    The below will:

    1. Get all the tasks in the cluster
    2. Select the task arns using jq, -r removes the quotes from the json value.
    3. Pass each arn to the next command using xargs, the value is appended to the command (after --task). n-1 just ensures there is one command per arn, not sure if necessary.

    aws ecs list-tasks --cluster "$ecs_cluster" | jq -r ".taskArns[]" | xargs -n1 aws ecs stop-task --no-cli-pager --cluster "$ecs_cluster" --task

    --no-cli-pager prevents the output from stop-task from getting stuck after each execution.

    Any optimization welcome. I saw another solution with awk but found it hard to use with passing extra params to the second command.

    I was trying to get Baron’s answer to work and found that it needed an adjustment to work in my AWS CodeBuild (Ubuntu) use case by pulling the task id out of the ARN:

    aws ecs list-tasks --cluster "${clustername}" | jq -r ".taskArns[] | split("/")[2]" | xargs -n1 aws ecs stop-task --no-cli-pager --cluster "${clustername}" --task

    You might also want to stop all tasks for only one service

    aws ecs list-tasks --cluster "${clustername}" --service "${servicename}" | jq -r ".taskArns[] | split("/")[2]" | xargs -n1 aws ecs stop-task --no-cli-pager --cluster "${clustername}" --task
