我正在尝试获取命令的输出
iperf -c 10.0.0.1 -t 3600 -i 2
并且只需要列出整个小时的记录的间隔和带宽字段。
我已很多年没有使用过 grep 或 awk 了。
帮助将会非常棒!
示例输出:
------------------------------------------------------------
Client connecting to node2, TCP port 5001
TCP window size: 129 KByte (WARNING: requested 130 KByte)
------------------------------------------------------------
[ 3] local <IP Addr node1> port 2530 connected with <IP Addr node2> port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 19.7 MBytes 15.8 Mbits/sec
期望输出:
0.0-10.0 15.8

如果你正在使用 iperf2,你可能想尝试 -yC 格式化选项
[root@localhost iperf2-code]# src/iperf -c 192.168.1.4 -i 1 -yC -t 5 20180510151943,192.168.1.1,42090,192.168.1.4,5001,3,0.0-1.0,63438848,507510784 20180510151944,192.168.1.1,42090,192.168.1.4,5001,3,1.0-2.0,63569920,508559360 20180510151945,192.168.1.1,42090,192.168.1.4,5001,3,2.0-3.0,57802752,462422016 20180510151946,192.168.1.1,42090,192.168.1.4,5001,3,3.0-4.0,57409536,459276288 20180510151947,192.168.1.1,42090,192.168.1.4,5001,3,4.0-5.0,57016320,456130560 20180510151947,192.168.1.1,42090,192.168.1.4,5001,3,0.0-5.0,299237376,478429304
