The client is now properly initialized. In the rest of this shell
session, you might now run \`tezos-client\` to communicate with a
tezos node launched with \`launch-sandboxed-node $1\`. For instance:

  tezos-client rpc get /chains/main/blocks/head/metadata

Note: if the current protocol version, as reported by the previous
command, is "ProtoGenesisGenesisGenesisGenesisGenesisGenesk612im", you
may have to activate in your "sandboxed network" the same economic
protocol than used by the alphanet by running:

  tezos-activate-alpha

Warning: all the client data will be removed when you close this shell
or if you run this command a second time.

Activate tab completion by running:

  tezos-autocomplete
