---
module: raw
short_description: Executes a low-down and dirty SSH command
version_added: historical
options:
free_form:
description:
- the raw module takes a free form command to run. There is no parameter actually named 'free form'; see the examples!
required: true
executable:
description:
- change the shell used to execute the command. Should be an absolute path to the executable.
- when using privilege escalation (C(become)), a default shell will be assigned if one is not provided
as privilege escalation requires a shell.
required: false
version_added: "1.0"
description:
- 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 C(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 M(shell) or M(command) module is much more appropriate. Arguments
given to C(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 M(script) module.
- This module is also supported for Windows targets.
notes:
- "If using raw from a playbook, you may need to disable fact gathering
using C(gather_facts: no) if you're using C(raw) to bootstrap python
onto the machine."
- If you want to execute a command securely and predictably, it may be
better to use the M(command) or M(shell) modules instead.
- the C(environment) keyword does not work with raw normally, it requires a shell
which means it only works if C(executable) is set or using the module
with privilege escalation (C(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.
