28 ;; This is a major mode for directory browsing and editing.
29 ;; It is documented in the Emacs manual.
31 ;; Rewritten in 1990/1991 to add tree features, file marking and
32 ;; sorting by Sebastian Kremer <sk@thp.uni-koeln.de>.
33 ;; Finished up by rms in 1992.

54 "Switches passed to `ls' for Dired. MUST contain the `l' option.
55 May contain all other options that don't contradict `-l';
56 may contain even `F', `b', `i' and `s'. See also the variable
57 `dired-ls-F-marks-symlinks' concerning the `F' switch.
58 On systems such as MS-DOS and MS-Windows, which use `ls' emulation in Lisp,
59 some of the `ls' switches are not supported; see the doc string of
60 `insert-directory' in `ls-lisp.el' for more details."
65 "If non-nil, switches passed to `ls' for inserting subdirectories.
66 If nil, `dired-listing-switches' is used."
76 "Name of chown command (usually `chown')."
82 The special value of `unspecified' means to check explicitly, and
83 save the result in this variable. This is performed the first
84 time `dired-insert-directory' is called."
91 "Name of chmod command (usually `chmod')."
96 "Name of touch command (usually `touch')."
101 "Informs Dired about how `ls -lF' marks symbolic links.
102 Set this to t if `ls' (or whatever program is specified by
103 `insert-directory-program') with `-lF' marks the symbolic link
104 itself with a trailing @ (usually the case under Ultrix).
106 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
107 nil (the default), if it gives `bar@ -> foo', set it to t.
109 Dired checks if there is really a @ appended. Thus, if you have a
110 marking `ls' program on one host and a non-marking on another host, and
111 don't care about symbolic links which really end in a @, you can
112 always set this variable to t."

128 If t, files keep their previous marks when they are renamed.
129 If a character, renamed files (whether previously marked or not)
130 are afterward marked with that character."
136 "Controls marking of copied files.
137 If t, copied files are marked if and as the corresponding original files were.
138 If a character, copied files are unconditionally marked with that character."
144 "Controls marking of newly made hard links.
145 If t, they are marked if and as the files linked to were marked.
146 If a character, new links are unconditionally marked with that character."

154 If a character, new links are unconditionally marked with that character."
160 "If non-nil, Dired tries to guess a default target directory.
161 This means: if there is a dired buffer displayed in the next window,
162 use its current subdir, instead of the current subdir of this dired buffer.

198 "Hook run after each time a file or directory is read by Dired.

3658 with the same name. Mark files for which PREDICATE returns non-nil.
3659 Mark files with different names if PREDICATE is nil (or interactively
3660 with empty input at the predicate prompt).
3662 PREDICATE is a Lisp expression that can refer to the following variables:
3664 size1, size2 - file size in bytes
3665 mtime1, mtime2 - last modification time in seconds, as a float
3666 fa1, fa2 - list of file attributes
3667 returned by function `file-attributes'
3669 where 1 refers to attribute of file in the current dired buffer
3670 and 2 to attribute of file in second dired buffer.
3672 Examples of PREDICATE:
3674 (> mtime1 mtime2) - mark newer files
3675 (not (= size1 size2)) - mark files with different sizes
3676 (not (string= (nth 8 fa1) (nth 8 fa2))) - mark files with different modes
3677 (not (and (= (nth 2 fa1) (nth 2 fa2)) - mark files with different UID

3723 Run a shell command COMMAND on the marked files asynchronously.
3725 Like `dired-do-shell-command' but if COMMAND doesn't end in ampersand,
3726 adds `* &' surrounded by whitespace and executes the command asynchronously.
3727 The output appears in the buffer `*Async Shell Command*'.
3732 Run a shell command COMMAND on the marked files.
3733 If no files are marked or a specific numeric prefix arg is given,
3735 The prompt mentions the file(s) or the marker, as appropriate.
3737 If there is a `*' in COMMAND, surrounded by whitespace, this runs
3738 COMMAND just once with the entire file list substituted there.
3740 If there is no `*', but there is a `?' in COMMAND, surrounded by
3741 whitespace, this runs COMMAND on each file individually with the
3742 file name substituted for `?'.
3744 Otherwise, this runs COMMAND on each file individually with the
3745 file name added at the end of COMMAND (separated by a space).
3747 `*' and `?' when not surrounded by whitespace have no special
3748 significance for `dired-do-shell-command', and are passed through
3749 normally to the shell, but you must confirm first. To pass `*' by
3752 If COMMAND produces output, it goes to a separate buffer.
3754 This feature does not try to redisplay Dired buffers afterward, as
3755 there's no telling what files COMMAND may have changed.
3758 When COMMAND runs, its working directory is the top-level directory
3759 of the Dired buffer, so output files usually are created there
3760 instead of in a subdir.
3762 In a noninteractive call (from Lisp code), you must specify
3763 the list of file names explicitly with the FILE-LIST argument, which
3764 can be produced by `dired-get-marked-files', for example.
3774 Kill all marked lines (not the files).
3775 With a prefix argument, kill that many lines starting with the current line.
3776 \(A negative argument kills backward.)
3777 If you use this command with a prefix argument to kill the line
3778 for a file that is a directory, which you have inserted in the
3779 Dired buffer as a subdirectory, then it deletes that subdirectory
3780 from the buffer as well.
3781 To kill an entire subdirectory (without killing its line in the
3782 parent directory), go to its directory header line and use this
3783 command with a prefix argument (the value does not matter).
3793 Format PROMPT with ARGS, query user, and store the result in SYM.
3794 The return value is either nil or t.
3796 The user may type y or SPC to accept once; n or DEL to skip once;
3797 ! to accept this and subsequent queries; or q or ESC to decline
3798 this and subsequent queries.
3800 If SYM is already bound to a non-nil value, this function may
3801 return automatically without querying the user. If SYM is !,
3802 return t; if SYM is q or ESC, return nil.
3807 Compress or uncompress marked (or next ARG) files.
3812 Byte compile marked (or next ARG) Emacs Lisp files.
3817 Load the marked (or next ARG) Emacs Lisp files.
3822 Redisplay all marked (or next ARG) files.
3823 If on a subdir line, redisplay that subdirectory. In that case,
3824 a prefix arg lets you edit the `ls' switches used for the new listing.
3826 Dired remembers switches specified with a prefix arg, so that reverting
3827 the buffer will not reset them. However, using `dired-undo' to re-insert
3828 or delete subdirectories can bypass this machinery. Hence, you sometimes
3829 may have to reset some subdirectory switches after a `dired-undo'.
3830 You can reset all subdirectory switches to the default using
3832 See Info node `(emacs)Subdir switches' for more details.
3847 Create or update the line for FILE in all Dired buffers it would belong in.
3862 Create a directory called DIRECTORY.
3863 If DIRECTORY already exists, signal an error.
3868 Copy all marked (or next ARG) files, or copy the current file.
3869 This normally preserves the last-modified date when copying.
3870 When operating on just the current file, you specify the new name.
3871 When operating on multiple or marked files, you specify a directory,
3872 and new copies of these files are made in that directory
3873 with the same names that the files currently have. The default
3874 suggested for the target directory depends on the value of
3875 `dired-dwim-target', which see.
3877 This command copies symbolic links by creating new ones,
3878 like `cp -d'.
3883 Make symbolic links to current file or all marked (or next ARG) files.
3884 When operating on just the current file, you specify the new name.
3885 When operating on multiple or marked files, you specify a directory
3886 and new symbolic links are made in that directory
3887 with the same names that the files currently have. The default
3888 suggested for the target directory depends on the value of
3889 `dired-dwim-target', which see.
3896 Add names (hard links) current file or all marked (or next ARG) files.
3897 When operating on just the current file, you specify the new name.
3898 When operating on multiple or marked files, you specify a directory
3899 and new hard links are made in that directory
3900 with the same names that the files currently have. The default
3901 suggested for the target directory depends on the value of
3902 `dired-dwim-target', which see.
3907 Rename current file or all marked (or next ARG) files.
3908 When renaming just the current file, you specify the new name.
3909 When renaming multiple or marked files, you specify a directory.
3910 This command also renames any buffers that are visiting the files.
3911 The default suggested for the target directory depends on the value
3912 of `dired-dwim-target', which see.
3917 Rename selected files whose names match REGEXP to NEWNAME.
3919 With non-zero prefix argument ARG, the command operates on the next ARG
3920 files. Otherwise, it operates on all the marked files, or the current
3921 file if none are marked.
3923 As each match is found, the user must type a character saying
3926 REGEXP defaults to the last regexp used.
3928 With a zero prefix arg, renaming by regexp affects the absolute file name.
3929 Normally, only the non-directory part of the file name is used and changed.

3952 Rename all marked (or next ARG) files to upper case.
3957 Rename all marked (or next ARG) files to lower case.
3962 Insert this subdirectory into the same dired buffer.
3964 else inserts it at its natural place (as `ls -lR' would have done).
3965 With a prefix arg, you may edit the ls switches used for this listing.
3966 You can add `R' to the switches to expand the whole tree starting at
3967 this subdirectory.
3968 This function takes some pains to conform to `ls -lR' output.
3970 Dired remembers switches specified with a prefix arg, so that reverting
3971 the buffer will not reset them. However, using `dired-undo' to re-insert
3972 or delete subdirectories can bypass this machinery. Hence, you sometimes
3973 may have to reset some subdirectory switches after a `dired-undo'.
3974 You can reset all subdirectory switches to the default using
3976 See Info node `(emacs)Subdir switches' for more details.
3981 Insert this subdirectory into the same dired buffer.
3982 If it is already present, overwrites previous entry,
3983 else inserts it at its natural place (as `ls -lR' would have done).
3984 With a prefix arg, you may edit the `ls' switches used for this listing.
3985 You can add `R' to the switches to expand the whole tree starting at
3986 this subdirectory.
3987 This function takes some pains to conform to `ls -lR' output.
3992 Go to previous subdirectory, regardless of level.
3993 When called interactively and not on a subdir line, go to this subdir's line.
3998 Go to end of header line of DIR in this dired buffer.
3999 Return value of point on success, otherwise return nil.
4005 Mark all files except `.' and `..' in current subdirectory.
4006 If the Dired buffer shows multiple directories, this command
4007 marks the files listed in the subdirectory that point is in.
4012 Remove all lines of current subdirectory.
4013 Lower levels are unaffected.
4018 Go up ARG levels in the dired tree.
4023 Go down in the dired tree.
4028 Hide or unhide the current subdirectory and move to next directory.
4029 Optional prefix arg is a repeat factor.
4035 Hide all subdirectories, leaving only their header lines.
4036 If there is already something hidden, make everything visible again.
4042 Set up isearch to search in Dired file names.
4043 Intended to be added to `isearch-mode-hook'.
4048 Search for a string using Isearch only in file names in the Dired buffer.
4053 Search for a regexp using Isearch only in file names in the Dired buffer.
4058 Search for a string through all marked files using Isearch.
4063 Search for a regexp through all marked files using Isearch.
4068 Search through all marked files for a match for REGEXP.
4069 Stops when a match is found.
4075 Do `query-replace-regexp' of FROM with TO, on all marked files.
4076 Third arg DELIMITED (prefix arg) means replace only word-delimited matches.
4083 Print the type of FILE, according to the `file' command.
4084 If FILE is a symbolic link and the optional argument DEREF-SYMLINKS is
4085 true then the type of the file linked to by FILE is printed instead.

4096 Jump to dired buffer corresponding to current buffer.
4097 If in a file, dired the current directory and move to file's line.
4098 If in Dired already, pop up a level and goto old directory's line.
4099 In case the proper dired file line cannot be found, refresh the dired
4100 buffer and try again.
4101 When OTHER-WINDOW is non-nil, jump to dired buffer in other window.
4102 Interactively with prefix argument, read FILE-NAME and
4103 move to its line in dired.
4113 Relative symlink all marked (or next ARG) files into a directory.
4114 Otherwise make a relative symbolic link to the current file.
4115 This creates relative symbolic links like
4117 foo -> ../bar/foo
4119 not absolute ones like
