Improved agent CLI

[cborla]

Description

The Wazuh agent CLI needs enhancements to improve the registration process and provide clearer help documentation. Additionally, options should be displayed only for the relevant operating system.

Requirements

Update agent registration command

Currently, the agent registration command is:

.\wazuh-agent.exe --register-agent --user wazuh --password wazuh --url https://192.168.100.121:55000 --verification-mode none

The new command should looks like:

.\wazuh-agent.exe --enroll-agent --user wazuh --password wazuh --enroll-url https://192.168.100.121:55000 --connect-url https://192.168.100.121:27000 --verification-mode none

• --enroll-url → MANDATORY
• --connect-url → OPTIONAL

If --connect-url is provided, the wazuh-agent.yml file should be updated with the specified URL, for example:

server_url: https://192.168.100.121:27000

Improve --help output

Currently, the help command output for registration is:

.\wazuh-agent.exe --register-agent --help
--url, --user and --password args are mandatory

Expected behavior:

• Display all available options for --register-agent with descriptions.
• Ensure clarity on mandatory and optional parameters.

Filter OS-specific options

Currently, some CLI options not applicable to the running OS are displayed. For example, on Windows, these options should only be shown when applicable:

--install-service       Use this option to install Wazuh as a Windows service
--remove-service        Use this option to remove Wazuh Windows service
--run-service           Use this option to run Wazuh as a Windows service

Expected behavior:

• Only show OS-relevant options when using --help.

Definition of Done

• The new --enroll-agent command is implemented.
• The --help output is updated with full descriptions.
• OS-specific options are correctly filtered.
• Tests validate all changes.
• Documentation is updated accordingly.

Update

Started to look into the issue. I'm redesigning main.cpp and process_options files to enable conditional compilation according to platforms.
