Thank you man your videos are actually very good.

why did you choose the `#!/bin/sh` and not `#!bin/bash`? I had to change shell for `.sh` to work(Kali armf). Also, why not use `printf` instead of `echo`?

Anyway I knew nothing about these things 24hours ago, guess your videos did inspire me somehow, to go on a learning crusade. These where a few things that puzzled me a bit :).

Thanks
