign correctly to shell. I am using zsh.

Two dollar signs give you a literal dollar sign, so try:

!ls -l | awk '{print $$1}'

Try escaping $ as \$

!ls -l | awk '{print \$1}'
