Find filename in Ansible and Save to a file - ansible

Question

How can I take filename from a specific directory and use it as a variable?
Then I'll use this variable to copy a new file with variable filename
For example: In the directory /home/user1/test/ there is always only one file named test1 or some other name.
I need to extract the filename (test1) from this path to some variable
- hosts: linux
become: yes
tasks:
- name: Ansible find file examples
find:
paths: /home/user1/test/
register: files_matched
- debug:
msg: "{{ files_matched.files }}"
- name: "Save find results to file"
copy:
content: "{{ files_matched.files }}"
dest: "/tmp/find_result.txt"
Then I've should get "test1" as variable and use it in the new filename in this code:
copy:
src: /home/myuser/myfile
dest: "{{ item.dest }}"
owner: root
group: root
mode: 0666
with_items:
- { dest: '/home/user2/test/{{ files_matched }}' }
As result of first script i've got:
: 0, "ischr": false, "wusr": true, "xoth": false, "islnk": false, "nlink": 1, "issock": false, "rgrp": true, "gr_name": "root", "path": "/home/user1/test/test1", "xusr":
false, "atime": 1564553299.6092095, "isdir": false, "ctime": 1564553304.7172158, "isblk": false, "xgrp": false, "dev": 2050, "wgrp": false, "isfifo": false, "mode": "0644
", "rusr": true}]
But i need only test1 part as result, not this all.
Thank you!

Q: "How can I take filename from a specific directory and use it as a variable?'
A: Given the tree
$ tree /home/user1/test/
/home/user1/test/
├── test1
├── test2
└── test3
the tasks below
- find:
paths: /home/user1/test/
register: files_matched
- debug:
msg: "{{ '/home/user2/test/' ~ item|basename }}"
loop: "{{ files_matched.files|json_query('[*].path') }}
give
"msg": "/home/user2/test/test1"
"msg": "/home/user2/test/test3"
"msg": "/home/user2/test/test2"

I hope you are expecting something like this. this will save the list of files under the specified directory into the /tmp/find_result.txt. I hope from here you can proceed.
---
- name: find file
hosts: linux
tasks:
- name: Ansible find file examples
find:
paths: /home/user1/test/
register: files_matched
- name: "Save find results to file"
lineinfile:
line: "{{ item.path }}"
path: "/tmp/find_result.txt"
create: yes
loop: "{{ files_matched.files | flatten }}"
note: make sure that you delete the /tmp/find_result.txt once your task completed.
if you want to store only the filename not the entire path, then replace line: "{{ item.path }}" with line: "{{ item.path | basename }}"
