Hi together, after I read "very often" without even a tiny bit of a contradiction, I start to have the feeling I have a basic misunderstanding of rsync. Assume one want to get a list of files which would have been transfered by rsync if rsync was requested to sync directories X and Y and one does <code> X=`mktemp` echo "abc" > $X/1 echo "abc1" > $X/2
