18 Useful Tar Command with Practical Examples in Linux

The tar commands are the Linux or Unix-like operating system commands that are used to compress, gather, and archive files. In this post, we will be discussing the tar command in Linux. So, make sure to read and note them all to use them on your system.

18 Useful Tar Command with Practical Examples in Linux

The tar stands for tape archive files that create a single archive file from a large number of files for easiness of the user. You can easily know the files with their names that will be ending with “tar” and such files are called “tarballs”.

There are various commands in Linux to create tarballs such as  .tar.gz or .tgz archive files. Only a little part of the command keeps changing while the else part remains the same. Since most of the Linux beginner users are not familiar with all the commands, here we will be giving various examples for Linux tar command tape archive files.

Tar Command In Linux

The tar command in Linux is not only one command. There are various commands that can be used to compress so many files into an archive. Also, you can extract, modify, and maintain the tape archive files with the tar commands.  Therefore, knowing the tar commands is a must.

Create A Tar Archive

To create a tar archive, use the command given as follows. The tar command in Linux will be

tar -cvf file.tar /path/to/dir
# tar -cvf tecmint-14-09-12.tar /home/tecmint/

/home/tecmint/
/home/tecmint/cleanfiles.sh
/home/tecmint/openvpn-2.1.4.tar.gz
/home/tecmint/tecmint-14-09-12.tar
/home/tecmint/phpmyadmin-2.11.11.3-1.el5.rf.noarch.rpm
/home/tecmint/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

The options that we have used above are for the purpose as given below.

  • c – Creates a new tar archive.
  • v – This verbosely shows tar file progress.
  • f – The file type of the archive file.

Create a tar.gz Archive

For creating an archive with the gzip files, we have to use the “z” option. The commands tar.gz and tgz are the same and can be used to compress the gzip files into an archive file.

tar cvzf file.tar.gz /path/to/dir
tar cvzf file.tgz /path/to/dir
# tar cvzf MyImages-14-09-12.tar.gz /home/MyImages
OR
# tar cvzf MyImages-14-09-12.tgz /home/MyImages

/home/MyImages/
/home/MyImages/Sara-Khan-and-model-Priyanka-Shah.jpg

/home/MyImages/yanaguptabaresf231110.jpg

Create tar.bz2 Archive

The commands tar.bz2, tar.bz, and tb2 do the same function. To compress files that are lesser in size when compared to gzip files, we use the tar command in Linux as follows. The tar.bz2 takes more time to archive files when compared to the tar.gz archive files. Therefore, to create a highly compressed tar.bz2 archive file, we use the “j” option here.

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

/home/php/
/home/php/iframe_ew.php
/home/php/videos_all.php
/home/php/rss.php
/home/php/index.php
/home/php/vendor.php
/home/php/video_title.php
/home/php/report.php
/home/php/object.html
/home/php/video.php

Untar tar Archive

To untar means to extract an archive file. To extract a directory from the archive, we use the “x” option. If you want to extract from a different directory, you can use the “-c” option. The below tar command in Linux will untar the specified file.

## Untar files in Current Directory ##
# tar -xvf public_html-14-09-12.tar

## Untar files in specified Directory ##
# tar -xvf public_html-14-09-12.tar -C /home/public_html/videos/

/home/public_html/videos/
/home/public_html/videos/views.php
/home/public_html/videos/index.php
/home/public_html/videos/logout.php
/home/public_html/videos/all_categories.php
/home/public_html/videos/feeds.xml

Untar tar.gz Archive

The command to uncompress the tar.gz archive files is as shown in the image. Use the “-c” option to extract from a different directory.

# tar -xvf thumbnails-14-09-12.tar.gz

/home/public_html/videos/thumbnails/
/home/public_html/videos/thumbnails/katdeepika231110.jpg
/home/public_html/videos/thumbnails/katrinabarbiedoll231110.jpg

/home/public_html/videos/thumbnails/Lindsaydance101201.jpg
/home/public_html/videos/thumbnails/Mileyphoto101203.jpg

Untar tar.bz2 Archive

The highly compressed tar.bz2 files can be untarred with the following command. All the .flv files will be extracted from the archive file.

# tar -xvf videos-14-09-12.tar.bz2

/home/public_html/videos/flv/katrinabarbiedoll231110.flv
/home/public_html/videos/flv/BrookmuellerCIA101125.flv

Untar A Single File From tar Archive

To uncompress or extract a single file called cleanfiles.sh from the archive tar file cleanfiles.sh.tar, use the following command.

# tar -xvf cleanfiles.sh.tar cleanfiles.sh
OR
# tar --extract --file=cleanfiles.sh.tar cleanfiles.sh

cleanfiles.sh

Untar A Single File From tar.gz Archive

To untar a single file from the tar.gz highly compressed archive files, use the following tar command in Linux.

# tar -zxvf tecmintbackup.tar.gz tecmintbackup.xml
OR
# tar --extract --file=tecmintbackup.tar.gz tecmintbackup.xml

tecmintbackup.xml

Untar A Single File From tar.bz2 File

To extract a single from a tar.bz2 highly compressed archive file, run the following tar command in Linux.

# tar -jxvf Phpfiles-org.tar.bz2 home/php/index.php
OR
# tar --extract --file=Phpfiles-org.tar.bz2 /home/php/index.php

/home/php/index.php

Untar Multiple Files From tar, tar.gz, and tar.bz2 Archive

If you want to untar multiple files from more than one archive file, you can give the following command.

# tar -xvf tecmint-14-09-12.tar "file 1" "file 2" 

# tar -zxvf MyImages-14-09-12.tar.gz "file 1" "file 2" 

# tar -jxvf Phpfiles-org.tar.bz2 "file 1" "file 2

Untar Group Of Files Using Wildcard

For extracting a group of files from archive files, we have to use Wildcard. To extract a group of files with .php type from tar, tar.gz, or tar.bza2 archive files, use the Linux tar command as given below.

# tar -xvf Phpfiles-org.tar --wildcards '*.php'

# tar -zxvf Phpfiles-org.tar.gz --wildcards '*.php'

# tar -jxvf Phpfiles-org.tar.bz2 --wildcards '*.php'

/home/php/iframe_ew.php

/home/php/vendor.php
/home/php/video_title.php
/home/php/report.php
/home/php/video.php

Add Directories To tar Archive

To add a new directory to the existing archive file, we use the path option as r(append). For example, here we are adding php and xyz.txt directories to the already archive file.

# tar -rvf tecmint-14-09-12.tar xyz.txt

# tar -rvf tecmint-14-09-12.tar php

drwxr-xr-x root/root         0 2012-09-15 02:24:21 home/tecmint/

Add Directories To tar.gz and tar.bz2 Archive

There are no commands for adding directories to an already existing tar.gz or tar.bz2 highly compressed archive file. If you try adding a directory to either of them, you will get an error.

# tar -rvf MyImages-14-09-12.tar.gz xyz.txt

# tar -rvf Phpfiles-org.tar.bz2 xyz.txt

tar: This does not look like a tar archive
tar: Skipping to next header
xyz.txt
tar: Error exit delayed from previous errors

Verify tar, tar.gz, and tar.bz2 Archive

The option we use to verify is W(verify). To verify a tar archive file, use the tar command in Linux as given below. However, verifying tar.gz and tar.bz2 is not supported.

# tar tvfW tecmint-14-09-12.tar

tar: This does not look like a tar archive

Check The Size Of tar, tar.gz, and tar.bz2 Archive

You can check the size of tar, tar.gz, and tar.bz2 archive files with the following command. The size will be given in KB.

# tar -czf - tecmint-14-09-12.tar | wc -c
12820480

# tar -czf - MyImages-14-09-12.tar.gz | wc -c
112640

# tar -czf - Phpfiles-org.tar.bz2 | wc -c

How To Use Tar Command In Linux

To use the tar command in Linux, just follow the simple steps given here.

  • Go to the terminal program on your Linux system.
  • Now, run “tar -zcvf file. tar. gz/path/to/dir/ command to compress a directory into a file.
  • To compress a single file into an archive, use the “tar -zcvf file. tar .gz/path/to/dir/ command.
  • And to compress multiple directories into an archive, run the “tar -zcvf file. tar. gz dir1 dir2 dir3 command.

This was the simple procedure to use the tar command in the Linux system. The commands vary according to the file size and number of files. Use the tar command in Linux that we have given above using this procedure.
