This is an example AWS CLI script:

taskDefs=$(aws ecs list-task-definitions --status="INACTIVE" --query="taskDefinitionArns")
echo $taskDefs
# output: ["arn:1", "arn:2", "arn:3"]

This outputs exactly the same:

echo $taskDefs[0]
# output: ["arn:1", "arn:2", "arn:3"]

I want to iterate over the results but it seems to just echo the entire array.

for value in "${taskDefs[@]}"
do
echo "value=$value" 
done
# output: value=["arn:1", "arn:2", "arn:3"]

I want it to output:

value="arn:1"

    Thankyou @ticktalk. I actually found a solution which is more elegant and suits specifically the context of the output of the aws cli. While everyone seems to be determined to close the question and associate my question with previous solutions, to use a third party tool like jq is unnecessary. aws cli output can be in text. That can be wrapped in a bash array. myarray=($(awsOutputetc --output ext)). echo $myarray[0] Commented Oct 8, 2024 at 2:30
