To run the example, you can use ./bin/erc20-current-balance
and it will create a spreadsheet of current balances for a single user, defined in example.txt, for the FUEL token.
Make a file in the same directory, yourfile.txt.
Make it line-delineated list of Ethereum addresses.
Get the contract address of the ERC20 token you want to check.
./bin/erc20-current-balance -contractAddress=ERC20_ADDRESS -file=YOURFILE.TXT
