github小记（一）：清除github在add或者commit之后缓存区

---

前言

github自用

一般github上代码提交顺序：

第一步：

git add .
or
git add home/.../.../file_name
or
git add home/.../.../file_name -f
1
2
3
4
5

第二步：

git commit -m "test..."
1

第三步：

git push
1

1. 第一步之后想要撤销

使用git reset .命令

效果展示：

xxxxxx@server:~/xxxxxx/test_rm_cache$ git add test/1rrr.txt -f
xxxxxx@server:~/xxxxxx/test_rm_cache$ git status
On branch main
Your branch is up-to-date with 'origin/main'.

Changes to be committed:
  (use "git restore --staged ..." to unstage)
      new file:   test/1rrr.txt

xxxxxx@server:~/xxxxxx/test_rm_cache$ git reset .
xxxxxx@server:~/xxxxxx/test_rm_cache$ git status
On branch main
Your branch is up-to-date with 'origin/main'.

nothing to commit, working tree clean
