Bitburner Server purchasing bot

READ ME

This is a bot which will:

- Buy servers of RAM you specify (default is half your home RAM, minimum of 32gb)

- Upload and execute a script of your choosing

- Template for uploading additional scripts of your choosing (ie. if your main script calls 3x scripts like mine does)

- If you have max servers (25) and they are weak (<25% of your home RAM) and have sufficient money to upgrade, it will prompt a yes/no box to upgrade them. This deletes and rebuys.

Due to the logic inside, it is quite hefty at 13.3gb of RAM required, as such it is not really suited for very early game.

There is some basic technical knowledge required to change a few lines of code to suit your setup. Read the how to carefully.

You can force a server rebuy by running it with the 'f' argument (ie. "run servers.js f")

Main Code And How To

How to use:- terminal > nano "servers.js"

- paste the below code in

- EDIT THE CODE - Line 13 + Lines 45-50

- - Line 13: Change "breaker.js" to whatever your main script filename is that you would like to execute on the remote server.

- - Lines 45-50: If you want to upload more scripts, then amend these lines as well, if you do not need them, then delete between the lines. Note that these will not auto-execute, they assume that your main script calls them. If you need to execute them as well, then add extra lines of

ns.exec("yourScriptNameHere.js", hostname, 1); - save

- terminal > run servers.js

Note: If you do not name the file servers.js, then you amend line 70 to whatever you name the file, or the rebuy function will not work.
