Append text to the end of a 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."
Check for the changes in the file metadata.
CLI Example:
salt '*' file.check_file_meta /etc/httpd/conf.d/httpd.conf salt://http/httpd.conf '{hash_type: 'md5', 'hsum': <md5sum>}' root, root, '755' base
Check if a file matches the given hash string
Returns true if the hash matched, otherwise false. Raises ValueError if the hash was not formatted correctly.
CLI Example:
salt '*' file.check_hash /etc/fstab md5=<md5sum>
Check to see what changes need to be made for a file
CLI Example:
salt '*' file.check_managed /etc/httpd/conf.d/httpd.conf salt://http/httpd.conf '{hash_type: 'md5', 'hsum': <md5sum>}' root, root, '755' jinja True None None base

CLI Example:
salt '*' file.check_perms /etc/sudoers '{}' root root 400
Change the group of a file
CLI Example:
salt '*' file.chgrp /etc/passwd root
Chown a file, pass the file the desired user and group

New in version 0.9.5.
Comment out specified lines in a file
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
New in version 0.9.5.
Return True if the file at path contains text

salt '*' file.contains_glob /etc/foobar '*cheese*'
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 Examples:
salt '*' file.contains_regex /etc/crontab
Return True if the given regular expression matches anything in the text of a given file
Traverses multiple lines at a time, via the salt BufferedReader (reads in chunks)
CLI Example:
salt '*' file.contains_regex_multiline /etc/crontab '^maint'
Tests to see if path is a valid directory. Returns True/False.
CLI Example:
salt '*' file.directory_exists /etc
Tests to see if path is a valid file. Returns True/False.
CLI Example:

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
iregex = path-regex # case insensitive
type = file-types # match any listed type
user = users # match any listed user
group = groups # match any listed group
size = [+-]number[size-unit] # default unit = byte
mtime = interval # modified since date
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]
The default action is 'print=path'.
file-glob:
* = match zero or more chars
? = match any char
[abc] = match a, b, or c
[!abc] or [^abc] = match anything except a, b, and c
