 ### Field Filters
 
-`-f, -field` flag can be used to indicate which fields to return, currently, `ip`, `port`, and `host` are supported and can be used to return desired fields.

 ### Field Formatting
 
-**uncover** has a `-f, -field` flag that can be used to customize the output format. For example, in the case of `uncover -f https://ip:port/version`, ip:port will be replaced with results in the output while keeping the format defined, It can also be used to specify a known scheme/path/file in order to prepare the output so that it can be immediately passed as input to other tools in the pipeline.
