Dired makes an Emacs buffer containing a listing of a directory, and
|
|
|
|
optionally some of its subdirectories as well. You can use the normal
|
|
|
|
Emacs commands to move around in this buffer, and special Dired commands
|
|
|
|
to operate on the files listed.
|
|
|
|
|
2001-06-07 10:23:13 +00:00
|
|
|
The Dired buffer is ``read-only,'' and inserting text in it is not
|
|
|
|
useful, so ordinary printing characters such as @kbd{d} and @kbd{x} are
|
|
|
|
used for special Dired commands. Some Dired commands @dfn{mark} or
|
|
|
|
@dfn{flag} the @dfn{current file} (that is, the file on the current
|
|
|
|
line); other commands operate on the marked files or on the flagged
|
|
|
|
files.

|
|
|
|
@vindex dired-listing-switches
|
|
|
|
To invoke Dired, do @kbd{C-x d} or @kbd{M-x dired}. The command reads
|
|
|
|
a directory name or wildcard file name pattern as a minibuffer argument
|
|
|
|
to specify which files to list. Where @code{dired} differs from
|
|
|
|
@code{list-directory} is in putting the buffer into Dired mode so that
|
|
|
|
the special commands of Dired are available.
|
|
|
|
|
|
|
|
The variable @code{dired-listing-switches} specifies the options to
|
|
|
|
give to @code{ls} for listing directory; this string @emph{must} contain
|
|
|
|
@samp{-l}. If you use a numeric prefix argument with the @code{dired}
|
|
|
|
command, you can specify the @code{ls} switches with the minibuffer
|
|
|
|
before you enter the directory specification.

To display the Dired buffer in another window rather than in the

selected window, use @kbd{C-x 4 d} (@code{dired-other-window}) instead
|
|

All the usual Emacs cursor motion commands are available in Dired
|
|
|
|
buffers. Some special-purpose cursor motion commands are also
|
|
|
|
provided. The keys @kbd{C-n} and @kbd{C-p} are redefined to put the
|
|
|
|
cursor at the beginning of the file name on the line, rather than at the
|
|
|
|
beginning of the line.

|
|

|
@kindex SPC @r{(Dired)}
|
|
|
|
For extra convenience, @key{SPC} and @kbd{n} in Dired are equivalent
|
|
|
|
to @kbd{C-n}. @kbd{p} is equivalent to @kbd{C-p}. (Moving by lines is
|
|
|
|
so common in Dired that it deserves to be easy to type.) @key{DEL}
|
|
|
|
(move up and unflag) is often useful simply for moving up.

One of the most frequent uses of Dired is to first @dfn{flag} files for

deletion, then delete the files that were flagged.

@findex dired-flag-file-deletion
|
|
|
|
You can flag a file for deletion by moving to the line describing the
|
|
|
|
file and typing @kbd{d} (@code{dired-flag-file-deletion}). The deletion flag is visible as a @samp{D} at
|
|
|
|
the beginning of the line. This command moves point to the next line,
|
|
|
|
so that repeated @kbd{d} commands flag successive files. A numeric
|
|
|
|
argument serves as a repeat count.

@vindex dired-recursive-deletes
|
2001-02-17 16:43:14 +00:00
|
|
|
The variable @code{dired-recursive-deletes} controls whether the
|
|
|
|
delete command will delete non-empty directories (including their
|
|
|
|
contents). The default is to delete only empty directories.

|
@kindex u @r{(Dired deletion)}
|
|
|
|
@kindex DEL @r{(Dired)}
|
|
|
|
The files are flagged for deletion rather than deleted immediately to
|
|
|
|
reduce the danger of deleting a file accidentally. Until you direct
|
2001-04-26 00:29:21 +00:00
|
|
|
Dired to delete the flagged files, you can remove deletion flags using
|
1999-09-29 15:17:24 +00:00
|
|
|
the commands @kbd{u} and @key{DEL}. @kbd{u} (@code{dired-unmark}) works
|
|
|
|
just like @kbd{d}, but removes flags rather than making flags.
|
|
|
|
@key{DEL} (@code{dired-unmark-backward}) moves upward, removing flags;
|
|
|
|
it is like @kbd{u} with argument @minus{}1.

|
|
|
To delete the flagged files, type @kbd{x} (@code{dired-do-flagged-delete}).
|
|
|
|
(This is also known as @dfn{expunging}.)
|
1999-09-29 15:17:24 +00:00
|
|
|
This command first displays a list of all the file names flagged for
|
|
|
|
deletion, and requests confirmation with @kbd{yes}. If you confirm,
|
|
|
|
Dired deletes the flagged files, then deletes their lines from the text
|
|
|
|
of the Dired buffer. The shortened Dired buffer remains selected.
|
|
|
|
|
|
|
|
If you answer @kbd{no} or quit with @kbd{C-g} when asked to confirm, you
|
|
|
|
return immediately to Dired, with the deletion flags still present in
|
|
|
|
the buffer, and no files actually deleted.

@cindex marking many files (in Dired)
|
2001-04-26 00:29:21 +00:00
|
|
|
Instead of flagging a file with @samp{D}, you can @dfn{mark} the
|
|
|
|
file with some other character (usually @samp{*}). Most Dired
|
|
|
|
commands to operate on files use the files marked with @samp{*}, the
|
|
|
|
exception being @kbd{x} which deletes the flagged files.
|

2001-03-02 12:27:41 +00:00

character---do not use @key{RET} to terminate it. See the description

2001-03-04 07:05:37 +00:00

With a numeric argument, this command queries about each marked file,

asking whether to remove its mark. You can answer @kbd{y} meaning yes,

1999-09-29 15:17:24 +00:00
|
|
|
Toggle all marks (@code{dired-do-toggle}): files marked with @samp{*}
|
|
|
|
become unmarked, and unmarked files are marked with @samp{*}. Files
|
|
|
|
marked in any other way are not affected.

@findex dired-change-marks
|
2001-03-02 12:27:41 +00:00
|
|
|
Replace all marks that use the character @var{old-markchar} with marks
|
|
|
|
that use the character @var{new-markchar} (@code{dired-change-marks}).
|
|
|
|
This command is the primary way to create or use marks other than
|
|
|
|
@samp{*} or @samp{D}. The arguments are single characters---do not use
|
|
|
|
@key{RET} to terminate them.
|
1999-09-29 15:17:24 +00:00
|
|
|
|
|
|
|
You can use almost any character as a mark character by means of this
|
2001-03-02 12:27:41 +00:00
|
|
|
command, to distinguish various classes of files. If @var{old-markchar}
|
|
|
|
is a space (@samp{ }), then the command operates on all unmarked files;
|
|
|
|
if @var{new-markchar} is a space, then the command unmarks the files it
|
|
|
|
acts on.
|
1999-09-29 15:17:24 +00:00
|
|
|
|
|
|
|
To illustrate the power of this command, here is how to put @samp{D}
|
|
|
|
flags on all the files that have no marks, while unflagging all those
|
|
|
|
that already have @samp{D} flags:
|
|
|
|
|
|
|
|
@example
|
|
|
|
* c D t * c SPC D * c t SPC
|
|
|
|
@end example
|
|
|
|
|
2001-03-04 07:05:37 +00:00
|
|
|
This assumes that no files were already marked with @samp{t}.
|

|
|
|
|
@kindex % m @r{(Dired)}
|
|
|
|
@kindex * % @r{(Dired)}
|
|
|
|
Mark (with @samp{*}) all files whose names match the regular expression
|
|
|
|
@var{regexp} (@code{dired-mark-files-regexp}). This command is like
|
|
|
|
@kbd{% d}, except that it marks files with @samp{*} instead of flagging
|
|
|
|
with @samp{D}. @xref{Flagging Many Files}.
|
|
|
|
|
|
|
|
Only the non-directory part of the file name is used in matching. Use
|
|
|
|
@samp{^} and @samp{$} to anchor matches. Exclude subdirectories by
|
|
|
|
hiding them (@pxref{Hiding Subdirectories}).

@cindex finding files containing regexp matches (in Dired)
|
1999-09-29 15:17:24 +00:00
|

Mark (with @samp{*}) all files whose @emph{contents} contain a match for
|
|
|
|
the regular expression @var{regexp}
|
|
|
|
(@code{dired-mark-files-containing-regexp}). This command is like

name.

@item C-_

@kindex C-_ @r{(Dired)}

Undo changes in the Dired buffer, such as adding or removing
|
2001-04-30 13:35:05 +00:00
|
|
|
marks (@code{dired-undo}). @emph{This command does not revert the
|
2001-06-20 10:00:40 +00:00
|
|
|
actual file operations, nor recover lost files!} It just undoes
|
2001-04-30 13:35:05 +00:00
|
|
|
changes in the buffer itself. For example, if used after renaming one
|
|
|
|
or more files, @code{dired-undo} restores the original names, which
|
|
|
|
will get the Dired buffer out of sync with the actual contents of the
|
|
|
|
directory.

@cindex operating on files in Dired
|
|
|
|
|
|
|
|
This section describes the basic Dired commands to operate on one file
|
|
|
|
or several files. All of these commands are capital letters; all of
|
|
|
|
them use the minibuffer, either to read an argument or to ask for
|
|
|
|
confirmation, before they act. All of them give you several ways to
|
|
|
|
specify which files to manipulate:
|
|
|
|
|
|
|
|
@itemize @bullet
|
|
|
|
@item
|
|
|
|
If you give the command a numeric prefix argument @var{n}, it operates
|
|
|
|
on the next @var{n} files, starting with the current file. (If @var{n}
|
|
|
|
is negative, the command operates on the @minus{}@var{n} files preceding
|
|
|
|
the current line.)
|
|
|
|
|
|
|
|
@item
|
|
|
|
Otherwise, if some files are marked with @samp{*}, the command operates
|
|
|
|
on all those files.
|
|
|
|
|
|
|
|
@item
|
|
|
|
Otherwise, the command operates on the current file only.
|
|
|
|
@end itemize

|
@vindex dired-dwim-target
|
|
|
|
@cindex two directories (in Dired)
|
|
|
|
Commands which ask for a destination directory, such as those which
|
|
|
|
copy and rename files or create links for them, try to guess the default
|
|
|
|
target directory for the operation. Normally, they suggest the Dired
|
|
|
|
buffer's default directory, but if the variable @code{dired-dwim-target}
|
|
|
|
is non-@code{nil}, and if there is another Dired buffer displayed in the
|
|
|
|
next window, that other buffer's directory is suggested instead.
|
|
|
|
|
1999-09-29 15:17:24 +00:00
|
|
|
Here are the file-manipulating commands that operate on files in this
|
|
|
|
way. (Some other Dired commands, such as @kbd{!} and the @samp{%}
|
|
|
|
commands, also use these conventions to decide which files to work on.)

1999-09-29 15:17:24 +00:00
|
|
|
@item C @var{new} @key{RET}
|
|
|
|
Copy the specified files (@code{dired-do-copy}). The argument @var{new}
|
|
|
|
is the directory to copy into, or (if copying a single file) the new
|
|
|
|
name.
|
|
|
|
|
|
|
|
@vindex dired-copy-preserve-time
|
|
|
|
If @code{dired-copy-preserve-time} is non-@code{nil}, then copying with
|
|
|
|
this command sets the modification time of the new file to be the same
|
|
|
|
as that of the old file.
|

|
2001-02-17 16:43:14 +00:00
|
|
|
@vindex dired-recursive-copies
|
|
|
|
The variable @code{dired-recursive-copies} controls whether
|
|
|
|
directories are copied recursively. The default is to not copy
|
|
|
|
recursively, which means that directories cannot be copied.

@item D

@findex dired-do-delete
|
|

@kindex D @r{(Dired)}
|
|
|
|
Delete the specified files (@code{dired-do-delete}). Like the other
|
|
|
|
commands in this section, this command operates on the @emph{marked}
|
|
|
|
files, or the next @var{n} files. By contrast, @kbd{x}
|
2001-04-26 00:29:21 +00:00
|
|
|
(@code{dired-do-flagged-delete}) deletes all @dfn{flagged} files.

@item R @var{new} @key{RET}
|
|

|
|
@var{new} is the directory to rename into, or (if renaming a single
|
|
|
|
file) the new name.
|
|
|
|
|
|
|
|
Dired automatically changes the visited file name of buffers associated
|
|
|
|
with renamed files so that they refer to the new names.

|
|
|
The Dired command @kbd{!} (@code{dired-do-shell-command}) reads a shell
|
1999-09-29 15:17:24 +00:00
|
|
|
command string in the minibuffer and runs that shell command on all the
|
2001-03-02 12:27:41 +00:00
|
|
|
specified files. @kbd{X} is a synonym for @kbd{!}. You can specify the
|
|
|
|
files to operate on in the usual ways for Dired commands
|
|
|
|
(@pxref{Operating on Files}). There are two ways of applying a shell
|
|
|
|
command to multiple files:
|
1999-09-29 15:17:24 +00:00
|
|
|
|
|
|
|
@itemize @bullet
|
|
|
|
@item
|
|
|
|
If you use @samp{*} in the shell command, then it runs just once, with
|
|
|
|
the list of file names substituted for the @samp{*}. The order of file
|
|
|
|
names is the order of appearance in the Dired buffer.
|
|
|
|
|
|
|
|
Thus, @kbd{! tar cf foo.tar * @key{RET}} runs @code{tar} on the entire
|
|
|
|
list of file names, putting them into one tar file @file{foo.tar}.
|
|
|
|
|
|
|
|
@item
|
|
|
|
If the command string doesn't contain @samp{*}, then it runs once
|
|
|
|
@emph{for each file}, with the file name added at the end.
|
|
|
|
|
|
|
|
For example, @kbd{! uudecode @key{RET}} runs @code{uudecode} on each
|
|
|
|
file.
|
|
|
|
@end itemize
|
|
|
|
|
2001-02-17 16:43:14 +00:00
|
|
|
What if you want to run the shell command once for each file, with the
|
|
|
|
file name inserted in the middle? You can use @samp{?} in the command
|
|
|
|
instead of @samp{*}. The current file name is substituted for
|
|
|
|
@samp{?}. You can use @samp{?} more than once. For instance, here is
|
|
|
|
how to uuencode each file, making the output file name by appending
|
|
|
|
@samp{.uu} to the input file name:
|
1999-09-29 15:17:24 +00:00
|
|
|
|
|
|
|
@example
|
2001-02-17 16:43:14 +00:00
|
|
|
uuencode ? ? > ?.uu
|
1999-09-29 15:17:24 +00:00
|
|
|
@end example
|
|
|
|
|
2001-02-17 16:43:14 +00:00
|
|
|
To use the file names in a more complicated fashion, you can use a
|
|
|
|
shell loop. For example, this shell command is another way to
|
|
|
|
uuencode each file:
|
|
|
|
|
|
|
|
@example
|
2001-04-26 00:29:21 +00:00
|
|
|
for file in *; do uuencode "$file" "$file" >"$file".uu; done
|
2001-02-17 16:43:14 +00:00
|
|
|
@end example
|
2000-01-05 23:47:15 +00:00
|
|
|
|
1999-09-29 15:17:24 +00:00
|
|
|
The working directory for the shell command is the top-level directory
|
|
|
|
of the Dired buffer.
|
|
|
|
|
|
|
|
The @kbd{!} command does not attempt to update the Dired buffer to show
|
|
|
|
new or modified files, because it doesn't really understand shell
|
|
|
|
commands, and does not know what files the shell command changed. Use
|
|
|
|
the @kbd{g} command to update the Dired buffer (@pxref{Dired
|
|
|
|
Updating}).

@section Transforming File Names in Dired
|

|

2001-04-30 13:35:05 +00:00
|
|
|
This section describes Dired commands which alter file names in a
|
|
|
|
systematic way.
|
|
|
|
|
|
|
|
Like the basic Dired file-manipulation commands (@pxref{Operating on
|
|
|
|
Files}), the commands described here operate either on the next
|
|
|
|
@var{n} files, or on all files marked with @samp{*}, or on the current
|
|
|
|
file. (To mark files, use the commands described in @ref{Marks vs
|
|
|
|
Flags}.)
|
|
|
|
|
|
|
|
All of the commands described in this section work
|
|
|
|
@emph{interactively}: they ask you to confirm the operation for each
|
|
|
|
candidate file. Thus, you can select more files than you actually
|
|
|
|
need to operate on (e.g., with a regexp that matches many files), and
|
|
|
|
then refine the selection by typing @kbd{y} or @kbd{n} when the
|
|
|
|
command prompts for confirmation.

|

@kindex % S @r{(Dired)}
|
|
|
|
@findex dired-do-symlink-regexp
|
|
|
|
These four commands rename, copy, make hard links and make soft links,
|
|
|
|
in each case computing the new name by regular-expression substitution
|
|
|
|
from the name of the old file.
|
|
|
|
@end table
|
|
|
|
|
|
|
|
The four regular-expression substitution commands effectively perform
|
|
|
|
a search-and-replace on the selected file names in the Dired buffer.
|
|
|
|
They read two arguments: a regular expression @var{from}, and a
|
|
|
|
substitution pattern @var{to}.
|
|
|
|
|
|
|
|
The commands match each ``old'' file name against the regular
|
|
|
|
expression @var{from}, and then replace the matching part with @var{to}.
|
|
|
|
You can use @samp{\&} and @samp{\@var{digit}} in @var{to} to refer to
|
|
|
|
all or part of what the pattern matched in the old file name, as in
|
|
|
|
@code{replace-regexp} (@pxref{Regexp Replace}). If the regular expression
|
|
|
|
matches more than once in a file name, only the first match is replaced.
|
|
|
|
|
|
|
|
For example, @kbd{% R ^.*$ @key{RET} x-\& @key{RET}} renames each
|
|
|
|
selected file by prepending @samp{x-} to its name. The inverse of this,
|
|
|
|
removing @samp{x-} from the front of each file name, is also possible:
|
|
|
|
one method is @kbd{% R ^x-\(.*\)$ @key{RET} \1 @key{RET}}; another is
|
|
|
|
@kbd{% R ^x- @key{RET} @key{RET}}. (Use @samp{^} and @samp{$} to anchor
|
|
|
|
matches that should span the whole filename.)
|
|
|
|
|
|
|
|
Normally, the replacement process does not consider the files'
|
|
|
|
directory names; it operates on the file name within the directory. If
|
|
|
|
you specify a numeric argument of zero, then replacement affects the
|
2001-04-30 13:35:05 +00:00
|
|
|
entire absolute file name including directory name. (Non-zero
|
|
|
|
argument specifies the number of files to operate on.)
|
1999-09-29 15:17:24 +00:00
|
|
|
|
|
|
|
Often you will want to select the set of files to operate on using the
|
|
|
|
same @var{regexp} that you will use to operate on them. To do this,
|
|
|
|
mark those files with @kbd{% m @var{regexp} @key{RET}}, then use the
|
|
|
|
same regular expression in the command to operate on the files. To make
|
|
|
|
this easier, the @kbd{%} commands to operate on files use the last
|
|
|
|
regular expression specified in any @kbd{%} command as a default.

Compare the current file (the file at point) with another file (the file
|
|
|
|
at the mark) using the @code{diff} program (@code{dired-diff}). The
|
|
|
|
file at the mark is the first argument of @code{diff}, and the file at
|
2001-05-03 07:58:04 +00:00
|
|
|
point is the second argument. Use @kbd{C-@key{SPC}}
|
|
|
|
(@code{set-mark-command}) to set the mark at the first file's line
|
|
|
|
(@pxref{Setting Mark}), since @code{dired-diff} ignores the files marked
|
|
|
|
with the Dired's @kbd{m} command.

Compare the current file with its latest backup file
|

(@code{dired-backup-diff}). If the current file is itself a backup,
|
|
|

compare it with the file it is a backup of; this way, you can compare
|
|
|
|
a file with any backup version of your choice.
|
|
|

|
|

The backup file is the first file given to @code{diff}.

A Dired buffer displays just one directory in the normal case;
|
|
|
|
but you can optionally include its subdirectories as well.
|
|
|
|
|
|
|
|
The simplest way to include multiple directories in one Dired buffer is
|
|
|
|
to specify the options @samp{-lR} for running @code{ls}. (If you give a
|
|
|
|
numeric argument when you run Dired, then you can specify these options
|
|
|
|
in the minibuffer.) That produces a recursive directory listing showing
|
|
|
|
all subdirectories at all levels.
|
|
|
|
|
|
|
|
But usually all the subdirectories are too many; usually you will
|
|
|
|
prefer to include specific subdirectories only. You can do this with
|
|
|
|
the @kbd{i} command:
|
|
|
|
|
|
|
|
@table @kbd
|
|
|
|
@findex dired-maybe-insert-subdir
|
|
|
|
@kindex i @r{(Dired)}
|
|
|
|
@item i
|
|
|
|
@cindex inserted subdirectory (Dired)
|
|
|
|
@cindex in-situ subdirectory (Dired)
|
|
|
|
Insert the contents of a subdirectory later in the buffer.
|
|
|
|
@end table
|
|
|
|
|
|
|
|
Use the @kbd{i} (@code{dired-maybe-insert-subdir}) command on a line
|
|
|
|
that describes a file which is a directory. It inserts the contents of
|
|
|
|
that directory into the same Dired buffer, and moves there. Inserted
|
|
|
|
subdirectory contents follow the top-level directory of the Dired
|
|
|
|
buffer, just as they do in @samp{ls -lR} output.
|
|
|
|
|
|
|
|
If the subdirectory's contents are already present in the buffer, the
|
|

@kbd{i} command just moves to it.
|
|
|
|
|
|
|
|
In either case, @kbd{i} sets the Emacs mark before moving, so @kbd{C-u
|
|
|
|
C-@key{SPC}} takes you back to the old position in the buffer (the line
|
|
|
|
describing that subdirectory).

Use the @kbd{l} command (@code{dired-do-redisplay}) to update the
|
2001-03-02 12:27:41 +00:00
|
|
|
subdirectory's contents. Use @kbd{C-u k} on the subdirectory header
|
|
|
|
line to delete the subdirectory. @xref{Dired Updating}.

@cindex hiding in Dired (Dired)

@dfn{Hiding} a subdirectory means to make it invisible, except for its

@findex dired-hide-subdir

|
|
|
|
Hide or reveal the subdirectory that point is in, and move point to the
|
|
|
|
next subdirectory (@code{dired-hide-subdir}). A numeric argument serves
|
|
|
|
as a repeat count.

@item M-$
|
|
|
|
@findex dired-hide-all

@kindex M-$ @r{(Dired)}
|
|
|
|
Hide all subdirectories in this Dired buffer, leaving only their header
|
|
|
|
lines (@code{dired-hide-all}). Or, if any subdirectory is currently
|
|
|
|
hidden, make all subdirectories visible again. You can use this command
|
|
|
|
to get an overview in very deep directory trees or to move quickly to
|
|
|
|
subdirectories far away.
|
|
|
|
@end table
|
|
|
|
|
|
|
|
Ordinary Dired commands never consider files inside a hidden
|
|
|
|
subdirectory. For example, the commands to operate on marked files
|
|
|
|
ignore files in hidden directories even if they are marked. Thus you
|
|
|
|
can use hiding to temporarily exclude subdirectories from operations
|
|
|
|
without having to remove the markers.
|
|
|
|
|
|
|
|
The subdirectory hiding commands toggle; that is, they hide what was
|
|
|
|
visible, and show what was hidden.

This section describes commands to update the Dired buffer to reflect
|
|
|
|
outside (non-Dired) changes in the directories and files, and to delete

part of the Dired buffer.
|
|
|
|
|
|
|
|
@table @kbd
|
|
|
|
@item g
|
|
|
|
Update the entire contents of the Dired buffer (@code{revert-buffer}).
|
|
|
|
|
|
|
|
@item l
|
|
|
|
Update the specified files (@code{dired-do-redisplay}).
|
|
|
|
|
|
|
|
@item k
|
|
|
|
Delete the specified @emph{file lines}---not the files, just the lines
|
|
|
|
(@code{dired-do-kill-lines}).
|
|
|
|
|
|
|
|
@item s
|
|
|
|
Toggle between alphabetical order and date/time order
|
|
|
|
(@code{dired-sort-toggle-or-edit}).
|
|
|
|
|
|
|
|
@item C-u s @var{switches} @key{RET}
|
|
|
|
Refresh the Dired buffer using @var{switches} as
|
|
|
|
@code{dired-listing-switches}.
|
|
|
|
@end table
|
|
|
|
|
|
|
|
@kindex g @r{(Dired)}
|
|
|
|
@findex revert-buffer @r{(Dired)}
|
|
|
|
Type @kbd{g} (@code{revert-buffer}) to update the contents of the
|
|
|
|
Dired buffer, based on changes in the files and directories listed.
|
|
|
|
This preserves all marks except for those on files that have vanished.
|
|
|
|
Hidden subdirectories are updated but remain hidden.
|
|
|
|
|
|
|
|
@kindex l @r{(Dired)}
|
|
|
|
@findex dired-do-redisplay
|
|
|
|
To update only some of the files, type @kbd{l}
|
2001-04-26 00:29:21 +00:00
|
|
|
(@code{dired-do-redisplay}). Like the Dired file-operating commands,
|
|
|
|
this command operates on the next @var{n} files (or previous
|
|
|
|
@minus{}@var{n} files), or on the marked files if any, or on the
|
|
|
|
current file. Updating the files means reading their current status,
|
|
|
|
then updating their lines in the buffer to indicate that status.
|
1999-09-29 15:17:24 +00:00
|
|
|
|
|
|
|
If you use @kbd{l} on a subdirectory header line, it updates the
|
|
|
|
contents of the corresponding subdirectory.
|
|
|
|
|
|
|
|
@kindex k @r{(Dired)}
|
|
|
|
@findex dired-do-kill-lines
|
2001-04-26 00:29:21 +00:00
|
|
|
To delete the specified @emph{file lines} from the buffer---not
|
|
|
|
delete the files---type @kbd{k} (@code{dired-do-kill-lines}). Like
|
|
|
|
the file-operating commands, this command operates on the next @var{n}
|
|
|
|
files, or on the marked files if any; but it does not operate on the
|
|
|
|
current file as a last resort.
|
1999-09-29 15:17:24 +00:00
|
|
|
|
|
|
|
If you kill the line for a file that is a directory, the directory's
|
|
|
|
contents are also deleted from the buffer. Typing @kbd{C-u k} on the
|
|
|
|
header line for a subdirectory is another way to delete a subdirectory
|
|
|
|
from the Dired buffer.
|
|
|
|
|
|
|
|
The @kbd{g} command brings back any individual lines that you have
|
|
|
|
killed in this way, but not subdirectories---you must use @kbd{i} to
|
2001-04-26 00:29:21 +00:00
|
|
|
reinsert a subdirectory.

@cindex sorting Dired buffer
|
|
|
|
@kindex s @r{(Dired)}
|
|
|
|
@findex dired-sort-toggle-or-edit
|
|
|
|
The files in a Dired buffers are normally listed in alphabetical order
|
|
|
|
by file names. Alternatively Dired can sort them by date/time. The
|
|
|
|
Dired command @kbd{s} (@code{dired-sort-toggle-or-edit}) switches
|
|
|
|
between these two sorting modes. The mode line in a Dired buffer
|
|
|
|
indicates which way it is currently sorted---by name, or by date.
|
|
|
|
|
|
|
|
@kbd{C-u s @var{switches} @key{RET}} lets you specify a new value for
|
|
|
|
@code{dired-listing-switches}.
|
|
|
|
|
|
|
|
@node Dired and Find
|
|
|
|
@section Dired and @code{find}
|
|
|
|
@cindex @code{find} and Dired
|
|
|
|
|
|
|
|
You can select a set of files for display in a Dired buffer more
|
|
|
|
flexibly by using the @code{find} utility to choose the files.
|
|
|
|
|
|
|
|
@findex find-name-dired
|
|
|
|
To search for files with names matching a wildcard pattern use
|
|
|
|
@kbd{M-x find-name-dired}. It reads arguments @var{directory} and
|
|
|
|
@var{pattern}, and chooses all the files in @var{directory} or its
|
|
|
|
subdirectories whose individual names match @var{pattern}.
|
|
|
|
|
|
|
|
The files thus chosen are displayed in a Dired buffer in which the
|
|
|
|
ordinary Dired commands are available.
|
|
|
|
|
|
|
|
@findex find-grep-dired
|
|
|
|
If you want to test the contents of files, rather than their names,
|
|
|
|
use @kbd{M-x find-grep-dired}. This command reads two minibuffer
|
|
|
|
arguments, @var{directory} and @var{regexp}; it chooses all the files in
|
|
|
|
@var{directory} or its subdirectories that contain a match for
|
|
|
|
@var{regexp}. It works by running the programs @code{find} and
|
|
|
|
@code{grep}. See also @kbd{M-x grep-find}, in @ref{Compilation}.
|
|
|
|
Remember to write the regular expression for @code{grep}, not for Emacs.
|
2001-01-04 17:47:11 +00:00
|
|
|
(An alternative method of showing files whose contents match a given
|
|
|
|
regexp is the @kbd{% g @var{regexp}} command, see @ref{Marks vs Flags}.)

|
|
|
|
|
|
|
@findex find-dired
|
|
|
|
The most general command in this series is @kbd{M-x find-dired}, which
|
|
|
|
lets you specify any condition that @code{find} can test. It takes two
|
|
|
|
minibuffer arguments, @var{directory} and @var{find-args}; it runs
|
|
|
|
@code{find} in @var{directory}, passing @var{find-args} to tell
|
|
|
|
@code{find} what condition to test. To use this command, you need to
|
|
|
|
know how to use @code{find}.

2001-06-20 10:00:40 +00:00
|
|
|
@kbd{M-x locate} provides a similar interface to the @code{locate}
|
2001-06-22 21:45:48 +00:00
|
|
|
program. @kbd{M-x locate-with-filter} is similar, but keeps only lines
|
2001-06-20 10:00:40 +00:00
|
|
|
matching a given regular expression.

|
|
|
@vindex find-ls-option
|
|
|
|
The format of listing produced by these commands is controlled by the
|
|
|
|
variable @code{find-ls-option}, whose default value specifies using
|
|
|
|
options @samp{-ld} for @code{ls}. If your listings are corrupted, you
|
|
|
|
may need to change the value of this variable.
