Dired (quick file management in emacs)

Dired is a built-in file manager for Emacs that does some pretty amazing things! Here are some key bindings you should try out:

Key Bindings

Navigation

Emacs / Evil

• n / j - next line
• p / k - previous line
• j / J - jump to file in buffer
• RET - select file or directory
• ^ - go to parent directory
• S-RET / g O - Open file in "other" window
• M-RET - Show file in other window without focusing (previewing files)
• g o (dired-view-file) - Open file but in a "preview" mode, close with q
• g / g r Refresh the buffer with revert-buffer after changing configuration (and after filesystem changes!)

Marking files

• m - Marks a file
• u - Unmarks a file
• U - Unmarks all files in buffer
• * t / t - Inverts marked files in buffer
• % m - Mark files in buffer using regular expression
• * - Lots of other auto-marking functions
• k / K - "Kill" marked items (refresh buffer with g / g r to get them back)
• Many operations can be done on a single file if there are no active marks!

Copying and Renaming files

• C - Copy marked files (or if no files are marked, the current file)
• Copying single and multiple files
• U - Unmark all files in buffer
• R - Rename marked files, renaming multiple is a move!
• % R - Rename based on regular expression: ^test , old-\&

Power command: C-x C-q (dired-toggle-read-only) - Makes all file names in the buffer editable directly to rename them! Press Z Z to confirm renaming or Z Q to abort.

Deleting files

• D - Delete marked file
• d - Mark file for deletion
• x - Execute deletion for marks
• delete-by-moving-to-trash - Move to trash instead of deleting permanently

Creating and extracting archives

• Z - Compress or uncompress a file or folder to (.tar.gz)
• c - Compress selection to a specific file
• dired-compress-files-alist - Bind compression commands to file extension

Other common operations

• T - Touch (change timestamp)
• M - Change file mode
• O - Change file owner
• G - Change file group
• S - Create a symbolic link to this file
• L - Load an Emacs Lisp file into Emacs

Configuration

    (use-package dired
    :ensure nil
    :commands (dired dired-jump)
    :bind (("C-x C-j" . dired-jump))

  ;;   :config
  ;;   (evil-collection-define-key 'normal 'dired-mode-map
  ;;     "H" 'dired-hide-dotfiles-mode))

Folder Cleaning

  ;; NOTE: If you want to move everything out of the ~/.emacs.d folder
  ;; reliably, set `user-emacs-directory` before loading no-littering!
  ;(setq user-emacs-directory "~/.cache/emacs")

  (use-package no-littering
