Hi,

Ansible newbie here.

A very basic playbook.

---
- hosts: '{{ target }}'
  gather_facts: no
  su: yes
  su_user: root

  tasks:
  - name: test listing files
    command: ls

results in the following error. I've set the 'executable = /usr/bin/bash' as an --extra-var but no luck. It errors out with the same error with the default of '/bin/sh'

Any pointers would be greatly appreciated.
