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:

CLI Example:

        "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)¶

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)¶

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 a line as the end 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
content: The content to be used between the two lines identified by marker_start and marker_stop.
append_if_not_found: If markers are not found and set to True then, the markers and content will be appended to the file.
prepend_if_not_found: If markers are not found and set to True then, the markers and content will be prepended to the file.
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: Don't make any edits to the file.
show_changes: Output a unified diff of the old file and the new file. If False, return a boolean if any changes were made.

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

char: The character to be inserted at the beginning of a line in order to comment it out
backup: 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.

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)¶

CLI Example:

salt '*' file.contains_regex_multiline /etc/crontab '^maint'

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

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='')¶

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 lay out rules. It specifically permits pulling hash codes from debian *.dsc files.

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

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.

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"

CLI Examples:

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

:.bakThe 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.
M: Treat multiple lines as a single line.
S: Make . match all characters, including newlines.
U: Make \w, \W, \b, \B, \d, \D, \s and \S dependent on Unicode.
X: Verbose (whitespace is ignored).

multi: False

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)¶

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 returnd 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
pattern: A regular expression, to be matched using Python's search().
repl: The replacement text
count: 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. 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: 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: 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: The file extension to use for a backup of the file before editing. Set to False to skip making a backup.
dry_run: 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: 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: 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: 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: 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).

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]'
