我提取交换机端口光功率生成txt文件，其内容如下：
GigabitEthernet1/0/0 current state : UP
Rx Power: -4.85dBm, Tx Power: -4.99dBm
GigabitEthernet1/0/1 current state : UP
Rx Power: -5.73dBm, Tx Power: -5.27dBm
GigabitEthernet1/0/2 current state : UP
Rx Power: -4.93dBm, Tx Power: -4.94dBm
GigabitEthernet1/0/3 current state : UP
Rx Power: -4.17dBm, Tx Power: -4.99dBm
GigabitEthernet1/0/4 current state : UP
Rx Power: -5.23dBm, Tx Power: -5.07dBm
我想生成如下格式的txt文件，各位高手应该怎么写？谢谢哈
GigabitEthernet1/0/1 Rx Power: -5.73dBm
GigabitEthernet1/0/2 Rx Power: -4.93dBm
GigabitEthernet1/0/3 Rx Power: -4.17dBm
GigabitEthernet1/0/4 Rx Power: -5.23dBm

再请教一下如果字符串中还存在pos这个关键字我如何提取啊？
GigabitEthernet1/0/3 current state : UP
Rx Power: -4.17dBm, Tx Power: -4.99dBm
GigabitEthernet1/0/4 current state : UP
Rx Power: -5.23dBm, Tx Power: -5.07dBm
Pos1/0/1 current state : UP
Rx Power: -5.25dBm, Tx Power: -4.26dBm
生成结果为：
GigabitEthernet1/0/3 Rx Power: -4.17dBm
GigabitEthernet1/0/4 Rx Power: -5.23dBm
Pos1/0/1 Rx Power: -5.25dBm
