cygwin是否了解NTFS连接点？ [英] Does cygwin understand NTFS junction points?

问题描述

cygwin（1.7.x）是否了解Windows NTFS连接点（由Win7 / 2008或sysinternals的junction.exe中的mklink创建）？

Does cygwin (1.7.x) understand Windows NTFS junction points (as created by mklink in Win7/2008 or sysinternals' junction.exe)?

不同于由ln -s创建的符号链接？

How do they differ from a symbolic link as created by "ln -s "?

推荐答案

是的，Cygwin 1.7了解NTFS连接点， NTFS符号链接（与Vista一起引入）。它们显示为Cygwin程序的符号链接，因此，例如删除此类链接将只删除链接而不是指向的文件。

Yes, Cygwin 1.7 does understand NTFS junction points and also NTFS symbolic links (as introduced with Vista). They appear as symbolic links to Cygwin programs, so that for example deleting such a link will only delete the link rather than the file being pointed too.

Cygwin的原因在创建Cygwin符号链接时不使用NTFS符号链接，只有高级管理员才允许创建它们（除非注册表设置更改），并且没有所有必需的POSIX语义。

The reason that Cygwin doesn't use NTFS symbolic links when creating Cygwin symlinks is that only elevated administrators are allowed to create them (unless a registry setting is changed) and that they don't have all the required POSIX semantics.
