pipInstall with pip install ansible==2.5.6
This module will search a file for a line, and ensure that it is present or absent.
This is primarily useful when you want to change a single line in a file only.
# Before 2.3, option 'dest', 'destfile' or 'name' was used instead of 'path'
- name: insert path without converting \r\n
win_lineinfile:
path: c:\file.txt
line: c:\return\new
- win_lineinfile:
path: C:\temp\example.conf
regexp: '^name='
line: 'name=JohnDoe'
- win_lineinfile:
path: C:\temp\example.conf
regexp: '^name='
state: absent
- win_lineinfile:
path: C:\temp\example.conf
regexp: '^127\.0\.0\.1'
line: '127.0.0.1 localhost'
- win_lineinfile:
path: C:\temp\httpd.conf
regexp: '^Listen '
insertafter: '^#Listen '
line: Listen 8080
- win_lineinfile:
path: C:\temp\services
regexp: '^# port for http'
insertbefore: '^www.*80/tcp'
line: '# port for http by default'
# Create file if it doesn't exist with a specific encoding
- win_lineinfile:
path: C:\temp\utf16.txt
create: yes
encoding: utf-16
line: This is a utf-16 encoded file
# Add a line to a file and ensure the resulting file uses unix line separators
- win_lineinfile:
path: C:\temp\testfile.txt
line: Line added to file
newline: unix
# Update a line using backrefs
- win_lineinfile:
path: C:\temp\example.conf
backrefs: yes
regexp: '(^name=)'
line: '$1JohnDoe'
line:
description:
- Required for C(state=present). The line to insert/replace into the file. If C(backrefs)
is set, may contain backreferences that will get expanded with the C(regexp) capture
groups if the regexp matches.
- Be aware that the line is processed first on the controller and thus is dependent
on yaml quoting rules. Any double quoted line will have control characters, such
as '\r\n', expanded. To print such characters literally, use single or no quotes.
required: false
path:
aliases:
- dest
- destfile
- name
description:
- The path of the file to modify.
- Note that the Windows path delimiter C(\) must be escaped as C(\\) when the line
is double quoted.
- Before 2.3 this option was only usable as I(dest), I(destfile) and I(name).
required: true
state:
choices:
- present
- absent
default: present
description:
- Whether the line should be there or not.
required: false
backup:
choices:
- 'yes'
- 'no'
default: '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
create:
choices:
- 'yes'
- 'no'
default: 'no'
description:
- Used with C(state=present). If specified, the file will be created if it does not
already exist. By default it will fail if the file is missing.
required: false
regexp:
description:
- 'The regular expression to look for in every line of the file. For C(state=present),
the pattern to replace if found; only the last line found will be replaced. For
C(state=absent), the pattern of the line to remove. Uses .NET compatible regular
expressions; see U(https://msdn.microsoft.com/en-us/library/hs600312%28v=vs.110%29.aspx).
'
required: false
newline:
choices:
- windows
- unix
default: windows
description:
- 'Specifies the line separator style to use for the modified file. This defaults
to the windows line separator (C(\r\n)). Note that the indicated line separator
will be used for file output regardless of the original line separator that appears
in the input file.
'
required: false
backrefs:
choices:
- 'yes'
- 'no'
default: 'no'
description:
- Used with C(state=present). If set, line can contain backreferences (both positional
and named) that will get populated if the C(regexp) matches. This flag changes the
operation of the module slightly; C(insertbefore) and C(insertafter) will be ignored,
and if the C(regexp) doesn't match anywhere in the file, the file will be left unchanged.
- If the C(regexp) does match, the last matching line will be replaced by the expanded
line parameter.
required: false
encoding:
default: auto
description:
- Specifies the encoding of the source text file to operate on (and thus what the
output encoding will be). The default of C(auto) will cause the module to auto-detect
the encoding of the source file and ensure that the modified file is written with
the same encoding.
- 'An explicit encoding can be passed as a string that is a valid value to pass to
the .NET framework System.Text.Encoding.GetEncoding() method - see U(https://msdn.microsoft.com/en-us/library/system.text.encoding%28v=vs.110%29.aspx).
'
- This is mostly useful with C(create=yes) if you want to create a new file with a
specific encoding. If C(create=yes) is specified without a specific encoding, the
default encoding (UTF-8, no BOM) will be used.
required: false
validate:
default: None
description:
- Validation to run before copying into place. Use %s in the command to indicate the
current file to validate.
- The command is passed securely so shell features like expansion and pipes won't
work.
required: false
insertafter:
choices:
- EOF
- '*regex*'
default: EOF
description:
- Used with C(state=present). If specified, the line will be inserted after the last
match of specified regular expression. A special value is available; C(EOF) for
inserting the line at the end of the file.
- If specified regular expression has no matches, EOF will be used instead. May not
be used with C(backrefs).
required: false
insertbefore:
choices:
- BOF
- '*regex*'
description:
- Used with C(state=present). If specified, the line will be inserted before the last
match of specified regular expression. A value is available; C(BOF) for inserting
the line at the beginning of the file.
- If specified regular expression has no matches, the line will be inserted at the
end of the file. May not be used with C(backrefs).
required: false
