1.1       harris41   19: The following solution works well for me
                     20: on many of my servers.
                     21: 
                     22: 1. cp /etc/profile /etc/profile.orig
                     23: 2. Edit /etc/profile
                     24: 3. diff /etc/profile /etc/profile.orig
                     25: [root@zaphod root]# diff /etc/profile /etc/profile.orig

                     31: < echo "Commands below this line occur after $HISTDATE" >> $HOME/.bash_history

                     39: NOTE: /etc/profile is many times called twice, so there are two

                     41: 
                     42: This is the best solution I have found aside from altering
