module: replace
|
||||
author: Evan Kaufman
|
||||
short_description: Replace all instances of a particular string in a
|
||||
file using a back-referenced regular expression.
|
||||
description:
|
||||
- This module will replace all instances of a pattern within a file.
|
||||
- It is up to the user to maintain idempotence by ensuring that the
|
||||
same pattern would never match any replacements made.
|
||||
version_added: "1.4"
|
||||
options:
|
||||
dest:
|
||||
required: true
|
||||
aliases: [ name, destfile ]
|
||||
description:
|
||||
- The file to modify.
|
||||
regexp:
|
||||
required: true
|
||||
description:
|
||||
- The regular expression to look for in the contents of the file.
|
||||
Uses Python regular expressions; see
|
||||
U(http://docs.python.org/2/library/re.html).
|
||||
Uses multiline mode, which means C(^) and C($) match the beginning
|
||||
and end respectively of I(each line) of the file.
|
||||
replace:
|
||||
required: false
|
||||
description:
|
||||
- The string to replace regexp matches. May contain backreferences
|
||||
that will get expanded with the regexp capture groups if the regexp
|
||||
matches. If not set, matches are removed entirely.

||||
backup:
|
||||
required: false
|
||||
default: "no"
|
||||
choices: [ "yes", "no" ]
|
||||
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
