raw 文檔：
> RAW (/usr/lib/python2.7/site-packages/ansible/modules/commands/raw.py)
Executes a low-down and dirty SSH command, not going through the module subsystem. This is useful and should only be done in
two cases. The first case is installing `python-simplejson' on older (Python 2.4 and before) hosts that need it as a dependency
to run modules, since nearly all core modules require it. Another is speaking to any devices such as routers that do not have
any Python installed. In any other case, using the [shell] or [command] module is much more appropriate. Arguments given to
`raw' are run directly through the configured remote shell. Standard output, error output and return code are returned when
available. There is no change handler support for this module. This module does not require python on the remote system, much
like the [script] module. This module is also supported for Windows targets.
* note: This module has a corresponding action plugin.
OPTIONS (= is mandatory):
- executable
change the shell used to execute the command. Should be an absolute path to the executable.
when using privilege escalation (`become'), a default shell will be assigned if one is not provided as privilege escalation
requires a shell.
[Default: (null)]
version_added: 1.0
= free_form
the raw module takes a free form command to run. There is no parameter actually named 'free form'; see the examples!
NOTES:
* If using raw from a playbook, you may need to disable fact gathering using `gather_facts: no' if you're using `raw' to
bootstrap python onto the machine.
* If you want to execute a command securely and predictably, it may be better to use the [command] or [shell] modules
instead.
* the `environment' keyword does not work with raw normally, it requires a shell which means it only works if `executable'
is set or using the module with privilege escalation (`become').
* This module is also supported for Windows targets.

EXAMPLES:
- name: Bootstrap a legacy python 2.4 host
raw: yum -y install python-simplejson
- name: Bootstrap a host without python2 installed
raw: dnf install -y python2 python2-dnf libselinux-python
- name: Run a command that uses non-posix shell-isms (in this example /bin/sh doesn't handle redirection and wildcards together but bash does)
raw: cat < /tmp/*txt
args:
executable: /bin/bash
- name: safely use templated variables. Always use quote filter to avoid injection issues.
