Thanks. So really the complaint is just that dpkg -S operates on the
paths of files as packaged, whereas type -p yields canonical paths,
I assume. Interactively, I guess that's another reason I hadn't thought of
for piping dpkg -S unadornedname | less or using apt-file find
likewise piped. As for scripts (other than personal ones), would people
write them to rely on this feature?
Cheers,
David.
