versions.sh queries the version of every shell runtime and AWS CLI tool present in the CloudShell environment and prints the results to stdout. No write operations are performed — it is purely read-only.

​
Run the command

curl -LfsS https://link.rwick.it/aws-cloudshell-versions | bash

​
What the script checks

scripts/versions.sh
#!/bin/bash

echo ""
echo "Getting Shell Versions..."
echo ""

bash --version
echo ""

zsh --version
echo ""

pwsh --version
echo ""

echo "Getting AWS CLI Versions..."
echo ""

aws --version
echo ""

eb --version
echo ""

ecs-cli --version
echo ""

sam --version
echo ""

​
Expected output

The script produces two groups of output:
  • “Getting Shell Versions…” — displays the output of bash --version, zsh --version, and pwsh --version in sequence, each separated by a blank line.
  • “Getting AWS CLI Versions…” — displays the output of aws --version, eb --version, ecs-cli --version, and sam --version in sequence, each separated by a blank line.
Output format varies per tool. Some tools print a single version string; others (like aws --version) include platform and Python version info.

​
When to use this

  • Before running deployments to confirm tool versions
  • After a CloudShell session restart to verify the environment state
  • When troubleshooting compatibility issues with AWS services
  • To document the exact tool versions used in a deployment
AWS CloudShell environments are periodically updated by AWS. Run this script at the start of a session to confirm the current state of your environment.
