方法1

删除当前路径下属主为root的所有文件和文件夹

find ./* -user root -print0 | xargs -0 rm -rf

删除当前路径下属组为root的所有文件和文件夹

find ./* -group root -print0 | xargs -0 rm -rf

为了防止删错，开始时最好分步执行命令，当确定该删时才合并执行：

# 第一步
ls -l

# 第二步：
find ./* -user root

# 第三步：
find ./* -user root -print0

# 第四步：合并命令正式执行删除操作
find ./* -user root -print0 | xargs -0 rm -rf

方法2: 不要轻易执行rm -rf删除操作，若删除就后悔莫及了

find ./* -user root -exec ls -l {} +
find ./* -user root -exec rm -rf {} +

方法3：此方法不可靠，容易删错文件
