short_description: return a list of files based on specific criteria
description:
    - Return a list of files based on specified criteria.
    - Multiple criteria are AND'd together.
options:
    age:
        description:
            - Select files or folders whose age is equal to or greater than
              the specified time. Use a negative age to find files equal to or
              less than the specified time. You can choose seconds, minutes,
              hours, days or weeks by specifying the first letter of an of
              those words (e.g., "2s", "10d", 1w").
        required: false
    age_stamp:
        description:
            - Choose the file property against which we compare C(age). The
              default attribute we compare with is the last modification time.
        required: false
        default: mtime
        choices: ['atime', 'mtime', 'ctime']
    checksum_algorithm:
        description:
            - Algorithm to determine the checksum of a file. Will throw an error
              if the host is unable to use specified algorithm.
        required: false
        default: sha1
        choices: ['md5', 'sha1', 'sha256', 'sha384', 'sha512']
    file_type:
        description: Type of file to search for
        required: false
        default: file
        choices: ['file', 'directory']
    follow:
        description:
            - Set this to true to follow symlinks in the path. This needs to
              be used in conjunction with C(recurse).
        required: false
        default: false
        choices: ['true', 'false']
    get_checksum:
        description:
            - Whether to return a checksum of the file in the return info (default sha1),
              use C(checksum_algorithm) to change from the default.
        required: false
        default: true
        choices: ['true', 'false']
    hidden:
        description: Set this to include hidden files or folders
        required: false
        default: false
        choices: ['true', 'false']
    paths:
        description:
            - List of paths of directories to search for files or folders in.
              This can be supplied as a single path or a list of paths.
        required: true
    patterns:
        description:
            - One or more (powershell or regex) patterns to compare filenames
              with. The type of pattern matching is controlled by C(use_regex)
              option. The patterns retrict the list of files or folders to be
              returned based on the filenames. For a file to be matched it
              only has to match with one pattern in a list provided.
        required: false
    recurse:
        description:
            - Will recursively descend into the directory looking for files
              or folders
        required: false
        default: false
        choices: ['true', 'false']
    size:
        description:
            - Select files or folders whose size is equal to or greater than
              the specified size. Use a negative value to find files equal to
              or less than the specified size. You can specify the size with
              a suffix of the byte type i.e. kilo = k, mega = m... Size is not
              evaluated for symbolic links.
        required: false
        default: false
    use_regex:
        description:
            - Will set patterns to run as a regex check if true
        required: false
        default: false
        choices: ['true', 'false']
