If you get an error exec format error: ./subzy, you need to install Golang for your OS and compile the program by running go build -o subzy main.go which will generate new subzy binary file

Only required flag for run subcommand(r short version) is either --target or --targets

--target (string) - Set single or multiple (comma separated) target subdomain/s
--targets (string) - File name/path to list of subdomains
--concurrency (integer) - Number of concurrent checks (default 10)
--hide_fails (boolean) - Hide failed checks and invulnerable subdomains (default false)
--https (boolean) - Use HTTPS by default if protocol not defined on targeted subdomain (default false)
--timeout (integer) - HTTP request timeout in seconds (default 10)
--verify_ssl (boolean) - If set to true, it won't check site with invalid SSL

Target subdomain can have protocol defined, if not http:// will be used by default if --https not specifically set to true.

• List of subdomains

  • ./subzy run --targets list.txt

• Single or multiple targets

  • ./subzy run --target test.google.com
  • ./subzy run --target test.google.com,https://test.yahoo.com

Each subzy subcommand has its own short version. Running subzy version or subzy v is the same.
