如何知道我是哪种类型的用户?

如何知道我是哪种类型的用户?

在阅读有关 Linux 的文章时,我了解到:: 默认情况下,Linux 区分几种帐户类型,以便隔离processesworkloads。Linux 有四种类型的帐户:

  • 系统

  • 普通的

  • 网络

现在,当我在 shell 上尝试 $last 时,我得到了:

wtmp begins Wed Oct  1 15:18:10 2014

在这里,我只是得到了第二个属性的System Account type对应内容system boot,,我可以获得一些其他命令来与其他帐户类型进行交互吗?即Network,Normal(我想我正在运行它,不是吗?),Root(通过使用 sudo,不是吗?),,最后一行是什么wtmp begins Wed Oct 1 15:18:10 2014意思?

答案1

最后一行 wtmp begins Wed Oct 1 15:18:10 2014 是什么意思?

这意味着您的系统从 2014 年 10 月 1 日星期三 15:18:10 开始写入登录活动的日志记录。

wtmp 是将登录活动写入日志文件的过程。因此,如果您想查看登录活动,那么您可以从 wtmp 开始运行的那一刻开始看到。

欲了解更多信息,您可以查看它的手册页并且 Google 是您的朋友。

希望能帮助到你。
