Does cp command have any option to overwrite the destination file which is a symbolic link?
cp命令是否有任何选项可以覆盖作为符号链接的目标文件？
The problem is as follows:
问题如下：
[dthnguyen@dthnguyen test]$ ls -l
total 8
-rw-rw-r--. 1 dthnguyen dthnguyen 5 Feb 21 09:07 a.txt
lrwxrwxrwx. 1 dthnguyen dthnguyen 7 Feb 21 08:55 b.txt -> ./a.txt
-rw-rw-r--. 1 dthnguyen dthnguyen 5 Feb 21 08:55 c.txt
[dthnguyen@dthnguyen test]$ cp c.txt b.txt
After do the copy, a.txt has the content of c.txt, b.txt still links to a.txt. The expected result is a.txt holds the old content, b.txt is a new regular file that has the same content as c.txt.
复制完成后，a.txt的内容为c.txt，b.txt仍链接到a.txt。预期的结果是a.txt保存旧内容，b.txt是一个新的常规文件，其内容与c.txt相同。
