Unable to redirect variable's value to file using ansible copy module

I have taken just a sample from a huge data that I wish to read from variables and dump in the file.

cat junk.txt

{:,:"(s):"}}

This data in the junk is not in my control and comes as output from a database script execution.

Below is my attempt to dump the data from junk.txt to a log file github.out and the junk data should keep getting appended to the github.out throughout my play which is something I m not able to achieve.

---

- name: "Play 1-Find the details here"

  hosts: localhost
  gather_facts: no

  tasks:

   - name: Read junk file
     raw: "cat {{ playbook_dir }}/junk.txt"
     register: junkdata

#   - name: Dump data to file
#     raw: echo "{{ junkdata.stdout }}" >> "{{ playbook_dir }}/outputjunk.txt"

   - name: Direct script execution in Standard logs for GitHub actions (TXTstdout)
     ansible.builtin.copy:
       content: ">> TXT SUCCESS OUTPUT1- {{ junkdata.stdout }}"
       dest: "{{ playbook_dir }}/github.out"
       force: no

   - name: Direct script execution in Standard logs for GitHub actions (TXTstdout)
     ansible.builtin.copy:
       content: ">> TXT SUCCESS OUTPUT2- {{ junkdata.stdout }}"
       dest: "{{ playbook_dir }}/github.out"
       force: no

The commented section if uncommented to redirected content to log file gives me the below error:

TASK [Dump data to file]

Monday 27 November 2023 10:21:22 -0600 (0:00:00.035)
0:00:00.087 *******

fatal: [localhost]: FAILED! => {"changed": true, "msg": "non-zero return code", "rc": 1, "stderr": "/bin/sh: -c: line 0: syntax error near unexpected token ('\n/bin/sh: -c: line 0: echo "{:,:"(s):"}}'\n", "stderr_lines": ["/bin/sh: -c: line 0: syntax error near unexpected token ('", "/bin/sh: -c: line 0: echo "{:,:"(s):"}}'"], "stdout": "", "stdout_lines": []}

I therefore decided to use the copy module to dump the data to a file which it does.

But I wanted each content to keep appending to github.out which it does not.

Expected / Desired output:

$ cat github.out
>> TXT SUCCESS OUTPUT1- {:,:"(s):"}}

>> TXT SUCCESS OUTPUT2- {:,:"(s):"}}

Current output:

$ cat github.out

>> TXT SUCCESS OUTPUT1- {:,:"(s):"}}

And if the github.out exists from the previous run then nothing gets appended.

Can you please suggest?

Quote raw module like below to fix the first error:

raw: "echo {{ junkdata.stdout }} >> {{ playbook_dir }}/outputjunk.txt"

copy module overwrites the content. So use lineinfile instead, with a loop like:

   - name: Direct script execution in Standard logs for GitHub actions (TXTstdout)
     loop:
         - ">> TXT SUCCESS OUTPUT1- {{ junkdata.stdout }}"
         - ">> TXT SUCCESS OUTPUT2- {{ junkdata.stdout }}"
     ansible.builtin.lineinfile:
       path: "{{ playbook_dir }}/github.out"
       create: true
       line: "{{ item }}"

$ cat github.out
>> TXT SUCCESS OUTPUT1- {:,:"(s):"}}

>> TXT SUCCESS OUTPUT2- {:,:"(s):"}}
