Hi,

Do you have some reason why -f (forced) parameter works ok if destionation where link point is a file, then it could update link by using forced mode.

If destionation where link point is folder then -f parameter not update link in this situation.

As you could see link still point to "EKA_DIR"… it should point to "TOKA_DIR" because there was -f parameter defined in ln command.
