Ansible: How to run the for command through playbook

[nishant bawane]

Below is the playbook using "for command".

Playbook:

    - name: "Fetch the ip of all the servers from hosts.new file"
      shell: for i in `awk '{print $1}' hosts.new`
               do echo "$i"
               done
      args:
        chdir: "/home/dp794d/"
      failed_when: "output.rc > 1"
      register: output
   - debug: msg="{{ output.stdout }}"

Actual output :

PLAY [myserver] ****************************************************************

TASK [setup] *******************************************************************
ok: [zlp12037]

TASK [Fetch the ip of all the servers from hosts.new file] *********************
changed: [zlp12037]

TASK [set_fact] ****************************************************************
ok: [zlp12037]

TASK [debug] *******************************************************************
ok: [zlp12037] => {
    "output.stdout": ""
Expected output :

12.82.240.174
12.82.240.166
12.82.224.62
12.82.224.70

I'm baffled that you didn't get an error message since your for loop is
not valid syntax.

Try:

shell: for i in `awk '{print $1}' hosts.new`;
do echo "$i";
done

Or on one line

shell: for i in `awk '{print $1}' hosts.new`; do echo "$i"; done
