  I love zsh [zsh.org]. It supports the korn shell globbing above as well as:
  
  % ls ^*.[ch]

BTW, you probably also want to be using comm(1) [freebsd.org] instead of fgrep.
comm -23 $set1 $set2

Also, you should probably add a line to delete those temp files:
trap "rm -f $set1 $set2" EXIT HUP INT QUITE TERM

That way, they get deleted on exit, or if some common signal gets delivered.
