Dired tips

(Alphabetical order)

Ctrl x Ctrl f	Visiting (opening) files. (This puts us in Emac’s dired mode - directory editor). To create a new file, just start typing the name of the file that you want to create.
g	Refresh the listing in dired mode
m	mark a file in dired mode
u	un-mark a file in dired mode
U	un-mark all files
w	When you are in dired mode, if you put the point on a file and press w, the name of the file will be copied into the kill ring. Makes it easier if you are trying to rename files.
Ctrl x Ctrl q	Turn dired into editing mode. You can then edit the file names by hand or use M-% to replace foo with bar in the dired buffer. This will change the file names. Use C-c C-c so apply the changes, or C-c ESC to cancel
d	Flag this file for deletion (dired-flag-file-deletion).
C	copy a file
R	rename/move a file
D	delete a file
u	Remove the deletion flag (dired-unmark).
x	Delete files flagged for deletion (dired-do-flagged-delete).

Supposing you wanted to delete a bunch of files, but wanted to see them first to visually check you are deleting the right ones, you might do the following:

1. mark the files manually, or using a regular expression
2. * t invert the selection
3. k hide the selected files so now you see the ones you originally selected for deletion so you can check you got the right ones
4. * s to select those visible files
5. D to delete them
