+# File-5.46
+
+The `file` utility is a command-line tool that attempts to classify each given file according to its contents. It performs several tests to determine the file type, including filesystem tests, magic number tests, and language tests.
+
+## Features
+
+- **File Type Detection**: Identifies file types by examining their contents rather than just file extensions
+- **Magic Number Recognition**: Uses a database of "magic numbers" to recognize file formats
+- **Multiple Test Methods**: Employs filesystem tests, magic number tests, and language tests for accurate classification
+- **Extensible Database**: Uses an extensible magic database that can be customized
+- **Library Support**: Includes the libmagic library for use by other applications
+
+## Installed Programs
+
+- `file`: The main command-line utility for file type detection
+
+## Installed Libraries
+
+- `libmagic.so`: Contains routines for magic number recognition used by the file program and other applications
+
+## Common Usage
+
+```bash
+# Determine file type
+file document.pdf
+
+# Get MIME type
+file -i image.jpg
+
+# Show brief description
+file -b script.sh
+
+# Check multiple files
+file *.txt
+```
