Is there a linux shell command that I can use to inspect the TXT records of a domain?
Dig will also do it quite nicely:
dig -t txt example.com and if you add the
+short option you get just the txt record in quote marks with no other cruft.
The host(1) command has a nice, terse output:
$ host -t txt google.com google.com descriptive text "v=spf1 include:_netblocks.google.com ip4:18.104.22.168/31 ip4:22.214.171.124/31 ~all" $ wajig findfile $(which host) bind9-host: /usr/bin/host $
With dig(1) I "have" to add the "+short" option all the time as well.
