Comparing multiple files using diff

Comment:
I am comparing two files fine using diff as follows and manipulating the results: diff FileA FileB | sort -u > result How do I do the same for a sets of file some thing like this: comapare set of File A with File A' and File B with File B' and have the result onto a file. So, Looking for some thing: add the result of 'diff fileA fileA' with 'diff FileB FileB' and so on and sort and get unique records...
Should I use a pipe/cat ? Or an Array ? Note, I need to several sets comparison. So I am looking on efficiency.

I would put A, B... in directory1 and A', B'... in directory2 but with the same names used in directory1 (A, B...), then run "diff -u directory1 directory2".
Other interesting options for diff are -N for new files, -a for forcing ASCII, and -r for recursing subdirectories. For example, I use "diff -Nuar dir1 dir2" for Linux kernel trees.
