Help

$ theharvester -h

Simple usage

$ theharvester -d medium.com -l 10 -b all

This command searchs for medium domain with 10 results and all available data sources.

Other options allow us to restrict the source data, use Google Dorking, save output to external file, etc.

The Harvester is another great tool to have in our toolbelt for ethical hacking.
