Subdirectories in Dired
=======================
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 `-lR' for running `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 `i' command:
`i'
Insert the contents of a subdirectory later in the buffer.
Use the `i' (`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 `ls -lR' output.
If the subdirectory's contents are already present in the buffer, the
`i' command just moves to it.
In either case, `i' sets the Emacs mark before moving, so `C-u
C-<SPC>' takes you back to the old position in the buffer (the line
describing that subdirectory).
Use the `l' command (`dired-do-redisplay') to update the
subdirectory's contents. Use `C-u k' on the subdirectory header line
to delete the subdirectory. Note:Dired Updating.
