Actually, it's no problem having any of those characters in your arguments,

My point is that using 'words' on the argument sting to 'runProcess' and expecting the same result as 'runCommand' implies making those assumptions::

My point was that which of these is correct entirely depends on what your input is. It's often a huge (and security-bug-prone) chore to escape all those shell characters, and so in many cases it's much nicer to execute an external program direcly without invoking a shell. David
