由于 reflog 中的 sha 相同，无法从 Git 恢复提交

Question

我正在尝试恢复代码，因为我不小心切换到了 eclipse 中的一个分支并以某种方式丢失了所有数据（我仍然不知道我做了什么）。当我在命令行中打开我的 git reflog 时，我看到：

6dc60f6 HEAD@{14}: commit: fixed class mismatch for integers
638fbb1 HEAD@{15}: commit: fixed first NPE bug
22fc2b9 HEAD@{16}: commit: v 6.0.5
0acef4f HEAD@{17}: commit: clean up
8a441cb HEAD@{18}: commit: cleaned up db code
9ac384d HEAD@{19}: commit: ver 6.0.4
ce1f1c2 HEAD@{20}: commit: addded drivers
9b5a4dd HEAD@{21}: checkout: moving from master to 9b5a4dde0f97303579ec0cf15413ecce83a636dc
6dc60f6 HEAD@{22}: commit: change Db
9b5a4dd HEAD@{23}: commit: // for public schema: "" or "public" 
f668dd1 HEAD@{24}: commit: changed schema
a0e5b2a HEAD@{25}: commit: changed frames

我正在尝试结帐6dc60f6 HEAD@{14}: commit: fixed class mismatch for integers，但我所有的尝试都转到6dc60f6 HEAD@{22}: commit: change Db，这是一个更旧的版本。这是来自 git reflog 命令，而不是 git log 所以检查 @{14} 也不起作用。

有没有办法检查6dc60f6 的最新提交，还是丢失了？

谢谢。

附：其他 14 个命令只是我从一个分支切换到另一个分支并再次尝试修复它。

运行git reflog show --no-abbrev，这是在我执行所有那些充斥 reflog 的检查之前，它位于 repo 的 zip 文件中，因此它从 @{0} 开始，注意 2（HEAD，master）具有相同的哈希但不同的提交消息：

Answer 1

解决方法：

gitk --all $( git fsck --no-reflog | awk '/dangling commit/ {print $3}' )

Answer 2

问题是git reflog 将哈希缩写为 7 个字符，但是这两次提交中的前 7 个字符是相同的。

要使用 reflog 获取完整哈希，请使用以下命令：

git reflog show --no-abbrev

然后，您可以使用完整的哈希来检查您想要的提交。
