Can AWS Step function async run bash script?

Question

I have a step function which defined with jobs definition in java.

I wanna add an async run bash script which trying to move the data from efs to s3 bucket. What I did: 1. Login the the ec2 instance which has efs data mounted; 2. run the data move bash script;

The disadvantage of it is I need daily manually run this script. So, I wanna know if there is a way to run this script from step function since all the efs data are generated from the job submitted to this step function.

Can you clarify? You want to run a script on some instance(s) based on a trigger from step function? — Marcin

You cannot directly however the following should work for you:

Step to call a Lambda function
Have Lambda run a Systems Manager Run Command
Wait for run command to be completed successfully, before returning success or error.

Either write your own Run Command Document or instead take a look at AWS-RunShellScript document.
