Hi,

I am using logstash to annonymize my logfiles and output them as new logfile using logstash's file output.

My output config looks like this:

```
output
{
	file
	{
		codec => line { format => "%{customerNameFP} %{userNameFP} %{sessionId} %{logTime} de_de - %{processingTime}%{payload}"}
		path => "q:/useractions_anonymous.log"
	}
}

```

But my output looks like this:

```
918826505 1302784860 1x1a111111 1x1 1x1d1 1x1 02.12.2017 23:00:01 de_de - 0.0 DB_LWDR_LIST: XSQL-Filter: 'LWDR_ID IN (xxx)', [NO SORT], 0...END (PageSize: INFINITE), , Fetched: 1, 15 ms, ok.

1376897975 31820156 1x1a11111d 1x1 1x1e1 1x1 02.12.2017 23:00:02 de_de - 0.0 DB_TMLIST: XSQL-Filter: 'TM_ID IN (xxx)', [NO SORT], 0...END (PageSize: INFINITE), , Fetched: 1, 16 ms, , VALUES ==> 0...END (PageSize: INFINITE), , Fetched: 3, 0 ms, *OK*

```

How can I get rid of the empty lines between each correct line?  
Using logstash 6.1.2 in this case.

Thanks, Andreas

found it.  
checking my output with notepad++ and I saw an additional at the end of my lines.  
Seems if it came with my last field I added. At least it works now when I do a gsub over my payload field:  
**replace \r with ""**
