Hi. Im having trouble in my backup test playbook. backed up files are is Amazon s3 bucket. The problem is - we have many versions there. i need to **limit rsync to latest version without providing it manually** , or to prompt me for choice. At the moment im stuck. **I fail to find a module which could help me.** - name: List s3 objects aws\_s3: bucket: “bucket\_name” prefix: “application\_folder” max\_keys: 3 \*(application has 3 files in it so im trying to limit to the last 3 - unnsuccesfully though. ) mode: list register: s3objects become: yes become\_user: username - debug: var=s3objects - name: write to file copy: content: “{{ s3objects }}” dest: /home/username/application\_folder\_version mode: 0644 force: yes with\_items: s3objects become: yes become\_user: username outcome: “application/2018-08-21/1.78/application.properties”, “application/2018-08-21/1.78/run.sh”, “application/2018-08-21/1.78/application.jar”, “application/2018-08-22/1.79/application.properties”, “application/2018-08-22/1.79/run.sh”, “application/2018-08-22/1.79/application.jar”, “application/2018-08-30/1.80/application.properties”, “application/2018-08-30/1.80/run.sh”, “application/2018-08-30/1.80/application.jar”, “application/2018-09-06/1.81/application.properties”, “application/2018-09-06/1.81/run.sh”, “application/2018-09-06/1.81/application.jar”, “application/2018-09-07/1.81/application.properties”, “application/2018-09-07/1.81/run.sh”, “application/2018-09-07/1.81/application.jar”, “application/2018-09-17/1.82/application.properties”, “application/2018-09-17/1.82/run.sh”, “application/2018-09-17/1.82/application.jar”, “application/2018-10-11/1.83/application.properties”, “application/2018-10-11/1.83/run.sh”, “application/2018-10-11/1.83/application.jar”, “application/2018-10-16/1.84/application.properties”, “application/2018-10-16/1.84/run.sh”, “application/2018-10-16/1.84/application.jar”, “application/2018-10-18/1.85/application.properties”, “application/2018-10-18/1.85/run.sh”, “application/2018-10-18/1.85/application.jar”, “application/2018-10-25/1.86/application.properties”, “application/2018-10-25/1.86/run.sh”, “application/2018-10-25/1.86/application.jar”, “application/2018-10-31/1.87/application.properties”, “application/2018-10-31/1.87/run.sh”, “application/2018-10-31/1.87/application.jar”, “application/2018-11-07/1.88/application.properties”, “application/2018-11-07/1.88/run.sh”, “application/2018-11-07/1.88/application.jar” I could read last 3 lines from a file and take them as variables, but i don´t see how to do it with ansible. Thanks for reading. ---

Maybe restructure the tasks and take a single file into account, so that you can simple sort and pick the last one. Then iterate over each of the 3 files. Dick ---

> im still in trouble with even a single file, because of the directory structure. The folder with a date is generated automatically and i wont know it in advance. meaning “application/2018-10-31/1.87/application.properties”, “application/2018-10-31/1.87/run.sh”, “application/2018-10-31/1.87/application.jar”, “application/2018-11-07/1.88/application.properties”, “application/2018-11-07/1.88/run.sh”, “application/2018-11-07/1.88/application.jar” application/Foldernamechanges/versionnamechanges/static.jar ---

You have left out a lot of useful information, I have never user aws\_s3 so I don't know it's structure. But to get the 3 last elements in a list it's just \[-3]
