How to find the magicDNS domain name from CLI?

tailscale_jq_dnsname.md

tailscale status -json | jq -r '.Self.DNSName[:-1]'

• Requires tailscale and jq.
• [:-1] removes the tailing dot.
  There may be other options -- like choosing a different field or choosing a another command instead of jq -- but I wanted to keep it brief.
• Dicussed here, but the site is in read-only mode and may disappear. Let's hope the search results will fix themselves while I post it here.
