Dear All,

Can anyone please let me know how to use a register variable in JSON.

Where JSON is passed as an argument to a command using command module.

Any help or assistance would be highly appreciated.

Thanks,  
Alok

Something like this should work:

[wani@linux tmp]$ cat a.yaml  
- hosts: localhost

&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;- command: 'echo {\"key\": \"value\"}'  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;register: my\_output

&nbsp;&nbsp;&nbsp;&nbsp;- debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: "{{ my\_output.stdout | from\_json }}"

On, run, it will show:

TASK [debug] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
task path: /tmp/a.yaml:7  
ok: [localhost] =\> {  
&nbsp;&nbsp;&nbsp;&nbsp;"changed": false,  
&nbsp;&nbsp;&nbsp;&nbsp;"msg": {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"key": "value"  
&nbsp;&nbsp;&nbsp;&nbsp;}  
}
