Output of command.

The signature of my mails was made with the output of these commands:

# cat firma_base_sola; echo -e "\n\tOne day like today:" ; calendar -A
0 -f /usr/share/calendar/calendar.world | head -n 2

And the result (private data part omitted)

.....
One day like today:
Jun 13 Alexander the Great dies (323BC)
Jun 13 Pioneer flies past Neptune, and therefore out of the Solar System

I will change it now. I let the previous one here for if I want to take it
back later or if it's useful for somebody.
