In this article, we will explore how to extract tar files to restricted folders in Ubuntu. This is a common problem faced by many users, especially when dealing with system directories like /opt.
To extract tar files to restricted folders in Ubuntu, you can use the Terminal and run the command sudo tar xf filename.tar.gz -C /opt. Another method is to use the Archive Manager as root by launching it with the command sudo -i file-roller 2>/dev/null &. If all else fails, you can extract the files to a different location and then move them to the restricted folder using the sudo mv command.
Understanding the Basics
Tar files, also known as tarballs, are a type of compressed file format used in Unix and Linux systems. They are often used to distribute software packages. Extracting these files can sometimes be a challenge, especially when you need to extract them to restricted folders.
In Ubuntu, certain folders are restricted to prevent unauthorized changes to important system files. The /opt folder is one such example. It’s used to store additional software and packages that are not part of the default Ubuntu installation.
Extracting Tar Files Using Terminal
The most straightforward way to extract tar files to restricted folders is by using the Terminal. Here’s how you can do it:
- Open the Terminal by pressing
Ctrl+Alt+T. - Navigate to the location of the tar.gz file using the
cdcommand. For example, if your tar file is in the Downloads folder, you would typecd Downloads. - Use the
sudocommand to extract the file to the/optfolder. For example:
sudo tar xf filename.tar.gz -C /optIn this command, sudo gives you superuser privileges, tar is the command to deal with tar files, xf is used to extract files, and -C specifies the directory to extract to. Replace filename.tar.gz with the actual name of your tar file.
Using Archive Manager as Root
Another method is to use the Archive Manager as root. Here’s how:
- Open the Terminal.
- Launch the Archive Manager program as root by typing:
sudo -i
file-roller 2>/dev/null &For Ubuntu MATE, replace file-roller with engrampa. This command opens the Archive Manager with root privileges, allowing you to extract files to any location.
- Navigate to the location of the tar.gz file in the Archive Manager and extract it to the desired location.
- After you’re done, exit the root shell by typing
exitin the Terminal.
Extracting to a Different Location
If you’re still having trouble, you can extract the files to a different location and then move them to the restricted folder. Here’s how:
- Extract the tar file to a folder in your home directory or the
/tmpfolder. - Use the
sudo mvcommand to move the extracted files to the/optfolder. For example:
sudo mv ~/yourfolder /optReplace yourfolder with the name of the folder containing the extracted files.

Always remember to exercise caution when dealing with system directories to maintain the stability and security of your system. And whenever possible, it’s recommended to install software using Ubuntu’s package manager or official repositories.
For more information about the tar command and its options, you can check out the official Ubuntu documentation.
Yes, you can extract tar files to any folder in Ubuntu. However, certain system folders like /opt may require superuser privileges to make changes.
Restricted folders in Ubuntu, such as /opt, are protected to prevent unauthorized changes to important system files. Using sudo gives you superuser privileges, allowing you to make changes to these restricted folders.
The -C option in the tar command is used to specify the directory to which the files should be extracted. For example, -C /opt will extract the files to the /opt folder.
Yes, you can use the Archive Manager as root to extract tar files to restricted folders. Launch the Archive Manager as root using the sudo -i command, and then navigate to the location of the tar.gz file to extract it.
If you’re unable to extract tar files directly to a restricted folder, you can extract them to a different location and then use the sudo mv command to move the extracted files to the restricted folder.
Yes, it’s important to exercise caution when dealing with system directories to maintain the stability and security of your system. Always double-check the commands you are using and ensure that you have a backup of important files before making any changes.
