Ansible adhoc commands

Ansible adhoc commands are useful to perform the tasks in a single time. Mostly adhoc commands are using to check the log information, service status and gather information of cpu, memory etc.,

We will see some frequent using modules with examples.

1. user
2. file
3. copy
4. service

1. How to create a user

[ansible@rameshmsr11c ~]$ ansible all -b -m user -a "name=ramesh"
rameshmsr13c | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "append": false, 
    "changed": false, 
    "comment": "", 
    "group": 1008, 
    "home": "/home/ramesh", 
    "move_home": false, 
    "name": "ramesh", 
    "shell": "/bin/bash", 
    "state": "present", 
    "uid": 1007
}
rameshmsr12c | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "append": false, 
    "changed": false,

[ansible@rameshmsr11c ~]$ 

2. How to create a directory

[ansible@rameshmsr11c ~]$ ansible all -b -m file -a "path=/home/ramesh/test state=directory owner=ramesh group=ramesh"

    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": true, 
    "gid": 1008, 
    "group": "ramesh", 
    "mode": "0755", 
    "owner": "ramesh",
