Is there a way, by using bitcoin-cli using RPC querying, if the node I'm querying is running on MainNet or TestNet?

Thanks

Since version 0.16.0

$ bitcoin-cli getblockchaininfo

{
  "chain": "main",
  "blocks": 525663,
  "headers": 525663, 
  .
  .
  .

}

    as @Kerem atam said, you can use getblockchaininfo as well as getnetworkinfo and getwalletinfo for some more information. Nov 12 '19 at 11:29
