The following variables can be used to customize omitting.
nil, “uninteresting” files are not listed.
Uninteresting files are those whose files whose names match regexp
dired-omit-files, plus those ending with extensions in
dired-omit-extensions. C-x M-o (
toggles its value, which is buffer-local. Put
dired-mode-hook to have omitting initially turned on in
every Dired buffer (see Installation). You can then use
C-x M-o to unomit in that buffer.
To enable omitting automatically only in certain directories you can add a directory local setting (see Directory Variables in The Gnu Emacs manual) for Dired mode
((dired-mode . ((dired-omit-mode . t))))
to a .dir-locals.el file in that directory. You can use the
add-dir-local-variable to do this.
Files whose names match this buffer-local regexp will not be displayed.
This only has effect when
dired-omit-mode’s value is
The default value omits the special directories . and .. and autosave files (plus other files ending in .) (see Omitting Examples).
Default: The elements of
nil, a list of extensions (strings) to omit from Dired listings.
Its format is the same as that of
The localp argument
dired-omit-expunge passes to
dired-get-filename. If it is
no-dir, omitting is much faster,
but you can only match against the non-directory part of the file name. Set it
nil if you need to match the whole file name or
t to match the
file name relative to the buffer’s top-level directory.
Temporary marker used by Dired to implement omitting. Should never be used as marker by the user or other packages. There is one exception to this rule: by adding
(setq dired-mark-keys "\C-o") ;; i.e., the value of dired-omit-marker-char ;; (which is not defined yet)
to your ~/.emacs, you can bind the C-o key to insert a C-o marker, thus causing these files to be omitted in addition to the usually omitted files. Unfortunately the files you omitted manually this way will show up again after reverting the buffer, unlike the others.
