This is a blog post where I share various commands for use in the terminal. Mostly, I add new commands here when I find them and when someone shares something useful with me. This blog post helps me keep all these commands in a single place.
This command is useful when troubleshooting DNS issues. This was shared with me by Daniel Olson.
dig A domain.com +short dig A www.domain.com +short dig CNAME domain.com +short dig CNAME www.domain.com +short
Find Nameserver Details
These short commands were shared with me by the coffee-loving Jan Dembowski.
dig ns domain.com
dig ns domain.com +trace
Get TXT Records for a Domain
The following command is a clean way to get the basics on TXT records, which is helpful when looking to verify authorization over a domain.
dig -t txt example.com +short
I can’t recall the value of this but I used it once and it was pretty helpful. I think Daniel Olson shared this with me as well.
curl -I https://www.domain.com/

I found this wonderful technique in a blog post and copied it here for my own future reference.
