Pass data to a Stack Script using 'linode-cli'?

We're moving from the deprecated Linode CLI tool to the new "linode-cli", and I'm having issues trying to figure out how to pass the required data into a call to rebuild a linode using a stackscript.
Can you provide an example of how to format the data like "fqdn" into the stackscript_data parameter?

In order to pass data to the --stackscript_data parameter in the current linode-cli, you can use a command following the basic form:
linode-cli linodes create \
--label linode123 \
--root_pass aComplex@Password \
--booted true \
--stackscript_id 10079 \
--stackscript_data '{"gh_username": "linode"}' \
--region us-east \
--type g6-standard-2 \
--authorized_keys "ssh-rsa AAAA_valid_public_ssh_key_123456785== user@their-computer"
The relevant line here is --stackscript_data '{"gh_username": "linode"}' \ and you should be able to substitute "gh_username" with the name of the value you are passing data to (e.g. 'fqdn') and "linode" with the data you are passing (e.g. 'www.example.com'). It is worth noting that the '\' at the end of each line is only necessary if you are breaking the command up into multiple lines, but you could also format it as:
linode-cli linodes create --label linode123 --root_pass aComplex@Password --booted true --stackscript_id 10079 --stackscript_data '{"gh_username": "linode"}' --region us-east --type g6-standard-2 --authorized_keys "ssh-rsa AAAA_valid_public_ssh_key_123456785== user@their-computer"
I recommend using the former format for the sake of readability, particularly if writing the command into a script, as it will dramatically simplify any troubleshooting/debugging later on if you find that the script contains errors.
