How to reset blocks count in bitcoin-cli regtest?

Question

How can I reset the block count value or fully restart the regtest?

Now getblockcount command returns me a 6120.

$ bitcoin-cli getblockcount
6120

After reloading bitcoind the getblockcount value not resets to 0

Answer 1

I had to just delete the regtest subdirectory inside the .bitcoin folder

You can safely delete the regtest subdirectory and restart Bitcoin Core to start a new regtest
