The example also shows the use of the -n switch, which prints numeric host addresses, thereby avoiding name lookup and resolution and speeding up the trace.
这个示例还演示-n选项的用途，它输出数字的主机地址，从而避免名称查询和解析，可以提高跟踪速度。
Run "/usr/bin/uname -n" and check if the host name is correct for the system.
运行“/usr/bin/uname –n”，并检查主机名称对系统来说是否正确。
The -n switch specifies that host name-to-IP address resolution shouldn't be performed.
n选项指定不应该执行主机名到ip地址解析。
