4.) To list about any particular module.
[root@ansimaster ~]# ansible-doc ping
> PING (/usr/lib/python2.7/site-packages/ansible/modules/system/ping.py)
A trivial test module, this module always returns `pong' on successful contact. It does not make
sense in playbooks, but it is useful from `/usr/bin/ansible' to verify the ability to login and that
a usable Python is configured. This is NOT ICMP ping, this is just a trivial test module that
requires Python on the remote-node. For Windows targets, use the [win_ping] module instead. For
Network targets, use the [net_ping] module instead.
OPTIONS (= is mandatory):
- data
Data to return for the `ping' return value.
If this parameter is set to `crash', the module will cause an exception.
[Default: pong]
NOTES:
* For Windows targets, use the [win_ping] module instead.
* For Network targets, use the [net_ping] module instead.
