I would, but then again not even this is mentioned in the manpage:
-q[=<n>], --quiet[=<n>]
Suppress all incremental progress indicators, thus making the output loggable. This may be supplied multiple times to make the program quieter, but
unlike apt-get, aptitude does not enable -y when -q is supplied more than once.
The optional =<n> may be used to directly set the amount of quietness (for instance, to override a setting in /etc/apt/apt.conf); it causes the program
to behave as if -q had been passed exactly <n> times.
