Delete marked files from dired

I've gotta lotta files to delete before rsyncing to a thumb drive.  I
know how to mark all files in a dir (* s) when in dired mode, but do not know how to
delete all those marked files.  Anybody?  ;)

Press D, for `dired-do-delete'

Not sure how you are marking them, ... but if you use the d key and
them the x key you should get prompted if you want to delete the file.

He is marking them with keys * s which is
`dired-mark-subdir-files'. x, or
`dired-do-flagged-delete' doesn't work then (it
does for d, `dired-flag-file-deletion', as you
mention) but perhaps the OP was unaware of that
method as well so why not.

Does somebody remember the story of different marks?

I mean, Dired has D for flagging for deletion, * for marking for most
other operations, and a command to change one mark to another. Ibuffer
has D for killing and > for other operations.

Most other file managers have just one kind of mark and it works the
same way for copying, moving, and deleting.

I wonder how and why that feature evolved?

It is a very useful feature.  You can easily have any
number of different marks, representing _different sets_
of files, and then act on any given set in various ways.

Dired keys that act on marked files typically act on the
files marked `*'.  (Those marked `D' are usually called
"flagged", not just "marked", and only one key, `D', acts
directly on them.)

Changing files marked with `*' to another mark keeps
them marked (keeps that set defined) but removes them
from being acted on (by commands that act on `*'-marked
files, which is the typical case).

Changing another mark back to `*' lets you then act
on its files.  If there are already some other files
marked `*' when you do that then you have effectively
joined those two sets (union).

You get the idea.  It's really pretty simple and quite
visible - you can see the various labeled sets.

It's a bit like using tags in Bookmark+, but only one
mark at a time applies to a given file.

   I wonder how and why that feature evolved?

IIRC (corrections welcome) way beck when, there was only the ‘d’
(key) producing ‘D’ in the left margin.  The other keys, letters
and symbols were a generalization that avoided subsuming ‘d’/‘D’
because such force is uncouth to long-time users' muscle-memory.

I don't remember because I never knew, but there can
be tons of application. For example, one target file
and one source; then hit a key to invoke source on
target (e.g., move a file into a dir or feed indata
from a text file as argument to an executable).

In this case, I suspect it is to separate deletion
from everything else, as a convenience/security
mechanism. Which makes sense!

One counterexample is Gnus, tho not a generic file
manager, in practice is/could be just that with
respect to mail/articles/posts, which are/can be
stored as individual files (depending on backend).

In Gnus, there are tons of markings, even parallel
systems: e.g., one that tells the message have been
opened (or "read"), R, and one that tells it has been
answered, a.

By the way, you can find answer to questions
such as this one with Emacs' `apropos' command.
Do

    M-x apropos RET dired delete RET

and see what you find. For this particular
question `apropos-command' is even better
because what you want to do is do something.

I didn't know about dired-do-delete, but here's another way (more
complicated, but potentially useful for other things).  You probably
know that you can mark files with `D' (for delete) or `*' (for other
things).  You might not know that you can have other marks
(one-character only, I presume), and change them with
`dired-change-marks' (`* c').  So, after marking with `m' (which uses
`*' as the mark), you can type

* c * D x

*c*Dx

This is change the * marks to D marks (D for deletion).  Then execute
(x).

Still, you don't need it with `dired-do-delete'.
Bind it to a key, say D, and you can do

    * s D

With this suggestion, it'd be

    * s * c * D x

I agree with Emanuel's suggestion The "* s D" is quicker.

Also, you do not need to re-map "D".  In Dired "D" is mapped to
dired-do-delete by default.

Come to think of it, perhaps it is good it's
not *too* quick! I once deleted a file
accidentally. It wasn't terribly important,
just complete access to Fort Knox. Still, it
bothered me at the time having lost that
file...

Oh, yeah? And you don't think for such an
important key, setting it up twice can be
a virtue?

I found this:

"You can delete empty directories just like other files, but normally
Dired cannot delete directories that are nonempty. If the variable
dired-recursive-deletes is non-nil, then Dired can delete nonempty
directories including all their contents. That can be somewhat risky."

So, how do I set the above named variable or, better yet, how do I
invoke it w/o changing my emacs config file?  I've got some changes in
my ~/.emacs file, but I don't really understand 'em all.  They were
suggestions by others, much like this Q.  ;)

M-x customize-variable RET dired-recursive-deletes RET

But make sure you really really really want to delete non-empty

The first part of yer solution works, but not the 2nd part.  I get a
response of "[No match]".  Backing up a bit and letting emacs do an

OK, my bad.  Turns out you gotta be IN dired mode fer the variable to
show up.  I used another xterm to put me in an non-dired mode of emacs
and that does NOT work.  Now all I gotta do is learn how the
"customize" screen works.  Thank you.  ;)

Not exactly.  The variable is defined in dired.el, and so is not defined
in Emacs until this file is actually loaded, e.g. by means of (require
'dired) or by using an autoloaded command (e.g. M-x dired, aka C-x d).
You may try putting (require 'dired) in your init.el (or just saying M-:
(require 'dired)) - the variable will be there for you to customize
without starting dired even once.

Might be that the variable is not known to emacs until dired-mode is
actually loaded.

Might be easier to just put

  (setq dired-recursive-deletes 'always)

in your .emacs (maybe accompanied by a comment indicating what this

You could, but "recursive" as in recursion or
recursive descent is a good word to know.

Many of the shell tools has an option to do
whatever recursively, and I'd say drill down
a directory hierarchy is the most common
use case.

Not sure if it is actually easier, but at least it works!  Thank you,

Apparently, "nil" is not acceptable.  I had "t" in there, before.  With
"'always", it always seems to work.  DUH!

It is easier. Make a shortcut to bring up the
config file. Make an edit and re-evaluate the
individual defun (or form). Done.

The more you do it the quicker it'll be because
you will be better and better at Lisp. Which is
a gain in itself.

Only if you do it *too* much you'll start doing
all sorts'a things in Lisp. Then it will be
much, much slower :)

Perhaps new blood in the sense that the old

Ha ha ha! :)

Fortran, "Formula Translation", from IBM in
1957, perhaps the oldest programming language
still in use.

It beats Lisp by a single year!

Fortran tho obviously cannot be compared to
Lisp which is to programming what the
Pythagoras Theorem and unit circle are to
geometry, or what riot gear and a baton are to
a police officer at a peaceful G8 summit...

How about "!rm -rRET" ?

(Also, for large directories it seems much faster than Dired's deletion
mechanism - after all, it's compiled C, not interpreted Lisp;-) - which
for larges sizes trumps the process overhead.)

Try this:

    (setq dired-deletion-confirmer (lambda (x) t))
