OK. I wrote the script, and it seems to work.

However, I now discover that in the short run at least it's been a waste of
time, due to a long-standing linux USB bug, because of which everything
grinds to a halt when you attempt to copy a large file (<4GB) to a USB
stick. The process seems to hang after about 2.5GB and the machine becomes
barely useable.

dmesg periodically says things like:
usb 1-12: reset high-speed USB device number 9 using xhci_hcd
sd 11:0:0:0: [sdh] FAILED Result: hostbyte=DID_ABORT driverbyte=DRIVER_OK
sd 11:0:0:0: [sdh] CDB: Write(10) 2a 00 01 55 73 28 00 00 f0 00
blk_update_request: I/O error, dev sdh, sector 22377256

There seems to be a workaround that I haven't had time to try yet.  Maybe
the problem will be fixed in 16.04
