+# 📘 **Using the `wc` Command in Linux/Unix**
+
+`wc` (word count) is a utility that counts lines, words, and bytes or characters in files. It’s useful for quickly getting file size details in text terms.
+
+---
+
+## ⚙️ Syntax
+
+```bash
+wc [option] file
+```
+
+---
+
+## 🔎 Basic Usage
+
+```bash
+wc file
+```
+
+**Example output:**
+
+```
+ 5  6 43 file1
+```
+
+This output means:
+
+| Number | Meaning             |
+| ------ | ------------------- |
+| `5`    | Number of **lines** |
+| `6`    | Number of **words** |
+| `43`   | Number of **bytes** |
+
+---
+
+## 📋 Common Options
+
+| Option | Description               | Example      |
+| ------ | ------------------------- | ------------ |
+| `-l`   | Count **lines** only      | `wc -l file` |
+| `-w`   | Count **words** only      | `wc -w file` |
+| `-c`   | Count **bytes** only      | `wc -c file` |
+| `-m`   | Count **characters** only | `wc -m file` |
+
+---
+
+## 📌 Notes
+
+* `bytes (-c)` counts raw bytes, which might differ from characters (`-m`) in multibyte encodings like UTF-8.
+* Without options, `wc` outputs lines, words, and bytes by default.
