Dealing with compressed files in Linux, especially GZ files, can be confusing. In this post, I’ll walk you through easy methods to unzip GZ files using different tools and commands. Whether you like using the command line or a graphical interface, there’s a method for you. You’ll also pick up some best practices for efficient file management. By the end, you’ll handle GZ files with confidence and improve your Linux skills.
How to Create & Unzip GZ Files/TGZ Files in Linux
Archive types like RAR require an app to decompress on macOS, but you don’t need to do that for GZ. You’ll just need access to the Terminal (CLI), or GUI access, and access to the file itself. We’ll go into detail and show more examples with more options below.
Method 1: Using the gzip Command
- A .tar.gz file is an archive created using the tar utility and then compressed using gzip.
- To confirm the change, display all the files in the current directory.
- It is often used with a compression utility such as Gzip or Bzip2 to space disk space.
- Once you pick a location, navigate there once the process has completed and you should see a new folder with all the extracted files waiting for you.
- The tokens are used to replace the strings in the data and, because the tokens are smaller than the data they replaced, the file is compressed.
We can create an archive file that contains a directory tree and all of its files, but we need to bring another command into play. The tar program is used to create archives of many files, but it doesn’t have its own compression routines. But by using the appropriate options with tar, we can cause tar to push the archive file through gzip. That way we get a compressed archive file and a multi-file or multi-directory archive. Alternatively, you can use the gzip -d command by typing gzip -d filename.gz in the terminal to achieve the same result while preserving the original GZ file. For .tar.gz files, use the tar command by executing tar -xzf archive.tar.gz in the terminal to extract the contents while preserving the directory structure.
Interestingly, there is no difference between using level 9 compression and level 6 compression. You can only wring so much compression out of any given file and in this case, that limit was reached with level 6 compression. With bigger files, the difference between level 6 and level 9 would be more pronounced. The DEFLATE algorithm also incorporated ideas from two earlier compression methods, Huffman coding and LZ77 compression. The unique strings are allocated a unique ID token by virtue of their position in the tree. The tokens are used to replace the strings in the data and, because the tokens are smaller than the data they replaced, the file is compressed.
How to Uncompress a ‘.gz’ File in Linux With Gunzip Command
One of the things you’ll come across during everyday use of a great Linux distribution like Ubuntu is installing apps and opening certain files. While most apps can be found whats a crypto exchange a simplified guide in the Ubuntu Software Center or even as manual downloads, there might be a time when an app or a file you want will come as a tar.gz file type. The Linux man pages are a collection of documentation pages that describe the various commands and utilities that are offered on Linux systems.
GNU Gzip Manual
Moving ahead, now we will discuss some examples of the gunzip command to understand its usage. If you know in advance that you’re happy to have the file in the directory overwritten by the file from the archive, use the -f (force) option. That being the case, we would like to recommend you try out WinZip, the world’s best file archiver and unzipper. If you’d rather unzip a GZ file on your Windows using apps, there are lots of free alternatives.
In this guide, we’ll provide you with a step-by-step process on how to unzip a GZ file in Linux using both the command line and GUI tools. We’ll also cover other essential concepts like file compression, Gzip command Linux, and troubleshooting common errors. Tar and Gzip/Gunzip commands allow system administrators to create and unzip GZ and TGZ files. Gzip/Gunzip and Tar are installed by default on most Linux distributions, so all you need is SSH access and basic knowledge of the Linux command line interface. The “gunzip” command provides a “-l” flag which displays the information about the compressed file without necessitating its decompression.
The -l (list) option provides some information about an archive file. It shows you the compressed and uncompressed sizes of the file in the archive, the compression ratio, and the name of the file. There are many file compression utilities, but the one you’re guaranteed to find on every Linux distribution is gzip. If you only bitcoin has just halved again 2020 learn to use one compression tool, it should be gzip . Like ZIP, you can simply double-click on your GZ archive, and it should start extracting its content. You can do this from any Finder window on your Mac, and your extracted files will be available in a new folder in the same directory as the original GZ archive.
Gzip is an implementation of the DEFLATE algorithm which was invented—and patented—by Phil Katz of PKZIP fame. The DEFLATE algorithm improved on earlier compression algorithms which all operated on variations of a theme. The data to be compressed is scanned, and unique strings are identified and added to a binary tree. Since GZ files are compressed formats, after all, it goes without saying that extracting them requires a utility that can perform this task.
High compression and quick decompression are offered by the xz utility. Without using any external software, you can easily extract gz files in Linux using these commands. To ensure that you extract the correct file, it’s crucial to keep in mind to navigate to the appropriate directory before running any of these commands. This is an archive of files, almost similar to ZIP on Windows 11 and other operating systems. It combines both the TAR (which is known as tape) archive and the ZIP archive format into one, so the data is how to estimate the software development costs compressed and reduced in size. Naturally, you’ll need to extract the tar.gz file to install or open whatever is inside.
