Note that you no longer had to give `signrawtransaction` extra help, because all of that extra information was already in your wallet. Most importantly, you didn't make your private keys vulnerable by directly manipulating them. Instead the process was _exactly_ the same as respending a normal UTXO, except that the transaction wasn't fully signed at the end.

### Sign It On Other Machines
The final step is exporting the partially signed `hex` to any other machines and signing it again:
```
$ signedtx=$(bitcoin-cli -named signrawtransaction hexstring=02000000014ecda61c45f488e35c613a7c4ae26335a8d7bfd0a942f026d0fb1050e744a67d000000009100473044022025decef887fe2e3eb1c4b3edaa155e5755102d1570716f1467bb0b518b777ddf022017e97f8853af8acab4853ccf502213b7ff4cc3bd9502941369905371545de28d0147522102e7356952f4bb1daf475c04b95a2f7e0d9a12cf5b5c48a25b2303783d91849ba421030186d2b55de166389aefe209f508ce1fbd79966d9ac417adef74b7c1b5e0777652aeffffffff0130e1be07000000001976a9148dfbf103e48df7d1993448aa387dc31a2ebd522d88ac00000000 | jq -r '.hex')
