Q:

Capture template output on the fly

I need to run a command on the target server that accepts data through stdin only.  The data I'm feeding it comes from a template file and contains sensitive data, so I'd rather not have it sitting in the filesystem even for a second. 
I'm trying to find a way to grab the output of a template task so I can pass it to the command.  Something like:
- name: generate data
  template:
    src: data.j2
    dest: [I'd rather not have any files written]
  register: myvar

- name: run command
  shell: "command < {{ myvar }}"

Is a better way to go about this that doesn't involve writing a temporary file, feeding it to the command and then erasing it? 

A:

Got answer from ansible guys:
some_var: "{{ lookup('template', 'tmpl.j2') }}"
