git 恢复删除的本地分支

参考博客：https://blog.csdn.net/PersonalM/article/details/108385526

过程比较简单，下面以实验的方式讲解一下：

1 首先创建一个文件夹作为实验文件夹

mkdir test_recover

2 初始化目录

cd test_recover
git init

回显：

[user_name@id ~/c]$ cd test_recover
[user_name@id test_recover]$ git init
Initialized empty Git repository in /pd01/user_name/c/test_recover/.git/

3 创建一个文件并 commit

echo "this is master branch" > 1.txt
git add 1.txt
git commit -m "master add 1.txt"

回显：

[user_name@id test_recover]$ echo "this is master branch" > 1.txt
[user_name@id test_recover]$ git add .
[user_name@id test_recover]$ git commit -m "master add 1.txt"
[master (root-commit) 40bf112] master add 1.txt
 1 files changed, 1 insertions(+), 0 deletions(-)
 create mode 100644 1.txt

4 创建一个分支并添加一个文件并 commit

git checkout -b branch1
echo "branch1 add 2.txt" > 2.txt
git add 2.txt
git commit -m "branch2 add 2.txt"

回显：

[user_name@id test_recover]$ git checkout -b branch1
Switched to a new branch 'branch1'
[user_name@id test_recover]$ echo "branch1 add 2.txt" > 2.txt
[user_name@id test_recover]$ git add 2.txt
[user_name@id test_recover]$ git commit -m "branch2 add 2.txt"
[branch1 a1e927e] branch2 add 2.txt
 1 files changed, 1 insertions(+), 0 deletions(-)
 create mode 100644 2.txt

5 切换到 master 分支并删除 branch1 分支

git checkout master
git branch -l
git branch -D branch1
git branch -l

显示结果：

[user_name@id test_recover]$ git checkout master
Switched to branch 'master'
[user_name@id test_recover]$ git branch -l
  branch1
* master
[user_name@id test_recover]$ git branch -D branch1
Deleted branch branch1 (was a1e927e).
[user_name@id test_recover]$ git branch -l
* master

6 恢复 branch1 分支

git reflog
git checkout -b branch1_recover HEAD@\{1}
git branch -l

显示结果：

[user_name@id test_recover]$ git reflog
65f5e75 HEAD@{0}: checkout: moving from branch1 to master
a1e927e HEAD@{1}: commit: branch2 add 2.txt
65f5e75 HEAD@{2}: checkout: moving from master to branch1
[user_name@id test_recover]$ git checkout -b branch1_recover HEAD@\{1}
Switched to a new branch 'branch1_recover'
[user_name@id test_recover]$ git branch -l
* branch1_recover
  master
