I have never seen any there, only within the users actual home directory (/home/user), and the command he gives will handle all of those. It is important when doing something like this to make sure all the possibilities are covered so another way to do it and verify everything was copied could be: # cp -a /home/* /home/.[!.]* <dest/directory> In this command it explicitly asks for anything beginning with a '.', but since both '.' and '..' match they need to be excluded, thus the [!.] (not dot) part. For clarity read up on regexps. Tim's recommendation is (I believe) actually a better command. # cd /home # cp -a . <dest/directory> This form of the command will handle even the .xxx files in the current directory properly. > I've written a similar instruction, without any comments though.
