How to uninstall intellij idea on ubuntu 13.10
On a later version this may work:
$ snap remove intellij-idea-community
After trying and searching more, I found that it's very easy and simple. All you have to do to delete the whole Intellij is:
There is a hidden file called .IdeaIC13 in the home directory, it contains two files. Just delete the file.
Delete the installation directory for Intellij, which is usually located at opt/ directory or where you installed it previously.
