How to mint Cardano native tokens

first. I did this old guide… How to mint and register Cardano tokens (native assets) - Super easy! - YouTube
It seems good. but too old version…
Then, I did Minting Native Assets | Cardano Developer Portal… I faced the problem
I used tokenname1=$(echo -n “Testtoken” | xxd -ps | tr -d ‘\n’) maybe tokenname was converted to 16 format.

Ok, do u have cntools (I remember yes)? U can mint/burn from cntools

Type ./cntools.sh -a

I have a guide on forum

I have never use cntools… In my com, cntools is not installed. can you guide it?

Aa ok, then use manuall way
