This assumes you have already installed the AWS Serverless Application Model (SAM) CLI. If not, check out my article Download and Install the AWS Serverless Application Model (SAM) CLI on Linux.

Let's create a directory.

mkdir /tmp/sam-hello-world

Move into the directory.

cd /tmp/sam-hello-world

Run the sam init command. In the prompt, let's make the following selections.

• Which template source would you like to use = 1 - AWS Quick Start Templates
• Choose an AWS Quick Start application template = 1 - Hello World Example
• Use the most popular runtime and package type? (Python and zip) [y/N] = y
• Would you like to enable X-Ray tracing on the function(s) in your application?  [y/N] = N
• Would you like to enable monitoring using CloudWatch Application Insights? [y/N] = N
• Project name [sam-app]: press enter to use sam-app

There should now be a directory named /tmp/sam-hello-wolrd/sam-app and inside the sam-app directory should be some Python files, YAML files and directories.
