remove unwanted file from git repo after using git add . and gitignore

# # I just ran into this after initializing a Visual Studio project _before_ adding a .gitignore file (like an idiot). # # I felt real dumb commiting a bunch of files I didn't need to, so the commands below should do the trick. The first two commands # # came from the second answer on this post: http://stackoverflow.com/questions/7527982/applying-gitignore-to-committed-files # See the unwanted files: git ls-files -ci --exclude-standard # Remove the unwanted files: git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached # Commit changes git commit -am " Removed unwanted files marked in .gitignore " # Push reference : https://gist.github.com/jeffjohnson9046/80bc182db7ae2f4a6150
