我在单行中有以下数据。

输入

pid:1230 received at date 12/1/15 17:00:00:230,message ID:1200,Field1:anil,Field3:kumar,Field4:nitin,Field5:Rajat,Field6:Yogesh,Field7:Kishore,Field8:satya,pid:1230 sent message at date 12/1/15 17:00:00:232,message ID:1200,name1:anil,name3:kumar,name4:nitin,name5:Rajat,name6:Yogesh,name7:Kishore,name8:satya,pid:1230 Received message at date 12/1/15 17:00:00:232,message ID:1200,nkd1:anil,nkd3:kumar,nkd4:nitin,nkd5:Rajat,nkd6:Yogesh,nkd7:Kishore,nkd8:satya,pid:1230 sent at date 12/1/15 17:00:00:232,message ID:1200,Field1:anil,Field3:kumar,Field4:nitin,Field5:Rajat,Field6:Yogesh,Field7:Kishore,Field8:satya,pid:1230 received at date 12/1/15 17:00:00:230,message ID:1200,Field1:anil,Field3:kumar,Field4:nitin,Field5:Rajat,Field6:Yogesh,Field7:Kishore,Field8:satya,pid:1230 sent message at date 12/1/15 17:00:00:232,message ID:1200,name1:anil,name3:kumar,name4:nitin,name5:Rajat,name6:Yogesh,name7:Kishore,name8:satya,pid:1230 Received message at date 12/1/15 17:00:00:232,message ID:1200,nkd1:anil,nkd3:kumar,nkd4:nitin,nkd5:Rajat,nkd6:Yogesh,nkd7:Kishore,nkd8:satya,pid:1230 sent at date 12/1/15 17:00:00:232,message ID:1200,Field1:anil,Field3:kumar,Field4:nitin,Field5:Rajat,Field6:Yogesh,Field7:Kishore,Field8:satya

我想将单行分成多行。如果该字段包含“收到于”，那么我想拆分为换行符。上面的单行可以分成两行。

预期输出:

pid:1230 received at date 12/1/15 17:00:00:230,message ID:1200,Field1:anil,Field3:kumar,Field4:nitin,Field5:Rajat,Field6:Yogesh,Field7:Kishore,Field8:satya,pid:1230 sent message at date 12/1/15 17:00:00:232,message ID:1200,name1:anil,name3:kumar,name4:nitin,name5:Rajat,name6:Yogesh,name7:Kishore,name8:satya,pid:1230 Received message at date 12/1/15 17:00:00:232,message ID:1200,nkd1:anil,nkd3:kumar,nkd4:nitin,nkd5:Rajat,nkd6:Yogesh,nkd7:Kishore,nkd8:satya,pid:1230 sent at date 12/1/15 17:00:00:232,message ID:1200,Field1:anil,Field3:kumar,Field4:nitin,Field5:Rajat,Field6:Yogesh,Field7:Kishore,Field8:satya

你能帮我一下吗？谢谢。
