Purpose

I use the following playbook in AAP to test my AWS instances to ensure they are using BYOS Linux vs the more expensive PAYG images.

Usage

You will need an inventory source, and playbook.

Create a template from the playbook, and run it. It will error if any instances are not BYOS.

N=$(tput sgr0)
B=$(tput bold)

banner() {
	_width=$(tput cols)
	tput bold
	python3 -c "print('#' * $_width)"
	tput sgr0

#!/bin/sh
# usage: ./getldd mybinary
#   will hard copy all the shared libs to
DEPS=/tmp/deps.txt

getldd() {
        for i in $(ldd $1 | grep / | xargs echo) ; do
                test -r "$i" && realpath "$i" && getldd $i
        done
