Linux find 命令-根据 inode 和设备查找文件？

我想查找具有给定 inode 编号的文件。使用 find-inum并不完全有用，因为它会列出来自每个文件系统/设备的具有 inode 编号的文件。如何将此搜索限制在特定设备/fs 中？

以下没有帮助 -

$ sudo find / -inum 2
/
/dev
/dev/shm
/dev/pts/ptmx

下面确认上面列出的文件来自各种设备

答案1

我倾向于使用sudo debugfs -R 'ncheck {inode}' /dev/{device} 2>/dev/null它应该只列出该设备的文件。

由于您没有指定文件系统：这仅适用于 ext 并且我假设您使用了默认系统。

答案2

从man find：

   -mount Don't descend directories on other filesystems.
          An alternate name for -xdev, for compatibility with
          some other versions of find.
