I have added stdin { } into the input of my logstash config file. When running it I've been trying to run it with one config file, one call but for 6 files since it is all being ingested into one index. How can I do this in a single call? I want to run each file once only. So:
> /logstash\_run\_path/logstash -f /logstash\_config\_file\_path/logstash\_config\_file \< /file\_\_path/file1
How can I add file2 , file3, file4, etc. to this call?

```
cat file1 file2 file3 | /logstash_run_path/logstash -f /logstash_config_file_path/logstash_config_file
```
