aws-ec2:tldr:06880

The command "aws ec2 ${subcommand} help" is used to display help information about a specific subcommand in the AWS EC2 command-line interface (CLI).

Here's how the command breaks down:

• "aws" refers to the AWS CLI command.
• "ec2" specifies the EC2 service in AWS.
• "${subcommand}" is a placeholder that should be replaced with an actual subcommand. Subcommands are specific operations or actions you can perform with the EC2 service, such as "describe-instances" or "create-security-group". For example, if you want to get help information about the "describe-instances" subcommand, you would replace "${subcommand}" with "describe-instances".
• "help" is the parameter that tells the CLI to display the help information for the specified subcommand.

By running this command, you will get detailed information on how to use the specified subcommand, including its available options, input parameters, and example command usage. This helps users understand how to properly structure and execute an AWS EC2 CLI command for a specific task.
