How to see which package a file belongs to

Previously I wrote a post talking about how to see what files were installed as a part of a package. In this post, I'll talk about going to other way i.e. how to tell which package a file belongs to

On Debian/Ubuntu you can do so using the dpkg search function:

# sudo dpkg -S /etc/init.d/whoopsie
whoopsie: /etc/init.d/whoopsie

On RedHat/CentOS you can use the rpm command:

# rpm -qf /usr/bin/bash
