w可以显示完整的IP地址吗？

  • 772

当我w在 Ubuntu Server 14.04 上使用该命令时，我得到的输出如下所示：

 18:44:24 up 4 days,  3:10,  1 user,  load average: 0.00, 0.00, 0.00
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
kd       pts/0    2001:db8:1334:2c 12:54    0.00s  0.06s  0.00s w

如您所见，IP 地址已被截断。有什么方法可以w显示完整的 IP 地址而不被截断？

14.04

  2. 我相信您的解决方案是使用last -w不会截断主机名的方法。

    要过滤您的结果以查看当前登录的用户，只需简单的操作即可grep。

    last -w | grep "logged in"
