https://github.com/bitcoin/bitcoin/pull/727 :

This is designed to work nicely with 'gettransaction' and new 'blockhash' information returned in listtransactions; it is modified from the 'getblock' that was in my monitorreceived patch.

getblockhash <index>
Returns hash of block in best-block-chain at <index>.

e.g. getblockhash 0 returns 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f
(genesis block hash)

getblock <hash>
Returns details of a block with given block-hash.

e.g. ./bitcoind getblock $(./bitcoind getblockhash 0) returns the genesis block:

Code:
{
  "hash" : "000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f",
  "blockcount" : 0,
  "version" : 1,
  "merkleroot" : "4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b",
  "time" : 1231006505,
  "nonce" : 2083236893,
  "difficulty" : 1.00000000,
  "tx" : [
    "4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b"
  ],
  "hashnext" : "00000000839a8e6886ab5951d76f411475428afc90947ee320161bbf18eb6048"
}

How often do you get the chance to work on a potentially world-changing project?
