Rather than have a local node on my PC, I'd like to be able to attach the geth cli console to INFURA and then issue requests within geth's java console, e.g. web3.eth.getBalance(<address>)

I signed up for INFURA and received an email with some endpoints to use, but I am unclear what specific commands I should use so that my geth console attaches to one of those endpoints.

Thanks

I'm afraid you can't connect to a remote host because geth attach works via ipc.

Try this instead:

> npm install web3
> node 
> Web3 = require("web3");
> web3 = new Web3(new Web3.providers.HttpProvider("https://mainnet.infura.io/<your access key>:8545"));
> web3.eth.blockNumber

Update

Since version 1.4 geth attach supports rpc also however it doesn't work for me:

> geth attach https://mainnet.infura.io/<my access key>:8545

    web3.eth.blockNumber does not work, but you can do it asynchronously: web3.eth.getBlockNumber().then(res => console.log(res)) – Lane Rettig Oct 1 '18 at 22:58

The main infura nodes do not support geth attach. Infura maintains legacy nodes that they use for testing that it works for .

geth attach https://gmainnet.infura.io(geth)
or
geth attach https://pmainnet.infura.io (parity)
