IMHO, neither "shell" nor "loop_control" will make it. The runstring in
"shell" will be evaluated only once when the module starts. The
"loop_control" looks promising, but there is no option how to break a "loop"
in Ansible.
The best option would be to pass a variable, for example "number_of
retries" both to the script and to the module, and let the script make the
counting on its own. For example,
- name: process something, fail if not 5 files in tmpdir
command: "run.sh {{ number_of_retries }}"
...
retries: "{{ number_of)retries }}"
