查找忽略文件系统循环的跟踪链接

Question

当我尝试查找链接到 /tmp 文件夹的所有文件/目录时，我尝试

ls -di /tmp 

这给了我索引4194305节点/tmp

现在我会找到链接到该索引节点的所有文件

find / -follow -path /media -prune -inum $(ls -di /tmp |cut -d" " -f1)

但这会给我数千个文件系统循环检测到的警告：

我如何忽略这些错误？

Answer 1

这些循环是显示内核数据结构和设备的sysfs伪文件系统的一部分。如果您只是寻找常规文件，您可能不想陷入其中（或/proc就此而言）。

您可以使用-prune子树，就像您从搜索中删除它一样，因为它不太可能包含指向 的/sys链接。使用，您还可以阻止从一个文件系统移动到另一个文件系统，但由于符号链接可以跨文件系统，因此您需要在命令行上单独列出所有文件系统。也就是说，类似/media/tmp-xdevfind

find -L / /home /tmp -xdev -inum $inodenum

/假设您除了、/home和 之外没有其他文件系统/tmp。这也应该消除修剪的需要/media，因为那里的东西可能是单独的安装座。
