aws [service] [command] help

aws help displays comprehensive documentation for AWS CLI commands. It shows syntax, parameters, examples, and related commands using a pager interface.
Help is available at every level: general CLI help, service-specific help, and individual command help.

Documentation includes:
- Command syntax and structure
- Parameter descriptions and types
- Usage examples
- Available subcommands
- Output format details
- Related commands

Within help pager:
- Space - Page down
- b - Page up
- / - Search
- q - Quit

Opens in pager by default (use --no-cli-pager to disable). Requires internet connection for complete documentation in some cases. Help text can be very long for complex commands.

The help command has been part of the AWS CLI since its initial release in 2013, providing inline documentation for all services and commands.
