implement checks on every iteration using with_items

[Som Das]

Hi All,

I have the following code: 

- name: execute all commands in the file

  cisco.asa.aa_command:

       commands:

        - "{{ item }}"

  with_lines: cat ./role1/files/commands.txt

  register: output

Now I want to implement a check on every iteration, to check if a command is failed or not
