Gitignore - how to ignore .idea / directory for ruby

Question

I placed .idea / in both my ~/.gitignore_global and my specific .gitignore project (and committed it later), but I still see the file as uninstalled.

How can I ignore these files?

I have done this:

 git config --global core.excludesfile ~/.gitignore_global 

but it did not help.

file name is ok:

 $ ls ~/.gitignore_global /home/durrantm/.gitignore_global 

Answer 1

These files have already been added to the git repository. Do git rm --cached .idea , then commit.

Answer 2

You may also need to run the filter branch to completely destroy the folder of your entire repository. On github you will find convenient documentation for this thing.

Answer 3

Try git update-index --assume-unchanged
