我想完全放弃某个提交。
我做了这个实验:
初始化回购
bash-3.2$ git init
Initialized empty Git repository in /Users/*****/test/.git/
创建文件
bash-3.2$ touch readme
bash-3.2$ ls
readme
提交此创作
bash-3.2$ git add .
bash-3.2$ git commit -m "first commit"
[master (root-commit) b9f8e60] first commit
1 file changed, 0 insertions(+), 0 deletions(-)
create mode 100644 readme
编辑该文件(发生了一些错误)
bash-3.2$ echo WrongMsg > readme
bash-3.2$ cat readme
WrongMsg
不小心提交修改
bash-3.2$ git add .
bash-3.2$ git commit -m "careless commit"
[master 1eec681] careless commit
1 file changed, 1 insertion(+)
检查日志
bash-3.2$ git log --oneline
将给出
1eec681 careless commit
b9f8e60 first commit
现在,我意识到了这个错误,想要解决它
bash-3.2$ git rebase -i HEAD^
会提示
pick 1eec681 careless commit
# Rebase b9f8e60..1eec681 onto b9f8e60 (1 command)
#
# Commands:
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending
# s, squash = use commit, but meld into previous commit
# f, fixup = like "squash", but discard this commit's log message
# x, exec = run command (the rest of the line) using shell
# d, drop = remove commit
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out
将pick
更改为drop
,然后将:wq
更改为保存,然后输出
Successfully rebased and updated refs/heads/master.
检查日志
bash-3.2$ git log --oneline
b9f8e60 first commit
纠正错误
bash-3.2$ echo CorrectMsg > readme
bash-3.2$ cat readme
CorrectMsg
提交
bash-3.2$ git add .
bash-3.2$ git commit -m "correction"
[master f224289] correction
1 file changed, 1 insertion(+)
日志
bash-3.2$ git log --oneline
f224289 correction
b9f8e60 first commit
似乎drop是成功的,但是如果我执行它:
bash-3.2$ git reset --hard 1eec681
HEAD is now at 1eec681 careless commit
bash-3.2$ git log --oneline
1eec681 careless commit
b9f8e60 first commit
BANG,历史仍然在回购中的某个地方,并没有真正被删除。
我可以完全删除这段历史吗?
答案 0 :(得分:4)
git是懒惰的,所有这些提交都会保留,你可以使用
查看它们git reflog
这将显示您所做的所有历史记录更改(Move branch,commit,rebase等)
他们确实得到了垃圾收集器的清理,但老实说这个功能更有帮助,令人讨厌。对于它将使用的微小空间我不会担心它。

最终会被删除但如果您确实需要删除提交,则可以手动运行git gc
您需要使用--aggressive
和--prune=all
运行它才能确保删除悬空提交。
答案 2 :(得分:0)
键入 git reflog 以显示各种提交消息和头号。 输入 git reset --hard HEAD {Head Number goes in here} 。头编号是您希望项目恢复的位置。警告:一旦恢复,您就无法回到那个时间点。
