Minting Native tokens

Make sure you have done steps in previous chapter.
Generate protocol parameters
Generate protocol parameters and store it in ./protocol-parameters file:
cardano-cli query protocol-parameters \
  --testnet-magic $TESTNET_MAGIC \
  --out-file ./protocol-parameters
Generate key hash
Generate key hash and store it in ./key-hash file:
cardano-cli address key-hash \
    --payment-verification-key-file ./verification-key \
    > ./key-hash
Print your key hash to console:
cat ./key-hash
Create minting policy
Create minting policy file:
touch minting-policy
Add following lines to minting-policy file, where your_key_hash is the key hash generated above:
{
  "keyHash": "your_key_hash",
  "type": "sig"
}
Generate policy ID, and store it in ./minting-policy-id file:
cardano-cli transaction policyid \
  --script-file ./minting-policy \
  > ./minting-policy-id
Define your token name and amount
We are gonna define our token name and the amount we want to mint, please replace your_token_name and your_token_amount to your token name and minting amount. 
export TOKEN_NAME=your_token_name
export TOKEN_AMOUNT=your_token_mount
Build transaction
Run this command to query the utxo in your address:
cardano-cli query utxo \
    --address $(< ./address) \
    --testnet-magic $TESTNET_MAGIC
You should get something like this:
                           TxHash                                 TxIx        Amount

we need to store these values in the environment variables so we can use it later, please replace the_tx_hash , the_tx_ix and the_amount to the TxHash, TxIx and Amount printed on your console:
export TX_HASH=the_tx_hash
export TX_IX=the_tx_ix
export TX_AMOUNT=the_amount
Build raw transaction:
cardano-cli transaction build-raw \
  --fee 0 \
  --tx-in $TX_HASH#$TX_IX \
  --tx-out $(< ./address)+$TX_AMOUNT+"$TOKEN_AMOUNT $(< ./minting-policy-id).$TOKEN_NAME" \
  --mint="$TOKEN_AMOUNT $(< ./minting-policy-id).$TOKEN_NAME" \
  --out-file tx.raw
Calculate the minimum fee for this transaction:
cardano-cli transaction calculate-min-fee \
  --tx-body-file tx.raw \
  --tx-in-count 1 \
  --tx-out-count 1 \
  --witness-count 1 \
  --testnet-magic $TESTNET_MAGIC \
  --protocol-params-file ./protocol-parameters
For me, I got the output 174785 Lovelace, I'm gonna set the TX_FEE to 174785, you need to set it to the integer value printed on your console:
export TX_FEE=the_tx_fee
Now rebuild the transaction with fee:
cardano-cli transaction build-raw \
  --fee $TX_FEE \
  --tx-in $TX_HASH#$TX_IX \
  --tx-out $(< ./address)+$(($TX_AMOUNT - $TX_FEE))+"$TOKEN_AMOUNT $(< ./minting-policy-id).$TOKEN_NAME" \
  --mint="$TOKEN_AMOUNT $(< ./minting-policy-id).$TOKEN_NAME" \
  --out-file tx.raw
Sign and submit the transaction
Sign this transaction:
cardano-cli transaction sign \
  --tx-body-file tx.raw \
  --signing-key-file ./signing-key \
  --script-file ./minting-policy \
  --testnet-magic $TESTNET_MAGIC \
  --out-file tx.signed
Submit the transaction:
cardano-cli transaction submit \
  --tx-file  tx.signed \
  --testnet-magic $TESTNET_MAGIC
Now, recheck funds in our address:
cardano-cli query utxo \
    --address $(< ./address) \
    --testnet-magic $TESTNET_MAGIC
The output I got:
                           TxHash                                 TxIx        Amount

Great! Now we minted our own token! 😀🎉🎉🎉
