Bitburner – Advanced Auto Farm Script

Inspired by this basic auto farm, automate all servers with improved performances.

Notice

Note: Require at least 8.1G on your ‘home’ server.

Create a ‘runner.js’ file on your home server, paste the content below on it then run it.

nano runner.js

By default, this script will not kill all other services running on each server. You can enforce it by running

run runner.js --kill

This script will use all your personally owned servers. The more you have, the more it’ll be efficient.

Advanced Usage

You can see all options in-game with

run runner.js --help

You are allowed to use your own hack, grow, weaken script. You can also customize the waiting time between each server. Warning. Always use more that 1ms or you’ll freeze your game.
