tar Command in Linux With Examples

November 9, 2021


The GNU tar (short for Tape ARchiver) command is the most widely used archiving utility in Linux systems. Available directly in the terminal, the tar command helps create, extract, and list archive contents.

The utility is simple and has many helpful options for compressing files, managing backups, or extracting a raw installation.

This tutorial shows how to use the tar command through examples and the available options.

Linux tar Command With Examples


  • A system running Linux.
  • Access to the command line/terminal.
  • A file or files for testing the command.

Tar Command Syntax

The tar command general syntax is:

tar <operation mode> <option(s)> <archive> <file(s) or location(s)>
  • Operation mode indicates which operation executes on the files (creation, extraction, etc.). The command allows and requires only one operation.
  • Options modify the operation mode and are not necessary. There is no limit on the number of options.
  • The archive is the file name and extension.
  • The file name(s) is a space-separated list for extraction or compression or wildcard matched name.

There are three possible syntax styles to use the operations and options:

1. Traditional style, clustered together without any dashes.

For example:

tar cfv <archive> <file(s) or location(s)>

2. UNIX short option style, using a single dash and clustered options:

tar -cfv <archive> <file(s) or location(s)>

Alternatively, a dash before each option:

tar -c -f -v <archive> <file(s) or location(s)>

3. GNU long-option style with a double-dash and a descriptive option name:

tar --create --file <archive> --verbose <file(s) or location(s)>

All three styles can be used in a single tar command.

Tar Command Options

The following table outlines the commonly used tar operations and options.

Follow the examples in the next section to learn how to work with tar.

Tar Command Examples

The examples below have the following requirements:

1. Create a directory named tar_examples and navigate to the directory:

mkdir tar_examples && cd tar_examples

2. Make another directory called files in tar_examples and enter that directory:

mkdir files && cd files

3. Create files to populate the files directory:

touch file{0..100}.txt

To return to the parent directory, use:

cd ..
folder structure for examples

All the examples below work from the tar_examples directory.

1. Create an Archive

The syntax for creating an archive depends on the archive type. To make an archive, use tar with the -c or --create operation.

Create a tar Archive

To make a tar archive (also called a tarball), use:

tar cf <archive name>.tar <file(s) or location(s)>

For example, archive the files directory:

tar cf files.tar files

The output lists each file added to the archive. Display the directory contents to see the created file.tar archive:

tar cf files.tar files

The output lists each file added to the archive. Display the directory contents to see the created file.tar archive:

ls -l
tar cf terminal output

Create a tar.gz Compressed Archive

Add the -z option to create a compressed GNUzip (gzip) file:

tar czf <archive name>.tar.gz <file(s) or location(s)>

Note: Combine tar with find and xargs to find and archive files.

For example:

tar czf files.tar.gz files
tar czf terminal output

The file size is smaller than a regular tarball file and the original directory.

Create tar.bz2 Compressed Archive

The bzip2 is a file compression program and an alternative to gzip.

To create a tar.bz2 file, add the -j tag:

tar cjf <archive name>.tar.bz2 <file(s) or location(s)>

For example:

tar cjf files.tar.bz2 files
tar cjf terminal output

The bzip2 has a greater compression rate and takes longer than gzip.

Create tar.xz Archive

Use the -J tag to compress archives in the tar.xz format:

tar cJf <archive name>.tar.xz <file(s) or location(s)>

For example:

tar cJf files.tar.xz files
tar cJf tar.xz terminal output

The xz compression takes the longest when compared to both gzip and bz2. However, with larger files, xz has the highest compression rates.

2. Remove Files After Creation

To remove the files from disk after archiving, use the --remove-files option at the end:

tar cf <archive> <file(s) or location(s)> --remove-files

For example, create a tar archive with the files directory and remove it from the disk in one command:

tar cf files.tar files --remove-files
tar cf --remove-files

Check the directory contents to confirm the operation works correctly.

3. Extract from Archive

Extracting from an archive or compressed archive uses the -x or --extract operation with tar. The additional options depend on the file type and where tar should extract the components.

Extract From tar Archive

The general syntax for extracting from a tar archive is:

tar xf <archive name>.tar

By default, tar extracts all the components to the current directory. To indicate where to extract the components, add the -C option and specify the path:

tar xfC <archive name>.tar <path>

For example, to create a directory named extracted_tar and extract the files from files.tar, run:

mkdir extracted_tar && tar xfC files.tar extracted_tar
folder structure after tar xfC

The command doesn't output a confirmation message. Check the directory contents to confirm the components extracted successfully.

Extract From tar.gz Archive

Use the -z option to extract a tar.gz file:

tar xzf <archive name>.tar.gz

The command extracts the contents in the current directory. Add the -C option to specify the location:

tar xzfC <archive name>.tar.gz <location>

For example, create a new directory named extracted_gz and extract the files.tar.gz contents:

mkdir extracted_gz && tar xzfC files.tar.gz extracted_gz
folder structure after tar xzfC

The tar.gz compressed archives take the least time to extract when compared to other compression formats.

Extract From tar.bz2 Archive

To extract files from a tar.bz2 compressed archive into the current directory, use:

tar xjf <archive name>.tar.bz2

Extract tar.bz2 archives into a specific directory with:

tar xjfC <archive name>tar.bz2 <location>

For example, create a directory and extract the contents from files.tar.bz2:

mkdir extracted_bz2 && tar xjfC files.tar.bz2 extracted_bz2
folder structure after tar xjfC

Extract From tar.xz Archive

Add the -J option to extract from tar.xz compressed archives. The syntax to extract in the current directory is:

tar xJf <archive name>.tar.xz

To extract the contents to a specific directory, use the -C option and add the path:

tar xJfC <archive name>.tar.xz <location>

As an example, create a directory and extract the files.tar.xz contents:

mkdir extracted_xz && tar xJfC files.tar.xz extracted_xz
folder structure after tar xJfC tar.xz

The xz compression format is the middle ground between gz and bz2 when it comes to extraction time.

4. Overwrite Control

Tar overwrite controls handle situations where file names in the archive overlap with files in the working directory.

The three possible overwrite actions are:

1. Overwrite files in the working directory:

tar xf <archive> <Optional file(s) or location(s)> --overwrite

2. Don't overwrite files in the working directory:

tar xf <archive> <Optional file(s) or location(s)> --keep-old-files
tar xf --keep-old-files terminal output

If the files already exist, tar doesn't perform the extraction.

3. Extract files only if they are newer than the existing files:

tar xf <archive> <Optional file(s) or location(s)> --keep-newer-files
tar xf --keep-newer-files terminal output

If the files in the working directory are newer or the same age, tar does not extract the files.

5. List Archive Contents

Use the following command to list an archive's contents:

tar tf <archive>

The option works for any file extension containing tar.

For example, list the files and directories in the files.tar archive:

tar tf files.tar.gz
tar tf terminal output

The output lists all contents stored in the archive.

6. Find a File in an Archive

There are two ways to locate specific content using tar:

1. The -t option to list files in an archive is handy for locating specific files. Add the file name (or names) after the command:

tar tf <archive> <file(s)>

For example, to locate file50.txt in the files.tar.gz archive, run:

tar tf files.tar.gz file/file50.txt
find specific file tar tf

The option requires knowing the possible path to the file.

2. Use the tar together with the grep command to filter the output:

tar tf <archive> | grep <file(s)>

For example:

tar tf files.tar.gz | grep file50.txt
find specific file tar tf and grep

The option doesn't require knowing the possible path to the file.

7. Find Multiple Files in an Archive

Use the --wildcards option to match multiple file instances. For example:

tar tf files.tar.gz --wildcards file/files5*.txt
tar wildcard matching

Apply wildcard matching when files have a similar name, or for filtering a certain file type.

8. Exclude Files when Creating Archive

To exclude certain files from the archive during creation, add the following option:

tar cf <archive> --exclude='<pattern>' <files(s) or location(s)>

For example, create an archive from the files directory and exclude all .txt files:

tar cf files.tar --exclude='*.txt' files

List the archive contents:

tar tf files.tar
tar cf --exclude terminal output

The output shows no .txt files, only the files directory in the archive.

9. Extract Single File from Archive

Avoid extracting the whole archive if you need one or several files.

To get a single file from an archive:

1. List the contents and check if the file exists:

tar tf files.tar | grep file100.txt

The output prints the path to the file needed for the next step.

2. Extract the specific file with:

tar xf files.tar files/file100.txt
extract specific file from tar example

The command creates the directory files with only the indicated file. Follow the same steps to extract a single file from compressed archives by adding the appropriate tag. For example, use the -z option to pull from a tar.gz file.

10. Verbose Option

The verbose option displays additional information after running a tar command. Add -v or --verbose to any operation to see the result.

For example, create a tar.gz file and add -v:

tar czfv files.tar.gz files
tar czfv terminal output

The output shows each file as it is added to the archive.

Some tar commands show additional information when you add the -v tag twice. For example, try to add files to an archive with -vv:

tar czfvv files.tar.gz files
tar czfvv terminal output

The output prints a long listing format and looks similar to running the ls -l command.

11. Delete from Archive

To delete from the archive, locate the file you want to remove, for example:

tar tf files.tar | grep file100.txt

Then, remove the file using the --delete tag:

tar --delete -f files.tar files/file100.txt
tar --delete terminal output

The delete option does not work on compressed file formats.

12. Append Files to Archive

Append files to an existing archive using the -r tag. The syntax is:

tar rf <archive name>.tar <file(s) or location(s)>

For example, append the compressed files.tar.gz file to the files.tar archive:

tar rf files.tar files.tar.gz
tar rf terminal output

Already compressed archives cannot be updated, so the syntax only works for tarball files.

13. Combine Archives

Use the --concatenate or -A option to combine multiple archives. The basic syntax is:

tar Af <archive to extend> <archive to extend with>

As an example, copy the existing files.tar file using the cp command:

cp files.tar files_copy.tar

Next, concatenate the two archives:

tar Af files.tar files_copy.tar
tar Af terminal output

To confirm the concatenation worked, check the file size.

14. Difference Between Archive and Files

To check the difference between an archive and files on disk, use the -d tag:

tar df <archive name>

The command searches for the same contents and compares them to what is in the archive. The option only checks for existing files and ignores any newly added files.

The steps below show how to use the -d, --diff, or --compare tag with tar:

1. Create a tar archive:

tar cf files.tar files

2. Compare the archive with the existing directory:

tar df files.tar
tar df no difference

The output does not display anything, meaning there is no difference between the existing files.

3. Add text to an existing file in the files directory:

echo 'Hello' >> files/file0.txt

4. Compare the archive to the existing directory again:

tar df files.tar
tar df differences

This time, the output shows differences in the modification time and the size for a specific file. Comparing provides insight into any changes made on the system after creating the archive.

15. Update Files in Archive

Update the existing files in the archive with a newer version from disk with the -u option:

tar uf <archive> <file(s) or location(s)>

For example, update the files.tar archive with a changed text file:

tar uf files.tar files

Check the tar contents for the changed file:

tar tfv files.tar | grep files0.txt
tar uf terminal output

The command updates the archive with changed files without any overwrites.

16. Modified Time

Tar offers various options to modify the file's timestamp. Set a custom date when creating an archive by adding the --mtime option and providing a date:

tar cf <archive> <file(s) or location(s)> --mtime=YYYY-MM-DD

For example, create an archive and set the date to January 1st, 1999:

tar cf files.tar files --mtime=1999-01-01
tar cf --mtime terminal output

Alternatively, extract the files with the current date and time:

tar xf files.tar -m
tar xf -m terminal output

A useful feature when working with time is filtering files modified after a specific date. For example, to extract files created after a date, use the --newer-mtime option and add the date:

tar xf <archive> --newer-mtime=YYYY-MM-DD

17. Permissions

There are two possible ways to control file permissions with tar when extracting an archive:

1. Preserve original permissions:

tar xf <archive name> --preserve-permissions

The permissions are as stated in the file before archive creation.

2. Modify the permissions to the default umask value:

tar xf <archive name> --no-same-permissions

The files take on the default Linux permissions.

18. File Ownership

Tar allows file ownership configuration. For example, to set the file owner when creating an archive, add the --owner and --group options and provide values for each:

tar cf <archive> <file(s) or location(s)> --owner=<value> --group=<value>

The owner value represents the UID (User ID) while the group value is the GID (Group ID). To find these values for a user, run:

id <username>

For example, create an archive and set the ownership to root:

tar cf files.tar files --owner=0 --group=0
tar cf --owner --group terminal output

Tar allows preserving the ownership when extracting from an archive. To do so, add the --same-owner option at the end:

tar xf <archive> --same-owner

19. Write to External Program

The --to-command option instructs tar to send each extracted file to the standard output for an external program. The basic syntax is:

tar xf <archive> --to-command='<command>'

For example, extract the files.tar contents and pipe the file names as directories:

tar xf files.tar --to-command='mkdir $TAR_FILENAME'
tar xf --to-command terminal output

The command creates directories named after each extracted file. For more information and the available Linux environment variables, visit the manual page.

20. Create Daily Backups

To automate daily backups, create a bash script and add the following lines:

tar czf backup-$(date +%Y%m%d).tar.gz files
find backup* -mtime +1 -delete

The tar command creates a compressed archive, while the find command seeks backup files older than one day. Change the +1 parameter to +7 for weekly or +31 for monthly backups.
