Debain Package rebuild

Question

I've downloaded .deb package

Then I've extracted all the data from the current .deb file and add a new file with arbitrary content.

My question: how can I create a new .deb package from this modified directory /tmp/tcpdump?

Answer 1

Create a necessity directory structure, then:

dpkg-deb --build package_name
