Hello everyone,

I have a lot of .pcap file in one folder (~10,000). I want import this data to elasticsearch.

As I know, flag "-I" can import just one .pcap file at one time.

Is there any way I can do this? Thanks a lot!

@wangyufeng0615 Not out of the box, we mostly use `-I` for development purpose, but you can write a simple shell script to loop through all the files.

Also make sure you use -t, so packetbeat read the file as fast as possible.

```auto
  -t, --t Read packets as fast as possible, without sleeping

```
