我正在阅读的联机帮助unzip
,并遇到了以下问题
-P password
use password to decrypt encrypted zipfile entries (if any). THIS
IS INSECURE! Many multi-user operating systems provide ways for
any user to see the current command line of any other user; even on
stand-alone systems there is always the threat of over-the-shoulder
peeking.
虽然不采用明文形式输入密码(并使其最终出现在外壳程序历史记录中)的安全预防措施当然是正确的,但我发现很难相信有些操作系统可以让其他用户看到其他任何命令行用户。有人可以给我一个例子(包括旧系统)吗?
我相信ps
,top
等等是UNIX的答案。
