If you are a regular reader at Techglimpse, then you might have read our article on How to extract .xz file packages in Linux. Well, that tutorial was primarily aimed at installing XZ utils to read .xz file packages in Linux. But you can also use ‘tar‘ command to read and extract .xz files. To do that, you need to have a ‘tar‘ command that supports .xz file formats.
For example, assume that you have tar version 1.15.1, then surely it’s not going to help you un-compress .xz files.
Check the version of tar as below:
#tar --version tar (GNU tar) 1.15.1
Try extracting .xz file package – Assume you want to extract Python source package.
# tar xf Python-3.5.0.tar.xz tar: This does not look like a tar archive tar: Skipping to next header tar: Archive contains obsolescent base-64 headers tar: Read 1420 bytes from Python-3.5.0.tar.xz tar: Error exit delayed from previous errors
So, let us install latest version of tar command.
How to use ‘tar’ command to extract .xz file format
You can install ‘tar‘ via yum or by compiling it from source.
Update ‘tar‘ using yum
# yum update tar
In case if ‘yum update‘ shows below message, then you need to compile it from source.
# yum update tar Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * base: centos.excellmedia.net * elrepo: hkg.mirror.rackspace.com * epel: epel.mirror.net.in * extras: centos.excellmedia.net * remi: remi.mirrors.arminco.com * remi-php55: remi.mirrors.arminco.com * updates: centos.excellmedia.net Skipping security plugin, no data Setting up Update Process No Packages marked for Update
Compiling ‘tar’ from source
1. Download latest version of ‘tar‘ from here.
2. Extract the downloaded ‘tar’ package
# tar xvzf tar-latest.tar.gz
# cd tar-1.28/
# make install
Are you getting this error message during ‘make’?
"Dwarf Error: found dwarf version ‘4’, this reader only handles version 2 information"
Solution: Check this guide for the solution.
Once installed, check the version of the tar and try extracting the ‘.xz‘ files as below:
$ /usr/local/bin/tar --version tar (GNU tar) 1.28
Extract .xz file formats using tar
$tar xf Python-3.5.0.tar.xz
