Synopsis

  • Run a commandi or more and split the output into lines returning them as a list

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: we could use file direclty, but this shows output from command
  debug: msg="{{ item }} is a line running cat on /etc/motd"
  with_lines: cat /etc/motd

- name: More useful example of looping over a command result
  shell: "/usr/bin/frobnicate {{ item }}"
  with_lines:
    - "/usr/bin/frobnications_per_host --param {{ inventory_hostname }}"
