[-F net/mask][-G net6/mask6]
-h display thismessage #帮助信息
-n don't do hostname lookups #禁用主机解析，即不会出现IP显示域名
-N don't convertport numbers to services #以数字为示端口号，如21端口不会显示成ftp

-mlimit sets the upper limit forthe bandwidth scale
-cconfig file specifies an alternativeconfiguration file
-t use textinterface without ncurses #使用文本模式输出
Sorting orders:
-o2s Sort by first column(2s traffic average) #按2s平均流量列排序
-o10s Sort by second column(10s traffic average) [default] #按10s平均流量列排序
-o40s Sort by third column(40s traffic average) #按50s平均流量列排序
-osource Sort by source address #按源IP列排序
-odestination Sort by destinationaddress #按目的IP列排序
The following options are only available in combination with -t
-snum print one single textoutput afer num seconds, then quit #指定刷新几次。
-Lnum number of lines to print #显示多少行数据。当程序多流量大时，则要显示行数多些才行。
