场景：
某一次的commit不小心把大文件传上去了，后面的tag、branch都把这个大文件包含进来了，某一天重新git pull的时候才发现，速度好慢啊，没想到一个仓库竟然一百多M，这时才想把罪魁祸首给删除掉，不仅仅是当前分支，我们还想删除整个仓库中所有包含该文件的记录。
解决：
操作比较复杂，不过基本是无脑操作，只要按照以下步骤来就行了：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
git gc git count-objects -v git verify-pack -v .git/objects/pack/pack-*.idx | sort -k 3 -n | tail -3 git rev-list --objects --all | grep bbbd19a8d4c87677cb0cf64833a5eb1ce4b95e40 git log --pretty=oneline --branches -- tools/analyze_weights_featuremap/aaa.npy git filter-branch --force --index-filter 'git rm -rf --cached --ignore-unmatch tools/analyze_weights_featuremap/aaa.npy' --prune-empty --tag-name-filter cat -- --all git push origin master --force git for-each-ref --format='delete %(refname)' refs/original git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdin git reflog expire --expire=now --all git gc --prune=now git push origin --force --all git push origin --force --tags |
[qgg_green]注意：这样操作之后，其他clone过的仓库都要重新git pull一下。[/qgg_green]
