Adding Disk Usage Reporting to Emacs Dired
Just a quick one today. One of the great strengths of Emacs is its extensibility, I have mentioned before in adding the ability to disk report on the size of a directory in dired
but I thought I would quickly revisit the topic, demonstrating the function I currently use.
This functionality will allow you to run disk usage reports directly within Dired, using the du -hc
command. This will make it easier to figure out how much space directories are taking up.
The aim of this function is to run the Linux command du -hc
on the directory currently under the cursor in Dired mode. The command du -hc
provides a human-readable summary of disk usage for the specified directory.
Here’s the function that accomplishes this task:
(defun my/dired-du ()
"Run 'du -hc' on the directory under the cursor in Dired."
(interactive)
(let ((current-dir (dired-get-file-for-visit)))
(if (file-directory-p current-dir)
(dired-do-async-shell-command "du -hc" nil (list current-dir))
(message "The current point is not a directory."))))
and that is it!
