A directory is a kind of file that contains other files entered under various names. Directories are a feature of the file system.
Emacs can list the names of the files in a directory as a Lisp list,
or display the names in a buffer using the
ls shell command. In
the latter case, it can optionally display information about each file,
depending on the options passed to the
This function returns a list of the names of the files in the directory directory. By default, the list is in alphabetical order.
If full-name is non-
nil, the function returns the files' absolute file names. Otherwise, it returns the names relative to the specified directory.
If match-regexp is non-
nil, this function returns only those file names that contain a match for that regular expression—the other file names are excluded from the list. On case-insensitive filesystems, the regular expression matching is case-insensitive.
If nosort is non-
directory-filesdoes not sort the list, so you get the file names in no particular order. Use this if you want the utmost possible speed and don't care what order the files are processed in. If the order of processing is visible to the user, then the user will probably be happier if you do sort the names.(directory-files "~lewis") ⇒ ("#foo#" "#foo.el#" "." ".." "dired-mods.el" "files.texi" "files.texi.~1~")
An error is signaled if directory is not the name of a directory that can be read.
Return all files under directory whose names match regexp. This function searches the specified directory and its sub-directories, recursively, for files whose basenames (i.e., without the leading directories) match the specified regexp, and returns a list of the absolute file names of the matching files (see absolute file names). The file names are returned in depth-first order, meaning that files in some sub-directory are returned before the files in its parent directory. In addition, matching files found in each subdirectory are sorted alphabetically by their basenames. By default, directories whose names match regexp are omitted from the list, but if the optional argument include-directories is non-
nil, they are included.
This is similar to
directory-filesin deciding which files to report on and how to report their names. However, instead of returning a list of file names, it returns for each file a list
), where attributes is what
file-attributesreturns for that file. The optional argument id-format has the same meaning as the corresponding argument to
file-attributes(see Definition of file-attributes).
This function expands the wildcard pattern pattern, returning a list of file names that match it.
If pattern is written as an absolute file name, the values are absolute also.
If pattern is written as a relative file name, it is interpreted relative to the current default directory. The file names returned are normally also relative to the current default directory. However, if full is non-
nil, they are absolute.
This function inserts (in the current buffer) a directory listing for directory file, formatted with
lsaccording to switches. It leaves point after the inserted text. switches may be a string of options, or a list of strings representing individual options.
The argument file may be either a directory or a file specification including wildcard characters. If wildcard is non-
nil, that means treat file as a file specification with wildcards.
If full-directory-p is non-
nil, that means the directory listing is expected to show the full contents of a directory. You should specify
twhen file is a directory and switches do not contain ‘-d’. (The ‘-d’ option to
lssays to describe a directory itself as a file, rather than showing its contents.)
On most systems, this function works by running a directory listing program whose name is in the variable
insert-directory-program. If wildcard is non-
nil, it also runs the shell specified by
shell-file-name, to expand the wildcards.
MS-DOS and MS-Windows systems usually lack the standard Unix program
ls, so this function emulates the standard Unix program
lswith Lisp code.
As a technical detail, when switches contains the long ‘--dired’ option,
insert-directorytreats it specially, for the sake of dired. However, the normally equivalent short ‘-D’ option is just passed on to
insert-directory-program, as any other option.
