Answer 1

For IntelliJ users

When i was trying to git rebase i was getting the following error: 'hint: Waiting for your editor to close the file... code -n -w: code: command not found error: There was a problem with the editor 'code -n -w'.'

The same error showed up when i was trying to associate IntelliJ with Git:

The problem was that I did not have the command code added in my environment PATH variable. And i didn't want to use Visual Studio Code from my terminal. So that is why it prompted "command not found". I solved this by deleting

editor = code -n -w

from the core section in my .gitconfig file. Git worked properly again.
