Note that if you set this option to nil, either through choice or

will fail to parse some \"unusual\" file names, e.g. those with leading
spaces. You might want to install ls from GNU Coreutils, which does
support this option. Alternatively, you might want to use Emacs's
own emulation of \"ls\", by using:
\(setq ls-lisp-use-insert-directory-program nil)
\(require 'ls-lisp)

Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to

Dired checks if there is really a @ appended. Thus, if you have a

"\
Mode for \"editing\" directory listings.
In Dired, you are \"editing\" a list of the files in a directory and
\(optionally) its subdirectories, in the format of `ls -lR'.
Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
\"Editing\" means that you can run shell commands on files, visit,
compress, load or byte-compile them, change their file attributes
and insert subdirectories into the same buffer. You can \"mark\"
files for later commands or \"flag\" them for deletion, either file
by file or all files matching certain criteria.
You can move using the usual cursor motion commands.\\<dired-mode-map>
The buffer is read-only. Digits are prefix arguments.
Type \\[dired-flag-file-deletion] to flag a file `D' for deletion.
Type \\[dired-mark] to Mark a file or subdirectory for later commands.
Most commands operate on the marked files and use the current file
if no files are marked. Use a numeric prefix argument to operate on
the next ARG (or previous -ARG if ARG<0) files, or just `1'
to operate on the current file only. Prefix arguments override marks.
Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
to see why something went wrong.
Type \\[dired-unmark] to Unmark a file or all files of an inserted subdirectory.
Type \\[dired-unmark-backward] to back up one line and unmark or unflag.
Type \\[dired-do-flagged-delete] to delete (eXecute) the files flagged `D'.
Type \\[dired-find-file] to Find the current line's file
(or dired it in another buffer, if it is a directory).
Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
Type \\[dired-do-copy] to Copy files.
Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
Type \\[revert-buffer] to read all currently expanded directories aGain.
This retains all marks and hides subdirs again that were hidden before.
Use `SPC' and `DEL' to move down and up by lines.
If Dired ever gets confused, you can either type \\[revert-buffer] \
to read the
directories again, type \\[dired-do-redisplay] \
to relist the file at point or the marked files or a
subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
again for the directory tree.

(autoload 'dired-do-async-shell-command "dired-aux" "\
Run a shell command COMMAND on the marked files asynchronously.
Like `dired-do-shell-command', but adds `&' at the end of COMMAND
to execute it asynchronously.
When operating on multiple files, asynchronous commands
are executed in the background on each file in parallel.
In shell syntax this means separating the individual commands
with `&'. However, when COMMAND ends in `;' or `;&' then commands
are executed in the background on each file sequentially waiting
for each command to terminate before running the next command.
In shell syntax this means separating the individual commands with `;'.
The output appears in the buffer `*Async Shell Command*'.
\(fn COMMAND &optional ARG FILE-LIST)" t nil)
(autoload 'dired-do-shell-command "dired-aux" "\
Run a shell command COMMAND on the marked files.
If no files are marked or a numeric prefix arg is given,
the next ARG files are used. Just \\[universal-argument] means the current file.
The prompt mentions the file(s) or the marker, as appropriate.
If there is a `*' in COMMAND, surrounded by whitespace, this runs
COMMAND just once with the entire file list substituted there.
If there is no `*', but there is a `?' in COMMAND, surrounded by
whitespace, this runs COMMAND on each file individually with the
file name substituted for `?'.
Otherwise, this runs COMMAND on each file individually with the
file name added at the end of COMMAND (separated by a space).
`*' and `?' when not surrounded by whitespace have no special
significance for `dired-do-shell-command', and are passed through
normally to the shell, but you must confirm first.
If you want to use `*' as a shell wildcard with whitespace around
it, write `*\"\"' in place of just `*'. This is equivalent to just
`*' in the shell, but avoids Dired's special handling.
If COMMAND ends in `&', `;', or `;&', it is executed in the
background asynchronously, and the output appears in the buffer
`*Async Shell Command*'. When operating on multiple files and COMMAND
ends in `&', the shell command is executed on each file in parallel.
However, when COMMAND ends in `;' or `;&' then commands are executed
in the background on each file sequentially waiting for each command
to terminate before running the next command. You can also use
`dired-do-async-shell-command' that automatically adds `&'.
Otherwise, COMMAND is executed synchronously, and the output
appears in the buffer `*Shell Command Output*'.
This feature does not try to redisplay Dired buffers afterward, as
there's no telling what files COMMAND may have changed.
Type \\[dired-do-redisplay] to redisplay the marked files.
When COMMAND runs, its working directory is the top-level directory
of the Dired buffer, so output files usually are created there
instead of in a subdir.
In a noninteractive call (from Lisp code), you must specify
the list of file names explicitly with the FILE-LIST argument, which
can be produced by `dired-get-marked-files', for example.
