Ansible PLaybook: Escape '$' in Linux path - ansible

Question

I have a path which looks like this -
base_dir/123/path/to/G\$/subdirectory/html/
When I try to set this path in Ansible playbook, it throws error. If add \$ to escape '\', it throws unexpected failure error.
Playbkook -
- hosts: localhost
vars:
account_id: 123
tasks:
- name: Add \ to path
debug:
var: "base_dir/{{ account_id }}/path/to/G\\$/subdirectory/html/"
Result -
TASK [Gathering Facts] *************************************************************************************************************************************************
task path: /playbooks/example_path.yml:2
ok: [localhost]
META: ran handlers
TASK [Add \ to path] ***************************************************************************************************************************************************
task path: /playbooks/exmaple_path.yml:6
fatal: [localhost]: FAILED! => {
"msg": "Unexpected failure during module execution."
}
PLAY RECAP *************************************************************************************************************************************************************
localhost : ok=1 changed=0 unreachable=0 failed=1

As explained in the debug module documentation, the var option is expecting a variable name, not a scalar for output. You are getting an error because \ is not expected in a variable name. Running the playbook with -vvv will give you a little more explanations.
In this case you need to use the msg option.
- hosts: localhost
gather_facts: false
vars:
account_id: 123
tasks:
- name: Add \ to path
debug:
msg: "base_dir/{{ account_id }}/path/to/G\\$/subdirectory/html/"
Result
PLAY [localhost] ***************************************************************
TASK [Add \ to path] ***********************************************************
ok: [localhost] => {
"msg": "base_dir/123/path/to/G\\$/subdirectory/html/"
}
PLAY RECAP *********************************************************************
localhost : ok=1 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

The next option is to use the Single-Quoted Style. See the example below
- hosts: localhost
vars:
my_dir1: "/scratch/tmp/G1\\$"
my_dir2: '/scratch/tmp/G2\$'
tasks:
- file:
state: directory
path: "{{ item }}"
loop:
- "{{ my_dir1 }}"
- "{{ my_dir2 }}"
# ls -1 /scratch/tmp/
'G1\$'
'G2\$'
