625 "Run a shell command COMMAND on the marked files.
626 If no files are marked or a numeric prefix arg is given,
627 the next ARG files are used. Just \\[universal-argument] means the current file.
628 The prompt mentions the file(s) or the marker, as appropriate.
630 If there is a `*' in COMMAND, surrounded by whitespace, this runs
631 COMMAND just once with the entire file list substituted there.
633 If there is no `*', but there is a `?' in COMMAND, surrounded by
634 whitespace, this runs COMMAND on each file individually with the
635 file name substituted for `?'.
637 Otherwise, this runs COMMAND on each file individually with the
638 file name added at the end of COMMAND (separated by a space).
640 `*' and `?' when not surrounded by whitespace have no special
641 significance for `dired-do-shell-command', and are passed through
642 normally to the shell, but you must confirm first.
644 If you want to use `*' as a shell wildcard with whitespace around
645 it, write `*\"\"' in place of just `*'. This is equivalent to just
646 `*' in the shell, but avoids Dired's special handling.
648 If COMMAND ends in `&', `;', or `;&', it is executed in the
649 background asynchronously, and the output appears in the buffer
650 `*Async Shell Command*'. When operating on multiple files and COMMAND
651 ends in `&', the shell command is executed on each file in parallel.
652 However, when COMMAND ends in `;' or `;&' then commands are executed
653 in the background on each file sequentially waiting for each command
654 to terminate before running the next command. You can also use
655 `dired-do-async-shell-command' that automatically adds `&'.
657 Otherwise, COMMAND is executed synchronously, and the output
658 appears in the buffer `*Shell Command Output*'.
660 This feature does not try to redisplay Dired buffers afterward, as
661 there's no telling what files COMMAND may have changed.
662 Type \\[dired-do-redisplay] to redisplay the marked files.
664 When COMMAND runs, its working directory is the top-level directory
665 of the Dired buffer, so output files usually are created there
666 instead of in a subdir.
668 In a noninteractive call (from Lisp code), you must specify
669 the list of file names explicitly with the FILE-LIST argument, which
670 can be produced by `dired-get-marked-files', for example."
