For example, on my system: > $ dpkg -S bin/javac > openjdk-8-jdk-headless:amd64: /usr/lib/jvm/java-8-openjdk-amd64/bin And then assuming that you have configured deb-src URLs in your sources.list, just retrieve the sources for the binary package that contains the binary you're interested in: > $ apt-get source openjdk-8-jdk-headless > Reading package lists...

Or, if you don't want to download the sources, jump to https://tracker.debian.org/ and enter the package name of interest that was returned by "dpkg -S". In this case, you'll be redirected to https://tracker.debian.org/pkg/openjdk-8, which shows you both the source and resulting binary packages. There are probably multiple other slicker ways to do it than what I just posted, but maybe that helps get you started. Cheers, tony
