59 "Switches passed to `ls' for Dired. MUST contain the `l' option.
60 May contain all other options that don't contradict `-l';
61 may contain even `F', `b', `i' and `s'. See also the variable
62 `dired-ls-F-marks-symlinks' concerning the `F' switch.
63 Options that include embedded whitespace must be quoted
65 `combine-and-quote-strings' to produce the correct quoting of
66 each option.
67 On systems such as MS-DOS and MS-Windows, which use `ls' emulation in Lisp,
68 some of the `ls' switches are not supported; see the doc string of
69 `insert-directory' in `ls-lisp.el' for more details."
74 "If non-nil, switches passed to `ls' for inserting subdirectories.
75 If nil, `dired-listing-switches' is used."
85 "Name of chown command (usually `chown')."
91 The special value of `unspecified' means to check explicitly, and
92 save the result in this variable. This is performed the first
93 time `dired-insert-directory' is called.
95 Note that if you set this option to nil, either through choice or
98 spaces. You might want to install ls from GNU Coreutils, which does
99 support this option. Alternatively, you might want to use Emacs's
101 (setq ls-lisp-use-insert-directory-program nil)
104 Note that `ls-lisp' does not support as many options as GNU ls, though.
105 For more details, see Info node `(emacs)ls in Lisp'."
112 "Name of chmod command (usually `chmod')."
117 "Name of touch command (usually `touch')."
122 "Informs Dired about how `ls -lF' marks symbolic links.
123 Set this to t if `ls' (or whatever program is specified by
124 `insert-directory-program') with `-lF' marks the symbolic link
125 itself with a trailing @ (usually the case under Ultrix).
127 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
128 nil (the default), if it gives `bar@ -> foo', set it to t.
130 Dired checks if there is really a @ appended. Thus, if you have a
131 marking `ls' program on one host and a non-marking on another host, and
132 don't care about symbolic links which really end in a @, you can
133 always set this variable to t."

151 are afterward marked with that character.
152 This option affects only files renamed by `dired-do-rename' and
153 `dired-do-rename-regexp'. See `wdired-keep-marker-rename'
154 if you want to do the same for files renamed in WDired mode."
160 "Controls marking of copied files.
161 If t, copied files are marked if and as the corresponding original files were.
162 If a character, copied files are unconditionally marked with that character."

184 "If non-nil, Dired tries to guess a default target directory.
185 This means: if there is a Dired buffer displayed in the next
186 window, use its current directory, instead of this Dired buffer's
187 current directory.

246 as in other buffers. Changing this option is effective only for
247 new Dired buffers."
254 "Non-nil means `dired-hide-details-mode' hides symbolic link targets."
260 "Non-nil means `dired-hide-details-mode' hides all but header and file lines."
266 "Non-nil means revert buffers visiting files before searching them.
267 By default, commands like `dired-mark-files-containing-regexp' will
268 search any buffers visiting the marked files without reverting them,
269 even if they were changed on disk. When this option is non-nil, such
270 buffers are always reverted in a temporary buffer before searching
271 them: the search is performed on the temporary buffer, the original
272 buffer visiting the file is not modified."
