Single most useful example of using dired (Emacs)
dired, emacs
Solution
For me `wdired` is one of the nicest feature to be used with dired, it allows to do all sorts of emacs editing magic things on a directory to be able to rename the files, see some of the documentation on the emacswiki's page :

Problem
What is your single most useful example of using dired mode in Emacs? Any nice tricks? Please one example per answer.
