# List TXT DNS Records For A Domain
The `dig` command can be used to list specifically the `TXT` DNS records for a
domain using the `-t TXT` flag like so:
```bash
$ dig -t TXT visualmode.dev
; <<>> DiG 9.10.6 <<>> -t TXT visualmode.dev
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 41226

visualmode.dev. 377 IN TXT "v=spf1 include:_spf.mx.cloudflare.net ~all"
visualmode.dev. 377 IN TXT "google-site-verification=MBZ2S2fhnh2gHRxFniRrYW-O6mdyimJDRFj-f
vblwtk"

```
This is still rather verbose though. With the `+short` option we can pare down
the output to the values of any TXT records and nothing else.
```bash
$ dig -t TXT visualmode.dev +short
"v=spf1 include:_spf.mx.cloudflare.net ~all"
"google-site-verification=MBZ2S2fhnh2gHRxFniRrYW-O6mdyimJDRFj-fvblwtk"
```
Neat! Now I can see that [my domain is correctly identifying itself with Google
Search Console](internet/verify-site-ownership-with-dns-record.md).
