The tarball is the most convenient file compressing/archiving tool under the Linux system. To packaged and compressed files it uses with the tar command. Here we will know how to extract tarball files coming along with .xz extension.
Step 1: Open Command Terminal
Step 2: Navigate to the folder where the xyz.tar.xz file of your resides which you want to extract.
Step 3: The XZ is a data compressor with the lossless outcome, so what we do here first we extract or tarball file form XZ and then from the TAR.
The command is:
For example: If my name example.tar.xz the command will be
Step 4: Extract file from Tar.
Now, after extracting the file from xz you will find it with now tar extension, thus finally run tar command to extract it:
tar -xf my_archive.tar
For example: If the xz extracted file name is example then the command will look like something:
tar -xf example.tar
About Tarball and its commands
The tarball is the most convenient packaging tool under Linux. It is a tar command to package and compress files.
The “x” option is used to unpack,
The “c” option is used for packaging,
The “v” option provides more process information.
The “f” option is used to indicate the package file name.
Tarball file format compressed on Linux can be opened on Windows using WinRAR.
The Linux utility tar was originally designed to make tape archives (copying files and directories to tape and then extracting or restoring files from the archive), and existing applications can use it for any device, it is one of the most commonly used commands in data backup.
c: create a backup (Create)
v: indicates echo mode (Verbose), which will generate a list of files backed up
f: Specify the backup file to be used. The parameter following it is the output backup file name.
x: Expand backup file
t: display the contents of the backup file
T: is followed by a file parameter that specifies the path to read each file to be backed up from this file. If you do not use the T parameter, you will need a parameter indicating the path to the backup file and directory.
Z: Create and unpack backup files using compression. This is the new version of GNU’s tar feature, which requires gzip to be installed at the same time.
Tar file compressing example
$ tar cvf backup.tar /etc
The above command packages all the files under /etc into the tar archive backup.tar. The first parameter of tar “cvf” is the command parameter of tar, “c” tells tar to create an archive file; the “v” option forces tar to use verbose mode, that is, print each file name during archiving; “f” option Tell tar that the next parameter backup.tar is the name of the archive file created.
The following line of commands unpacks the tar file backup.tar and places it in the current working directory. It must be stated that this is dangerous because the old file will be overwritten when the file is unpacked from the tar file.
$ tar xvf backup.tar
Before you unpack the tar file, it’s important to know where to open the file. For example, suppose the following files are archived: /etc/hosts, /etc/group, and /etc/passwd.
If you use the following command:
$ tar cvf backup.tar /etc/hosts /etc/group /etc/passwd
The directory /etc will be added before each file name. In order to expand the file to the correct location, you need the following command:
$ cd / $ tar xvf backup.tar
This is because the file extracts the path name from the archive file if you archive the file with the following command:
$ cd /etc $ tar cvf hosts group passwd
Thus the directory name does not exist in the archive file, so you need to use the “cd /etc” command to enter the directory etc before expanding the file. It can be seen that the way the tar file is created has a lot to do with where it is deployed.
$ tar tvf backup.tar
Display the index of the tar file before unpacking the tar file. In this way, you can see the directory name in the archive file related to the file name, so that the archive file is expanded in the correct location.
All Commands available for Tarball
h2s@h2s-VirtualBox:~$ tar --help
Usage: tar [OPTION...] [FILE]... GNU 'tar' saves many files together into a single tape or disk archive, and can restore individual files from the archive.
Examples: tar -cf archive.tar foo bar # Create archive.tar from files foo and bar. tar -tvf archive.tar # List all files in archive.tar verbosely. tar -xf archive.tar # Extract all files from archive.tar.
