+# 🔗 **Linux Links: Soft Link vs Hard Link**
+
+## 📝 **Types of Links**
+
+In Linux, there are **two types** of links:
+
+1. 🪶 **Soft Link** (Symbolic Link)
+2. 🪨 **Hard Link**
+
+---
+
+## ⚙️ **Commands**
+
+### 🪶 **Soft Link (Symbolic Link)**
+
+Acts like a **shortcut** pointing to the original file.
+
+```bash
+ln -s <base-file> <link-file>
+```
+
+💡 **Example:**
+
+```bash
+ln -s file.txt file_link.txt
+```
+
+---
+
+### 🪨 **Hard Link**
+
+Points directly to the file's **inode** (physical data on disk).
+
+```bash
+ln <base-file> <link-file>
+```
+
+💡 **Example:**
+
+```bash
+ln file.txt file_hard.txt
+```
+
+---
+
+## 📊 **Soft Link vs Hard Link**
+
+| 🏷️ Feature               | 🪶 Soft Link (Symbolic)           | 🪨 Hard Link                  |
+| ------------------------- | --------------------------------- | ----------------------------- |
+| 🔢 **Inode Number**       | Different from the original file  | Same as original file         |
+| 🗂 **Cross Filesystem**   | ✅ Yes                             | ❌ No                          |
+| ❌ **If Original Deleted** | Link breaks (becomes invalid)     | File still exists             |
+| 📦 **Storage**            | Stores path to original file      | Stores actual data reference  |
+| 🔄 **Update**             | Reflects changes in original file | Reflects changes (same inode) |
+
+---
+
+## 🧠 **Quick Notes**
+
+* **Soft Link** → Think *shortcut* 📎
+* **Hard Link** → Think *clone reference* 📀
+* If you delete the **base file**:
+
+  * 🪶 Soft Link → ❌ Broken link
+  * 🪨 Hard Link → ✅ Still works (data intact)
