0.2 Introduction

Uninstalling a software on a system has long being a headache problem. If you install a software using a package manager like brew, or apt. It is easy. You simply do

# brew
brew remove [package-name]
# use auto remove to remove the dependency
brew autoremove

# apt
apt purge [package-name]
# use auto remove to remove the dependency
apt autoremove

If you install the app using app store. Just uninstall it in the app store.

However, if you install the app by just copy the app into /Applications. Then, simply remove the app itself is clearly not enough. For instance, steam store all the game you download in the '~/Library' folder. If you just remove the app itself, there will be tons of files left.

And there is a app that help us do that. The AppCleaner.
