as MsMittens say rm could be quite dangerous ...
So you can use the alias command to help you :

nn@cool ]$ alias rm="rm -i" (it's remove interactively, so ask for removing a file )

and if you want to pass the interactive command do (after an alias) rm -f ... (seriously dangerous !!!) => force removing !!!

if you know what is a .profile or .bashrc (if you use bash of course) then put the alias in it so you have this alias after all your logg in ...
if you like the colors try a usefull

nn@cool ]$ alias ls="ls -lA --color" (It works for Linux and well made *nix but not for HP-UX)

so all your files will be displayed in color (useful do make a quick distinction between folder/file/exe/links etc...
See you soon
PS: please feel free to ask me some question about *nix (and more linux)
