Yeah, it's called biff and for some stupid reason, it gets turned on by default. You can get rid of this annoyance as follows. As root, edit /etc/profile and fine the following lines. if [ -x /usr/bin/biff ]; then biff y fi Either delete them, or add a number sign in front of each so that they look like this.\ #if [ -x /usr/bin/biff ]; then # biff y #fi Another way is to put "biff n" as the last line of your .profile or .bash_profile, but since this is an absolutely useless and annoying program, I prefer to disable it systemwide. It is the first thing I do when I install a fresh copy of Slackware.
