无法删除损坏的符号链接

Question

我有一个以前指向 Dropbox 目录的符号链接。我不知道我做错了什么，但显然现在它指向了自己。

hyper@mypi:/home/hyper/test$ ls -l
total 1024
lrwxrwxrwx 1 hyper hyper 7 Feb 15  2013 Dropbox -> Dropbox

当我尝试删除链接时，我得到：

hyper@mypi:/home/hyper/test$ rm Dropbox
rm: cannot remove ‘Dropbox’: Not a directory

我还能尝试什么来摆脱这个链接？

strace rm Dropbox 的部分输出：

Answer 1

错误消息不是指符号链接，而是指当前目录！

男人2取消链接：

int unlinkat(int dirfd, const char *pathname, int flags);

错误

伊诺迪尔

路径名是相对的，dirfd 是一个文件描述符，指的是目录以外的文件。

因此，您应该cd至少上一级并查看该目录。它是否已被删除或类似的情况（当它是进程的 CWD 时通常不可能）。
