Thanx to you both... This is great KM education, I will surely attempt to put all this into practice.
I would though enjoy just a bit of clarification from Airy concerning this comment:
Please let me know if I am way off base. I presume that the ps -x refers to the terminal ps command. But here it is just text... or so I thought. How does this execute until action know that we are looking at the result of a terminal command?
