What is Tar Command in Linux?
The tar
command in Linux is a powerful tool used for creating, maintaining, extracting, and managing tar files—often referred to as tarballs. The name tar stands for Tape Archive, reflecting its original purpose for writing data to tape drives. This command is commonly used for file compression and archiving, allowing users to bundle a collection of files and directories into a single file. The resulting archive can be optionally compressed using additional utilities like gzip or bzip2.
Here are some basic usages of the tar
command:
- Creating an archive:
tar -cvf archive_name.tar directory_to_archive/
- Extracting an archive:
tar -xvf archive_name.tar
- Viewing the contents of an archive:
tar -tvf archive_name.tar
- Creating a compressed archive:
tar -czvf archive_name.tar.gz directory_to_archive/
(using gzip) - Extracting a compressed archive:
tar -xzvf archive_name.tar.gz
These options and utilities make tar
an essential command for file management and data transfer in Linux environments.
How to Use Tar Command in Linux?
To use the tar command in Linux, you start by creating an archive with tar -cvf archive_name.tar directory_name
, where -c
creates the archive, -v
shows the process, and -f
specifies the filename. To extract an archive, use tar -xvf archive_name.tar
, where -x
extracts the files.
For viewing contents, use tar -tvf archive_name.tar
, and to compress, add -z
for gzip (tar -czvf archive_name.tar.gz directory_name
) or -j
for bzip2 (tar -cjvf archive_name.tar.bz2 directory_name
).

Lists all files in the archive, helping you to identify specific file paths.
- To extract specific files, run the command:
tar -xzvf archive-name.tar.gz path/to/specific/file
Verify the files have been extracted to the current directory.
6. Updating Files in an Archive
Updating files in an archive allows you to add or replace files in an existing tar archive without recreating it from scratch.
- Launch your Terminal window and go to the directory.Type the following command and press enter:
tar -uvf archive.tar updatedfile.txt
This command updates updatedfile.txt in archive.tar if it is newer than the existing file.
7. Appending Files to an Existing Archive
Easily add new files to an existing tar archive. This feature is perfect for updating archive contents without creating a new archive from scratch.
- Access the command line and change to the directory where your archive is located.
- Add new files to the archive with:
tar -rvf archive-name.tar new-file
Appends new files to the existing archive without recreating it.
- Confirm the addition by listing the archive’s contents by running the command:
tar -tvf archive-name.tar
The output will be:
8. Excluding Files from an Archive
Excluding files or directories from an archive is useful when you want to archive a directory but omit certain files or subdirectories.
- Access your command window and navigate to the directory where the files are located.
- Run the following command to create the archive while excluding specific files:
tar --exclude=/home/guestuser/Downloads/file1.txt -cvf archive.tar /home/guestuser/Downloads
This command creates a tar archive while excluding the specified path.
9. Splitting an Archive into Multiple Files
Splitting a large archive into smaller parts is useful for easier storage, transfer, or handling when dealing with size limits on files.
- Open your Terminal and move to the desired directory. Type the following command and press Enter:
tar -cvf - /path/to/directory | split --bytes=500MB - archive.tar.part
This command creates a tar archive and splits it into multiple parts of 500MB each.
10. Preserving File Permissions and Ownership
Preserving file permissions and ownership is crucial when archiving system files or directories to ensure they retain their original properties when extracted.
- In your Terminal, run the following command to create the archive while preserving permissions and ownership:
tar -cvp --preserve-permissions --file=archive.tar /path/to/directory
This command creates a tar archive while preserving file permissions and ownership.
11. Comparing Archive Contents with the File System
Ensure data integrity by comparing the contents of a tar archive with the file system, identifying discrepancies and ensuring accurate backups or archives. Follow these steps to compare the archive content:

- To extract an archive to a specific directory, execute the command:
tar -xzvf archive-name.tar.gz -C /target/directory
Replace target/directory with the name of the directory in which you want to extract the files.
- Check the specified directory to ensure the files were extracted correctly.
16. Using Tar with Pipes for Efficient Workflows
Leverage piping with tar for efficient data transfer between commands, minimizing disk usage and streamlining data backup and restoration workflows. Here is the guide:
- Launch the command line.
- Directly compress and backup a directory by running the command:
tar cvf - /path/to/directory | gzip > archive-name.tar.gz
Compresses and backs up a directory in one step, using pipes to pass data between commands.
- For restoration, decompress and extract with the command:
gzip -dc archive-name.tar.gz | tar xvf -
The command will restore the backed-up compressed directory.
5 Best Practices for Using Tar in Linux
When working with tar in Linux, adopting best practices can significantly enhance your efficiency and data management. These practices ensure your archives are well-organized, secure, and easy to handle, whether you’re backing up data or sharing files. Here are five best practices to follow when using Tar in Linux:
- 📦 Use Descriptive Filenames: When creating tar archives, choose descriptive filenames that include the date of creation and content description. This practice helps in quickly identifying the purpose and age of an archive without needing to open it.
- 🔒 Secure Your Archives: Always encrypt sensitive data using tools like gpg before sharing or storing. Encryption adds a layer of security, protecting your data from unauthorized access during transit or in storage.
- 🔄 Verify Archives After Creation: Use the
tar -tvf
command to list the contents of an archive after creation. This step ensures all intended files and directories are included and there are no errors. - 🚀 Leverage Compression Efficiently: Choose the right compression method (gzip for speed, bzip2 for smaller size) based on your needs. Compression reduces file size, making storage and transfer more efficient but can increase processing time.
