在git管理的項(xiàng)目下， 做一些編譯或者運(yùn)行測試的操作，會產(chǎn)生一些未追蹤的文件Untracked files, 可以使用git clean命令來刪除。

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   info.py

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

no changes added to commit (use "git add" and/or "git commit -a")

$ git clean -nfd
Would remove test/log/
Would remove test/info.txt

$ git clean -fd
Removing test/log/
Removing test/info.txt

• -f： --force， 強(qiáng)制刪除 untracked 文件
• -d：刪除整個文件夾，-fd 強(qiáng)制刪除 untracked 文件和文件夾
• -n： 查看會刪掉哪些文件，防止重要文件被誤刪
