If set to false, an exception will be raised if more than one line matches. Valid options: 'true', 'false'. Default: Undefined. * `name`: Sets the name to use as the identity of the resource. This is necessary if you want the resource namevar to differ from the supplied `title` of the resource. Valid options: String. Default: Undefined. * `path`: **Required.** Defines the file in which Puppet will ensure the line specified by `line`. Must be an absolute path to the file. +* `replace`: Defines whether the resource will overwrite an existing line that matches the `match` parameter. If set to false and a line is found matching the `match` param, the line will not be placed in the file. Valid options: true, false, yes, no.
