Fix default startup script (#929)

## What are the changes about?

Discussed in !920. Adds fixes to the startup script by removing the array usage (some shells use arrays different/unsupported) and adds stdout_behavior Inherit flag to the child process to propagate the echos to the TTY.

## What existing issue does this resolve?

N/A

## Pre-requisites

- [x] I have tested & confirmed the changes work locally
