#Bash one liner: Get a specific #DNS record entry line #LetsEncrypt

By | November 2, 2021

Another bash one liner that saved my sanity.

While generating site wide certificates from LetsEncrypt you have to check if a certain TXT key was added to the DNS record (_acme-challenge).

Here is the magic line that returns only that for my domain “voina.fr”.

❯ dig -t txt _acme-challenge.voina.fr +short

So when waiting to see if the DNS TXT record was propagated so you can continue with the certificate challenge, just run the above line in a terminal.
