Ignore files with git locally

Sometimes it's necessary to ignore some files in a repository only locally. For rails developers it's often ./config/database.yml file. Every developer has his own database configuration.

With git it can be easily achieved, we may instruct git no to track changes in certain files:

git update-index --assume-unchanged ./config/database.yml

Next time we type git status the changes in ./config/database.yml won't be shown.

If you think you need to track that file again, just do:

git update-index --no-assume-unchanged ./config/database.yml

(pay attention to --no prefix).

Thanks!
