I think the point is you don't need cat at all. Why not use
grep movie_name dvd-list.txt

Sure but you ain't got very structured data, doesn't handle
input of data very well and you haven't got referential integrity
etc.

What you have is a fine way of dealing with lightly structured
data which doesn't require a lot of data entry - especially
when you add in use of awk and sed. It isn't a direct replacement
for the applications I would use a database for, and vice-versa.
