# Understanding the Differences Between systemctl and service Commands in Linux

Managing services is a critical aspect of Linux system administration. If you're a DevOps enthusiast or a Linux user, you've likely encountered two commonly used commands for this purpose: `systemctl` and `service`. At first glance, they may seem interchangeable, but they belong to different generations of service management systems. In this article, we'll dive into their differences and help you decide which one to use.

## **What Are** `systemctl` and `service`?

* `systemctl`:
    
    * A tool used to interact with the `systemd` init system, which is now the standard in most modern Linux distributions.
        
    * Allows detailed control over services and other `systemd` components such as timers, targets, and slices.
        
* `service`:
    
    * A command from older init systems like SysVinit or Upstart.
        
    * Still available in modern systems as a compatibility wrapper for `systemctl`.

## **Key Differences Between** `systemctl` and `service`

| **Aspect** | `systemctl` | `service` |
| --- | --- | --- |
| **Usage** | Works directly with `systemd`. | Compatible with older init systems. |
| **Syntax** | `systemctl <action> <unit_name>` | `service <service_name> <action>` |
| **Features** | Provides detailed logs, advanced controls, and works with systemd units. | Basic functionality, simpler output. |
| **Example: Status** | `systemctl status docker` | `service docker status` |
| **Modern Relevance** | Preferred for modern Linux systems. | Maintained for compatibility. |

## **Examples of Usage**

### **1\. Checking Docker Status**

* **Using** `systemctl`:
    
    ```bash
    systemctl status docker
    ```
    
    **Output**:
    
    * Displays detailed service status, including logs, active state, and process details.
        
* **Using** `service`:
    
    ```bash
    service docker status
    ```
    
    **Output**:
    
    * A simpler, more concise service status.
        

### **2\. Starting Docker**

* **Using** `systemctl`:
    
    ```bash
    systemctl start docker
    ```
    
* **Using** `service`:
    
    ```bash
    service docker start
    ```

## **Feature Comparison**

### **Advantages of** `systemctl`

* **Comprehensive Logs**: Get detailed logs using `journalctl`.
    
* **Advanced Service Management**: Enable, disable, mask, or unmask services effortlessly.
    
* **Support for Modern Use Cases**: Works with systemd-specific components like targets and timers.
    

### **Advantages of** `service`

* **Simplicity**: Provides straightforward service management commands.
    
* **Backward Compatibility**: Useful for systems that still use older init systems.

## **When to Use Which?**

| **Scenario** | **Preferred Command** |
| --- | --- |
| Working on a modern system with `systemd` | `systemctl` |
| Maintaining compatibility with older systems | `service` |

To check if your system uses `systemd`, run:

```bash
ps -p 1
```

If the output shows `systemd`, then `systemctl` is your go-to command.

## **Final Thoughts**

Both `systemctl` and `service` have their place in Linux system administration, but the choice depends on your system's init system and your requirements. For modern systems, `systemctl` is more powerful and feature-rich, while `service` remains a useful tool for simpler tasks and backward compatibility.

Whether you're managing Docker or other services, understanding these commands will help you take full control of your Linux system.
