I figured that you were referring to something like that.  But I wanted 
to ask in case there was something else that I didn't know about but 
could benefit from knowing.  I.e. vimscript.

Nice global command.  Run the substitution (globally on the line) on any 
line containing "unix".  I like it.  ;-)

The double << is different than what I would expect.  I wonder if that's 
specific to the shell or appending to the input after the file?

That makes sense.  Thank you for the explanation.
