Introduction

Aside from editing files, including local and remote ones, Emacs can also play the role of a file manager, i.e., manipulating directories and the files by its directory editor, dired.

Enter dired buffer

Dired can be entered in following ways:

Command: M-x dired
Key bindings
- C-x d is equivalent to the command above.
- C-x 4 d open a dired buffer in another window.

Navigation

`^`	Go up one directory
`n/C-n`	Move the point down an entry
`p/C-p`	Move the point up an entry
`q`	Quit dired

Marking & unmarking

Marking and unmarking enable operations on multiple files or directories.

`u`	Unmark the active entry or the selected region
`U`	Unmark everything
`d`	Flag for deletion
`t`	Toggle existing marking
`* %`	Mark files and directories by regexp
`* c`	Change marks
`~`	Mark backup files

Operations

Key	Description

`v`	View the file/directory in read-only mode
`g`	Refresh dired buffer
`+`	Create a directory
`C`	Copy marked files/directories
`R`	Rename/move marked files/directories
`O`	Perform `chown` on marked files/directories

`M`	Perform `chmod` on marked files/directories
`D`	Delete marked files/directories
`x`	Delete flagged (marked by `d`) files/directories

Working across directories

In dired buffer, typing i on a directory will insert it in the same dired buffer as a sub-directory.

By inserting multiple directories into a shared dired buffer, you can not only glance at multiple directories simultaneously but you can also work across them as if they were one large virtual directory.
