Hi@akhtar,

When we need to perform a task multiple times. We generally use a loop to do this task. Here's an example using loops.

- name: Set kernal configuration
  lineinfile:
    dest: /etc/sysctl.conf
    regexp: "{{ item.regexp }}"
    line: "{{ item.line }}"
  loops:
    - { regexp: '^kernel.shmall', line: 'kernel.shmall = 2097152' }
    - { regexp: '^kernel.shmmax', line: 'kernel.shmmax = 134217728' }
    - { regexp: '^fs.file-max', line: 'fs.file-max = 65536' }
