Ansible playbook shell output

The debug module could really use some love, but at the moment the best you can do is use this:

- hosts: all
  gather_facts: no
  tasks:
    - shell: ps -eo pcpu,user,args | sort -r -k1 | head -n5
      register: ps

    - debug: var=ps.stdout_lines

It gives an output like this:

ok: [host1] => {
    "ps.stdout_lines": [
        "%CPU USER     COMMAND",
        " 1.0 root     /usr/bin/python",
        " 0.6 root     sshd: root@notty ",
        " 0.2 root     java",
        " 0.0 root     sort -r -k1"
    ]
}
ok: [host2] => {
    "ps.stdout_lines": [
        "%CPU USER     COMMAND",
        " 4.0 root     /usr/bin/python",
        " 0.6 root     sshd: root@notty ",
        " 0.1 root     java",
        " 0.0 root     sort -r -k1"
    ]
}
