How can I extract .tar.xz or .xz files on my Linux system?. xz is a lossless compression program and file format which incorporates the LZMA/LZMA2 compression algorithms. The XZ format is a single-file compression format and does not offer archiving capabilities.
In this guide, we will see how to extract .xz files on Linux. The process will include the installation of necessary utilities and demonstrates usage with an example.
To extract .xz files on Linux – CenOS / Ubuntu, we need an xz-utils package installed on the system we’re working on. See installation below.
Install xz-utils Package on CentOS / Ubuntu / Debian
Install xz-utils package using the relevant package manager for your Linux and matched package name.
--- Ubuntu / Debian ---- $ sudo apt-get install xz-utils --- CentOS / Fedora / RHEL --- $ yum install xz
Extract .xz files on Linux
After package installation, extract your file using the command:
$ unxz file.xz
--decompress option of
$ xz --decompress file.xz
Here are supported options.
Usage: unxz [OPTION]... [FILE]... Compress or decompress FILEs in the .xz format. -z, --compress force compression -d, --decompress, --uncompress force decompression -t, --test test compressed file integrity -l, --list list information about .xz files -k, --keep keep (don't delete) input files -f, --force force overwrite of output file and (de)compress links -c, --stdout, --to-stdout write to standard output and don't delete input files -0 ... -9 compression preset; default is 6; take compressor *and* decompressor memory usage into account before using 7-9! -e, --extreme try to improve compression ratio by using more CPU time; does not affect decompressor memory requirements -T, --threads=NUM use at most NUM threads; the default is 1; set to 0 to use as many threads as there are processor cores -q, --quiet suppress warnings; specify twice to suppress errors too -v, --verbose be verbose; specify twice for even more verbose -h, --help display this short help and exit -H, --long-help display the long help (lists also the advanced options) -V, --version display the version number and exit With no FILE, or when FILE is -, read standard input.
In my case, I have a file fedora-coreos-30.20190725.0-openstack.qcow2.xz. To extract it, I’ll use:
$ unxz -v fedora-coreos-30.20190725.0-openstack.qcow2.xz fedora-coreos-30.20190725.0-openstack.qcow2.xz (1/1) 100 % 399.9 MiB / 1,555.3 MiB = 0.257 85 MiB/s 0:18
The .xz file is automatically deleted after decompression.
