git 如何查看已经跟踪的文件和删除已经跟踪的文件

git 使用 git ls-tree -r master --name-only 查看已经跟踪的文件，使用 git rm --cached filename 删除已经跟踪的文件。

git 查看和删除已经跟踪的操作示例

初始化git仓库

mkdir -p ~/gittest
cd ~/gittest
git init .
echo "hello" > a.txt
git add .
git commit -m 'test'

查看已经跟踪的文件

git ls-tree -r master
100644 blob ce013625030ba8dba906f756967f9e9ca394464a    a.txt

删除已跟踪的文件

git rm --cached a.txt
rm 'a.txt'

git status
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

        deleted:    a.txt

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        a.txt

执行删除后需要执行提交

git commit -m 'delete a.txt'
[master 96ac39e] delete a.txt
 1 file changed, 1 deletion(-)
 delete mode 100644 a.txt

再次查看已经跟踪的文件

git ls-tree -r master
# 结果是空的

git status
On branch master
Untracked files:
  (use "git add <file>..." to include in what will be committed)

        a.txt
