[Dalton, Barnaby]

To rename files I use a perl script 'rename' from the perl cookbook
http://www.linuxchix.org/pipermail/techtalk/2001-October/012104.html

To replace stuff in files have a look at
http://www.emacswiki.org/cgi-bin/wiki.pl?SearchAndReplaceAcrossMultipleFiles
. I use grep-x which does what you asked with the grep buffer but there are
other options documented here as well.

Again, that only handles part of the use case, which I see having 3
main parts:

0 interactive search/replace for a string within

1 files with names matching another string

2 anywhere in the directory tree below the current directory

So dired-mark-files-regexp allows me to mark the files by name (1), and 
dired-do-query-replace-regexp does the interactive search/replace. But
only find-name-dired (or similar) seems to get me the files desired in
the entire directory tree. 

However that I still need to dired-mark-files-regexp, with '.*', in
order to mark all the files returned by find-name-dired! Is there a
way around that?

Thanks: I documented the find-name-dired/dired-mark-files-regexp
combination there.

Right.

Yes.  As I suggested earlier:


C-x h	; mark-whole-buffer
M-x dired-mark-files-in-region RET

Oops, here's a customization that requires:

(defadvice dired-mark-files-in-region (before interactive activate)
   (interactive "r"))

You could even bind dired-mark-files-in-region to a key in dired-mode-map,
perhaps ". h".
