29 ;; This is a major mode for directory browsing and editing. It is
30 ;; documented in the Emacs manual.
32 ;; Rewritten in 1990/1991 to add tree features, file marking and
33 ;; sorting by Sebastian Kremer <sk@thp.uni-koeln.de>.

57 may contain even `F', `b', `i' and `s'. See also the variable
58 `dired-ls-F-marks-symlinks' concerning the `F' switch.
59 On systems such as MS-DOS and MS-Windows, which use `ls' emulation in Lisp,
60 some of the `ls' switches are not supported; see the doc string of
61 `insert-directory' in `ls-lisp.el' for more details."

94 Set this to t if `ls' (or whatever program is specified by
95 `insert-directory-program') with `-lF' marks the symbolic link
96 itself with a trailing @ (usually the case under Ultrix).
98 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
99 nil (the default), if it gives `bar@ -> foo', set it to t.
101 Dired checks if there is really a @ appended. Thus, if you have a
102 marking `ls' program on one host and a non-marking on another host, and
103 don't care about symbolic links which really end in a @, you can
104 always set this variable to t."

3569 Mark files with different names if PREDICATE is nil (or interactively
3570 with empty input at the predicate prompt).
3572 PREDICATE is a Lisp expression that can refer to the following variables:
3574 size1, size2 - file size in bytes
3575 mtime1, mtime2 - last modification time in seconds, as a float
3576 fa1, fa2 - list of file attributes
3577 returned by function `file-attributes'
3579 where 1 refers to attribute of file in the current dired buffer

3637 The output appears in the buffer `*Async Shell Command*'.
3642 Run a shell command COMMAND on the marked files.
3643 If no files are marked or a specific numeric prefix arg is given,
3645 The prompt mentions the file(s) or the marker, as appropriate.
3647 If there is a `*' in COMMAND, surrounded by whitespace, this runs
3648 COMMAND just once with the entire file list substituted there.
3650 If there is no `*', but there is a `?' in COMMAND, surrounded by
3651 whitespace, this runs COMMAND on each file individually with the
3652 file name substituted for `?'.
3654 Otherwise, this runs COMMAND on each file individually with the
3655 file name added at the end of COMMAND (separated by a space).
3657 `*' and `?' when not surrounded by whitespace have no special
3658 significance for `dired-do-shell-command', and are passed through

3662 If COMMAND produces output, it goes to a separate buffer.
3664 This feature does not try to redisplay Dired buffers afterward, as
3665 there's no telling what files COMMAND may have changed.
3668 When COMMAND runs, its working directory is the top-level directory
3669 of the Dired buffer, so output files usually are created there
3670 instead of in a subdir.
3672 In a noninteractive call (from Lisp code), you must specify
3673 the list of file names explicitly with the FILE-LIST argument, which
3674 can be produced by `dired-get-marked-files', for example.

3890 This function takes some pains to conform to `ls -lR' output.
3895 Go to previous subdirectory, regardless of level.
3896 When called interactively and not on a subdir line, go to this subdir's line.
3901 Go to end of header line of DIR in this dired buffer.
3902 Return value of point on success, otherwise return nil.
3908 Mark all files except `.' and `..' in current subdirectory.
3909 If the Dired buffer shows multiple directories, this command
3910 marks the files listed in the subdirectory that point is in.
3915 Remove all lines of current subdirectory.
3916 Lower levels are unaffected.
3921 Go up ARG levels in the dired tree.
3926 Go down in the dired tree.
3931 Hide or unhide the current subdirectory and move to next directory.
3932 Optional prefix arg is a repeat factor.
3938 Hide all subdirectories, leaving only their header lines.
3939 If there is already something hidden, make everything visible again.
3945 Set up isearch to search in Dired file names.
3946 Intended to be added to `isearch-mode-hook'.
3951 Search for a string using Isearch only in file names in the Dired buffer.
3956 Search for a regexp using Isearch only in file names in the Dired buffer.
3961 Search for a string through all marked files using Isearch.
3966 Search for a regexp through all marked files using Isearch.
3971 Search through all marked files for a match for REGEXP.
3972 Stops when a match is found.
3978 Do `query-replace-regexp' of FROM with TO, on all marked files.
3979 Third arg DELIMITED (prefix arg) means replace only word-delimited matches.
3986 Print the type of FILE, according to the `file' command.
3987 If FILE is a symbolic link and the optional argument DEREF-SYMLINKS is
3988 true then the type of the file linked to by FILE is printed instead.

3999 Jump to dired buffer corresponding to current buffer.
4000 If in a file, dired the current directory and move to file's line.
4001 If in Dired already, pop up a level and goto old directory's line.
4002 In case the proper dired file line cannot be found, refresh the dired
4003 buffer and try again.
4004 When OTHER-WINDOW is non-nil, jump to dired buffer in other window.
4005 Interactively with prefix argument, read FILE-NAME and
4006 move to its line in dired.
4011 Relative symlink all marked (or next ARG) files into a directory.
4012 Otherwise make a relative symbolic link to the current file.
4013 This creates relative symbolic links like
4015 foo -> ../bar/foo
4017 not absolute ones like
4019 foo -> /ugly/file/name/that/may/change/any/day/bar/foo
