What does the shell script do ?

It is a collection of Harmony Pangaea Node commands to find

1. Node Block number
2. Wallet Balance
3. When did my node last sync/get the bingo message?
4. Which Shard does my node belong to?
5. Is my Shard Online?

How do I run them ?

Login to your server and issue the following commands (They are commands to get the file, give it execute privileges and execute!)

curl -LO https://raw.githubusercontent.com/mirrormirage0/pangaens/master/check_pangaea.sh
chmod u+x check_pangaea.sh
./check_pangaea.sh

Does Harmony team publish status of Shards and the latest block number for each Shard?

Yes, you can find it here https://harmony.one/pga/network
