   This is not always so safe, because not all users understand the 
implications of a 1 character difference between two command lines, one being 
safe, the other being devastating.  It is also possible to write the command 
in such a confusing manner as to make it unclear what the command is that's 
being executed as displayed in the messagebox.  Don't rely on this too
