Hi,

Anyone know a command-line tool (or tools piped together) that
could achieve the following results.  Given...

% cat fileA
  line1
  line2
  line3

% cat fileB
  line2
  line4
  line5

% cat fileC
  line1
  line4
  line6
  line7

I would like to see all the lines in fileC that are not in fileA or
fileB.  In my case, I may be seraching against many files, i.e., 
(A,B,C,etc...)

So my desired result would be:

  line6
  line7

Doug
