-## Ad-Hoc Commands
+# Ad‑hoc Commands
+
+**Problem** – “I need to run a quick check or command on a host without writing a full playbook.”
+
+**Solution** – Use the `ansible` command with the `-m` (module) option.
+
+| Use‑case | Command | What it does |
+|----------|---------|--------------|
+| Ping a host | `ansible host1 -m ping` | Verifies connectivity. |
+| List services | `ansible host1 -m shell -a 'systemctl list-units --type=service'` | Executes a shell command. |
+| Gather facts | `ansible all -m setup` | Collects system information. |
+| Run playbook file only | `ansible-playbook site.yml` | Executes the full playbook. |
+
+**Example – Quick package check**
 
 ```bash
-ansible all -m ping
-ansible all -m command -a "uptime"
-ansible webserver -m apt -a "name=vim state=present"
+ansible web2 -m yum -a "name=nginx state=latest"
 ```
 
-Ansible is ideal for orchestrating infrastructure as code across cloud, on-premise, and hybrid environments.

+> **Tip** – Add `-vv` for verbose output to see command execution details.
