Finding where a package is installed

Recently, I faced an issue on a CentOS box where I had to find the location of a package. My application was running on it and I wanted to modify its config. I was unable to pick the config in /etc so I figured it must be in the folder in which the application is installed.

The application was installed as a daemon but it seems the PATH was not updated. I searched in the usual locations of binaries and packages but I could not find it. The only option left for me was to find out where it was installed.

Using the following command showed all the files of the application package.

rpm -ql <my application>

From the list, I could see where my config file was placed during install.
