18 Useful Tar Command Examples for Every Linux Sysadmin

The main purpose of this guide is to provide various tar command examples that might be helpful for you to understand and become an expert in tar archive manipulation.

1. Creating a Tar Archive File

The below example of the tar command will create a tar archive file tecmint-17-11-2023.tar for a directory /home/tecmint in the current working directory.

See the example of the tar command in action.

tar -cvf tecmint-17-11-2023.tar /home/tecmint/

Let’s discuss each option used in the above tar command.

• c – Creates a new .tar archive file.
• v – Verbosely show the .tar file progress.
• f – File name type of the archive file.

2. Creating a Tar Archive with Compression

To create a compressed archive file, we use the option 'z' (compress the archive using gzip). For example, the command below will generate a compressed file named 'MyImages-17-11-2023.tar.gz' for the directory ‘/home/MyImages‘. (Note: 'tar.gz' and 'tgz' are interchangeable terms).

tar cvzf MyImages-17-11-2023.tar.gz /home/tecmint/MyImages
OR
tar cvzf MyImages-17-11-2023.tgz /home/tecmint/MyImages

3. Creating a tar.bz2 File in Linux

The bz2 feature compresses and creates an archive file that is smaller in size compared to gzip. However, the bz2 compression method requires more time for both compression and decompression, whereas gzip is faster in both processes.

To create a highly compressed new tar archive named Phpfiles-org.tar.bz2 by bundling all files and subdirectories within the /home/php directory, use the -j option, which instructs tar to utilize the bzip2 compression algorithm, resulting in a smaller file size for efficient storage and transfer.

Note: tar.bz2 and tbz are similar terms, both referring to tb2.

tar cvfj Phpfiles-org.tar.bz2 /home/tecmint/php
OR
tar cvfj Phpfiles-org.tar.tbz /home/tecmint/php
OR 
tar cvfj Phpfiles-org.tar.tb2 /home/tecmint/php

4. Extracting a Tar Archive

To untar or extract a tar file, simply execute the following command using the 'x' option (extract). For instance, the command below will untar the file named ‘tecmint-17-11-2023.tar‘ in the present working directory.

tar -xvf tecmint-17-11-2023.tar

If you want to untar in a different directory then use option -C (specified directory).

tar -xvf tecmint-17-11-2023.tar -C /home/tecmint/

5. Extracting a Compressed tar.gz Archive

To extract the contents of a compressed tar archive file named “MyImages-17-11-2023.tar.gz“, use the following command.

tar -xvf MyImages-17-11-2023.tar.gz

If you would like to extract in a different directory, just use the option -C, which will extract the files into the specified directory as shown.

tar -xvf MyImages-17-11-2023.tar.gz -C /home/tecmint/

6. Extracting a tar.bz2 Archive

To uncompress the highly compressed tar.bz2 file, simply use the following command, which will untar all the files from the archive file.

tar -xvf Phpfiles-org.tar.bz2

7. Listing Contents of tar Archive

To list or view the contents of the tar archive file, simply run the following command with the -t option (list content), which will display a detailed list of files and directories contained within the ‘tecmint-17-11-2023.tar‘ archive.

tar -tvf tecmint-17-11-2023.tar

8. Viewing Contents of tar.gz Archive

The following command will display a detailed list of files and directories contained within the “MyImages-17-11-2023.tar.gz” archive.

tar -tvf MyImages-17-11-2023.tar.gz

9. Printing Contents of tar.bz2 Archive

The following command provides an overview of the contents within the “Phpfiles-org.tar.bz2” archive without extracting the files.

tar -tvf Phpfiles-org.tar.bz2

10. Extracting a Single File from an Archive

To extract a single file named wp-cron.php from the archive Phpfiles-org.tar.bz2, use the following command. Make sure to provide the correct path to the file you wish to extract.

tar -xvf Phpfiles-org.tar.bz2 home/tecmint/php/wp-cron.php

11. Extracting Multiple Files from an Archive

To extract or untar multiple files from tar, tar.gz, and tar.bz2 archive files, use the following command, which will extract files from the specified archive files.

tar -xvf tecmint-17-11-2023.tar "file1" "file2" 
tar -zxvf MyImages-17-11-2023.tar.gz "file1" "file2" 
tar -jxvf Phpfiles-org.tar.bz2 "file1" "file2"

12. Extract a Group of Files Using Wildcard in Linux

To extract a group of files we use wildcard-based extracting. For example, to extract a group of all files whose pattern begins with .php from a tar, tar.gz, and tar.bz2 archive files, use:

tar -xvf Phpfiles-org.tar --wildcards '*.php'
tar -zxvf Phpfiles-org.tar.gz --wildcards '*.php'
tar -jxvf Phpfiles-org.tar.bz2 --wildcards '*.php'

13. Appending Files to an Existing Archive

To add files or directories to the existing tar, tar.gz, and tar.bz2 archive files, use the option -r, which will add the files to an existing archive file.

tar -rvf tecmint-14-09-12.tar xyz.txt
tar -rvf MyImages-14-09-12.tar.gz xyz.txt
tar -rvf Phpfiles-org.tar.bz2 xyz.txt

14. Verifying a Tar Archive File

The following command will display a detailed list of files and directories contained within the specified archive file, allowing you to visually verify the archive’s contents. If the archive is corrupted or incomplete, this verification process may reveal errors during the listing.

tar -tvf Phpfiles-org.tar.bz2

15. Checking Tar Archive File Size

To check the size of any tar, tar.gz, and tar.bz2 archive file, use the following command, which will display the size of the archive file in Kilobytes (KB).

tar -czf - tecmint-14-09-12.tar xyz.txt | wc -c
tar -czf - MyImages-14-09-12.tar.gz xyz.txt | wc -c
tar -czf - Phpfiles-org.tar.bz2 xyz.txt | wc -c

16. Excluding Files When Creating a Tar Archive

To exclude certain files and directories while creating a tar archive file, you can use the following command with the --exclude an option that will exclude files and directories when creating the tar archive file as shown.

tar --exclude="file1.txt" -zcvf backup.tar.gz /home/tecmint
tar --exclude="/home/tecmint/uploads" -zcvf backup.tar.gz /home/tecmint

In the above command, we excluded file ‘file1.txt‘ and ‘uploads‘ directory from the /home/tecmint folder.

To exclude files with specific file extensions (.txt) when creating a tar archive file, use:

tar --exclude="*.txt" -zcvf backup.tar.gz /home/tecmint

17. Removing Files From a Tar Archive

The following tar command will delete a file or directory from an already created tar file using the --delete option, as shown.

tar --delete -f backup.tar.gz file1.txt
tar --delete -f backup.tar.gz '/home/tecmint/uploads'

18. Extracing File Extension From a Tar Archive

The following tar command will only extract files with the specific extension .png from the tar archive file using the --wildcards option as shown.

tar -xvf backup.tar.gz --wildcards '*.png'

19. Tar Command Usage and Options

Understanding the following various options and usage patterns of the ‘tar‘ command is essential for efficient file archiving, compression, and extraction.

• -c – create an archive file.
• -x – extract an archive file.
• -v – show the progress of the archive file.
• -f – filename of the archive file.
• -t – viewing the content of the archive file.
