Hi Malik,

If you see the error message, it seems it has wrongly interpret the command you issue, from which some characters are gone (tx --tls ). No idea why this happens. Can you make sure the command is typed correct?

Also you can check whether the files exist, by

ls /opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts/

And you should see the file channelall.tx and channel12.tx if you follow the steps.

HTH.
