使用Mac 未安装BFG。想先了解Git Filter-Branch
问题：我已经能够从我的Git Repos中删除一些文件（其他文件似乎并不想删除），但是，每次我获取文件删除回购增加时尺寸。这不是我想要做的。我觉得Github在某处保存了一些东西，但我不确定如何定位它。
我想做什么：删除文件和历史记录（缩小回购邮件大小）。
我已经按照此处的步骤开始清理文件并以Push the Repository结束。我一直在定位随机文件，以便更好地了解如何删除文件。我一直在当地的仓库工作，然后在GitHub上推进遥控器。
我认为这似乎是在正确的轨道上
rm -rf .git / refs / original / 这似乎没有做任何事情
git reflog expire --expire = now --all 这似乎没有做任何事情
git gc --prune = now
5.git gc --aggressive --prune = now
7.git push origin --force --tags（未在下面的代码中显示）
Patricks-Air:github-gem PatCosta$ git filter-branch --tag-name-filter cat --index-filter 'git rm -r --cached --ignore-unmatch manifest' --prune-empty -f -- --all
