recover files deleted in Emacs on Ubuntu

[funny.haha]

Dear All,

I am running GNU emacs version 22.2.1 on Ubuntu. When I am in DIRED 
mode, I can delete files by pressing SHIFT+D. My question is that: can I 
recover the deleted files in case of a mistake?

Obviously, the file is not in the Trash Can of Ubuntu. One work around 
is to associate "dired-recursive-delete' with perhaps some customized 
command that moves the file to the transh can. Does any one know how to 
do this?

Thank you for any pointer.
