chomp
  ...
  It returns the total number of characters removed from all its
  arguments.  It's often used to remove the newline from the end
  of an input record when you're worried that the final record
  may be missing its newline. When in paragraph mode ("$/ =
  """), it removes all trailing newlines from the string. When
  in slurp mode ("$/ = undef") or fixed-length record mode ($/
  is a reference to an integer or the like; see perlvar) chomp()
  won't remove anything.

So ... 

perl -e '$/ = "" ; $a = qq(AA\n\n); $b = qq(BB\n\n); $res = chomp ($a,
+$b); print qq(>$a< removed $res\n>$b< removed $res\n)'
>AA< removed 4
>BB< removed 4
