<p>I'm using BDK to create a transaction using <code>bdk-cli</code> interface, researching how to send a Tx I pulled the help for the <code>create_tx</code> command. It's not clear how to create a Tx when you want to send less than the total <code>(-a, --send_all option)</code> of funds from the selected UTXO, it is also not clear how to deal with the change. Does anyone know how to do it, if possible? Thanks for the help.</p>

Since there is nothing special about a change output that distinguishes it from other output I would try multiple `--to` options, one for main recipient and one sending a change amount to an address of yours?

Actually you can probably specify multiple addresses after a single `--to` as suggested by the ellipsis after `--to ...` in the help text you quoted. That seems more likely to work.
