Use case: adding [bash-completion](https://github.com/bobthecow/git-flow-completion/wiki/Install-Bash-git-completion) to dev-environment playbook.

In OSX, I need to write to either `.profile` or `.bash_profile` via Ansible. I need to add some config lines to one of those files and would like to do so to whichever one exists. I need to add those lines to the first of those files that exists since [OSX looks for `.bash_profile`, `.bash_login`, then `.profile` and stops looking when it finds one of them](https://stackoverflow.com/questions/18773051/how-to-make-os-x-to-read-bash-profile-not-profile-file).

Is there an environment variable I can use to determine which file was used to load the bash config?

Is there a way to create a variable in Ansible that tells Ansible which of those files to write to, depending on the first one in the list (`.bash_profile`, `.bash_login`, `.profile`) that exists?

I've tried this in my existing `playbook.yml`, which does not overwrite my initially stated var of "bash\_config":

```
    - hosts: localhost
      connection: local
      vars:
        bash_config: "{{ ansible_user_dir }}/.profile"

      tasks:
        - stat: path="{{ ansible_user_dir }}/.profile"
          register: bash_config
          when: bash_config.exists = true
        - stat: path="{{ ansible_user_dir }}/.bash_login"
          register: bash_config
          when: bash_config.exists = true
        - stat: path="{{ ansible_user_dir }}/.bash_profile"
          register: bash_config
          when: bash_config.exists = true

```
