delete file remind

["Tran Tuan Anh" <trantuan@comp.nus.edu.sg>]

Hi all:

Could anyone tell me how to config the system so that
when I delete a file it will remind me first?

Currently, when I type "rm *.java"
then it just remove all the file.
but I want the shell ask the users to reconfirm the action.

Thanks a lot!
