user89073: I accidentally created a new wallet with
$ bitcoin-cli -testnet createwallet help
{
  "name": "help",
  "warning": ""
}

Now I would like to delete it without deleting the others I already have, means without deleting the whole wallet.dat. How can I do this?

user48884: Each wallet has its own wallet.dat file as well as some other files. You can delete a wallet by deleting those files.
First go to the wallets directory. This will either be a folder named wallets inside of the data directory, or the data directory itself (there will not be a folder named wallets in that case). Inside the wallets directory will be folders each named with a wallet's name.
To delete a wallet, delete the folder in the wallets directory with the name of the wallet you want to delete (in this case, help). Note that you must delete the entire directory, leaving the directory there or any of the files it contains will result in errors.
