AC.7 Operating on Files

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:

• If you give the command a numeric prefix argument n, it operates on the next n files, starting with the current file. (If n is negative, the command operates on the -n files preceding the current line.)
• Otherwise, if some files are marked with `*', the command operates on all those files.
• Otherwise, the command operates on the current file only.

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 dired-dwim-target is non-nil, and if there is another Dired buffer displayed in the next window, that other buffer's directory is suggested instead.

Here are the file-manipulating commands that operate on files in this way. (Some other Dired commands, such as ! and the `%' commands, also use these conventions to decide which files to work on.)

C new RET

Copy the specified files (dired-do-copy). The argument new is the directory to copy into, or (if copying a single file) the new name.

If dired-copy-preserve-time is non-nil, then copying with this command sets the modification time of the new file to be the same as that of the old file.

The variable dired-recursive-copies controls whether directories are copied recursively. The default is to not copy recursively, which means that directories cannot be copied.

D

Delete the specified files (dired-do-delete). Like the other commands in this section, this command operates on the marked files, or the next n files. By contrast, x (dired-do-flagged-delete) deletes all flagged files.

R new RET

Rename the specified files (dired-do-rename). The argument 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.

H new RET

Make hard links to the specified files (dired-do-hardlink). The argument new is the directory to make the links in, or (if making just one link) the name to give the link.

S new RET

Make symbolic links to the specified files (dired-do-symlink). The argument new is the directory to make the links in, or (if making just one link) the name to give the link.

M modespec RET

Change the mode (also called "permission bits") of the specified files (dired-do-chmod). This uses the chmod program, so modespec can be any argument that chmod can handle.

G newgroup RET

Change the group of the specified files to newgroup (dired-do-chgrp).

O newowner RET

Change the owner of the specified files to newowner (dired-do-chown). (On most systems, only the superuser can do this.)

The variable dired-chown-program specifies the name of the program to use to do the work (different systems put chown in different places).

P command RET

Print the specified files (dired-do-print). You must specify the command to print them with, but the minibuffer starts out with a suitable guess made using the variables lpr-command and lpr-switches (the same variables that lpr-buffer uses; @pxref{Hardcopy}).

Z

Compress the specified files (dired-do-compress). If the file appears to be a compressed file already, it is uncompressed instead.

L

Load the specified Emacs Lisp files (dired-do-load). @xref{Lisp Libraries}.

B

Byte compile the specified Emacs Lisp files (dired-do-byte-compile). See (elisp)Byte Compilation section `Byte Compilation' in The Emacs Lisp Reference Manual.

A regexp RET

Search all the specified files for the regular expression regexp (dired-do-search).

This command is a variant of tags-search. The search stops at the first match it finds; use M-, to resume the search and find the next match. See section Searching and Replacing with Tags Tables.

Q regexp RET to RET

Perform query-replace-regexp on each of the specified files, replacing matches for regexp with the string to (dired-do-query-replace-regexp).

This command is a variant of tags-query-replace. If you exit the query replace loop, you can use M-, to resume the scan and replace more matches. See section Searching and Replacing with Tags Tables.

One special file-operation command is + (dired-create-directory). This command reads a directory name and creates the directory if it does not already exist.
