How do I show my wallet from the command line?
Direct command-line access via bitcoind is not available any more. You can get access from the command line via the RPC (Remote Procedure Call) API, e.g. with python. The API calls list is found here.

To give a specific example, you can access wallet information via the Python RPC API. Given that the client was booted with rpcuser=user and rpcpassword=pass, the sample python script illustrates how you can call the getbalance command:

  from jsonrpc import ServiceProxy

  access = ServiceProxy("http://user:pass:8332")
  access.getinfo()
  access.listreceivedbyaddress(6)
  print access.getbalance()
