How do I remove CLion-2016.2.3 completely from Ubuntu 16.04 LTS?

Simple Steps are :

1. Delete the clion folder you have downloaded and extracted.
2. Remove cache in ~/. using the command : sudo rm -r ~/.Clion.

Run the following command in terminal to find all the directories and files containing clion in their name :-

$ sudo find . -iname "*clion*"

Then delete the directories and files you have found.

To delete directories/files, go to the location of that directory/file in terminal using cd and run the following command :-

$ sudo rm -rf DIRECTORY_NAME/FILE_NAME

Also need remove settings: /home/user/.config/JetBrains
