1839 Mode for \"editing\" directory listings.
1840 In Dired, you are \"editing\" a list of the files in a directory and
1841   \(optionally) its subdirectories, in the format of `ls -lR'.
1842   Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1843 \"Editing\" means that you can run shell commands on files, visit,
1844   compress, load or byte-compile them, change their file attributes
1845   and insert subdirectories into the same buffer.  You can \"mark\"
1846   files for later commands or \"flag\" them for deletion, either file
1847   by file or all files matching certain criteria.
1848 You can move using the usual cursor motion commands.\\<dired-mode-map>
1849 The buffer is read-only.  Digits are prefix arguments.
1850 Type \\[dired-flag-file-deletion] to flag a file `D' for deletion.
1851 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1852   Most commands operate on the marked files and use the current file
1853   if no files are marked.  Use a numeric prefix argument to operate on
1854   the next ARG (or previous -ARG if ARG<0) files, or just `1'
1855   to operate on the current file only.  Prefix arguments override marks.
1856   Mark-using commands display a list of failures afterwards.  Type \\[dired-summary]
1857   to see why something went wrong.
1858 Type \\[dired-unmark] to Unmark a file or all files of an inserted subdirectory.
1859 Type \\[dired-unmark-backward] to back up one line and unmark or unflag.
1860 Type \\[dired-do-flagged-delete] to delete (eXecute) the files flagged `D'.
1861 Type \\[dired-find-file] to Find the current line's file
1862   (or dired it in another buffer, if it is a directory).
1863 Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1864 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1865 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1866 Type \\[dired-do-copy] to Copy files.
1867 Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1868 Type \\[revert-buffer] to read all currently expanded directories aGain.
1869   This retains all marks and hides subdirs again that were hidden before.
1870 Use `SPC' and `DEL' to move down and up by lines.
1871
1872 If Dired ever gets confused, you can either type \\[revert-buffer] \
1873 to read the
1874 directories again, type \\[dired-do-redisplay] \
1875 to relist the file at point or the marked files or a
1876 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1877 again for the directory tree.

3905
3906 If there is a `*' in COMMAND, surrounded by whitespace, this runs
3907 COMMAND just once with the entire file list substituted there.
3908
3909 If there is no `*', but there is a `?' in COMMAND, surrounded by
3910 whitespace, this runs COMMAND on each file individually with the
3911 file name substituted for `?'.
3912
3913 Otherwise, this runs COMMAND on each file individually with the
3914 file name added at the end of COMMAND (separated by a space).
3915
3916 `*' and `?' when not surrounded by whitespace have no special
3917 significance for `dired-do-shell-command', and are passed through
3918 normally to the shell, but you must confirm first.
3919
3920 If you want to use `*' as a shell wildcard with whitespace around
3921 it, write `*\"\"' in place of just `*'.  This is equivalent to just
3922 `*' in the shell, but avoids Dired's special handling.
3923
3924 If COMMAND ends in `&', `;', or `;&', it is executed in the
3925 background asynchronously, and the output appears in the buffer
3926 `*Async Shell Command*'.  When operating on multiple files and COMMAND
3927 ends in `&', the shell command is executed on each file in parallel.
3928 However, when COMMAND ends in `;' or `;&' then commands are executed
3929 in the background on each file sequentially waiting for each command
3930 to terminate before running the next command.  You can also use
3931 `dired-do-async-shell-command' that automatically adds `&'.
3932
3933 Otherwise, COMMAND is executed synchronously, and the output
3934 appears in the buffer `*Shell Command Output*'.

3940 When COMMAND runs, its working directory is the top-level directory
3941 of the Dired buffer, so output files usually are created there
3942 instead of in a subdir.

3944 In a noninteractive call (from Lisp code), you must specify
