如何从 bash 脚本中获取 aws 账户 ID

Question

So, I would like to obtain my aws account id through a bash script. I know that when I run aws sts get-caller-identity , it returns a json (similar to)

{
    "UserId": "JALDKKEABANMFSL:john.doe",
    "Account": "10299301874829",
    "Arn": "arn:aws:sts::10299301874829:assumed-role/admin/john.doe"
}

is there a way for my to either just get the "Account" value from the returned json? I've tried saving the response into a.json file and using jq, but that has been throwing errors. Any ideas? Thanks!!

The AWS CLI uses JMESPath to access elements of the output:

aws sts get-caller-identity --query 'Account' --output text

This will extract the Account value from the returned dictionary and output it in plain text.

JMESPath is extremely powerful. I highly recommend looking at the JMESPath Tutorial .
