Get sorted list of folders with Ansible

Interesting solutions, thanks a lot guys. But I think I have found the easiest way in Ubuntu, just using ls -v /releases/ will apply natural sorting to all folders:

- name: List of releases in ascendent order  
  command: ls -v /releases/
  register: releases

- debug: msg={{ releases.stdout_lines }}

The response is:

ok: [my.remote.com] => {
    "msg": [
        "0.0.0",
        "0.0.1",
        "0.0.10",
        "1.0.0",
        "1.0.5",
        "2.0.0"
    ]
}

If you want to find files older than a period, maybe age and age_stamp parameters of find module can help you. For example:

# Recursively find /tmp files older than 4 weeks and equal or greater than 1 megabyte
- find: paths="/tmp" age="4w" size="1m" recurse=yes

You can sort items with sort filter:

- hosts: localhost
  gather_facts: no
  tasks:
    - find: path="/tmp" patterns="test*"
      register: files

    - debug: msg="{{ files.files | sort(attribute='ctime') | map(attribute='path') | list }}"

Just change sort attribute to your need.
But beware that string sort is not numeric, so /releases/1.0.5 will go after /releases/1.0.10.
