In a related post, you may learn about creating a gzip folder with tar in Linux. ![]() I hope this quick tutorial helped you in extracting tar xz file and you have a slightly better understanding of tar and xz files. So you need to specify which operation you are performing with tar command, compression (c) or extraction (x). Why did you need to specify x (extract ) here? Because tar can also be used for creating (compressing) files. -f means following is the archived file name.Once you have the xz compression support on your Linux distribution, you can extract the tar.xz file using the standard tar command: tar -xf On Debian or Ubuntu, you can install xz-utils with the following command: sudo apt install xz-utils You can use your Linux distribution’s package manager to install it. Most of the time, you’ll already have the xz-utils installed by default.īut you should still ensure that it is installed on your system. Xz compression tool is available through xz-utils package in most Linux distributions. You just need to make sure that you have support for xz compression utility on your Linux distribution. Extracting tar.xz file in LinuxĮxtracting a tar xz file is fairly simple. This is why the resultant tar.xz file in our scenario could be considerably smaller than 100 KB, let’s say 50 KB. XZ is one such compression tool and it utilizes LZMA compression algorithm. These compression tools will reduce the size of the resultant tar file. To further save time and bandwidth, compression utilities are used. If you use tar to combine 100 files of 1 KB each, the resultant tar file will probably be around 100 KB only. Using tar command, you can archive several files into one single file and thus you save time and bandwidth while transferring the file.īut tar itself doesn’t compress files. The main advantage of a utility like tar is in transferring files.ĭue to the overhead, transferring 100 files of 1 KB will take longer than transferring one file of 100 KB. tar.bz2 since year 2004 : No 'xvzf' or 'xvjf' required since then. at 0:42 tar xvf is the universal command for all. Tar is a utility that combines multiple files into one single file. Perhaps Super User or Unix & Linux Stack Exchange would be a better place to ask. tar.xz and you are wondering how to extract this tar.xz file in Linux command line.īefore I show you how to unzip a tar.xz file, let me quickly tell you about tar and xz. no-same-ownerĮxtract files as yourself (default for ordinary users).So you just downloaded a program or a file that ends in. You should by default get same ownership as user running untar command when not root user. You can also use cpio to extract from tar as some user:group cpio -iR user:group -F file.tar ![]() If it gets run as root you can use sudo -u username or su username -c to run command as some other user, and you should get ownership as that user then. ![]() If you are running untar as root then they get extracted with same uid:gid ownership that they were packed with by default, because root user can do chown to any user. When you extract tar files as non-root user you extract them with the user running the untar command by default, because regular user cannot do chown to other users. If you try to extract something from tar as regular user with -same-owner, in case it would try to extract files with ownership not same as user running untar command you will get "Cannot change ownership to uid x, gid x: Operation not permitted". Regular user wouldn't be able to change ownership of extracted files to root, that would be a huge security issue (you could put setuid and 777 on any file and then get root privileges that way, by changing file ownership to root). If you get root ownership on untared files you are running it as root user. If you run tar extract as non-root user it gets extracted as current user by default.
