rsync filter based on an intermediate directory name

Question

I want to copy files /SRC/**/OK/**/*OK* to /DEST/**/OK/**/*OK* using rsync.

For all the files to copy, there must be a folder named OK in the full path and a OK in the filename.

I tried

rsync -avP --include='**/OK/**/*OK*' --include='*/' --exclude='*' --inplace SRC DEST

It doesn't work.

rsync -avP --include='*OK*' --include='*/' --exclude='*' --inplace SRC DEST

works but it creates all the folders, no matter whether they contain OK in the full path or not.

Answer 1

rsync -am --include='**/OK/**/*OK*' --include='*/' --exclude='*' --delete-excluded SRS DEST

Try this one. -m deletes "empty" directories that were created while traversing SRS sub directories, and --delete-excluded to make rsync not look like cp.
