remove unneeded configuration files in debian

dpkg-query -l| grep -v "ii " | grep "rc " | awk '{print $2" "}' | tr -d "\n" | xargs aptitude purge -y
This will, for an application that has already been removed but had its configuration left behind, purge that configuration from the system. To test it out first, you can remove the last -y, and it will show you what it will purge without actually doing it. I mean it never hurts to check first, "just in case." ;)

What's the sense in grep -v "ii " | grep "rc "? Somehow this doesn't make any sense at all. grep "^rc " is more than just sufficient. Additionally, aptitude is quite ressource hungy, a simple dpkg -P is more straighter.

Well, I have also found the activities that rest your brain and I will surely try those activities because I am getting bored at home and I use to find unique activities online.

Is legit? I cannot answer positively to this question. The company is very similar to a scam, so you should look for something else. It will be wise.
