module: ini_file
short_description: Tweak settings in INI files
description:
- Manage (add, remove, change) individual settings in an INI-style file without having
to manage the file as a whole with, say, M(template) or M(assemble). Adds missing
sections if they don't exist.
version_added: "0.9"
options:
dest:
description:
- Path to the INI-style file; this file is created if required
required: true
default: null
section:
description:
- Section name in INI file. This is added if C(state=present) automatically when
a single value is being set.
required: true
default: null
option:
description:
- if set (required for changing a I(value)), this is the name of the option.
- May be omitted if adding/removing a whole I(section).
required: false
default: null
value:
description:
- the string value to be associated with an I(option). May be omitted when removing an I(option).
required: false
default: null
backup:
description:
- Create a backup file including the timestamp information so you can get
the original file back if you somehow clobbered it incorrectly.
required: false
default: no
choices: [ "yes", "no" ]
others:
description:
- all arguments accepted by the M(file) module also work here
required: false
examples:
- code: "ini_file: dest=/etc/conf section=drinks option=fav value=lemonade mode=0600 backup=yes"
description: Ensure C(fav=lemonade) is in section C([drinks]) in said file
- code: |
ini_file: dest=/etc/anotherconf
section=drinks
option=temperature
value=cold
backup=yes
notes:
- While it is possible to add an I(option) without specifying a I(value), this makes
no sense.
