If I would like to lock a file as read-only. Even root can not use an editor to modify it, just allowing any program to open it read-only.

Any suggestions?

程序（即使以 root 身份运行）将无法篡改文件。当然，root 可以取消这一点，但大多数程序（尤其是非恶意程序）都无法通过它。

设置它

sudo chattr +i file

您可以使用 Perl 或其他语言来创建文件锁

但是，root 可能会杀死进程以获得对文件的访问权限。
