Steem for script kiddies: Top N pending powerdowns

Just for fun, I slapped together a little toy bash script tonight to pull down the top pending power-downs for the following week. It runs from the linux command line and has been tested in ubuntu and OpenSUSE, including ubuntu under WSL.

By default, it shows the top 5 pending powerdowns from each day. To show a different number, just run with the preferred number as the first command line argument.

Note that curl, jq, and perl are required.

#!/bin/bash

N=${1:-5}

VESTING_FUND_STEEM=$(curl -s --data '{"jsonrpc":"2.0", "method":"condenser_api.get_dynamic_global_properties", "params":[], "id":1}' https://api.steemit.com | jq -Scr '.result | ( .total_vesting_fund_steem )' | awk '{print $1}')
VESTING_FUND_VESTS=$(curl -s --data '{"jsonrpc":"2.0", "method":"condenser_api.get_dynamic_global_properties", "params":[], "id":1}' https://api.steemit.com | jq -Scr '.result | ( .total_vesting_shares )' | awk '{print $1}')
STEEM_PER_MVEST=$(perl -e "print ${VESTING_FUND_STEEM} / (1000000 * ${VESTING_FUND_VESTS})")

for DAYS in 0 1 2 3 4 5 6 7
do
   date
   PDOWN_DATE=$(date -d "+${DAYS} days" +%Y-%m-%d)
   CMD='{"jsonrpc":"2.0", "method":"database_api.list_accounts", "params": {"start":["'${PDOWN_DATE}'T00:00:00", ""], "limit":1000, "order":"by_next_vesting_withdrawal"}, "id":1}'
   echo "Looking for powerdowns on ${PDOWN_DATE}"
   echo ----
   curl -s --data "${CMD}" https://api.steemit.com| \
      jq -Sc '.result[][] | {name, next_vesting_withdrawal, vesting_withdraw_rate}' | \
      egrep "${PDOWN_DATE}" | \
      awk -F, '{print $1" "$2" "$3" "$5 "--- " $4}'  | \
      sed 's/ \"precis.*//g' | \
      sed 's/\"//g' | \

      sort +0 -1nr | \
      awk '{print $2 " - " $1 " VESTS, " '${STEEM_PER_MVEST}' * $1" STEEM"}' | \
      head -${N}
      echo ; echo
done

exit

And here's some sample output:
