user37851: I tried to use sx, but it no longer works since bip62 (malleability fix). Nodes don't accept generated transactions, saying "high S signature".
What offline command-line tool would be the best?

user38546: There are many command line tools for creating and signing raw transactions offline, most of them written in Python: pycoin, python-bitcoinlib, pybitcointools and others.
If you use Electrum wallet, it has command line tools for offline transaction creation and signing:
$ ./electrum help createrawtx
$ ./electrum help signtransaction
