I took your sample, and made some changes with my script. Since
it all seemed to be the same date, I moved it to the first lines as a
heading. Also, what kind of terminal are you displaying this in.
Under gnome-terminal, I was able to use
gnome-terminal --geometry=132x24
to make the screen wider to display the text, but you might be
using a terminal window that doesn't allow this option. I've also
used putty in the past with settings of fonts to get more.
