## -----------------------------=[ WARNING ]=-------------------------------- ##

# This script is now woefully out of date due to which accounts ESXi allows to
# ssh into the box as well as sticky folders/file flags.
# I've since ported the whole thing to python with a lot of bells and whistles
# and if i get around to making it public, i'll put a link here.

"You got your markdown in my shell script!" "No, you got your shell script in my markdown!"

Mixed Markdown and Shell Scripting

: By the power of this magic string: ex: set ft=markdown ;:<<'```shell' #, this file is now both a markdown document and an executable shell script. chmod +x it and try running it!

The above line does just what it says. More specifically, when placed within in the first 5 lines and preceded only by blank lines or #-prefixed markdown headers:

  1. The first part of the magic string makes github and various editors (e.g. atom with the vim-modeline packge) treat the file as having markdown syntax (even if the file doesn't have an extension)
  2. The second part (if run in a shell), makes the shell skip execution until it encounters the next ```shell block.

(The line also has to start with a : so that it's valid shell code.)

How to passthrough SATA drives directly on VMWare ESXI 6.5 as RDMs

How to passthrough SATA drives directly on VMWare EXSI 6.5 as RDMs

There aren't many tutorials about this, the only tutorials I've found were about passing through entire PCIe cards to VMs, or refered to old ESXI versions (below 6.5) that used a more comprehensive desktop client instead of the web app. In v6.5, the web app was introduced and the desktop client was deprecated. You used to be able to setup RDMs in the desktop client, but with the introduction of the web console, this is no longer the case. This tutorial shows you how to pass SATA HDDs to the virtual machine on VMWare ESXI 6.5. This tutorial is partially based on VMWare's own KB and the now deprecated Forza IT blog post.

A word about VMWare ESXI 6.7

There is now an option while editing your VM's settings to add a New raw disk when you click `Add ha
