I’ve written before about using the editing features in dired (AKA wdired) to do neat things likeredirect symlinks. I recently discovered that by adding the following option to youremacs config file:

;; allow editing file permissions (setq wdired-allow-to-change-permissions t)

then you can also edit the file permissions directly in the dired buffer.

Here’s a quick animated example where I want to set group write permissions for all the pdf files in a particular directory. I use several tools to make this really easy:

I useddired-narrow to filter the view down to just the pdf files I use C-x C-q to make the dired buffer editable I move to the group write permission spot on the first line and then usemultiple cursors to add a cursor for each line I hit w to set the write permission, RET to quit multiple cursors, and C-c C-c to make the change permanent
