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.

55 "Switches passed to `ls' for Dired. MUST contain the `l' option.
56 May contain all other options that don't contradict `-l';
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."
66 "If non-nil, switches passed to `ls' for inserting subdirectories.
67 If nil, `dired-listing-switches' is used."
77 "Name of chown command (usually `chown')."
83 The special value of `unspecified' means to check explicitly, and
84 save the result in this variable. This is performed the first
85 time `dired-insert-directory' is called.
87 Note that if you set this option to nil, either through choice or
90 spaces. You might want to install ls from GNU Coreutils, which does
91 support this option. Alternatively, you might want to use Emacs's
93 (setq ls-lisp-use-insert-directory-program nil)
94 (require 'ls-lisp)
96 Note that `ls-lisp' does not support as many options as GNU ls, though.
97 For more details, see Info node `(emacs)ls in Lisp'."
104 "Name of chmod command (usually `chmod')."
109 "Name of touch command (usually `touch')."
114 "Informs Dired about how `ls -lF' marks symbolic links.
115 Set this to t if `ls' (or whatever program is specified by
116 `insert-directory-program') with `-lF' marks the symbolic link
117 itself with a trailing @ (usually the case under Ultrix).
119 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
120 nil (the default), if it gives `bar@ -> foo', set it to t.
122 Dired checks if there is really a @ appended. Thus, if you have a
123 marking `ls' program on one host and a non-marking on another host, and
124 don't care about symbolic links which really end in a @, you can
125 always set this variable to t."

140 "Controls marking of renamed files.
141 If t, files keep their previous marks when they are renamed.
142 If a character, renamed files (whether previously marked or not)
143 are afterward marked with that character.
144 This option affects only files renamed by `dired-do-rename' and
145 `dired-do-rename-regexp'. See `wdired-keep-marker-rename'
146 if you want to do the same for files renamed in WDired mode."
152 "Controls marking of copied files.
153 If t, copied files are marked if and as the corresponding original files were.
154 If a character, copied files are unconditionally marked with that character."
160 "Controls marking of newly made hard links.
161 If t, they are marked if and as the files linked to were marked.
162 If a character, new links are unconditionally marked with that character."
168 "Controls marking of newly made symbolic links.
169 If t, they are marked if and as the files linked to were marked.
170 If a character, new links are unconditionally marked with that character."
176 "If non-nil, Dired tries to guess a default target directory.
177 This means: if there is a Dired buffer displayed in the next
178 window, use its current directory, instead of this Dired buffer's
179 current directory.
181 The target is used in the prompt for file copy, rename etc."

217 with the buffer narrowed to the listing."

1046 ;; To work around this problem, we here add spaces to try and

4021 If there is a `*' in COMMAND, surrounded by whitespace, this runs
4022 COMMAND just once with the entire file list substituted there.
4024 If there is no `*', but there is a `?' in COMMAND, surrounded by
4025 whitespace, this runs COMMAND on each file individually with the
4026 file name substituted for `?'.
4028 Otherwise, this runs COMMAND on each file individually with the
4029 file name added at the end of COMMAND (separated by a space).
4031 `*' and `?' when not surrounded by whitespace have no special
4032 significance for `dired-do-shell-command', and are passed through
4033 normally to the shell, but you must confirm first.
4035 If you want to use `*' as a shell wildcard with whitespace around
4037 `*' in the shell, but avoids Dired's special handling.
4039 If COMMAND ends in `&', `;', or `;&', it is executed in the
4040 background asynchronously, and the output appears in the buffer
4041 `*Async Shell Command*'. When operating on multiple files and COMMAND
4042 ends in `&', the shell command is executed on each file in parallel.
4043 However, when COMMAND ends in `;' or `;&' then commands are executed
4044 in the background on each file sequentially waiting for each command
4045 to terminate before running the next command. You can also use
4046 `dired-do-async-shell-command' that automatically adds `&'.
4048 Otherwise, COMMAND is executed synchronously, and the output
4049 appears in the buffer `*Shell Command Output*'.
4051 This feature does not try to redisplay Dired buffers afterward, as
4052 there's no telling what files COMMAND may have changed.
4055 When COMMAND runs, its working directory is the top-level directory
4056 of the Dired buffer, so output files usually are created there
4057 instead of in a subdir.
4059 In a noninteractive call (from Lisp code), you must specify
4060 the list of file names explicitly with the FILE-LIST argument, which
4061 can be produced by `dired-get-marked-files', for example.
4071 Kill all marked lines (not the files).
4072 With a prefix argument, kill that many lines starting with the current line.
4073 \(A negative argument kills backward.)
4074 If you use this command with a prefix argument to kill the line
4075 for a file that is a directory, which you have inserted in the
4076 Dired buffer as a subdirectory, then it deletes that subdirectory
4077 from the buffer as well.
4078 To kill an entire subdirectory (without killing its line in the
4079 parent directory), go to its directory header line and use this
4080 command with a prefix argument (the value does not matter).
4090 Format PROMPT with ARGS, query user, and store the result in SYM.
4091 The return value is either nil or t.
4093 The user may type y or SPC to accept once; n or DEL to skip once;
4094 ! to accept this and subsequent queries; or q or ESC to decline
4095 this and subsequent queries.
4097 If SYM is already bound to a non-nil value, this function may
4098 return automatically without querying the user. If SYM is !,
4099 return t; if SYM is q or ESC, return nil.
4104 Compress or uncompress marked (or next ARG) files.
4109 Byte compile marked (or next ARG) Emacs Lisp files.
4114 Load the marked (or next ARG) Emacs Lisp files.
4119 Redisplay all marked (or next ARG) files.
4120 If on a subdir line, redisplay that subdirectory. In that case,
4121 a prefix arg lets you edit the `ls' switches used for the new listing.
4123 Dired remembers switches specified with a prefix arg, so that reverting
4124 the buffer will not reset them. However, using `dired-undo' to re-insert
4125 or delete subdirectories can bypass this machinery. Hence, you sometimes
4126 may have to reset some subdirectory switches after a `dired-undo'.
4127 You can reset all subdirectory switches to the default using
4129 See Info node `(emacs)Subdir switches' for more details.
4144 Create or update the line for FILE in all Dired buffers it would belong in.
4159 Create a directory called DIRECTORY.
4160 If DIRECTORY already exists, signal an error.
4165 Copy all marked (or next ARG) files, or copy the current file.
4166 When operating on just the current file, prompt for the new name.
4168 When operating on multiple or marked files, prompt for a target
4169 directory, and make the new copies in that directory, with the
4170 same names as the original files. The initial suggestion for the
4171 target directory is the Dired buffer's current directory (or, if
4172 `dired-dwim-target' is non-nil, the current directory of a
4173 neighboring Dired window).
4175 If `dired-copy-preserve-time' is non-nil, this command preserves
4176 the modification time of each old file in the copy, similar to
4179 This command copies symbolic links by creating new ones, similar
4185 Make symbolic links to current file or all marked (or next ARG) files.
4186 When operating on just the current file, you specify the new name.
4187 When operating on multiple or marked files, you specify a directory
4188 and new symbolic links are made in that directory
4189 with the same names that the files currently have. The default
4190 suggested for the target directory depends on the value of
4191 `dired-dwim-target', which see.
4198 Add names (hard links) current file or all marked (or next ARG) files.
4199 When operating on just the current file, you specify the new name.
4200 When operating on multiple or marked files, you specify a directory
4201 and new hard links are made in that directory
4202 with the same names that the files currently have. The default
4203 suggested for the target directory depends on the value of
4204 `dired-dwim-target', which see.
4209 Rename current file or all marked (or next ARG) files.
4210 When renaming just the current file, you specify the new name.
4211 When renaming multiple or marked files, you specify a directory.
4212 This command also renames any buffers that are visiting the files.
4213 The default suggested for the target directory depends on the value
4214 of `dired-dwim-target', which see.
4219 Rename selected files whose names match REGEXP to NEWNAME.
4221 With non-zero prefix argument ARG, the command operates on the next ARG
4222 files. Otherwise, it operates on all the marked files, or the current
4223 file if none are marked.
4225 As each match is found, the user must type a character saying
4228 REGEXP defaults to the last regexp used.
4230 With a zero prefix arg, renaming by regexp affects the absolute file name.
4231 Normally, only the non-directory part of the file name is used and changed.
4236 Copy selected files whose names match REGEXP to NEWNAME.
4237 See function `dired-do-rename-regexp' for more info.
4242 Hardlink selected files whose names match REGEXP to NEWNAME.
4243 See function `dired-do-rename-regexp' for more info.
4248 Symlink selected files whose names match REGEXP to NEWNAME.
4249 See function `dired-do-rename-regexp' for more info.
4254 Rename all marked (or next ARG) files to upper case.
4259 Rename all marked (or next ARG) files to lower case.
4264 Insert this subdirectory into the same dired buffer.
4266 else inserts it at its natural place (as `ls -lR' would have done).
4267 With a prefix arg, you may edit the ls switches used for this listing.
4268 You can add `R' to the switches to expand the whole tree starting at
4269 this subdirectory.
4270 This function takes some pains to conform to `ls -lR' output.
4272 Dired remembers switches specified with a prefix arg, so that reverting
4273 the buffer will not reset them. However, using `dired-undo' to re-insert
4274 or delete subdirectories can bypass this machinery. Hence, you sometimes
4275 may have to reset some subdirectory switches after a `dired-undo'.
4276 You can reset all subdirectory switches to the default using
4278 See Info node `(emacs)Subdir switches' for more details.
4283 Insert this subdirectory into the same Dired buffer.
4284 If it is already present, overwrite the previous entry;
4285 otherwise, insert it at its natural place (as `ls -lR' would
4286 have done).
4287 With a prefix arg, you may edit the `ls' switches used for this listing.
4288 You can add `R' to the switches to expand the whole tree starting at
4289 this subdirectory.
4290 This function takes some pains to conform to `ls -lR' output.
4295 Go to previous subdirectory, regardless of level.
4296 When called interactively and not on a subdir line, go to this subdir's line.
4301 Go to end of header line of DIR in this dired buffer.
4302 Return value of point on success, otherwise return nil.
4308 Mark all files except `.' and `..' in current subdirectory.
4309 If the Dired buffer shows multiple directories, this command
4310 marks the files listed in the subdirectory that point is in.
4315 Remove all lines of current subdirectory.
4316 Lower levels are unaffected.
4321 Go up ARG levels in the dired tree.
4326 Go down in the dired tree.
4331 Hide or unhide the current subdirectory and move to next directory.
4332 Optional prefix arg is a repeat factor.
4338 Hide all subdirectories, leaving only their header lines.
4339 If there is already something hidden, make everything visible again.
4345 Set up isearch to search in Dired file names.
4346 Intended to be added to `isearch-mode-hook'.
4351 Search for a string using Isearch only in file names in the Dired buffer.
4356 Search for a regexp using Isearch only in file names in the Dired buffer.
4361 Search for a string through all marked files using Isearch.
4366 Search for a regexp through all marked files using Isearch.
4371 Search through all marked files for a match for REGEXP.
4372 Stops when a match is found.
4378 Do `query-replace-regexp' of FROM with TO, on all marked files.
4379 Third arg DELIMITED (prefix arg) means replace only word-delimited matches.
4386 Print the type of FILE, according to the `file' command.
4387 If you give a prefix to this command, and FILE is a symbolic
4388 link, then the type of the file linked to by FILE is printed
4389 instead.
