I have done something like this:
1. git add .
2.git commit
thus commiting a video file of 200mb which i then tried to remove by deleting the video file and repeating step 1 and 2, but that did not helped either, then i tried googling which ended up with running these three commands
1.git add -u
2.git reset HEAD path/to/file
3.git commit
thus i am on 3rd commit, still unable to push as my video file is still somewhere in commit.. what should i do to get out of this mess !
