There is no -retainids when using ltrdigest, Why don't add one?

Hi,

I found that all IDs were changed after running ltrdigest, why don't add -retainids option to retain original IDs like sort and select?

Best,
Kun

Good question, I'll mark this as a feature request :)

In the meantime, you can just set the GT_RETAINIDS environment variable to yes to get the same effect even without the explicit command line option.

Thank you for your reply, export GT_RETAINIDS=yes worked.
