1844 Mode for \"editing\" directory listings.
1845 In Dired, you are \"editing\" a list of the files in a directory and
1846 \(optionally) its subdirectories, in the format of `ls -lR'.
1847 Each directory is a page: use \\[backward-page] and \\[forward-page] to move pagewise.
1848 \"Editing\" means that you can run shell commands on files, visit,
1849 compress, load or byte-compile them, change their file attributes
1850 and insert subdirectories into the same buffer. You can \"mark\"
1851 files for later commands or \"flag\" them for deletion, either file
1852 by file or all files matching certain criteria.
1853 You can move using the usual cursor motion commands.\\<dired-mode-map>
1854 The buffer is read-only. Digits are prefix arguments.
1855 Type \\[dired-flag-file-deletion] to flag a file `D' for deletion.
1856 Type \\[dired-mark] to Mark a file or subdirectory for later commands.
1857 Most commands operate on the marked files and use the current file
1858 if no files are marked. Use a numeric prefix argument to operate on
1859 the next ARG (or previous -ARG if ARG<0) files, or just `1'
1860 to operate on the current file only. Prefix arguments override marks.
1861 Mark-using commands display a list of failures afterwards. Type \\[dired-summary]
1862 to see why something went wrong.
1863 Type \\[dired-unmark] to Unmark a file or all files of an inserted subdirectory.
1864 Type \\[dired-unmark-backward] to back up one line and unmark or unflag.
1865 Type \\[dired-do-flagged-delete] to delete (eXecute) the files flagged `D'.
1866 Type \\[dired-find-file] to Find the current line's file
1867 (or dired it in another buffer, if it is a directory).
1868 Type \\[dired-find-file-other-window] to find file or dired directory in Other window.
1869 Type \\[dired-maybe-insert-subdir] to Insert a subdirectory in this buffer.
1870 Type \\[dired-do-rename] to Rename a file or move the marked files to another directory.
1871 Type \\[dired-do-copy] to Copy files.
1872 Type \\[dired-sort-toggle-or-edit] to toggle Sorting by name/date or change the `ls' switches.
1873 Type \\[revert-buffer] to read all currently expanded directories aGain.
1874 This retains all marks and hides subdirs again that were hidden before.
1875 Use `SPC' and `DEL' to move down and up by lines.
1877 If Dired ever gets confused, you can either type \\[revert-buffer] \
1879 directories again, type \\[dired-do-redisplay] \
1880 to relist the file at point or the marked files or a
1881 subdirectory, or type \\[dired-build-subdir-alist] to parse the buffer
1882 again for the directory tree.

3927 If there is no `*', but there is a `?' in COMMAND, surrounded by

3934 `*' and `?' when not surrounded by whitespace have no special

3938 If you want to use `*' as a shell wildcard with whitespace around
