What does the Ansible module know?

I used ansible in the company for a while and shared the introduction about the use of the ansible module.

Ansible provides many modules by default. In Linux, we can run the ansible-doc-l command to check which modules are supported by ansible, you can use the ansible-doc-s Module name to view the parameters available for this module.

The following describes several common modules:

File Module
Cron Module
Group Module
User Module
Yum Module
Service Module
Script Module
Ping Module
Command Module
Raw Module
Get_url Module
