This section describes commands to update the Dired buffer to reflect outside (non-Dired) changes in the directories and files, and to delete part of the Dired buffer.

dired-do-kill-lines).
dired-sort-toggle-or-edit).
dired-listing-switches.
Type g (revert-buffer) to update the contents of the
Dired buffer, based on changes in the files and directories listed.
This preserves all marks except for those on files that have vanished.
Hidden subdirectories are updated but remain hidden.
To update only some of the files, type l
(dired-do-redisplay). This command applies to the next n
files, or to the marked files if any, or to the current file. Updating
them means reading their current status from the file system and
changing the buffer to reflect it properly.
If you use l on a subdirectory header line, it updates the contents of the corresponding subdirectory.
To delete the specified file lines---not the files, just the
lines--type k (dired-do-kill-lines). With a numeric
argument n, this command applies to the next n files;
otherwise, it applies to the marked files.
If you kill the line for a file that is a directory, the directory's contents are also deleted from the buffer. Typing C-u k on the header line for a subdirectory is another way to delete a subdirectory from the Dired buffer.
The g command brings back any individual lines that you have killed in this way, but not subdirectories--you must use i to reinsert each subdirectory.
The files in a Dired buffers are normally listed in alphabetical order
by file names. Alternatively Dired can sort them by date/time. The
Dired command s (dired-sort-toggle-or-edit) switches
between these two sorting modes. The mode line in a Dired buffer
indicates which way it is currently sorted--by name, or by date.
C-u s switches RET lets you specify a new value for
dired-listing-switches.
