About this question
I have a codebase which I want to push to GitHub as open source. In this git-controlled source tree, I have certain configuration files which contain passwords. I made sure not to track this file and I also added it to the .gitignore file. However, I want to be absolutely positive that no sensitive information is going to be pushed, perhaps if something slipped in-between commits or something. I doubt I was careless enough to do this, but I want to be positive.
Is there a way to "grep" all of the git? How to search git history? Is it possible to get every version of every file that ever existed? I guess if there is a command that dumps the diff file for every commit, that might work?
