This file defines a minor mode dired-du-mode to show the recursive size of directories in Dired buffers. If du program is available, then the directory sizes are obtained with it. Otherwise, the directory sizes are obtained with Lisp. The former is much faster. For directories where the user doesn't have read permission, the recursive size is not obtained.
Once this mode is enabled, every new Dired buffer displays recursive dir sizes.
To enable the mode at start up:
- Store the file in a directory within load-path.
- Add the following into .emacs file:
(add-hook 'dired-mode-hook #'dired-du-mode)
Note that obtaining the recursive size of all the directories in a Dired buffer might be very slow: it may significantly delay the time to display a new Dired buffer. Instead of enabling dired-du-mode by default in all Dired buffers you might prefer to use this mode as an interfaz to the du program: you can enable it in the current Dired buffer, and disable it once you have finished checking the used space.
In adition, this library adds a command, dired-du-count-sizes, to count the number of marked files and how much space they use; the command accepts a particular character mark i.e., '*' or all kind of marks i.e, any character other than ?\s.
