git上传的文件超过100M，如何删除后继续上传

今天在整理自己的文档时，就想着传到git上，以后编辑的时候来回方便，就不需要考虑文档不一致的问题了，然后把自己写的文档都传到git上，发现上传的时候有一个压缩文件一直上传不了，原来是github有限制，针对100M以上的单个文件不允许上传需要修改上传大小设置，因为文件也不是很重要，就想着删除后在继续上传，但是还是抱错，这里记录一下解决方法：

报错信息

利用git push进行上传文件，出现异常，抱错信息如下：

[wolf@wulaoer.org 🔥🔥🔥🔥 wulaoer ]$ git push

大致意思是上传的文档是350MB，超过了最大100MB的限制，因为我这里不想要了就把CV文件删除掉，然后重新push，还是报上面的错误。下面看看如何解决的。

解决方法

首先需要把上次提交记录找出来，这里使用了rev-list找出所有的记录，并使用grep筛选出关键词。

[wolf@wulaoer.org 🔥🔥🔥🔥 wulaoer ]$ git rev-list --objects --all | gre
p "CV"
dccd504e9102a569051d1e3a9b9b0583535fbdd0 python/CV.rar

然后把提交记录删除掉，然后重新提交即可。

[wolf@wulaoer.org 🔥🔥🔥🔥 wulaoer ]$ git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch python/CV.rar' --prune-empty --tag-name-filter cat -- --all

这里用到几个命令汇总一下。

# 删除original文件夹
rm -rf .git/refs/original/
# 修剪旧的reflog条目
git reflog expire --expire=now --all
# 验证数据库中对象的连接性和有效性
git fsck --full --unreachable
# 打包解压缩的对象。 删除冗余的对象
git repack -A -d
# 清理不必要的文件并优化本地存储库
git gc --aggressive --prune=now
# 强制推送到远程git仓库
$ git push origin --force --all

也有说利用git log找到记录，然后使用git rebase删除记录，然后刷新重新提及即可，但是我这里试了一下，第一个文件的时候可以，但是我删除第二个大文件的时候就不行了，所以这里就不记录了，没有了，看看其他的吧。
