You are viewing docs from the master branch, some of these features are not yet released.

salt.modules.file¶

Manage information about regular files, directories, and special files on the minion, set/read user, group, mode, and data

class salt.modules.file.AttrChanges(added, removed)¶

added¶: Alias for field number 0

removed¶: Alias for field number 1

salt.modules.file.access(path, mode)¶

New in version 2014.1.0.

Test whether the Salt process has the specified access to the file. One of the following modes must be specified:

f: Test the existence of the path
r: Test the readability of the path
w: Test the writability of the path
x: Test whether the path can be executed

CLI Example:

salt '*' file.access /path/to/file f
salt '*' file.access /path/to/file x

salt.modules.file.append(path, *args, **kwargs)¶

New in version 0.9.5.

Append text to the end of a file

path: path to file
*args: strings to append to file

CLI Example:

salt '*' file.append /etc/motd \
        "With all thine offerings thou shalt offer salt." \
        "Salt is what makes things taste bad when it isn't in them."

Attention

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.append /etc/motd args='cheese=spam'

salt '*' file.append /etc/motd args="['cheese=spam','spam=cheese']"

salt.modules.file.apply_template_on_contents(contents, template, context, defaults, saltenv)¶

Return the contents after applying the templating engine

contents: template string
template: template format
context: Overrides default context variables passed to the template.
defaults: Default context passed to the template.

CLI Example:

salt '*' file.apply_template_on_contents \
    contents='This is a {{ template }} string.' \
    template=jinja \
    "context={}" "defaults={'template': 'cool'}" \
    saltenv=base

salt.modules.file.basename(path)¶

Returns the final component of a pathname

New in version 2015.5.0.

This can be useful at the CLI but is frequently useful when scripting.

{%- set filename = salt['file.basename'](source_file) %}

CLI Example:

salt '*' file.basename 'test/test.config'

salt.modules.file.blockreplace(path, marker_start='#-- start managed zone --', marker_end='#-- end managed zone --', content='', append_if_not_found=False, prepend_if_not_found=False, backup='.bak', dry_run=False, show_changes=True, append_newline=False, insert_before_match=None, insert_after_match=None)¶

New in version 2014.1.0.

Replace content of a text block in a file, delimited by line markers

A block of content delimited by comments can help you manage several lines entries without worrying about old entries removal.

Note

This function will store two copies of the file in-memory (the original version and the edited version) in order to detect changes and only 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 versions 2017.7.5 and 2018.3.1, everything up to the text matching the marker will be replaced, so it's important to ensure that your marker includes the beginning of the text you wish to replace.
content: The content to be used between the two lines identified by marker_start and marker_stop.
append_if_not_found: False: If markers are not found and set to True then, the markers and content will be appended to the file.
prepend_if_not_found: False: If markers are not found and set to True then, the markers and content will be prepended to the file.
insert_before_match: If markers are not found, this parameter can be set to a regex which will insert the block before the first found occurrence in the file.

New in version 3001.
insert_after_match: If markers are not found, this parameter can be set to a regex which will insert the block after the first found occurrence in the file.

New in version 3001.
backup: The file extension to use for a backup of the file if any edit is made. Set to False to skip making a backup.
dry_run: False: If True, do not make any edits to the file and simply return the changes that would be made.
show_changes: True: Controls how changes are presented. If True, this function will 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 the content block. If it is False, then a newline will not be added to the content block. If it is None then a newline will only be added to the content block if it does not already end in a newline.

New in version 2016.3.4.

Changed in version 2017.7.5,2018.3.1: New behavior added when value is None.

Changed in version 2019.2.0: The default value of this argument will change to None to match the behavior of the file.blockreplace state

CLI Example:

salt '*' file.blockreplace /etc/hosts '#-- start managed zone foobar : DO NOT EDIT --' \
'#-- end managed zone foobar --' $'10.0.1.1 foo.foobar\n10.0.1.2 bar.foobar' True

salt.modules.file.chattr(*files, **kwargs)¶

New in version 2018.3.0.

Change the attributes of files. This function accepts one or more files and the following options:

operator: Can be wither add or remove. Determines whether attributes should be added or removed from files
attributes: One or more of the following characters: aAcCdDeijPsStTu, representing attributes to add to/remove from files
version: a version number to assign to the file(s)
flags: One or more of the following characters: RVf, representing flags to assign to chattr (recurse, verbose, suppress most errors)

CLI Example:

salt '*' file.chattr foo1.txt foo2.txt operator=add attributes=ai
salt '*' file.chattr foo3.txt operator=remove attributes=i version=2

salt.modules.file.check_file_meta(name, sfn, source, source_sum, user, group, mode, attrs, saltenv, contents=None, seuser=None, serole=None, setype=None, serange=None, verify_ssl=True, follow_symlinks=False, ignore_ordering=False, ignore_whitespace=False, ignore_comment_characters=None, new_file_diff=False)¶

Check for the changes in the file metadata.

This behavior is useful for bringing existing application deployments under Salt configuration management without disrupting production applications with a service restart.

New in version 3007.0.

ignore_whitespace

If True, changes in whitespace will be ignored ONLY for the purposes of triggering watch/onchanges requisites. Changes will still be made to the file to bring it into alignment with requested state, and also reported during the state run.

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

salt.modules.file.comment(path, regex, char='#', backup='.bak')¶

Deprecated since version 0.17.0: Use replace() instead.

Comment out specified 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 commented; this pattern will be wrapped in parenthesis and will move any preceding/trailing ^ or $ characters outside the parenthesis (e.g., the pattern ^foo$ will be rewritten as ^(foo)$)
char: #: The character to be inserted at the beginning of a line in order to comment it out
backup: .bak: The file will be backed up before edit with this file extension

Warning

This backup will be overwritten each time sed / comment / uncomment is called. Meaning the backup will only be useful after the first invocation.

CLI Example:

salt '*' file.comment /etc/modules pcspkr

salt.modules.file.comment_line(path, regex, char='#', cmnt=True, backup='.bak')¶

Comment or Uncomment a line in a text file.

Parameters:

path -- string The full path to the text file.
regex -- string A regex expression that begins with ^ that will find the line you wish to comment. Can be as simple as ^color =
char -- string The character used to comment a line in the type of file you're referencing. Default is #
cmnt -- boolean True to comment the line. False to uncomment the line. Default is True.
backup -- string The file extension to give the backup file. Default is .bak Set to False/None to not keep a backup.

Returns:

boolean Returns True if successful, False if not

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 the # character and create a backup file named minion.bk

salt '*' file.comment_line 'C:\salt\conf\minion' '^log_level: (warning|info|debug)' '#' False '.bk'

salt.modules.file.contains(path, text)¶

Deprecated since version 0.17.0: Use search() instead.

Return True if the file at path contains text

CLI Example:

salt '*' file.contains /etc/crontab 'mymaintenance.sh'

salt.modules.file.contains_glob(path, glob_expr)¶

Deprecated since version 0.17.0: Use search() instead.

Return True if the given glob matches a string in the named file

CLI Example:

salt '*' file.contains_glob /etc/foobar '*cheese*'

salt.modules.file.contains_regex(path, regex, lchar='')¶

Deprecated since version 0.17.0: Use search() instead.

Return True if the given regular expression matches on any line in the text of a given file.

If the lchar argument (leading char) is specified, it will strip lchar from the left side of each line before trying to match

CLI Example:

salt '*' file.contains_regex /etc/crontab

salt.modules.file.copy(src, dst, recurse=False, remove_existing=False)¶

Copy a file or directory from source to dst

In order to copy a directory, the recurse flag is required, and will by default overwrite files in the destination with the same path, and retain all other existing files. (similar to cp -r on unix)

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 states.file.managed and 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

salt.modules.file.delete_backup(path, backup_id)¶

New in version 0.17.0.

Delete a previous version of a file that was backed up using Salt's file state backup 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.list_backups

CLI Example:

salt '*' file.delete_backup /var/cache/salt/minion/file_backup/home/foo/bar/baz.txt 0

salt.modules.file.directory_exists(path)¶

Tests to see if path is a valid directory. Returns True/False.

CLI Example:

salt '*' file.directory_exists /etc

salt.modules.file.dirname(path)¶

Returns the directory component of a pathname

New in version 2015.5.0.

This can be useful at the CLI but is frequently useful when scripting.

{%- from salt['file.dirname'](tpldir) + '/vars.jinja' import parent_vars %}

CLI Example:

salt '*' file.dirname 'test/path/filename.config'

salt.modules.file.diskusage(path)¶

Recursively calculate disk usage of path and return it in bytes

CLI Example:

salt '*' file.diskusage /path/to/check

salt.modules.file.extract_hash(hash_fn, hash_type='sha256', file_name='', source='', source_hash_name=None)¶

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 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 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

CLI Example:

salt '*' file.extract_hash /path/to/hash/file sha512 /etc/foo

salt.modules.file.file_exists(path)¶

Tests to see if path is a valid file. Returns True/False.

CLI Example:

salt '*' file.file_exists /etc/passwd

salt.modules.file.find(path, *args, **kwargs)¶

Approximate the Unix find(1) command and return a list of paths that meet the specified criteria.

The options include match criteria:

name    = path-glob                 # case sensitive
iname   = path-glob                 # case insensitive
regex   = path-regex                # case sensitive

grep    = regex                     # search file contents

and/or actions:

delete [= file-types]               # default type = 'f'
exec    = command [arg ...]         # where {} is replaced by pathname
print  [= print-opts]

and/or depth criteria:

maxdepth = maximum depth to transverse in path
mindepth = minimum depth to transverse before checking files or directories

The default action is print=path

?                = match any char
[abc]            = match a, b, or c
[!abc] or [^abc] = match anything except a, b, and c
[x-y]            = match chars x through y
[!x-y] or [^x-y] = match anything except chars x through y

New in version 2018.3.0.
source_hash_file1: If file1 is an http(s)/ftp URL and the file exists in the minion's file cache, this option can be passed to keep the minion from re-downloading the archive if the cached copy matches the specified hash.

New in version 2018.3.0.
source_hash_file2: If file2 is an http(s)/ftp URL and the file exists in the minion's file cache, this option can be passed to keep the minion from re-downloading the archive if the cached copy matches the specified hash.

salt.modules.file.get_hash(path, form='sha256', chunk_size=65536)¶

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'

path

path to the file or directory

form

desired sum format

chunk_size

amount to sum at once

CLI Example:

salt '*' file.get_hash /etc/shadow

New in version 2016.11.0.

Used by file.get_managed to obtain the hash and hash type from the parameters specified below.

file_name: Optional file name being managed, for matching with file.extract_hash.
source: Source file, as used in file and other states. If source_hash refers to a file containing hashes, then this filename will be used to match a filename in that file. If the source_hash is a hash expression, then this argument will be ignored.
source_hash: Hash file/expression, as used in file and other states. If this value refers to a remote URL or absolute path to a local file, it will be cached and file.extract_hash will be used to obtain a hash from it.

salt.modules.file.gid_to_group(gid)¶

Convert the group id to the group name on this system

gid: gid to convert to a group name

CLI Example:

salt '*' file.gid_to_group 0

salt.modules.file.grep(path, pattern, *opts)¶

Grep for a string in the specified file

Note

This function's return value is slated for refinement in future versions of Salt

Windows does not support the grep functionality.

path: Path to the file to be searched

Note

Globbing is supported (i.e. /var/log/foo/*.log, but if globbing is being used then the path should be quoted to keep the shell from attempting to expand the glob expression.
pattern: Pattern to match. For example: test, or a[0-5]
opts: Additional command-line flags to pass to the grep command. For example: -v, or -i -B2

Note

The options should come after a double-dash (as shown in the examples below) to keep Salt's own argument parser from interpreting them.

CLI Example:

salt '*' file.grep /etc/passwd nobody
salt '*' file.grep /etc/sysconfig/network-scripts/ifcfg-eth0 ipaddr -- -i
salt '*' file.grep /etc/sysconfig/network-scripts/ifcfg-eth0 ipaddr -- -i -B2

{% set www_root = '/var' %}
{% set app_dir = 'myapp' %}

myapp_config:
  file:
    - managed
    - name: {{ salt['file.join'](www_root, app_dir, 'config.yaml') }}

CLI Example:

salt '*' file.join '/' 'usr' 'local' 'bin'

Chown a file, pass the file the desired user and group without following symlinks.

path: path to the file or directory
user: user owner
group: group owner

CLI Example:

salt.modules.file.line(path, content=None, match=None, mode=None, location=None, before=None, after=None, show_changes=True, backup=False, quiet=False, indent=True)¶

New in version 2015.8.0.

Line-focused editing of a file.

Note

file.line exists for historic reasons, and is not generally recommended. It has a lot of quirks. You may find file.replace to be more suitable.

file.line is most useful if you have single lines in a file (potentially a config file) that you would like to manage. It can remove, add, and replace a single line at a time.

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 falls back to 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. If before and after are specified either zero lines, or lines that contain the content line are allowed to be in between before and after. If there are lines, and none of them match then it will produce an error.
replace
If line already exists, the entire line will be replaced.
delete
Delete the line, if found.
insert
Nearly identical to ensure. If a line does not exist, it will be added.

The differences are that multiple (and non-matching) lines are alloweed between before and after, if they are specified. The line will always be inserted right before before. insert also allows the use of location to specify that the line should be added at the beginning or end of the file.

Note

If mode='insert' is used, at least one of location, before, or after is required. If location is used, before and after are ignored.

location

In mode='insert' only, whether to place the content at the beginning or end of a the file. If location is provided, before and after are ignored. Valid locations:

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. Will be tried as both a regex and a part of the line. Must match exactly one line in the file. This value is only used in ensure and insert modes. The content will be inserted just before this line, with matching indentation unless indent=False.

after

Regular expression or an exact case-sensitive fragment of the string. Will be tried as both a regex and a part of the line. Must match exactly one line in the file. This value is only used in ensure and insert modes. The content will be inserted directly after this line, unless before is also provided. If before is not provided, indentation will match this line, unless indent=False.

show_changes

Output a unified diff of the old file and the new file. If False return a boolean if any changes were made. 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. Default is True

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"

Examples:

Here's a simple config file.

[some_config]
# Some config file
# this line will go away

here=False
away=True
goodybe=away

salt \* file.line /some/file.conf mode=delete match=away

This will produce:

[some_config]
# Some config file

here=False
away=True
goodbye=away

If that command is executed 2 more times, this will be the result:

[some_config]
# Some config file

here=False

If we reset the file to its original state and run

salt \* file.line /some/file.conf mode=replace match=away content=here

Three passes will this state will result in this file:

[some_config]
# Some config file
here

here=False
here
here

Each pass replacing the first line found.

Given this file:

insert after me
something
insert before me

The following command

salt \* file.line /some/file.txt mode=insert after="insert after me" before="insert before me" content=thrice

If that command is executed 3 times, the result will be:

insert after me
something
thrice
thrice
thrice
insert before me

If the mode is ensure instead, it will fail each time. To succeed, we need to remove the incorrect line between before and after:

insert after me
insert before me

With an ensure mode, this will insert thrice the first time and make no changes for subsequent calls. For something simple this is fine, but if you have instead blocks like this:

Begin SomeBlock
    foo = bar
End

Begin AnotherBlock
    another = value
End

And you try to use ensure this way:

salt \* file.line  /tmp/fun.txt mode="ensure" content="this = should be my content" after="Begin SomeBlock" before="End"

This will fail because there are multiple End lines. Without that problem, it still would fail because there is a non-matching line, foo = bar. Ensure only allows either zero, or the matching line present to be present in between before and after.

salt.modules.file.link(src, path)¶

New in version 2014.1.0.

Create a hard link to a file

salt.modules.file.lsattr(path)¶

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: path to file to obtain attributes of. File/directory must exist.

CLI Example:

salt '*' file.lsattr foo1.txt

salt.modules.file.lstat(path)¶

New in version 2014.1.0.

Returns the lstat attributes for the given file or dir. Does not support symbolic links.

CLI Example:

salt '*' file.lstat /path/to/file

salt.modules.file.makedirs_(path, user=None, group=None, mode=None)¶

Ensure that the directory containing this path is available.

Note

The path must end with a trailing slash otherwise the directory/directories will be created up to the parent directory. For example if path is /opt/code, then it would be treated as /opt/ but if the path ends with a trailing slash like /opt/code/, then it would be treated as /opt/code/.

CLI Example:

salt '*' file.makedirs /opt/code/

salt.modules.file.makedirs_perms(name, user=None, group=None, mode='0755')¶

Taken and modified from os.makedirs to set user, group and mode for each directory created.

salt.modules.file.manage_file(name, sfn, ret, source, source_sum, user, group, mode, attrs, saltenv, backup, makedirs=False, template=None, show_changes=True, contents=None, dir_mode=None, follow_symlinks=True, skip_verify=False, keep_mode=False, encoding=None, encoding_errors='strict', seuser=None, serole=None, setype=None, serange=None, verify_ssl=True, use_etag=False, signature=None, source_hash_sig=None, signed_by_any=None, signed_by_all=None, keyring=None, gnupghome=None, ignore_ordering=False, ignore_whitespace=False, ignore_comment_characters=None, new_file_diff=False, sig_backend='gpg', **kwargs)¶

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

sum hash for source

user

user owner

group

group owner

backup

backup_mode

attrs

attributes to be set on file: '' means remove all of them

New in version 2018.3.0.

makedirs

make directories if they do not exist

template

format of templating

show_changes

Include diff in state return

contents:

contents to be placed in the file

dir_mode

mode for directories created with makedirs

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'

Default is `'strict'`. See https://docs.python.org/2/library/codecs.html#codec-base-classes for the error handling schemes.

New in version 2017.7.0.

seuser

selinux user attribute

New in version 3001.

serange

selinux range attribute

New in version 3001.

setype

selinux type attribute

New in version 3001.

serange

selinux range attribute

New in version 3001.

verify_ssl

If False, remote https file sources (https://) will not attempt to validate the servers certificate. Default is True.

New in version 3002.

use_etag

If True, remote http/https file sources will attempt to use the ETag header to determine if the remote file needs to be downloaded. This provides a lightweight mechanism for promptly refreshing files changed on a web server without requiring a full hash comparison via the source_hash parameter.

New in version 3005.

signature

Ensure a valid signature exists on the selected source file. Set this to true for inline signatures, or to a file URI retrievable by :py:func:`cp.cache_file <salt.modules.cp.cache_file> for a detached one.

Note

A signature is only enforced directly after caching the file, before it is moved to its final destination. Existing target files (with the correct checksum) will neither be checked nor deleted.

It will be enforced regardless of source type and will be required on the final output, therefore this does not lend itself well when templates are rendered. The file will not be modified, meaning inline signatures are not removed.

New in version 3007.0.

source_hash_sig

When source is a remote file source, source_hash is a file, skip_verify is not true and use_etag is not true, ensure a valid signature exists on the source hash file. Set this to true for an inline (clearsigned) signature, or to a file URI retrievable by :py:func:`cp.cache_file <salt.modules.cp.cache_file> for a detached one.

Note

A signature on the source_hash file is enforced regardless of changes since its contents are used to check if an existing file is in the correct state - but only for remote sources! As for signature, existing target files will not be modified, only the cached source_hash and source_hash_sig files will be removed.

New in version 3007.0.

signed_by_any

When verifying signatures either on the managed file or its source hash file, require at least one valid signature from one of a list of keys. By default, this is passed to gpg.verify, meaning a key is identified by its fingerprint.

New in version 3007.0.

signed_by_all

When verifying signatures either on the managed file or its source hash file, require a valid signature from each of the keys in this list. By default, this is passed to gpg.verify, meaning a key is identified by its fingerprint.

New in version 3007.0.

keyring

When verifying signatures, use this keyring.

New in version 3007.0.

gnupghome

When verifying signatures, use this GnuPG home.

New in version 3007.0.

ignore_ordering

New in version 3007.0.

ignore_whitespace

New in version 3007.0.

ignore_comment_characters

New in version 3007.0.

new_file_diff

If True, creation of new files will still show a diff in the changes return.

New in version 3008.0.

sig_backend

When verifying signatures, use this execution module as a backend. It must be compatible with the gpg.verify API. Defaults to gpg. All signature-related parameters are passed through.

New in version 3008.0.

CLI Example:

salt '*' file.manage_file /etc/httpd/conf.d/httpd.conf '' '{}' salt://http/httpd.conf '{hash_type: 'md5', 'hsum': <md5sum>}' root root '755' '' base ''

Changed in version 2014.7.0: follow_symlinks option added

Create a FIFO pipe.

CLI Example:

salt '*' file.mknod_fifo /dev/fifo

salt.modules.file.move(src, dst, disallow_copy_and_unlink=False)¶

Move a file or directory

disallow_copy_and_unlink: If True, the operation is offloaded to the file.rename execution module function. This will use os.rename underneath, which will fail in the event that src and dst are on different filesystems. If False (the default), shutil.move will be used in order to fall back on a "copy then unlink" approach, which is required for moving across filesystems.

New in version 3006.0.

CLI Example:

salt '*' file.move /path/to/src /path/to/dst

salt.modules.file.normpath(path)¶

Returns Normalize path, eliminating double slashes, etc.

CLI Example:

salt '*' file.normpath 'a/b/c/..'

salt.modules.file.open_files(by_pid=False)¶

Return a list of all physical open files on the system.

CLI Examples:

salt '*' file.open_files
salt '*' file.open_files by_pid=True

salt.modules.file.pardir()¶

Return the relative parent directory path symbol for underlying OS

New in version 2014.7.0.

This can be useful when constructing Salt Formulas.

{% set pardir = salt['file.pardir']() %}
{% set final_path = salt['file.join']('subdir', pardir, 'confdir') %}

CLI Example:

salt '*' file.pardir

salt.modules.file.patch(originalfile, patchfile, options='', dry_run=False)¶

New in version 0.10.4.

Apply a patch to a file or directory.

Equivalent to:

patch <options> -i <patchfile> <originalfile>

Or, when a directory is patched:

patch <options> -i <patchfile> -d <originalfile> -p0

originalfile: The full path to the file or directory to be patched
patchfile: A patch file to apply to originalfile
options: Options to pass to patch.

Note

Windows now supports using patch as of 3004.

In order to use this function in Windows, please install the patch binary through your own means and ensure it's found in the system Path. If installing through git-for-windows, please select the optional "Use Git and optional Unix tools from the Command Prompt" option when installing Git.

CLI Example:

salt '*' file.patch /opt/file.txt /tmp/file.txt.patch

salt '*' file.patch C:\file1.txt C:\file3.patch

salt.modules.file.path_exists_glob(path)¶

Tests to see if path after expansion is a valid path (file or directory). Expansion allows usage of ? * and character ranges []. Tilde expansion is not supported. Returns True/False.

New in version 2014.7.0.

CLI Example:

salt '*' file.path_exists_glob /etc/pam*/pass*

salt.modules.file.prepend(path, *args, **kwargs)¶

New in version 2014.7.0.

*args: strings to prepend to the file

CLI Example:

salt '*' file.prepend /etc/motd \
        "With all thine offerings thou shalt offer salt." \
        "Salt is what makes things taste bad when it isn't in them."

Attention

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.prepend /etc/motd args='cheese=spam'

salt '*' file.prepend /etc/motd args="['cheese=spam','spam=cheese']"

salt.modules.file.psed(path, before, after, limit='', backup='.bak', flags='gMS', escape_all=False, multi=False)¶

path

The full path to the file to be edited

before

A pattern to find in order to replace with after

after

Text that will replace before

limit: ''

An initial pattern to search for before searching for before

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

flags: gMS

Flags to modify the search. Valid values are:

g: Replace all occurrences of the pattern, not just the first.
I: Ignore case.
L: Make \w, \W, \b, \B, \s and \S dependent on the locale.

salt.modules.file.remove_backup(path, backup_id)¶

This function is an alias of delete_backup.

New in version 0.17.0.

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.list_backups

CLI Example:
salt '*' file.delete_backup /var/cache/salt/minion/file_backup/home/foo/bar/baz.txt 0

salt.modules.file.rename(src, dst)¶

Rename a file or directory

CLI Example:

salt.modules.file.replace(path, pattern, repl, count=0, flags=8, bufsize=1, append_if_not_found=False, prepend_if_not_found=False, not_found_content=None, backup='.bak', dry_run=False, search_only=False, show_changes=True, ignore_if_missing=False, preserve_inode=True, backslash_literal=False)¶

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 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 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]'

salt.modules.file.restore_backup(path, backup_id)¶

New in version 0.17.0.

backup_id: The numeric id for the backup you wish to restore, as found using file.list_backups

CLI Example:

salt '*' file.restore_backup /foo/bar/baz.txt 0

salt.modules.file.restorecon(path, recursive=False)¶

Remove the specified directory. Fails if a directory is not empty.

recurse: When recurse is set to True, all empty directories within the path are pruned.

New in version 3006.0.
verbose: When verbose is set to True, a dictionary is returned which contains more information about the removal process.

New in version 3006.0.
older_than: When older_than is set to a number, it is used to determine the number of days which must have passed since the last modification timestamp before a directory will be allowed to be removed. Setting the value to 0 is equivalent to leaving it at the default of None.

New in version 3006.0.

CLI Example:

salt '*' file.rmdir /tmp/foo/

salt.modules.file.search(path, pattern, flags=8, bufsize=1, ignore_if_missing=False, multiline=False)¶

New in version 0.17.0.

Search for occurrences of a pattern in a file

Except for multiline, params are identical to replace().

before: A pattern to find in order to replace with after
after: Text that will replace before
limit: '': An initial pattern to search for before searching for before
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
options: -r -e: Options to pass to sed
flags: g: Flags to modify the sed search; e.g., i for case-insensitive pattern matching
negate_match: False: Negate the search command (!)

New in version 0.17.0.

Forward slashes and single quotes will be escaped automatically in the before and after patterns.

CLI Example:

salt '*' file.sed /etc/httpd/httpd.conf 'LogLevel warn' 'LogLevel info'

salt.modules.file.sed_contains(path, text, limit='', flags='g')¶

Deprecated since version 0.17.0: Use search() instead.
