compression What command do I need to unzip extract a tar.gz file?

The name of the GZ file you’re attempting to extract should be replaced by “filename.” The file’s integrity will be questioned by this command. The original file, a spreadsheet called “calc-sheet.ods” is 11 KB,  and the compressed file—also known as an archive file—is 9.3 KB. Note that the name of the archive file is the name of the original file with “.gz” appended to it.

What is a Tarball or Tarfile?

  1. GZ and TGZ files are considered file compression and archiving standards for Linux systems.
  2. Substituting the tokens for the original strings re-inflates the data back to its uncompressed state.
  3. You can unzip GZ files in Linux by adding the -d flag to the Gzip/Gunzip command.
  4. Tar and Gzip/Gunzip commands allow system administrators to create and unzip GZ and TGZ files.
  5. Furthermore, we have also discussed some of the common errors that you may encounter while unzipping gz files in Linux and provided troubleshooting tips to overcome these errors.

Additionally, we have introduced other useful gzip commands that you can use to compress or decompress other file types. The Burrows-Wheeler transform algorithm is used in the file compression format BZIP2. Text files or archives are frequently compressed practical capacity accountingtools with BZIP2 files.

Now You Know All About File Compression Tools in Linux

The z option of tar is simply a shortcut to do the decompression with gzip along with extracting the files. A GZ file is an archive compressed using the gzip compression technology. Like other compressed files, this archive type helps you combine your files and reduce the size of your files by compressing them. If you’ve seen the tar.gz or .tgz file types before, know that they are TAR files (tarballs) that were compressed with gzip. Tar is a utility used to merge several files into a single file, usually referred to as an archive, without compressing them.

The name of the gz file you want to decompress should be replaced with the name of filename. Gzip instructs it to decompress the file rather than compress it using the -d option. Compared to using the command line, using GUI tools can be more user-friendly and call fewer commands. However, using the command line might be more effective and faster if you need to extract a lot of files. Don’t mistake compression for encryption or any form of protection. Compressing a file doesn’t give it any security or enhanced privacy.

It’s a free archiving utility for both personal and commercial purposes, which offers support for the .gz file extension. As the file is the home/user directory we archived, we cannot easily extract it without having to restore the whole directory. Please note that you need to specify the full path to the file or directory you would like to extract.

You can unzip GZ files in Linux by adding the -d flag to the Gzip/Gunzip command. The GZ file will be removed by default after we uncompressed it unless we use the -k flag. Below we will unzip the GZ files we compressed in the same directory.

Most of the newer graphical distros like Ubuntu and Linux Mint come with built in tools to decompress files using a GUI. 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. GZ files are compressed files that typically contain multiple files and/or folders. To access the files inside, you’ll need to extract them similar to how you’d unzip a ZIP file.

If your target folder looks empty even after successfully running the command, that’s probably because you ran the it without admin privileges. Open the Command Prompt with administrative rights, and you should be fine. With a file as small as this, we didn’t see any significant difference in speed of execution, but there was a small difference in compression. The file is overwritten and you’re silently returned to the command line.

The second use of ls looks for all files beginning with “calc-” but it only finds the compressed file. That’s because, by default, gzip creates the archive file and deletes the original file. You can Untar Gzip-compressed Tar archives using the -x (extract) flag the Tar command provides. Again, you can specify what directory you would like to extract the archived files to, as Tar will place all the contents of the TGZ file to the current working directory by default.

The Simple Guide to Linux File Management: Counting Files in Directories Explained

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. Substituting the tokens for the original strings re-inflates the data back to its uncompressed state.

This archives the directory tree structure and all files within the directory tree. The gzip data compression tool was written in the early 1990s, and it’s still found in every Linux distribution. There are other compression tools available, but no matter which Linux computer you find yourself needing to work on, you’ll find gzip on it. So if you know how to use gzip, you’re good to go without the need to install anything. This is because most versions of tar allow both gnu and bsd style options (simplistically, gnu requires a hyphen, bsd doesn’t).

Unzip GZ files in Linux

To compress (or zip) a file, all you need to do is pass the name of the file to the gzip command. We’ll check the original size of the file, compress it, and then check the size of the compressed file. There are many file compression utilities, but the one you’re guaranteed to find on every Linux distribution is gzip.

But even with a fairly small file, there’s likely to be some reduction in size. Other not-so-common formats that you may come across on your computer are tarballs, or .TAR, and .XZ. Luckily, there are simple ways to extract files from these formats as well. Using the Terminal, you can extract all the files inside your GZ archive using a single command. Your files will be placed in a new folder in the same directory as the original GZ file.
