方法一:
1.先通過git reflog找到上一次的歷史提交記錄id,git如果沒有特意設置,是會保存記錄一段時間的(a few days or a month)
2.git reset --hard [id]
方法二:
git reset --hard HEAD@{1}
直接回到剛才的那個結點,{}中表示的是結點的序號
方法一的例子如下:
$ git init
Initialized empty Git repository in .git/
$ echo "testing reset" > file1
$ git add file1
$ git commit -m 'added file1'
Created initial commit 1a75c1d: added file1
1 files changed, 1 insertions(+), 0 deletions(-)
create mode 100644 file1
$ echo "added new file" > file2
$ git add file2
$ git commit -m 'added file2'
Created commit f6e5064: added file2
1 files changed, 1 insertions(+), 0 deletions(-)
create mode 100644 file2
$ git reset --hard HEAD^
HEAD is now at 1a75c1d... added file1
$ cat file2
cat: file2: No such file or directory
$ git reflog
1a75c1d... HEAD@{0}: reset --hard HEAD^: updating HEAD
f6e5064... HEAD@{1}: commit: added file2
$ git reset --hard f6e5064
HEAD is now at f6e5064... added file2
$ cat file2
added new file
