Since tar overwrites files by default, the exact version of the file you end up with will depend on the order the archives are processed. The most obvious is that a particular file name may be included in more than one tar file. A warningīlindly untarring a bunch of files can cause unexpected problems. If you are a Perl programmer, for instance, take a look at the Archive::Tar module. The format is straightforward and many programming languages have libraries available to read tar files. ![]() Finally, the truly dedicated programmer could easily write an tar replacement that works exactly as desired. One approach is to use a shell for loop: $ for f in *.tar do tar xf "$f" doneĪnother method is to use xargs: $ ls *.tar | xargs -i tar xf Īlternatively, you can use one of a number of alternative tar file readers. Passing just one filename to tar xf will extract all the archived files as one would expect. It's too late rewrite tar to accept multiple archive files as input, but it's not too hard to work around the limitation.įor most people, running tar multiple times for multiple archives is the most expedient option. Meanwhile, GNU tar returns 2 and spams STDERR even with the verbose option off: tar: b.tar: Not found in archive tar: Exiting with failure status due to previous errors How do I untar a bunch of files at once? Annoyingly, the Solaris version of tar does not report any problems either in the return code or with the verbose option ( v). Unless a.tar contains a file named b.tar, the tar command has nothing to do and exits quietly. So if there are two *.tar files (say a.tar and b.tar) your command would expand to: $ tar xf a.tar b.tar So for tar extraction (the x option), the first file passed would be the archive and all other files would be the files to be extracted. The first file or directory passed was assumed to be the device that held the archive in question and any other files or directories where the contents of the archive to be included in the operation. Since it only made sense to execute tar on one device at a time, the syntax was designed to assume one and only one device. In this example we want to extract rar/rar.txt and rar/license.txt from the archive.Originally, the tar command was intended for use with magnetic tape devices. We can also extract multiple files without extracting the whole archive we will add all files and directories we want to extract one by by. $ tar -xvf rarlinux-圆4-5.4.0.tar.gz rar/rar.txt Extract Multiple Files In this example we will extract file rar/rar.txt from archive. We will specify the file or directory we want to extract after the archive name. In this example we will extract all content of the rarlinux-圆4-5.4.0.tar.gz $ tar -xvf rarlinux-圆4-5.4.0.tar.gz Extract Entire Archive Extract Single FileĪnother useful example is extracting single file from the tar.gz archive. We will use tar command with -xvf option. This will extract all file into new directory. The most used operation is extracting entire archive. In this example we will list contents of rarlinux-圆4-5.4.0.tar.gz $ tar -tvf rarlinux-圆4-5.4.0.tar.gz List Files and Directories Extract Entire Tar.gz Archive We will use tar command with -tvf option to list them. List Files and Directoriesīefore extracting or uncompressing the tar.gz file we generally need to list file and directories in the archive. gz command is used to compress, extract and list files and directories. Gz is the gzip format which is provided by all of the Linux, Unix and BSD files systems. ![]() Detailed tutorial about tar command be found in the following link. This is most used technique before compression. Tar is very old and popular format used to put separate file and directories into single file. In this tutorial we will look how to extract them easily. As a Linux system administrator we generally face with tar.gz extension files. A lot of files like source code, backup, configuration files etc. Tar and gz formats very popular in Linux, Unix and BSD world.
