  I ended up with this in my .bashrc so I didn't have to keep remembering how to use comm each time:

    justA()  { comm -23 <(sort -u "$1") <(sort -u "$2"); }
    justB()  { comm -13 <(sort -u "$1") <(sort -u "$2"); }
    bothAB() { comm -12 <(sort -u "$1") <(sort -u "$2"); }

  Cool, can't believe I didn't know about comm command. I usually like to use sets() for this type of thing with python or ruby it is easy.

  Or just:

      vim -d file1 file2
      :%!sort | uniq -c
      :wincmd l
      :%!sort | uniq -c
