Need help on formating stdout_lines output

[Suresh Karpurapu]

Hi All,

Would anyone please help me formatting mountchk.result. I am able to get the required output with item.stdout_lines[0],item.stdout_lines[1],item.stdout_lines[2] but host3 has 6 entries. So, please help me in filtering 

mountchk.results:

=================

host1:

     "stdout": "nfsflr01:/app01\n/app\n/etc/fstab",

     "stdout_lines": [

                "nfsflr01:/app01",

                "/app",

                "/etc/fstab"

host2: 

    "stdout": "nfsflr02:/app02\n/app02\n/etc/fstab",

    "stdout_lines": [

        "nfsflr02:/app02",

        "/app02",

        "/etc/fstab"

host3:

     "stdout": "nfsflr03:/app03\n/app03\n/etc/fstab\nnfsflr03:/app03\n/app03\n/etc/rc.willows",

     "stdout_lines": [

         "nfsflr03:/app03",

         "/app03",

         "/etc/fstab",

         "nfsflr03:/app03",

         "/app03",

         "/etc/rc.willows"

Required filtering:

==================

host1,nfsflr01:/app01,/app,/etc/fstab

host2,nfsflr02:/app02,/app02,/etc/fstab

host3,nfsflr03:/app03,/app03,/etc/fstab

host3,nfsflr03:/app03,/app03,/etc/rc.willows

You can use with_sequence or range in a for loop.

vars:
myvar:
- one
- two
- three
- four
- five
- six
tasks:
- debug: msg="{{ myvar[item | int] }},{{ myvar[item | int + 1] }},{{ myvar[item | int + 2] }}"
with_sequence: start=0 end={{ (myvar | length) - 1 }} stride=3

- debug:
msg: |
{% for i in range(0, myvar | length, 3) %}
{{ myvar[i] }},{{ myvar[i + 1] }},{{ myvar[i + 2] }}
{% endfor %}

Hi Sai Stian,

This syntax would be helpful but i may be using in wrong way as i am getting below errors. Please help on fixing the issue.

  - name: debug with with sequence
    debug:
      msg:"{{ volchk[item.stdout | int] }},{{ volchk[item.stdout | int + 1] }},{{ volchk[item.stdout | int + 2] }}"
    with_sequence: start=0 end={{ (volchk | length)-1 }} stride=3

error:

Can you paste the content of "volchk" list .. Also try using item.stdout_lines instead of item.stdout in your debug task.

[Suresh Karpurapu]

thanks Neha, Kai

I could fix the issue by using range with stdout.split(). Even, it is working with stdout_lines as well

Once again thanks to all for helping me on this request.

Suresh
