You can add the following code to your .bashrc or .bashprofile (depending on whether you have your term set to open as a login shell or not.). I have it set to show the userame@host: path $ currentcommand, but you can alter the last echo -ne line to just show the command if you wish by deleting the ${USER}@${HOSTNAME}: ${PWD} \$ part, and leaving just echo -ne "\033]0;${BASH_COMMAND}\007"

case "$TERM" in
xterm*|rxvt*|screen*)
    PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"'

    # Show the currently running command in the terminal title:
    # http://www.davidpashley.com/articles/xterm-titles-with-bash.html
    show_command_in_title_bar()
    {
        case "$BASH_COMMAND" in
            *\033]0*)
                # The command is trying to set the title bar as well;
                # this is most likely the execution of $PROMPT_COMMAND.
                # In any case nested escapes confuse the terminal, so don't
                # output them.
                ;;
            *)
                echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD} \$ ${BASH_COMMAND}\007"
                ;;
        esac
    }
    trap show_command_in_title_bar DEBUG
    ;;
*)
    ;;
esac
