How to pass parameters to --query

[AkhilaGarlapally]

Hi,

1. When I try this command

aws gamelift list-builds --region us-west-2 --query 'Builds[?starts_with(Name, ` "mybuild" `) == `true`].BuildId' --output text

output: build-xxxx

2. When I try this command

$var=mybuild
aws gamelift list-builds --region us-west-2 --query 'Builds[?starts_with(Name, `"$${var}"`) == `true`].BuildId' --output text

output No Output
ExpectedOutput build-xxxx

Can you please help me how can I make second attempt success

Hi @AkhilaGarlapally, thanks for reaching out.

AWS uses JMESPath expression and it is enclosed in single quotes. In this case, you can surround the --query value with double quotes and then use single quotes (raw string literals) for the $mybuild var like so:

var=mybuild
aws gamelift list-builds --region us-west-1 --query "Builds[?starts_with(Name, '${var}')].BuildId" --output text

I was able to get the expected output with this command above. Please let me know if you're still having the issue.

Hope it helps,
John
