[kepler-users] runing complex command in external execution actor

    I am not sure why the one command fails and the other works, but the 
command line actor is known to not work quite like the actual  command 
line at times. It is also dependent on the OS. Are you on linux? I would 
suggest trying to put the command into a shell script. I will file a bug 
on this and hopefully we can get some time to figure out the problem.
