I have tried finding such function in Dired and did not succeed, maybe it exists in Emacs programs somewhere. (defun rcd-dired-find-symlink () "Find target of a symlink" (interactive) (when (dired-get-marked-files) (let ((file (car (dired-get-marked-files)))) (if (file-symlink-p file) (let* ((file (file-truename file)) (directory (file-name-directory file)) (file (file-name-nondirectory file)) (back (length file))) (find-file directory) (search-forward file) (backward-char back)) (message "Not a symlink: %s" file))))) Let me know if I should improve this by any means.
