How to Unzip GZ File in Linux in 3 Easy Ways
To unzip GZ files in Linux, you can use the command line or a graphical user interface (GUI). Additionally, you can use flags with the “gunzip” command for advanced options. Here is the step-by-step guide for each method:
1. Use the Linux Command Line
You can use the command line in the Terminal app to unzip GZ files in Linux. Follow these steps to easily extract GZ files using the command line:
- Launch the Terminal app on your Linux system and navigate to the directory where the GZ file is located using the cd command.
- Run the
gunzipcommand followed by the name of the GZ file you want to extract. For example:
- If the extraction is successful, you should see a new file with the same name as the GZ file but without the .gz extension.
2. Use a Graphical User Interface (GUI)
If you prefer a more user-friendly approach, you can use a GUI tool to extract GZ files in Linux. Here’s how to extract GZ files using the default file manager in Ubuntu:
- Navigate to the directory where the GZ file is located using the file manager.
- Right-click on the GZ file and select Extract Here or Extract to from the context menu.
- When the extraction is complete, a newly created folder with the identical name as the GZ file should appear.
3. Use the Gunzip Command with Flags
To use the
gunzip command with flags, you can apply various options to modify its behavior. Here are some examples of how to use the
gunzip command to manage other operations for the GZ files.
- Use the
-coption to write the decompressed output to standard output to decompress a file and specify the name of the output file.
gunzip -c file.gz > outputfile
- Another way to keep the original compressed file is to use the
-koption with the
gunzipcommand. This flag preserves the original compressed file after decompression.
gunzip -k file.gz
- To force the decompression of a GZ file and overwrite the output file if it already exists, you can use the
gunzip -f file.gz
- To display information about a GZ file without decompressing it, you should use the
gunzip -l file.gz

3 Commonly Used Commands to Manage GZ Files in Linux
In addition to the commands mentioned earlier in the article, several other useful commands can enhance your ability to work with GZ files in Linux. Here are some of them:
zgrep command is used to search for patterns in GZ files using regular expressions. It is similar to the
grep command, but works with compressed files. Here’s how you can use this command in the Terminal window:
zgrep "searchterm" filename.gz
The command will search for the specified “searchterm” within the given compressed file (filename.gz) and display any lines containing the search term in the standard output. This is helpful when you need to search for specific information within large, compressed files without having to manually decompress them first.
zmore lets you view the contents of GZ files one screen at a time. It combines the functionality of
more (a text-paging tool) and
gzip (a file compression tool). Here’s an example of how to use more with the GZ files in Linux command prompt:
This command will decompress the specified file (filename.gz) on-the-fly and display its contents one screen at a time in the terminal. You can navigate through the content using various keyboard commands. For example, pressing Enter will display the next line, while the Space key presents the subsequent screen or page. To backtrack, simply press b to return to the previous screen, and when finished, hit q to exit
zmore mode and revert to the Linux command prompt.
zless command is similar to
zmore, but allows you to freely scroll up and down through the contents of the file using the arrow keys. This makes
zless a more versatile tool for examining large compressed files. To use
zless, simply type the following in the Terminal window:
When this command is executed in the terminal, the specified file is decompressed on-the-fly, and its contents are displayed for easy scrolling using the arrow keys. In addition to scrolling, you can employ other commands, such as press q to exit
zless mode and return to the command prompt in your Terminal window.
5 Common Errors When Unzipping GZ Files in Linux
Sometimes, GZ extraction may fail or encounter issues. Here are some common errors and issues that you may encounter when unzipping GZ files in Linux and how to resolve them:
- 💿 “Disk space full” error: When encountering a “disk space full” error while trying to unzip GZ files, it’s necessary to free up space on the disk or move the GZ file to another location with sufficient space. To check the available disk space, you can use the command df -h, which provides an overview of the disk usage and available space on all mounted file systems. To remove unnecessary files or directories and free up space, you can utilize commands like
rmto remove files or
rmdirto remove empty directories.
