Geth Gananche emulator - set up Geth like Ganache. Geth produces better debugging output for Remix and Truffle Debug.

geth-dev-mode.sh

# cd ~/.geth/

# Add following script here

# Create ~/.geth/keys, ~/geth/dev

# Add keys 0.txt,1.txt..N.txt, and passwords.txt, with each line in passwords.txt representing password for that account

# import into ~/geth/dev: geth account import --datadir ~/.geth/chain ~/.geth/dev/0.txt etc., enter same password

# full command: geth account import --datadir ~/.geth/chain ~/.geth/dev/0.txt && geth account import --datadir ~/.geth/chain ~/.geth/dev/1.txt && geth account import --datadir ~/.geth/chain ~/.geth/dev/2.txt && geth account import --datadir ~/.geth/chain ~/.geth/dev/3.txt && geth account import --datadir ~/.geth/chain ~/.geth/dev/4.txt && geth account import --datadir ~/.geth/chain ~/.geth/dev/5.txt && geth account import --datadir ~/.geth/chain ~/.geth/dev/6.txt && geth account import --datadir ~/.geth/chain ~/.geth/dev/7.txt && geth account import --datadir ~/.geth/chain ~/.geth/dev/8.txt && geth account import --datadir ~/.geth/chain ~/.geth/dev/9.txt

# by default the first account is unlocked with UINT_MAX eth. to fund the remaining accounts, in the internal console, paste this:
# for(var i = 1; i<10; i++){ eth.sendTransaction({from:eth.accounts[0], to:eth.accounts[i], value: web3.toWei(10000, "ether"), gas:100000}); }

# each line works as follows:
# remove old chain
# start geth
# datadir selection
# start RPC
# Remix Desktop 1.2.1 package
# RPC parameters
# Debug symbols
# Dev mode w/ console
# allow account unlock over RPC
# Unlock first 10 accounts
# passwords file (must be relative to current directory)
