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.
35 ;;; Code:
39 ;;; Customizable variables
42 "Directory editing."
47 "Handling marks in Dired."

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.
86 Note that if you set this option to nil, either through choice or
89 spaces. You might want to install ls from GNU Coreutils, which does
90 support this option. Alternatively, you might want to use Emacs's
92 \(setq ls-lisp-use-insert-directory-program nil)
93 \(require 'ls-lisp)
95 Note that `ls-lisp' does not support as many options as GNU ls, though.
96 For more details, see Info node `(emacs)ls in Lisp'."
103 "Name of chmod command (usually `chmod')."
108 "Name of touch command (usually `touch')."
113 "Informs Dired about how `ls -lF' marks symbolic links.
114 Set this to t if `ls' (or whatever program is specified by
115 `insert-directory-program') with `-lF' marks the symbolic link
116 itself with a trailing @ (usually the case under Ultrix).
118 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
119 nil (the default), if it gives `bar@ -> foo', set it to t.
121 Dired checks if there is really a @ appended. Thus, if you have a
122 marking `ls' program on one host and a non-marking on another host, and
123 don't care about symbolic links which really end in a @, you can
124 always set this variable to t."

139 "Controls marking of renamed files.
140 If t, files keep their previous marks when they are renamed.
141 If a character, renamed files (whether previously marked or not)
142 are afterward marked with that character."
148 "Controls marking of copied files.
149 If t, copied files are marked if and as the corresponding original files were.
150 If a character, copied files are unconditionally marked with that character."
156 "Controls marking of newly made hard links.
157 If t, they are marked if and as the files linked to were marked.
158 If a character, new links are unconditionally marked with that character."

165 If t, they are marked if and as the files linked to were marked.
166 If a character, new links are unconditionally marked with that character."
172 "If non-nil, Dired tries to guess a default target directory.
173 This means: if there is a Dired buffer displayed in the next
174 window, use its current directory, instead of this Dired buffer's
175 current directory.
177 The target is used in the prompt for file copy, rename etc."

3766 Compare file attributes of files in the current directory
3767 with file attributes in directory DIR2 using PREDICATE on pairs of files
3768 with the same name. Mark files for which PREDICATE returns non-nil.
3769 Mark files with different names if PREDICATE is nil (or interactively
3770 with empty input at the predicate prompt).
3772 PREDICATE is a Lisp expression that can refer to the following variables:
3774 size1, size2 - file size in bytes
3775 mtime1, mtime2 - last modification time in seconds, as a float
3776 fa1, fa2 - list of file attributes
3777 returned by function `file-attributes'
3779 where 1 refers to attribute of file in the current dired buffer
3780 and 2 to attribute of file in second dired buffer.
3782 Examples of PREDICATE:
3784 (> mtime1 mtime2) - mark newer files
3785 (not (= size1 size2)) - mark files with different sizes
3786 (not (string= (nth 8 fa1) (nth 8 fa2))) - mark files with different modes
3787 (not (and (= (nth 2 fa1) (nth 2 fa2)) - mark files with different UID

3828 with a prefix argument.
3833 Run a shell command COMMAND on the marked files asynchronously.
3835 Like `dired-do-shell-command' but if COMMAND doesn't end in ampersand,
3836 adds `* &' surrounded by whitespace and executes the command asynchronously.
3837 The output appears in the buffer `*Async Shell Command*'.
3842 Run a shell command COMMAND on the marked files.
3843 If no files are marked or a specific numeric prefix arg is given,
3845 The prompt mentions the file(s) or the marker, as appropriate.
3847 If there is a `*' in COMMAND, surrounded by whitespace, this runs
3848 COMMAND just once with the entire file list substituted there.
3850 If there is no `*', but there is a `?' in COMMAND, surrounded by
3851 whitespace, this runs COMMAND on each file individually with the
3852 file name substituted for `?'.
3854 Otherwise, this runs COMMAND on each file individually with the
3855 file name added at the end of COMMAND (separated by a space).
3857 `*' and `?' when not surrounded by whitespace have no special
3858 significance for `dired-do-shell-command', and are passed through
3859 normally to the shell, but you must confirm first.
3861 If you want to use `*' as a shell wildcard with whitespace around
3863 `*' in the shell, but avoids Dired's special handling.
3865 If COMMAND produces output, it goes to a separate buffer.
3867 This feature does not try to redisplay Dired buffers afterward, as
3868 there's no telling what files COMMAND may have changed.
3871 When COMMAND runs, its working directory is the top-level directory
3872 of the Dired buffer, so output files usually are created there
3873 instead of in a subdir.
3875 In a noninteractive call (from Lisp code), you must specify
3876 the list of file names explicitly with the FILE-LIST argument, which
3877 can be produced by `dired-get-marked-files', for example.
3887 Kill all marked lines (not the files).
3888 With a prefix argument, kill that many lines starting with the current line.
3889 \(A negative argument kills backward.)
3890 If you use this command with a prefix argument to kill the line
3891 for a file that is a directory, which you have inserted in the
3892 Dired buffer as a subdirectory, then it deletes that subdirectory
3893 from the buffer as well.
3894 To kill an entire subdirectory (without killing its line in the
3895 parent directory), go to its directory header line and use this
3896 command with a prefix argument (the value does not matter).
3906 Format PROMPT with ARGS, query user, and store the result in SYM.
3907 The return value is either nil or t.
3909 The user may type y or SPC to accept once; n or DEL to skip once;
3910 ! to accept this and subsequent queries; or q or ESC to decline
3911 this and subsequent queries.
3913 If SYM is already bound to a non-nil value, this function may
3914 return automatically without querying the user. If SYM is !,
3915 return t; if SYM is q or ESC, return nil.
3920 Compress or uncompress marked (or next ARG) files.
3925 Byte compile marked (or next ARG) Emacs Lisp files.
3930 Load the marked (or next ARG) Emacs Lisp files.
3935 Redisplay all marked (or next ARG) files.
3936 If on a subdir line, redisplay that subdirectory. In that case,
3937 a prefix arg lets you edit the `ls' switches used for the new listing.
3939 Dired remembers switches specified with a prefix arg, so that reverting
3940 the buffer will not reset them. However, using `dired-undo' to re-insert
3941 or delete subdirectories can bypass this machinery. Hence, you sometimes
3942 may have to reset some subdirectory switches after a `dired-undo'.
3943 You can reset all subdirectory switches to the default using
3945 See Info node `(emacs)Subdir switches' for more details.
3960 Create or update the line for FILE in all Dired buffers it would belong in.
3975 Create a directory called DIRECTORY.
3976 If DIRECTORY already exists, signal an error.
3981 Copy all marked (or next ARG) files, or copy the current file.
3982 When operating on just the current file, prompt for the new name.
3984 When operating on multiple or marked files, prompt for a target
3985 directory, and make the new copies in that directory, with the
3986 same names as the original files. The initial suggestion for the
3987 target directory is the Dired buffer's current directory (or, if
3988 `dired-dwim-target' is non-nil, the current directory of a
3989 neighboring Dired window).
3991 If `dired-copy-preserve-time' is non-nil, this command preserves
3992 the modification time of each old file in the copy, similar to
3995 This command copies symbolic links by creating new ones, similar
4001 Make symbolic links to current file or all marked (or next ARG) files.
4002 When operating on just the current file, you specify the new name.
4003 When operating on multiple or marked files, you specify a directory
4004 and new symbolic links are made in that directory
4005 with the same names that the files currently have. The default
4006 suggested for the target directory depends on the value of
4007 `dired-dwim-target', which see.
4014 Add names (hard links) current file or all marked (or next ARG) files.
4015 When operating on just the current file, you specify the new name.
4016 When operating on multiple or marked files, you specify a directory
4017 and new hard links are made in that directory
4018 with the same names that the files currently have. The default
4019 suggested for the target directory depends on the value of
4020 `dired-dwim-target', which see.
4025 Rename current file or all marked (or next ARG) files.
4026 When renaming just the current file, you specify the new name.
4027 When renaming multiple or marked files, you specify a directory.
4028 This command also renames any buffers that are visiting the files.
4029 The default suggested for the target directory depends on the value
4030 of `dired-dwim-target', which see.
4035 Rename selected files whose names match REGEXP to NEWNAME.
4037 With non-zero prefix argument ARG, the command operates on the next ARG
4038 files. Otherwise, it operates on all the marked files, or the current
4039 file if none are marked.
4041 As each match is found, the user must type a character saying
4044 REGEXP defaults to the last regexp used.
4046 With a zero prefix arg, renaming by regexp affects the absolute file name.
4047 Normally, only the non-directory part of the file name is used and changed.
4052 Copy selected files whose names match REGEXP to NEWNAME.
4053 See function `dired-do-rename-regexp' for more info.
4058 Hardlink selected files whose names match REGEXP to NEWNAME.
4059 See function `dired-do-rename-regexp' for more info.
4064 Symlink selected files whose names match REGEXP to NEWNAME.
4065 See function `dired-do-rename-regexp' for more info.
4070 Rename all marked (or next ARG) files to upper case.
4075 Rename all marked (or next ARG) files to lower case.
4080 Insert this subdirectory into the same dired buffer.
4082 else inserts it at its natural place (as `ls -lR' would have done).
4083 With a prefix arg, you may edit the ls switches used for this listing.
4084 You can add `R' to the switches to expand the whole tree starting at
4085 this subdirectory.
4086 This function takes some pains to conform to `ls -lR' output.
4088 Dired remembers switches specified with a prefix arg, so that reverting
4089 the buffer will not reset them. However, using `dired-undo' to re-insert
4090 or delete subdirectories can bypass this machinery. Hence, you sometimes
4091 may have to reset some subdirectory switches after a `dired-undo'.
4092 You can reset all subdirectory switches to the default using
4094 See Info node `(emacs)Subdir switches' for more details.
4099 Insert this subdirectory into the same Dired buffer.
4100 If it is already present, overwrite the previous entry;
4101 otherwise, insert it at its natural place (as `ls -lR' would
4102 have done).
4103 With a prefix arg, you may edit the `ls' switches used for this listing.
4104 You can add `R' to the switches to expand the whole tree starting at
4105 this subdirectory.
4106 This function takes some pains to conform to `ls -lR' output.
4111 Go to previous subdirectory, regardless of level.
4112 When called interactively and not on a subdir line, go to this subdir's line.
4117 Go to end of header line of DIR in this dired buffer.
4118 Return value of point on success, otherwise return nil.
4124 Mark all files except `.' and `..' in current subdirectory.
4125 If the Dired buffer shows multiple directories, this command
4126 marks the files listed in the subdirectory that point is in.
4131 Remove all lines of current subdirectory.
4132 Lower levels are unaffected.
4137 Go up ARG levels in the dired tree.
4142 Go down in the dired tree.
4147 Hide or unhide the current subdirectory and move to next directory.
4148 Optional prefix arg is a repeat factor.
4154 Hide all subdirectories, leaving only their header lines.
4155 If there is already something hidden, make everything visible again.
4161 Set up isearch to search in Dired file names.
4162 Intended to be added to `isearch-mode-hook'.
4167 Search for a string using Isearch only in file names in the Dired buffer.
4172 Search for a regexp using Isearch only in file names in the Dired buffer.
4177 Search for a string through all marked files using Isearch.
4182 Search for a regexp through all marked files using Isearch.
4187 Search through all marked files for a match for REGEXP.
4188 Stops when a match is found.
4194 Do `query-replace-regexp' of FROM with TO, on all marked files.
4195 Third arg DELIMITED (prefix arg) means replace only word-delimited matches.
4202 Print the type of FILE, according to the `file' command.
4203 If you give a prefix to this command, and FILE is a symbolic
4204 link, then the type of the file linked to by FILE is printed
4205 instead.
