1879 Mode for \"editing\" directory listings.
1880 In Dired, you are \"editing\" a list of the files in a directory and
1881 (optionally) its subdirectories, in the format of `ls -lR'.
1882 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1883 \"Editing\" means that you can run shell commands on files, visit,
1884 compress, load or byte-compile them, change their file attributes
1885 and insert subdirectories into the same buffer. You can \"mark\"
1886 files for later commands or \"flag\" them for deletion, either file
1887 by file or all files matching certain criteria.
1888 You can move using the usual cursor motion commands.\\<dired-mode-map>
1889 The buffer is read-only. Digits are prefix arguments.
1890 Type \\[dired-flag-file-deletion] to flag a file `D' for deletion.
1891 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1892 Most commands operate on the marked files and use the current file
1893 if no files are marked. Use a numeric prefix argument to operate on
1894 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1895 to operate on the current file only. Prefix arguments override marks.
1896 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1897 to see why something went wrong.
1898 Type \\[dired-unmark] to Unmark a file or all files of an inserted subdirectory.
1899 Type \\[dired-unmark-backward] to back up one line and unmark or unflag.
1900 Type \\[dired-do-flagged-delete] to delete (eXecute) the files flagged `D'.
1901 Type \\[dired-find-file] to Find the current line's file
1902 (or dired it in another buffer, if it is a directory).
1903 Type \\[dired-find-file-other-window] to find file or Dired directory in Other window.
1904 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1905 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1906 Type \\[dired-do-copy] to Copy files.
1907 Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1908 Type \\[revert-buffer] to read all currently expanded directories aGain.
1909 This retains all marks and hides subdirs again that were hidden before.
1910 Use `SPC' and `DEL' to move down and up by lines.
1912 If Dired ever gets confused, you can either type \\[revert-buffer] \
1914 directories again, type \\[dired-do-redisplay] \
1915 to relist the file at point or the marked files or a
1916 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1917 again for the directory tree.

3994 If there is no `*', but there is a `?' in COMMAND, surrounded by

3998 Otherwise, this runs COMMAND on each file individually with the

4001 `*' and `?' when not surrounded by whitespace have no special
4002 significance for `dired-do-shell-command', and are passed through
4003 normally to the shell, but you must confirm first.
4005 If you want to use `*' as a shell wildcard with whitespace around

4007 `*' in the shell, but avoids Dired's special handling.

4013 However, when COMMAND ends in `;' or `;&' then commands are executed
4014 in the background on each file sequentially waiting for each command
4015 to terminate before running the next command. You can also use
4016 `dired-do-async-shell-command' that automatically adds `&'.
4018 Otherwise, COMMAND is executed synchronously, and the output
4019 appears in the buffer `*Shell Command Output*'.
