Emacs has commands for performing many other operations on files. All operate on one file; they do not accept wildcard file names.
M-x delete-file prompts for a file and deletes it. If you are
deleting many files in one directory, it may be more convenient to use
Dired rather than
delete-file. See Dired Deletion.
M-x move-file-to-trash moves a file into the system Trash (or Recycle Bin). This is a facility available on most operating systems; files that are moved into the Trash can be brought back later if you change your mind.
By default, Emacs deletion commands do not use the Trash. To
use the Trash (when it is available) for common deletion commands,
change the variable
This affects the commands M-x delete-file and M-x
delete-directory (see Directories), as well as the deletion
commands in Dired (see Dired Deletion). Supplying a prefix
argument to M-x delete-file or M-x delete-directory makes
them delete outright, instead of using the Trash, regardless of
If a file is under version control (see Version Control), you should delete it using M-x vc-delete-file instead of M-x delete-file. See VC Delete/Rename.
M-x copy-file reads the file old and writes a new file named new with the same contents.
M-x copy-directory copies directories, similar to the
cp -r shell command. It prompts for a directory old
and a destination new. If new is an existing directory,
it creates a copy of the old directory and puts it in new.
If new is not an existing directory, it copies all the contents
of old into a new directory named new.
M-x rename-file reads two file names old and new using the minibuffer, then renames file old as new. If the file name new already exists, you must confirm with yes or renaming is not done; this is because renaming causes the old meaning of the name new to be lost. If old and new are on different file systems, the file old is copied and deleted. If the argument new is just a directory name, the real new name is in that directory, with the same non-directory component as old. For example, M-x rename-file RET ~/foo RET /tmp RET renames ~/foo to /tmp/foo. The same rule applies to all the remaining commands in this section. All of them ask for confirmation when the new file name already exists, too.
If a file is under version control (see Version Control), you should rename it using M-x vc-rename-file instead of M-x rename-file. See VC Delete/Rename.
M-x add-name-to-file adds an additional name to an existing file without removing its old name. The new name is created as a hard link to the existing file. The new name must belong on the same file system that the file is on. On MS-Windows, this command works only if the file resides in an NTFS file system. On MS-DOS, it works by copying the file.
M-x make-symbolic-link reads two file names target and linkname, then creates a symbolic link named linkname, which points at target. The effect is that future attempts to open file linkname will refer to whatever file is named target at the time the opening is done, or will get an error if the name target is nonexistent at that time. This command does not expand the argument target, so that it allows you to specify a relative name as the target of the link. On MS-Windows, this command works only on MS Windows Vista and later.
M-x insert-file (also C-x i) inserts a copy of the contents of the specified file into the current buffer at point, leaving point unchanged before the contents. The position after the inserted contents is added to the mark ring, without activating the mark (see Mark Ring).
M-x insert-file-literally is like M-x insert-file, except the file is inserted literally: it is treated as a sequence of ASCII characters with no special encoding or conversion, similar to the M-x find-file-literally command (see Visiting).
M-x write-region is the inverse of M-x insert-file; it
copies the contents of the region into the specified file. M-x
append-to-file adds the text of the region to the end of the
specified file. See Accumulating Text. The variable
write-region-inhibit-fsync applies to these commands, as well
as saving files; see Customize Save.
M-x set-file-modes reads a file name followed by a file
mode, and applies that file mode to the specified file. File modes,
also called file permissions, determine whether a file can be
read, written to, or executed, and by whom. This command reads file
modes using the same symbolic or octal format accepted by the
chmod command; for instance, ‘u+x’ means to add
execution permission for the user who owns the file. It has no effect
on operating systems that do not support file modes.
chmod is a
convenience alias for this function.
