Want to quickly check your Linux system logs? In this video, I’ll show you how to use **`dmesg`** and **`journalctl`** to troubleshoot hardware, boot issues, and system services.

### 🔹 `dmesg` examples:

```bash
dmesg | less
```

👉 Displays kernel ring buffer messages with scrolling. Great for viewing boot logs and hardware detection.

```bash
dmesg | grep usb
```

👉 Filters logs for **USB devices**. Perfect to check if your USB is detected.

```bash
dmesg -T
```

👉 Shows logs with **human-readable timestamps** instead of raw time.

### 🔹 `journalctl` examples:

```bash
journalctl -xe
```

👉 Displays the **most recent logs with details** (errors, warnings, crashes).

```bash
journalctl -u ssh
```

👉 Shows logs only for the **SSH service**. Useful for debugging login issues.

```bash
journalctl --since "1 hour ago"
```

👉 Filters logs from the **last hour**. Helps find recent issues quickly.
