29 ;; It is documented in the Emacs manual.
31 ;; Rewritten in 1990/1991 to add tree features, file marking and
32 ;; sorting by Sebastian Kremer <sk@thp.uni-koeln.de>.
33 ;; Finished up by rms in 1992.

58 "Switches passed to `ls' for Dired. MUST contain the `l' option.
59 May contain all other options that don't contradict `-l';
60 may contain even `F', `b', `i' and `s'. See also the variable
61 `dired-ls-F-marks-symlinks' concerning the `F' switch.
62 On systems such as MS-DOS and MS-Windows, which use `ls' emulation in Lisp,
63 some of the `ls' switches are not supported; see the doc string of
64 `insert-directory' in `ls-lisp.el' for more details."
69 "If non-nil, switches passed to `ls' for inserting subdirectories.
70 If nil, `dired-listing-switches' is used."
80 "Name of chown command (usually `chown')."
86 The special value of `unspecified' means to check explicitly, and
87 save the result in this variable. This is performed the first
88 time `dired-insert-directory' is called.
90 Note that if you set this option to nil, either through choice or
93 spaces. You might want to install ls from GNU Coreutils, which does
94 support this option. Alternatively, you might want to use Emacs's
96 (setq ls-lisp-use-insert-directory-program nil)
99 Note that `ls-lisp' does not support as many options as GNU ls, though.
100 For more details, see Info node `(emacs)ls in Lisp'."
107 "Name of chmod command (usually `chmod')."
112 "Name of touch command (usually `touch')."
117 "Informs Dired about how `ls -lF' marks symbolic links.
118 Set this to t if `ls' (or whatever program is specified by
119 `insert-directory-program') with `-lF' marks the symbolic link
120 itself with a trailing @ (usually the case under Ultrix).
122 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
123 nil (the default), if it gives `bar@ -> foo', set it to t.
125 Dired checks if there is really a @ appended. Thus, if you have a
126 marking `ls' program on one host and a non-marking on another host, and
127 don't care about symbolic links which really end in a @, you can
128 always set this variable to t."

143 "Controls marking of renamed files.
144 If t, files keep their previous marks when they are renamed.
145 If a character, renamed files (whether previously marked or not)
146 are afterward marked with that character.
147 This option affects only files renamed by `dired-do-rename' and
148 `dired-do-rename-regexp'. See `wdired-keep-marker-rename'
149 if you want to do the same for files renamed in WDired mode."
155 "Controls marking of copied files.
156 If t, copied files are marked if and as the corresponding original files were.
157 If a character, copied files are unconditionally marked with that character."
163 "Controls marking of newly made hard links.
164 If t, they are marked if and as the files linked to were marked.
165 If a character, new links are unconditionally marked with that character."
171 "Controls marking of newly made symbolic links.
172 If t, they are marked if and as the files linked to were marked.
173 If a character, new links are unconditionally marked with that character."
179 "If non-nil, Dired tries to guess a default target directory.
180 This means: if there is a Dired buffer displayed in the next
181 window, use its current directory, instead of this Dired buffer's
182 current directory.
184 The target is used in the prompt for file copy, rename etc."

218 "Hook run after each time a file or directory is read by Dired.
219 After each listing of a file or directory, this hook is run
220 with the buffer narrowed to the listing."

238 See `dnd-protocol-alist' for more information. When nil, behave
239 as in other buffers. Changing this option is effective only for
240 new Dired buffers."
247 "Non-nil means `dired-hide-details-mode' hides symbolic link targets."
253 "Non-nil means `dired-hide-details-mode' hides all but header and file lines."
259 "Non-nil means revert buffers visiting files before searching them.
260 By default, commands like `dired-mark-files-containing-regexp' will
261 search any buffers visiting the marked files without reverting them,
262 even if they were changed on disk. When this option is non-nil, such
263 buffers are always reverted in a temporary buffer before searching
264 them: the search is performed on the temporary buffer, the original
265 buffer visiting the file is not modified."
