Deleting a folder that contains symlinks
提问by user358829
If I rm -rfa folder that has soft links in it, will it try to follow those links and delete the corresponding folder, or will it simply unlink them?
如果我rm -rf的文件夹中有软链接，它会尝试跟随这些链接并删除相应的文件夹，还是只是取消链接？
I have a copy of my home directory with symbolic links in it, and I'm scared to rm -rfit in case it follows those links and blows up the corresponding folders...
我有一个我的主目录的副本，里面有符号链接，我很害怕rm -rf它会跟随这些链接并炸毁相应的文件夹......

Generally speaking, rmdoesn't "delete". It "unlinks". This means that references to a file are removed by rm. When the number of references reaches zero, the file will no longer be accessible and in time, the area of disk where it resides will be used for something else.
一般来说，rm不会“删除”。它“取消链接”。这意味着对文件的引用被删除rm。当引用数达到零时，文件将不再可访问，并且及时，它所在的磁盘区域将用于其他用途。
When you rma directory, the stuff inside the directory is unlinked. Symbolic links are (sort of like) files with the name of their targets inside them and so they're just removed. To actually figure out what they're pointing to and then unlink the target is special work and so will not be done by a generic tool.
当你rm是一个目录时，目录中的东西是未链接的。符号链接是（有点像）文件，其中包含目标名称，因此它们只是被删除。真正弄清楚它们指向什么然后取消链接目标是特殊的工作，因此不会由通用工具完成。

No. rm -rf won't follow symbolic links - it will simply remove them.
不。 rm -rf 不会跟随符号链接 - 它只会删除它们。
% mkdir a
% touch a/foo
% mkdir b
% ln -s a b/a
% rm -rf b
% ls a
foo
