You can make your shell command much more efficient. No need to use cat and
grep.
awk -F: '$1 ~ /^ora/ { print $1 }' /etc/passwd
This will find and print all usernames that begin "ora".
- shell: "awk -F: '$1 ~ /^ora/ { print $1 }' /etc/passwd"
register: userid
ignore_errors: true
Then you can look at userid.results.stdout_lines (as a list) to see the list of
usernames.
- debug: var=userid.results.stdout_lines

The variable *id* was registered in a loop. You need the attribute
*results*. (Take a look at *id*.)
Try
- debug:
msg: "{{ id.results|map(attribute='stdout')|list }}"
Notes:
* Use *getent* instead of reading /etc/passwd* on your own
https://docs.ansible.com/ansible/latest/collections/ansible/builtin/getent_module.html
* Use *command* instead of *shell*, *loop* instead of *with_items*,
and *userid.stdout_lines* instead of *userid.stdout.split('\n')*
- command: "id {{ item }}"
register: id
loop: "{{ userid.stdout_lines }}"
