don't print statement if "command not found" and compare variable value with list of values

[moisset...@gmail.com]

i'm trying this in a playbook:

..
vars:
   actionTodo: "{{ variable_actionTodo }}"
   servicesList: "{{ variable_servicesList }}"
   actionTodo_list: [start,stop,rstart,rstop,status,rstatus]
..

 - name: manage services using systemctl
    tags:  manage services using systemctl
    shell:  systemctl {{actionTodo}} {{servicesList}}
    with_items:
      - "{{servicesList}}"
    when: actionTodo != "" and  servicesList != ""
    ignore_errors: true
    register: p2


  - debug:
      var: p2

i'd like to compare:
- actionTo value with value from actionTo_list
- and avoid printing "command not found"  node without systemctl

I'd suggest not using the `shell:` module, instead use the `systemd:` module.

Then setup the `when:` clause with a third that only executes this play on OS versions that have `systemctl` (e.g. RHEL 7+, etc).  You run a play right before it that registers the full path of `systemctl` found on the system (maybe use `shell: which systemctl`).

Something like this:

     - name: manage services using systemctl
       tags:  manage services using systemctl

       systemd:
         name: {{servicesList}}
         state: {{actionTodo}}
       with_items:
         - "{{servicesList}}"
       when:
         - ansible_os_family == "RedHat" and ansible_lsb.major_release|int >= 7
         - actionTodo != ""
         - servicesList != ""
       ignore_errors: true
       register: p2

Correction to my previous email:

    You COULD run a play right before it that registers the full path of `systemctl` found on the system (maybe use `shell: which systemctl`), but that is not a stable method in some cases.  I suggest using `systemd:` with the OS version check if needed.
