Ekk :
I would like to delete all old files, and keep newest 4 files. The output isn't what i expected. Even i use absent on file modules, but it doesn't delete the files.
My files are here
# ls -l /home/tomcat/backup
total 0
-rw-r--r-- 1 root root 0 Mar 3 14:21 1
-rw-r--r-- 1 root root 0 Mar 3 14:21 2
-rw-r--r-- 1 root root 0 Mar 3 14:21 3
-rw-r--r-- 1 root root 0 Mar 3 14:21 4
-rw-r--r-- 1 root root 0 Mar 3 14:21 5
-rw-r--r-- 1 root root 0 Mar 3 14:21 6
-rw-r--r-- 1 root root 0 Mar 3 14:21 as
-rw-r--r-- 1 root root 0 Mar 3 14:21 asd
-rw-r--r-- 1 root root 0 Mar 3 14:21 df
-rw-r--r-- 1 root root 0 Mar 3 14:21 fas
-rw-r--r-- 1 root root 0 Mar 3 14:21 y6
ansible.yml
- name: Prerequsite Deployement | Get first 4 files
shell: "ls -t {{ item.path }}/{{ item.filename }} | tail -n +4"
with_items:

register: files_matched
tags: prerequsite_deployment
- debug:

- name: Prerequsite Deployement | Clean up path
file:
path: "{{item.stdout_lines}}"
state: absent
with_items:
- "{{files_matched.results}}"

the result ouput
# ls -l /home/tomcat/backup
total 0
-rw-r--r-- 1 root root 0 Mar 3 14:21 1

My expected result output
# ls -l /home/tomcat/backup
total 0
-rw-r--r-- 1 root root 0 Mar 3 14:21 1
-rw-r--r-- 1 root root 0 Mar 3 14:21 2

-rw-r--r-- 1 root root 0 Mar 3 14:21 4
Vladimir Botka :
The attribute mtime
in the dictionaries listed in the registered result.files
can be used to sort the files. For example
- find:
paths: dir1
recurse: true
register: result
- set_fact:
my_files: "{{ result.files|
sort(attribute='mtime')|
map(attribute='path')|
list }}"
Optionally list the files but the last (newest) 4 files
- debug:
var: item
loop: "{{ my_files[0:-3] }}"
Delete the files if this is what you want
- file:
state: absent
path: "{{ item }}"
loop: "{{ my_files[0:-3] }}"
