Re: list installed packages present only in stable

[Jörg-Volker Peetz]

Maybe, this "one-liner" does what you want?

aptitude -F "%p" search ~Astable| sort | \
    (aptitude -F "%p" search ~Aunstable ~Atesting | sort -u | \
     comm -23 --nocheck-order /dev/fd/3 -) 3<&0

All three archives have to be present with the names used above in your
sources.list file (that is, e.g., "unstable" and not "sid").
