    The tar command is used to compress multiple files and create a single archive file. It creates highly compressed file to save more disk space. The same command is also used to extract, maintain, or modify tar archives via command line .

    This tutorial will help you with the followings:

    1. How to extract .tar.gz file
    2. How to create a .tar.gz file
    3. And list .tar.gz file content without extracting

    How to extract .tar.gz file

    Use tar command with -x (extract), -z (gzip) and -f for the file name. The below example command will extract content of Backup.tar.gz file in the current directory.

    tar -xzf Backup.tar.gz 
    

    This will silently extract .tar.gz file in current directory. Use -v to enable verbose mode.

    To extract content to other directory us option -C (capital C). This will change the extract location of files.

    tar -xvzf Backup.tar.gz -C /opt  
    

    The above command will extract all files under /opt directory.

    How to create .tar.gz file

    Use -c command line option to create a tar archive. The -z option is used to compress with TAR + Gzip.

    The following command will compress all files, directories and subdirectories under the /var/log directory.

    tar -czf Backup.tar.gz /var/log  
    

    In case of absolution path, GNU tar also maintains the directory structure but skipped root (/) in file system. In the above case the archive contains structure as “var/log/” and all files under the log directory.

    You can also specify multiple files names to add them in single archive.

    tar -czf Backup.tar.gz *.log /backup/*.sql /opt/list.txt 
    

    The above command will archive all files with .log extension in current directory. All files with .sql in /backup directory and /opt/list.txt. As the absolute path is used, it will remove the / directory. You will see the message like “tar: Removing leading `/’ from member names”

    How to list .tar.gz file content

    Use -t option to list all files compressed under a .tar.gz file without extracting them. For example, execute on previously created compressed files:

    tar -tvzf Backup.tar.gz  
    
    
    -rw-r--r-- root/root    119783 2019-12-31 06:22:22 file1.txt
    -rw------- root/root    863287 2019-08-14 17:35:58 anaconda.log
    -rw------- root/root         0 2019-12-29 02:17:27 boot.log
    -rw-r--r-- root/root         0 2019-12-29 02:17:26 kdm.log
    -rw-r--r-- root/root     25643 2019-12-29 01:12:35 Xorg.0.log
    -rw-r--r-- root/root     11380 2019-11-24 17:35:39 yum.log
