Emacs: File Manager, dired
Emacs is a excellent tool for file management. For example, list files, copy/delete, rename, moving files, create/delete directory. Once you become familiar with it, you almost never go to shell or the Operating System file manager for these tasks.
“dired” is short for Directory Edit. It is a old term for file management.
To start viewing directory, Alt+x
When in dired, most commands have a single letter key.
Here's the most useful commands:
- Open the file or directory.
- hide the dired buffer. (when you are done) Display last buffer.
- Copy file
- Rename/move file
- Delete file or directory
- Create new dir
- Compress/decompress the file by gzip
Tip: you can have copy command automatically select the target dir in a split pane.
(setq dired-dwim-target t).
