daml script --dar epamcoins-0.1.0.dar --script-name Test.Setup:setup --participant-config participant.json

Hello @Joy_K

1. Daml scripts are executed on your terminal, outside of the canton console.

2. What exactly are you trying to list? For parties, you can use the command, “participant1.parties.list()”

Here is a following example of how to add the option for an output file of your script.
daml script --dar .daml/dist/script-example-0.0.1.dar --script-name ScriptExample:allocateParties --ledger-host localhost --ledger-port 6865 --output-file participant.json

Once the results of the given --script-name is written into the output file, you may use the following example to use the output file:
daml script --dar .daml/dist/script-example-0.0.1.dar --script-name ScriptExample:initialize --ledger-host localhost --ledger-port 6865 --input-file participant.json

More information regarding running scripts can be found in the documentation below:
https://docs.daml.com/daml-script/index.html#run-a-script

Hope this helps!
