How can I delete the current line in Emacs?

Question

What is the emacs equivalent of vi\'s dd? I want to delete the current line. Tried CTRL + k but it only deletes from current position.

In case you don't want to kill the line (which would put it into the OS clipboard and kill ring) but simply delete it:

(defun delete-current-line ()
  "Delete (not kill) the current line."
  (interactive)
  (save-excursion
    (delete-region
     (progn (forward-visible-line 0) (point))
     (progn (forward-visible-line 1) (point)))))
