An Easy-To-Follow Guide On Learn How To Extract Rar File Using Tar Command

Extracting RAR files using the tar command might seem impossible at first glance, as tar is primarily designed for working with TAR archives, not RAR. However, there's a common misconception surrounding this. You cannot directly extract a RAR file using the tar command. tar and RAR are entirely different archive formats and require different tools for extraction.

This guide will clarify this misconception and provide you with the correct method for extracting RAR files on various operating systems.

Understanding the Difference: TAR vs. RAR

Before we delve into the solution, let's clarify the distinction between TAR and RAR archives:

  • TAR (Tape ARchive): This is a widely used Unix-based archiving utility. It primarily combines multiple files into a single archive file, but doesn't inherently compress the data. Compression is often added using tools like gzip (*.tar.gz or *.tgz) or bzip2 (*.tar.bz2). The tar command is used for both creating and extracting TAR archives.

  • RAR (Roshal Archive): A proprietary archive format known for its high compression ratios. It requires a dedicated RAR extraction utility. The tar command is not compatible with RAR archives.

The Correct Way to Extract RAR Files

Since tar won't work, you need a RAR extraction tool. Here's how to extract RAR files on different systems:

1. Using unrar (Linux and macOS)

On Linux and macOS systems, the most common and effective way to extract RAR files is using the unrar command-line utility. This often requires installation.

Installation (Linux):

The installation process varies depending on your Linux distribution. Here are some common examples:

  • Debian/Ubuntu: sudo apt-get update && sudo apt-get install unrar
  • Fedora/CentOS/RHEL: sudo yum install unrar
  • Arch Linux: sudo pacman -S unrar

Installation (macOS - using Homebrew):

If you have Homebrew installed, run: brew install unrar

Usage: Once installed, you can extract a RAR file (e.g., my_file.rar) using:

unrar x my_file.rar

This will extract the contents of my_file.rar to the current directory. You can specify an output directory using the -o option:

unrar x -oMyOutputDirectory my_file.rar

2. Using 7-Zip (Windows)

On Windows, 7-Zip is a popular and free file archiver that supports RAR extraction, along with many other formats.

Installation: Download the 7-Zip installer from the official website and follow the installation instructions.

Usage: Once installed, you can right-click on the RAR file, select "7-Zip," and choose "Extract Here" or "Extract to...".

3. Using GUI File Managers (All Operating Systems)

Many graphical file managers (like Finder on macOS, Nautilus on GNOME Linux, or File Explorer on Windows) have built-in support for RAR extraction. You might need to install additional plugins or extensions depending on your system configuration. Try right-clicking on the RAR file and look for an "Extract" option.

Troubleshooting Common Issues

  • unrar not found: This means the unrar utility isn't installed on your system. Follow the installation instructions above for your operating system.
  • Permission errors: You might need administrator/root privileges to extract some RAR files. Use sudo before the unrar command (on Linux/macOS).
  • Corrupted RAR file: If the extraction fails, the RAR file itself might be corrupted. Try downloading it again from the source.

Conclusion

While the tar command is a powerful tool for working with TAR archives, it is not suitable for RAR files. Remember to use the appropriate extraction utility (like unrar or 7-Zip) for your operating system to successfully extract your RAR archives. This guide has hopefully clarified the process and equipped you with the knowledge to handle RAR files efficiently.
