Emacs: Dired Sort File by Time, Size

By Xah Lee. Date: . Last updated: .

Here's a emacs command that lets you sort dired file listing by any {date/time, size, name}.

put this in your Emacs Init File:

(defun xah-dired-sort ()
  "Sort dired dir listing in different ways.
Prompt for a choice.

  (interactive)
  (let (xsortBy xarg)
    (setq xsortBy (completing-read "Sort by:" '( "date" "size" "name" )))
    (cond
     ((equal xsortBy "name") (setq xarg "-Al "))
     ((equal xsortBy "date") (setq xarg "-Al -t"))
     ((equal xsortBy "size") (setq xarg "-Al -S"))
     ((equal xsortBy "dir") (setq xarg "-Al --group-directories-first"))
     (t (error "logic error 09535" )))
    (dired-sort-other xarg )))

Works in linux, MacOS, Microsoft Windows.

Give it a keybinding for easy call.

(require 'dired )
(define-key dired-mode-map (kbd "s") 'xah-dired-sort)
