Collect Subdomains on the Go! subs.sh is a simple bash script which automates & collects subdomains from different public APIs and saves them in a file. No additional tools are needed except jq, curl, unfurl
apt-get install golang git jq curl go get -u github.com/tomnomnom/unfurl
mv subs /usr/local/bin/subs
subs domain.com
