Parameters

Parameter	Choices/Defaults	Configuration	Comments
_terms - / required			command(s) to run

Notes

Note

• Like all lookups this runs on the Ansible controller and is unaffected by other keywords, such as become, so if you need to different permissions you must change the command or run Ansible as another user.
• Alternatively you can use a shell/command task that runs against localhost and registers the result.

Examples

- name: raw result of running date command"
  debug: msg="{{ lookup('pipe','date') }}"

- name: Always use quote filter to make sure your variables are safe to use with shell
  debug: msg="{{ lookup('pipe','getent ' + myuser|quote ) }}"

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
