You could possibly do something with this, which checks each installed
package for files that have been accessed in the last six months. Please
note, however, that it cannot work if you mount your relevant filesystems
with noatime!
for P in $(dpkg -l '*' | awk '/^i/{print $2}')
do
echo -n "Checking $P: " >&2
U=$(
for F in $(dpkg -L "$P")
do
test -f "$F" && find "$F" -atime +180
done 2>/dev/null
)
test -n "$U" && echo "in use" >&2 || echo "MAYBE NOT USED RECENTLY" >&2
done
