xfterm4 profile?

[luiX_]

    Hi, I have a question about the terminal used on xfce4... I use to 
work with some aliases such as: ls='ls -la --color' , cp='cp -v' and 
things like that, for using them in the tty I put them in ~/.profile but 
how can I do this with xfterm4, I mean how can I make this aliases 
automatically when I open a xfterm4 terminal?

    Thanks,
    Luis,
