Remove the Packages completely leaving no file? [duplicate]

Question

I have uninstalled a package and i have added the ppa via terminal for example.

I have to know that the packages have uninstalled successfully without leaving any file in my computer.

Is there any Command line to check it whether it was removed without leaving a single file?

I'm using Ubuntu14.04

Answer 1

If the package maintainer is a good package maintainer, then the following should be enough:

To remove a package completely, use

 sudo apt-get purge package_name

But it can be, that some configuration files exists in your home folder. This files will not be removed by the command above.

As I don't know your package name, simply start a search

find ~ -maxdepth 1 -iname '*package_name*''

And

find ~/.config -iname '*package_name*''

Don't remove the * from the search pattern. Change only the package_name.

But if you in doubt, start a full scan

sudo   find / -iname '*package_name*''
