dpkg -l / truncation of names

[Rakotomandimby Mihamina <mihamina.rakotomandimby@etu.univ-orleans.fr>]

Hi,
I would like to save the names of all the installed packages.

# dpkg -l | awk '{print $2}'

Does the work, but some packages with long names are name truncated.
What's the option to provide to display the full name?

Thank you.
