I have an array myArray on the geth command line of 1000 elements. When I type myArray on the geth console, it prints to screen. I'd like to pipe this to a text file. My development setup uses testrpc and go-ethereum with analysis of post-scripts in Python.

At the moment I'm cutting and pasting from geth. I sense there may be a much better way of doing it, but can't seem to find an example on searching.

Is there a simple way to save an array to file from the go-ethereum javascript command line?

  • Is there any particular reason you're using the geth console as opposed to nodeJS and web3? The geth console is pretty limited compared Node. – Tjaden Hess Jan 27 '17 at 17:30
  • @TjadenHess force of habit mainly... it has worked ok up to now. – Lee Jan 27 '17 at 17:34

    The geth console is essentially just a stripped-down node console. All your scripts will still work in node, and you can actually use libraries and files. – Tjaden Hess Jan 27 '17 at 17:37
  • @TjadenHess do you happen to know how I'd start node with the equivalent of: geth attach rpc:http://localhost:8545? Thanks – Lee Jan 27 '17 at 18:13

The geth console doesn't seem like the best tool for the job. A better method would be to use NodeJS + web3.

Just follow these instructions to connect web3 to your testrpc, then you can use exactly the same script as before, but write to a file using 

var fs = require('fs');
fs.writeFileSync("myfile.txt", myArray);
