Great question! Writing a Python script is totally valid, but there are simpler shell/PowerShell-based approaches that let you reuse your existing AWS CLI commands without full scripting. Here are a couple of straightforward options:

Option 1: Bash/Zsh with AWS CLI (no extra tools needed) #

You can use the AWS CLI's --output text to get a space-separated list of stack names, then loop through each one to fetch its resources:

# Retrieve all relevant nested stack names (space-separated)
STACKS=$(aws cloudformation list-stacks \
  --query 'StackSummaries[?contains(StackName, `MYSTACKNAME`) && (StackStatus==`CREATE_COMPLETE`||StackStatus==`UPDATE_COMPLETE`)].StackName' \
  --output text)

# Loop through each stack and print its resources
for STACK in $STACKS; do
  echo -e "\n=== Resources for Stack: $STACK ==="
  aws cloudformation describe-stack-resources \
    --stack-name "$STACK" \
    --query 'StackResources[*].{Type:ResourceType,LogicalID:LogicalResourceId}' \
    --output table
done

This works without any additional tools since we're using --output text to format the stack names into a loop-friendly list.

Option 2: Bash/Zsh with jq (for cleaner JSON parsing) #

If you have jq installed (a common JSON processing tool), you can parse the stack names more reliably—especially useful if stack names contain spaces:

# Get stack names as a newline-separated list using jq
STACKS=$(aws cloudformation list-stacks \
  --query 'StackSummaries[?contains(StackName, `MYSTACKNAME`) && (StackStatus==`CREATE_COMPLETE`||StackStatus==`UPDATE_COMPLETE`)].StackName' \
  --output json | jq -r '.[]')

# Loop through each stack
while IFS= read -r STACK; do
  echo -e "\n=== Resources for Stack: $STACK ==="
  aws cloudformation describe-stack-resources \
    --stack-name "$STACK" \
    --query 'StackResources[*].{Type:ResourceType,LogicalID:LogicalResourceId}' \
    --output table
done <<< "$STACKS"

Option 3: PowerShell (for Windows users) #

If you prefer PowerShell, the approach is similar—parse the JSON output and loop through each stack:

# Fetch stack names and convert JSON to PowerShell objects
$stacks = aws cloudformation list-stacks `
  --query 'StackSummaries[?contains(StackName, `MYSTACKNAME`) && (StackStatus==`CREATE_COMPLETE`||StackStatus==`UPDATE_COMPLETE`)].StackName' `
  --output json | ConvertFrom-Json

# Iterate over each stack and retrieve resources
foreach ($stack in $stacks) {
  Write-Host "`n=== Resources for Stack: $stack ==="
  aws cloudformation describe-stack-resources `
    --stack-name $stack `
    --query 'StackResources[*].{Type:ResourceType,LogicalID:LogicalResourceId}' `
    --output table
}

Notes for deeper nested stacks #

If your nested stacks have their own nested stacks (multi-level hierarchy), these basic loops won't recurse automatically. For that scenario, a Python script (or a more advanced shell function with recursion) would be better, but for single-level nested stacks, the above methods are quick and easy.
