Emacs Dired Mode

Dired stands for Directory Editor and the dired buffer lists the folder's child files (and child folders.

Dired Mode | Why Omit Dot Prefixed Content

Your productivity rises when you omit files and folders whose names begin with a period (dot). These items are not for everyday consumption and looking through a long list of dot prefixed files, slows you down.

Dired Mode | Omit Dot Prefixed Content

The simplest way to omit these files and folders in every Dired buffer is to add some directives into the .emas file that lives off your home directory.

Don't worry if no .emacs file exists - just create it.

Now add (or append) these directives into .emacs.

   (require 'dired-x)
    (setq-default dired-omit-files-p t) ; Buffer-local variable
    (setq dired-omit-files (concat dired-omit-files "\\|^\\..+$"))

Then restart emacs and you'll see the effect.

Dired Mode | Omit Squiggle Terminated Files

The above omit mode also hides files with a trailing squiggle - these are the ubiquitous emacs backup files.

If checking content into Git - you can either .gitignore the squiggle files or tell emacs not to create them in the first place (I'm a big boy (or girl) - I know what I'm doing).
