I would like to fail when the result.stdout has more than 1 lines / row
tasks:
- shell: command
register: result
- fail:
when: result.stdout has more than 1 lies / row
result.stdout looks like this
0:1:0
0:1:1
0:1:2
0:1:3
0:1:4
0:1:5
Along with stdout, the shell module also provides you a list stdout_lines which is:
The command standard output split in lines.
So you can achieve this using the Jinja length filter on this list:
- fail:
when: result.stdout_lines | length > 1
