Wasn't the problem how to find the right, in this case, "target.txt" in a situation like this: /home/incal/test/dired: lrwxrwxrwx 1 incal 10 May 23 22:41 target-link.txt -> target.txt -rw-r--r-- 1 incal 0 May 23 22:41 target.txt Search for "target.txt". When you find it, use (get-text-property (point) 'dired-filename) Here it is nil: lrwxrwxrwx 1 incal 10 May 23 22:41 target-link.txt -> target.txt ^ So search again, here it is t: -rw-r--r-- 1 incal 0 May 23 22:41 target.txt ^ and that's the target you are looking for. -- underground experts united https://dataswamp.org/~incal
