Checking Windows Size

This gist is inspired by YASP short video below, https://www.youtube.com/shorts/2UFcAU8nTQs

The intention is to check the numbers of COLUMNS and FILES in a Bash Window Terminal

The goal of the video and this script, it's to emulate an framework similar to Flask or CDK

chroot1.sh is a bash script to create a custom sandbox based on chroot0.sh from book Core Kubernetes. Christopher Love, Jay Vyas.

The script creates a process isolated sandbox using unshare. More information on https://www.manning.com/books/core-kubernetes

	#### Bash does not have a native ternary operator. Instead, the same functionality can be achieved using:

	color="blue"
	[[ "$color" == "blue" ]] && echo "🟦" \|\| echo "🟩"
	# Output: 🟦
