dired-do-redisplay

dired-do-redisplay is an interactive autoloaded compiled Lisp function in `dired-aux.el'.


(dired-do-redisplay &optional ARG TEST-FOR-SUBDIR)

Redisplay all marked (or next ARG) files.
If on a subdir line, redisplay that subdirectory. In that case,
a prefix arg lets you edit the `ls' switches used for the new listing.

Dired remembers switches specified with a prefix arg, so that reverting
the buffer will not reset them. However, using `dired-undo' to re-insert
or delete subdirectories can bypass this machinery. Hence, you sometimes
may have to reset some subdirectory switches after a `dired-undo'.
You can reset all subdirectory switches to the default using
M-x dired-reset-subdir-switches.
See Info node `(emacs)Subdir switches' for more details.
