Hey Matt,
Relative --*-dest paths are interpreted relative to the destination
directory (as stated in the man page), so you should use:
rsync -av --compare-dest=../b a/ c/
tried that too, same result for me:
mkdir a b c
echo foo > a/test
echo foo > b/test
rsync -av --compare-dest=../b a/ c/
expected: no copy
actual result: a/test gets copied to c/test
(also tested with --compare-dest=../b/ --compare-test=/b/, and the other
things I actually tried I'm to emberrassed to write here :) )
Bye, Lucas
