Oneliner: stop all running AWS step-functions for given state-machine

oneliner_aws_sfn_stop_running.md

NOTE: You will be required to have PROFILE and STATE_MACHINE_ARN set in your environment variables for the below to work. Alternatively set them as part of the oneliner.

The blow will query AWS for all RUNNING executions of your state-machine, then loop through each one sending a stop request. This will terminate the function in whatever state it happens to be in. This will NOT stop external work that has already been invoked. If you run into errors with the below, not that it is trying to run the stop command in parallel, so a smaller parallelism number may be appropriate for your use case.

$ aws --profile ${PROFILE} stepfunctions list-executions --state-machine-arn ${STATE_MACHINE_ARN} --status-filter RUNNING | grep executionArn | awk '{print $2}' | sed -e 's/\"//g' | sed -e 's/,//g' | xargs -L 1 -n 1 -P 10 aws --profile ${PROFILE} stepfunctions stop-execution --execution-arn

maybe too late, but to run this over a big list without need of accepting each output/response from aws, you can add > /tmp/output.txt to the end, like:

$ aws --profile ${PROFILE} stepfunctions list-executions --state-machine-arn ${STATE_MACHINE_ARN} --status-filter RUNNING | grep executionArn | awk '{print $2}' | sed -e 's/\"//g' | sed -e 's/,//g' | xargs -L 1 -n 1 -P 10 aws --profile ${PROFILE} stepfunctions stop-execution --execution-arn > /tmp/output.txt

that way you don't need to do anything, and it will stop all running sfn.
