Function: dired-do-redisplay

dired-do-redisplay is an autoloaded, interactive and byte-compiled function defined in dired-aux.el.gz.

Signature

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

Documentation

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 (dired-reset-subdir-switches). See Info node (emacs)Subdir switches for more details.
