If I have a bulk wallet with, say 100000 key pairs (address/private key) and I have received payments on any, say 1000 of them, how can I sweep all the coins to a new address? It would be even better if I can do it from the command line, for example > sweep keypairs.txt 1Q7nrZ7PGWTtKVkQk1mLZovbJKEfLubXtv and all the available coins are transacted to the destination address. The format is for example:
