If your "Afiles" and "Bfiles" inputs are in sorted order, then the
"comm" utility can replace both of the diff calls above.  You'll get an
output showing what only exists in A, what exists in both, and what
only exists in B.

  man comm

for the man page or 

  info coreutils 'comm invocation'

if you want to read the "info" documentation.
