[kepler-users] using $ character in external execution actor

[Derik Barseghian]

Hi Ufuk,

Try escaping your $ with another $, ie $$2

I set up a test workflow, where one external execution actor ran the  
command: echo Hello world
I sent this output to the input of a second external execution actor  
that ran: awk "{print $$2}"
and received as output: world
