Use :py:func:`~salt.modules.file.replace` instead.
Uncomment specified commented lines in a file
path
The full path to the file to be edited
regex
A regular expression used to find the lines that are to be uncommented.
This regex should not include the comment character. A leading ``^``
character will be stripped for convenience (for easily switching
between comment() and uncomment()).
char: ``#``
The character to remove in order to uncomment a line
backup: ``.bak``
The file will be backed up before edit with this file extension;
**WARNING:** each time ``sed``/``comment``/``uncomment`` is called will
overwrite this backup
CLI Example:
salt '*' file.uncomment /etc/hosts.deny 'ALL: PARANOID'
file.delete_backup
New in version 0.17.0
Delete a previous version of a file that was backed up using Salt's
:ref:`file state backup <file-state-backups>` system.
path
The path on the minion to check for backups
backup_id
The numeric id for the backup you wish to delete, as found using

file.lsattr
New in version 2018.3.0
Changed in version 2018.3.1
If ``lsattr`` is not installed on the system, ``None`` is returned.
Changed in version 2018.3.4
If on ``AIX``, ``None`` is returned even if in filesystem as lsattr on ``AIX``
is not the same thing as the linux version.
Obtain the modifiable attributes of the given file. If path
is to a directory, an empty list is returned.
path

file.replace
New in version 0.17.0
Replace occurrences of a pattern in a file. If ``show_changes`` is
``True``, then a diff of what changed will be returned, otherwise a
``True`` will be returned when changes are made, and ``False`` when
no changes are made.
This is a pure Python implementation that wraps Python's :py:func:`~re.sub`.
path
Filesystem path to the file to be edited. If a symlink is specified, it
will be resolved to its target.
pattern
A regular expression, to be matched using Python's
:py:func:`~re.search`.
repl
The replacement text
count: 0
Maximum number of pattern occurrences to be replaced. If count is a
positive integer ``n``, only ``n`` occurrences will be replaced,
otherwise all occurrences will be replaced.
flags (list or int)
A list of flags defined in the ``re`` module documentation from the
Python standard library. Each list item should be a string that will
correlate to the human-friendly flag name. E.g., ``['IGNORECASE',
'MULTILINE']``. Optionally, ``flags`` may be an int, with a value
corresponding to the XOR (``|``) of all the desired flags. Defaults to
8 (which supports 'MULTILINE').
bufsize (int or str)
How much of the file to buffer into memory at once. The
default value ``1`` processes one line at a time. The special value
``file`` may be specified which will read the entire file into memory
before processing.
append_if_not_found: False
New in version 2014.7.0
If set to ``True``, and pattern is not found, then the content will be
appended to the file.
prepend_if_not_found: False
New in version 2014.7.0
If set to ``True`` and pattern is not found, then the content will be
prepended to the file.
not_found_content
New in version 2014.7.0
Content to use for append/prepend if not found. If None (default), uses
``repl``. Useful when ``repl`` uses references to group in pattern.
backup: .bak
The file extension to use for a backup of the file before editing. Set
to ``False`` to skip making a backup.
dry_run: False
If set to ``True``, no changes will be made to the file, the function
will just return the changes that would have been made (or a
``True``/``False`` value if ``show_changes`` is set to ``False``).
search_only: False
If set to true, this no changes will be performed on the file, and this
function will simply return ``True`` if the pattern was matched, and
``False`` if not.
show_changes: True
If ``True``, return a diff of changes made. Otherwise, return ``True``
if changes were made, and ``False`` if not.
Note:
Using this option will store two copies of the file in memory (the
original version and the edited version) in order to generate the
diff. This may not normally be a concern, but could impact
performance if used with large files.
ignore_if_missing: False
New in version 2015.8.0
If set to ``True``, this function will simply return ``False``
if the file doesn't exist. Otherwise, an error will be thrown.
preserve_inode: True
New in version 2015.8.0
Preserve the inode of the file, so that any hard links continue to
share the inode with the original filename. This works by *copying* the
file, reading from the copy, and writing to the file at the original
inode. If ``False``, the file will be *moved* rather than copied, and a
new file will be written to a new inode, but using the original
filename. Hard links will then share an inode with the backup, instead
(if using ``backup`` to create a backup copy).
backslash_literal: False
New in version 2016.11.7
Interpret backslashes as literal backslashes for the repl and not
escape characters. This will help when using append/prepend so that
the backslashes are not interpreted for the repl on the second run of
the state.
If an equal sign (``=``) appears in an argument to a Salt command it is
interpreted as a keyword argument in the format ``key=val``. That
processing can be bypassed in order to pass an equal sign through to the
remote shell command by manually specifying the kwarg:
salt '*' file.replace /path/to/file pattern='=' repl=':'
salt '*' file.replace /path/to/file pattern="bind-address\s*=" repl='bind-address:'
CLI Examples:
salt '*' file.replace /etc/httpd/httpd.conf pattern='LogLevel warn' repl='LogLevel info'
salt '*' file.replace /some/file pattern='before' repl='after' flags='[MULTILINE, IGNORECASE]'
file.manage_file
Checks the destination against what was retrieved with get_managed and
makes the appropriate modifications (if necessary).
name
location to place the file
sfn
location of cached file on the minion
This is the path to the file stored on the minion. This file is placed
on the minion using cp.cache_file. If the hash sum of that file
matches the source_sum, we do not transfer the file to the minion
again.
This file is then grabbed and if it has template set, it renders the
file to be placed into the correct place on the system using
salt.files.utils.copyfile()
ret
The initial state return data structure. Pass in ``None`` to use the
default structure.
source
file reference on the master
source_sum

skip_verify: False
If ``True``, hash verification of remote file sources (``http://``,
``https://``, ``ftp://``) will be skipped, and the ``source_hash``
argument will be ignored.
New in version 2016.3.0
keep_mode: False
If ``True``, and the ``source`` is a file from the Salt fileserver (or
a local file on the minion), the mode of the destination file will be
set to the mode of the source file.
Note: keep_mode does not work with salt-ssh.
As a consequence of how the files are transferred to the minion, and
the inability to connect back to the master with salt-ssh, salt is
unable to stat the file as it exists on the fileserver and thus
cannot mirror the mode on the salt-ssh minion
encoding
If specified, then the specified encoding will be used. Otherwise, the
file will be encoded using the system locale (usually UTF-8). See
https://docs.python.org/3/library/codecs.html#standard-encodings for
the list of available encodings.
New in version 2017.7.0
encoding_errors: 'strict'

path
path to file
length
offset into file to truncate
CLI Example:
salt '*' file.truncate /path/to/file 512
file.extract_hash
Changed in version 2016.3.5
Prior to this version, only the ``file_name`` argument was considered
for filename matches in the hash file. This would be problematic for
cases in which the user was relying on a remote checksum file that they
do not control, and they wished to use a different name for that file
on the minion from the filename on the remote server (and in the
checksum file). For example, managing ``/tmp/myfile.tar.gz`` when the
remote file was at ``https://mydomain.tld/different_name.tar.gz``. The
:py:func:`file.managed <salt.states.file.managed>` state now also
passes this function the source URI as well as the ``source_hash_name``
(if specified). In cases where ``source_hash_name`` is specified, it
takes precedence over both the ``file_name`` and ``source``. When it is
not specified, ``file_name`` takes precedence over ``source``. This
allows for better capability for matching hashes.
Changed in version 2016.11.0
File name and source URI matches are no longer disregarded when
``source_hash_name`` is specified. They will be used as fallback
matches if there is no match to the ``source_hash_name`` value.
This routine is called from the :mod:`file.managed
<salt.states.file.managed>` state to pull a hash from a remote file.
Regular expressions are used line by line on the ``source_hash`` file, to
find a potential candidate of the indicated hash type. This avoids many
problems of arbitrary file layout rules. It specifically permits pulling
hash codes from debian ``*.dsc`` files.
If no exact match of a hash and filename are found, then the first hash
found (if any) will be returned. If no hashes at all are found, then
``None`` will be returned.
For example:
openerp_7.0-latest-1.tar.gz:
file.managed:
- name: /tmp/openerp_7.0-20121227-075624-1_all.deb
- source: http://nightly.openerp.com/7.0/nightly/deb/openerp_7.0-20121227-075624-1.tar.gz
- source_hash: http://nightly.openerp.com/7.0/nightly/deb/openerp_7.0-20121227-075624-1.dsc

If you need to pass a string to append and that string contains
an equal sign, you **must** include the argument name, args.
For example:
salt '*' file.write /etc/motd args='cheese=spam'
salt '*' file.write /etc/motd args="['cheese=spam','spam=cheese']"
file.sed_contains
.. deprecated:: 0.17.0

For this and newer versions the hash can be specified without an
accompanying hash type (e.g. ``e138491e9d5b97023cea823fe17bac22``),
but for earlier releases it is necessary to also specify the hash type
in the format ``<hash_type>=<hash_value>`` (e.g.
``md5=e138491e9d5b97023cea823fe17bac22``).
CLI Example:
salt '*' file.check_hash /etc/fstab e138491e9d5b97023cea823fe17bac22

CLI Example:
The following example will comment out the ``pcspkr`` line in the
``/etc/modules`` file using the default ``#`` character and create a backup
file named ``modules.bak``
salt '*' file.comment_line '/etc/modules' '^pcspkr'
CLI Example:
The following example will uncomment the ``log_level`` setting in ``minion``
config file if it is set to either ``warning``, ``info``, or ``debug`` using

Get the hash sum of a file
This is better than ``get_sum`` for the following reasons:
- It does not read the entire file into memory.
- It does not return a string on error. The returned value of
``get_sum`` cannot really be trusted since it is vulnerable to
collisions: ``get_sum(..., 'xyz') == 'Hash xyz not supported'``

remove_existing will remove all files in the target directory,
and then copy files from the source.
Note:
The copy function accepts paths that are local to the Salt minion.
This function does not support salt://, http://, or the other
additional file paths that are supported by :mod:`states.file.managed
<salt.states.file.managed>` and :mod:`states.file.recurse
<salt.states.file.recurse>`.
CLI Example:
salt '*' file.copy /path/to/src /path/to/dst
salt '*' file.copy /path/to/src_dir /path/to/dst_dir recurse=True
salt '*' file.copy /path/to/src_dir /path/to/dst_dir recurse=True remove_existing=True

``source_hash`` is a hash expression, then this argument will be
ignored.
source_hash
Hash file/expression, as used in :py:mod:`file <salt.states.file>` and
other states. If this value refers to a remote URL or absolute path to
a local file, it will be cached and :py:func:`file.extract_hash
<salt.modules.file.extract_hash>` will be used to obtain a hash from
it.
source_hash_name
Specific file name to look for when ``source_hash`` refers to a remote
file, used to disambiguate ambiguous matches.
saltenv: base

file.get_diff
Return unified diff of two files
file1
The first file to feed into the diff utility
Changed in version 2018.3.0

arguments are required, as well as passing in one of the ``mode``
options.
path
Filesystem path to the file to be edited.
content
Content of the line. Allowed to be empty if mode=delete.
match
Match the target line for an action by
a fragment of a string or regular expression.
If neither ``before`` nor ``after`` are provided, and ``match``
is also ``None``, match becomes the ``content`` value.
mode
Defines how to edit a line. One of the following options is
required:
- ensure
If line does not exist, it will be added. This is based on the
``content`` argument.
- replace
If line already exists, it will be replaced.
- delete
Delete the line, once found.
- insert
Insert a line.
Note:
If ``mode=insert`` is used, at least one of the following
options must also be defined: ``location``, ``before``, or
``after``. If ``location`` is used, it takes precedence
over the other two options.
location
Defines where to place content in the line. Note this option is only
used when ``mode=insert`` is specified. If a location is passed in, it
takes precedence over both the ``before`` and ``after`` kwargs. Valid
locations are:
- start
Place the content at the beginning of the file.
- end
Place the content at the end of the file.
before
Regular expression or an exact case-sensitive fragment of the string.
This option is only used when either the ``ensure`` or ``insert`` mode
is defined.

This option is only used when either the ``ensure`` or ``insert`` mode
is defined.
show_changes
Output a unified diff of the old file and the new file.

Default is ``True``
Note:
Using this option will store two copies of the file in-memory
(the original version and the edited version) in order to generate the diff.
backup
Create a backup of the original file with the extension:
"Year-Month-Day-Hour-Minutes-Seconds".
quiet
Do not raise any exceptions. E.g. ignore the fact that the file that is
tried to be edited does not exist and nothing really happened.
indent
Keep indentation with the previous line. This option is not considered when
the ``delete`` mode is specified.
CLI Example:
salt '*' file.line /etc/nsswitch.conf "networks: files dns" after="hosts:.*?" mode='ensure'
Note:
If an equal sign (``=``) appears in an argument to a Salt command, it is
interpreted as a keyword argument in the format of ``key=val``. That
processing can be bypassed in order to pass an equal sign through to the
remote shell command by manually specifying the kwarg:
salt '*' file.line /path/to/file content="CREATEMAIL_SPOOL=no" match="CREATE_MAIL_SPOOL=yes" mode="replace"

edit the targeted file if necessary.
path
Filesystem path to the file to be edited
marker_start
The line content identifying a line as the start of the content block.
Note that the whole line containing this marker will be considered, so
whitespace or extra content before or after the marker is included in
final output
marker_end
The line content identifying the end of the content block. As of

return a unified diff of the changes made. If False, then it will
return a boolean (``True`` if any changes were made, otherwise
``False``).
append_newline: False
Controls whether or not a newline is appended to the content block. If
the value of this argument is ``True`` then a newline will be added to
