/ 中的奇怪数据文件

几个月来，我的 / 目录中有一个奇怪的数据文件。它名为tmpUGy0UNqBDAN8BRg_iwbGcvv6S .w62on1kHPb4UtBeezebArfjiGrbJLSdyO6MX7tz_qUyFLz53UZaMWRN lpdzIu2UE.x60v9p.Cn76hktF6QUZGOGZjz7NVBK8_Evh1dx4SscgBeLo5TtXqErwZWC7ma9QvACMaKLoI2 y5d7urc3LsKrUk4zoPjrL71aMEWfCXWMdqJ8YQUgVh1vdPYLhkA-0I-lga5zSe7eIaSZS8bm0Xdm8tV2N 1z。它的所有者是 root。less表示它是一个二进制文件。以下是ls和 的file输出。

看起来有人忘记在某些参数中添加“/”：文件以开头，/tmp所以我现在假设它是目录“/tmp”。

除此之外：像这样的文件/tmp是正常的，并且是用于跟踪用户会话的临时文件。

  • 12 月 30 日已经是很久以前的事了，所以我怀疑你还记不清当时安装了什么。“bleachbit” 使用这种文件名，但可能性不大。
  • 使用“cat -v”检查文件的内容，看看是否可以找到生成这些文件的软件的名称。
