Deleting All Records of a Cloudflare Zone​

danger

This will irreversibly remove all DNS records of the zone. If you have anything important on the zone, you better import all your DNS records in a Terraform state with cf-terraforming, create a backup of the Terraform resources and make this kind of change via Terraform

I made a mistake of selecting "Import all DNS records" for a new domain I purchased from another places, which resulted in more than 700 records to be imported. Cloudflare UI doesn't have bulk edit/remove functionality so I created this short script to delete all records as I didn't have any important records on the zone.

CLOUDFALRE_API_EMAIL=""
CLOUDFALRE_API_KEY=""
CLOUDFALRE_ZONE_ID=""

# List all dns records

while true; do
  dns_records=$(curl -s --fail -X GET "https://api.cloudflare.com/client/v4/zones/$CLOUDFALRE_ZONE_ID/dns_records" \
    -H "X-Auth-Email: $CLOUDFALRE_API_EMAIL" \
    -H "X-Auth-Key: $CLOUDFALRE_API_KEY" \
    -H "Content-Type: application/json")
  total_count=$(echo $dns_records | jq -r '.result_info.total_count')
  if [ $total_count -eq 0 ]; then
    break
  fi

  # loop over dns records
  echo "$dns_records" | jq -cr '.result[]' | while read -r dns_record; do
    dns_record_id=$(echo $dns_record | jq -r '.id')
    dns_record_name=$(echo $dns_record | jq -r '.name')
    dns_record_content=$(echo $dns_record | jq -r '.content')

    # delete dns record
    echo "Deleting dns record $dns_record_name with id $dns_record_id and content $dns_record_content"
    curl -s --fail -X DELETE "https://api.cloudflare.com/client/v4/zones/$CLOUDFALRE_ZONE_ID/dns_records/$dns_record_id" \

Extract Transcript as Text​

You need yt-dlp for this:

$YOUTUBE_LINK=""

yt-dlp --skip-download --write-subs --write-auto-subs --sub-lang en --sub-format ttml --convert-subs srt --output "transcript.%(ext)s" "$YOUTUBE_LINK"\
&& sed -i '' -e '/^[0-9][0-9]:[0-9][0-9]:[0-9][0-9].[0-9][0-9][0-9] --> [0-9][0-9]:[0-9][0-9]:[0-9][0-9].[0-9][0-9][0-9]$/d' -e '/^[[:digit:]]\{1,3\}$/d' -e 's/<[^>]*>//g' ./transcript.en.srt\
&& sed -e 's/<[^>]*>//g' -e '/^[[:space:]]*$/d' transcript.en.srt > output.txt\
&& rm transcript.en.srt

Merge Collections​

This script would effectively move all links from one collection to another, leaving links in the sub collections of the source collection intact.

next_cursor=""
while true; do

    "$LINKWARDEN_HOST/api/v1/search?collectionId=$SOURCE_COLLECTION_ID&type=url&limit=100&cursor=$next_cursor")

  batch_update_payload="{\"links\": $(echo "$search_results" | jq -c '[.data.links[] | { "id": .id }]'),\"newData\": {\"collectionId\": $DESTINATION_COLLECTION_ID, \"tags\": []}, \"removePreviousTags\": false}"

  echo "The following links will be updated:"
  echo "$search_results" | jq '[.data.links[] | { "id": .id, "name": .name, "url": .url }]'

  curl --silent --fail -X PUT -H "Authorization: Bearer $LINKWARDEN_ACCESS_TOKEN" \
    -H "Content-Type: application/json" \
    -d "$batch_update_payload" \
    "$LINKWARDEN_HOST/api/v1/links"

  echo " - Done"

  next_cursor=$(echo "$search_results" | jq -r '.data.nextCursor // empty')

  if [ -z "$next_cursor" ]; then
    break
  fi
done

echo "Done"
