If you are only interested in packages which no longer have *any* files
on the filesystem, then compare the output of the following two
commands:
pkg_info -qL package | wc -l
pkg_info -qg package | wc -l
If the output of those two commands is the same, then there are no valid
package files left at all, and a pkg_delete -f is in order.
Moreover, if you are only interested in the existence of the files, it
would be easier to do something like:
remove=3D1
pkg_info -qL package | while read fname; do
[ -f "$fname" ] && remove=3D0
done
if [ $remove =3D=3D "1" ]; then pkg_delete package; fi
G'luck,
Peter
