U can try "man" for clarifiying with commands.just do:
^^ also remember "." files are hidden files as "$" files in DOS.and in Linux/UNIX-like only small letters(so no Mv) are used and SPACE must be btwn each command options(for eg: "mv <SPACE> -i) .even folders can be hidden using this way.
I think u need to see *tldp.org and *www.linuxcommand.org/
^ Hope that helps.also if ur new to Linux,let me remind u,ur not getting the privilages with newer Linux distros(Debian,Ubuntu,Fedora etc) running this ancient one.
