28 ;; The parts of dired mode not normally used. This is a space-saving hack
29 ;; to avoid having to load a large mode when all that's wanted are a few
30 ;; functions.
32 ;; Rewritten in 1990/1991 to add tree features, file marking and
33 ;; sorting by Sebastian Kremer <sk@thp.uni-koeln.de>.
34 ;; Finished up by rms in 1992.
36 ;;; Code:
38 ;; We need macros in dired.el to compile properly,
39 ;; and we call subroutines in it too.

612 If no files are marked or a numeric prefix arg is given,
614 The prompt mentions the file(s) or the marker, as appropriate.
616 If there is a `*' in COMMAND, surrounded by whitespace, this runs
617 COMMAND just once with the entire file list substituted there.
619 If there is no `*', but there is a `?' in COMMAND, surrounded by
620 whitespace, this runs COMMAND on each file individually with the
621 file name substituted for `?'.
623 Otherwise, this runs COMMAND on each file individually with the
624 file name added at the end of COMMAND (separated by a space).
626 `*' and `?' when not surrounded by whitespace have no special
627 significance for `dired-do-shell-command', and are passed through
628 normally to the shell, but you must confirm first.
630 If you want to use `*' as a shell wildcard with whitespace around
632 `*' in the shell, but avoids Dired's special handling.
634 If COMMAND ends in `&', `;', or `;&', it is executed in the
635 background asynchronously, and the output appears in the buffer
636 `*Async Shell Command*'. When operating on multiple files and COMMAND
637 ends in `&', the shell command is executed on each file in parallel.

639 in the background on each file sequentially waiting for each command
640 to terminate before running the next command. You can also use
641 `dired-do-async-shell-command' that automatically adds `&'.
643 Otherwise, COMMAND is executed synchronously, and the output
644 appears in the buffer `*Shell Command Output*'.
646 This feature does not try to redisplay Dired buffers afterward, as
647 there's no telling what files COMMAND may have changed.
650 When COMMAND runs, its working directory is the top-level directory
651 of the Dired buffer, so output files usually are created there
