In this guide, you will learn how to extract or unzip .tar.gz files in Linux. The tutorial also explains how to handle specific file extractions, preserve file ownership, and ensure security when working with untrusted archives. Gzip is a file compression tool in Linux that reduces file sizes, making them easier to store and transmit. It uses the DEFLATE algorithm to compress data without losing quality, commonly used for log files and web content. With the command prompt open, use the appropriate commands to change the current working directory (cd) to the location of the .tar.gz file you want to unzip. Alternatively, you can also specify a source and destination file path when using the tar utility.
tar: Unrecognized archive format
On Windows, the easiest way to handle .tar files is to install the LGPL open source 7-Zip utility. Its name implies it’s a zip utility, but it also works with tar archives, and even provides commands for the cmd command-line interface. This error usually occurs when a .tar has been saved as a .gz despite having never been compressed using the gzip utility. It may sound like a silly mistake, but it’s surprisingly common in situations where users directly rename files and their extensions (such as .tar and .gz) in the process. If you’re trying to extract a TAR file on Windows, particularly a .tgz or tar.gz file, there are several ways to do it easily. Although Windows doesn’t natively support extracting these files, there are plenty of TAR file extraction tools for Windows that can help you.

Now the file “four” is extracted to a new directory called “bar.” If “bar” already exists, then “four” is placed inside the existing directory. Most Linux systems come by default Tar tool to deal with the Archive files created using it. If you plan to distribute and store .tar.gz files on your website, Kinsta’s managed hosting services can help make the most of your space. Similar to the previous error, this error occurs when an archive was saved as a .tar despite not being a .tar archive. You can also use –wildcards to extract all files with a certain extension or name. Otherwise, keep reading to learn how to unzip .tar.gz files in Linux, macOS, and Windows.
To extract the tar.gz file, you’ll use the tar command followed by -xzf and the name of the file. The -xzf stands for extract (-x), gzip files (-z), and file (-f). This command extracts the contents of the archive into /path/to/destination/. This is particularly useful when organizing extracted files into dedicated directories. It’s often useful to list the contents of a .tar.gz file without having to unzip the entire archive.
The tar format only creates a container for files, but the files can be compressed with separate utilities. Common compressions applied to a .tar file are Gzip, bzip2, and xz. That’s why you rarely see just a .tar file and more commonly encounter .tar.gz or .tgz files. Just like the more familiar .zip files, .tar files compress large files into a single package, making it easier to store and send them through email, servers, and so on. As a result, it has become a common file extension for many open-source software packages and other resources.
Using third-party tools
In addition, they allow you to compress multiple files into a single archive, making it easier to manage large numbers of files. Unlike Windows’ convenient graphical user interface (GUI) for unzipping .zip files, you need to use the tar utility through the command line. However, there are also many third-party tools you can install for a more user-friendly experience.
Working with compressed files on Linux often involves using gzip due to its speed and effective compression ratio. Here’s how to decompress gzip files and address common issues. Tar.gz files, also known as “tarballs,” are a type of file format that is commonly used in Linux and other Unix-based operating systems. A tarball is essentially a compressed archive that contains one or more files or directories. These files are typically compressed using the gzip compression algorithm, resulting in a smaller file size than their uncompressed counterparts. While every tar.gz file is a .tar archive, not every .gz is a .tar file.
Extract a tarball to another directory
- It’s easy to get confused when navigating between .tar, .tar.gz, and .gz – not to mention zipping and unzipping them.
- People new to the tar format usually equate it to a .zip file, but a tar archive is notably not compressed.
- These tools and commands are your keys to enhancing Linux data management through effective compression.
- You have to select the TAR File & want to choose the operation.
- In other words, .zip files are a collection of compressed files, while .tar files are a compressed collection of files.
- On Linux, BSD, Illumos, and even Mac OS, the tar command is already installed for you.
If you want to keep the original file after compression, there are two options. The first is the -k option, and the other uses the -c option to output the compressed file to a different file, preserving the original. Thankfully, you don’t need to be a 1960s computer technician to use and extract .tar files – nor do modern .tar how to buy sell and trade cryptocurrencies files even have anything to do with old computers. However, if an archive was created with files stored in subdirectories, use the exact path shown inside the archive.
How does gzip differ from other compression tools?
Unzipping and extracting tar.gz files is not difficult on any mainstream operating system, whether using Linux, Windows, or macOS. We have already discussed the syntax a user needs to follow; however, if you face any problems, let us know using the comment section. Last, don’t forget that Windows users can use Winrar or 7-Zip’s GUI to extract the Tart.gz how to sell bitcoin in the uk files.
How to Unzip a GZ File (Single File Compression)
Any remotely modern version of tar should auto-detect that the archive is gzipped, and add “z” for you. This command extracts only FileA.txt from inside the subdir directory, leaving the rest of the archive untouched. By using these strategies, you can make data transfers more efficient, especially with large datasets or when planning backups.
For more options and real-world scenarios, explore the GNU official gzip documentation. If how to buy audius tar is installed, this command will output information about the version of tar that is installed on your system. I had a lot of fun, three years ago or so, running a bunch of tests with different compression methods, and it was very enlightening to see how various files took to compression. You’ll probably have to install the “other” tar (whatever that may be on your system) manually. If you have an existing tarball and want to add a new file into it, you don’t have to unarchive everything just to add a new file. If you’ve received a tarball from a friend or a software project, you can extract it in either your GUI desktop or in a shell.
- Here are a few frequently asked questions we commonly hear from users working with .tar.gz files.
- As you might imagine, using a different compression utility on a .tar file will result in a different double extension.
- Whether you’re optimizing disk space on a server or enhancing data transfer efficiency, compression can significantly boost your workflow.
- As we cover more in the next section, you can verify file names by listing contents with the tar -tf filename.tar.gz command.
- In addition, they allow you to compress multiple files into a single archive, making it easier to manage large numbers of files.
Therefore, when extracting from a .tar.gz archive that contains such a structure, you must specify the full internal path to the file, exactly as stored in the archive. A frequent error is “not in gzip format,” which occurs when the file isn’t actually a gzip file. Enhance your server’s performance by learning to run scripts at startup automatically in Linux, ensuring efficient execution of gzip commands as soon as your system boots. The Linux command line interface (CLI) is a powerful tool for interacting with your computer.
Gzip employs the DEFLATE algorithm, combining LZ77 compression and Huffman coding to replace recurring strings with shorter symbols. This method effectively reduces file size without losing data. For more advanced compression techniques, you might also explore how to open and extract .tar.bz2 files by example. Both commands will result in an uncompressed `filename.tar` archive. You can then proceed with extracting or modifying its contents by using `tar` as shown above. I use this option so that when I extract files from a tarbomb, they remain tidy and contained.
Using tar with gzip simplifies directory management and boosts data transfer effectiveness. Understanding these basics and troubleshooting tips will help you optimize Linux disk space and improve data management. Compressed files save disk space and bandwidth, making them ideal for archiving logs, system backups, and application distributions. As a Linux administrator, you often encounter tar.gz files when downloading software from repositories or managing system logs. Understanding how to properly extract, unpack, and decompress these files will streamline your workflow and automate routine tasks. You can create your own compressed .tar files using compression utilities such as gzip.
