shell脚本获取本机端口号
来源: 互联网 发布时间：2017-03-29
本文导语: #netstat -tln -----输出如下------- Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:5801 0.0.0.0:* ...
#netstat -tln
-----输出如下-------
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:5801 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:427 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:2544 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:631 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
tcp 0 0 :::22 :::* LISTEN
tcp 0 0 ::1:25 :::* LISTEN
-------------------------
想得到的输出结果如下：
5801,427,5901,111,2544,631,25,22
请问shell语句要怎么写？
