如何检查提交的内容仍然存在

Question

如何验证去年现有提交的内容是否仍然保持不变？我有 10 个具有相同标签的提交，内容可能会丢失或覆盖。现在我需要将当前内容与旧提交相匹配，以验证是否有更改。

比较两个commit/branch，看看是否有任何差异。

$ git fetch
$ git log                           # copy the commit hash
$ git diff HEAD..<commit>           # shows what is in the commit that is not in HEAD   
$ git diff <commit-1> <commit-2>    # diff of two commits
$ git diff <branch-1>..<branch-2>   # diff off two branches
