Options:
-a period       Sets the length in seconds of the time window for average
                calculation.
                平均计算时间长度
                Default is 300.
-i max_scaling  Specifies the 100% mark in kBit/s of the graph indicating the
                incoming bandwidth usage. Ignored if max_scaling is 0 or the
                switch -m is given.
                指定入口流量最大值 单位是kBit/s
                Default is 10240.
-m              Show multiple devices at a time; no traffic graphs.
                同时显示多个设备统计信息
-o max_scaling  Same as -i but for the graph indicating the outgoing bandwidth
                usage.
                和-i相同，但是是出口流量
                Default is 10240.
-t interval     Determines the refresh interval of the display in milliseconds.
                刷新间隔
                Default is 500.
-u h|b|k|m|g    Sets the type of unit used for the display of traffic numbers.
   H|B|K|M|G    h: auto, b: Bit/s, k: kBit/s, m: MBit/s etc.
                H: auto, B: Byte/s, K: kByte/s, M: MByte/s etc.
                显示单位
                Default is h.
-U h|b|k|m|g    Same as -u, but for a total amount of data (without "/s").
   H|B|K|M|G    Default is H.
                和-u相同，但是为总流量
devices         Network devices to use.
                指定网卡

--help
-h              Print this help.

example: nload -t 200 -i 1024 -o 128 -U M

The options above can also be changed at run time by pressing the 'F2' key.
运行时使用F2可以查看此页
