Symbolic Link (符号链接,亦即是快捷方式)相对于 hard link , Symbolic link 可就好理解多了,基本上, Symbolic link 就是在创建一个独立的文件,而这个文件会让数据的读取指向他 link 的那个文件的档名!由于只是利用文件来做为指向的动作, 所以,当来源档被删除之后,symbolic link 的文件会『开不了』, 会一直说...

(One common mistake people make when setting the permissions of directories is to accidentally remove the execute permission when using absolute modes.) 目录也有权限。 如果目录可读,你可以列出目录的内容;但只有当目录可执行时,你才能访问目录中的文件。 (设置目录权限时,人们常犯的一个错误是在使用绝对...

2.17.2 Symbolic Links(符号链接) A symbolic link is a file that points to another file or a directory, effectively creating an alias (like a shortcut in Windows). Symbolic links offer quick access to obscure directory paths. 符号链接是一个指向另一个文件或目录的文件,实际上创建了一个别名(类似...

$ su user2 -c 'readlink -v "/home/user1/links/user1_symlink"' readlink: /home/user1/links/user1_symlink: Permission denied We don’t have the correct permissions to access the symbolic link, so let’s try adding execute permissions to the directories in its path. Then we can re...
