A ZIP file is most commonly found in Windows operating systems. The Zip compression utility is common in Windows operating systems. What is a TGZ File? A TAR.GZ file is often called as and named as a TGZ file. A TAR.GZ file most commonly found in Linux/ Unix operating systems. What is a TAR.GZ File? A TAR.GZ file is a combination of a TAR file and a GZ file in that it is a TAR archive file that has been compressed with the Gzip compression utility. The Gzip compression utility is common in Linux/ Unix operating systems. What is a GZ File? A GZ file is created by the Gzip compression utility. A GZ file is a compressed single file, as the Gzip compression utility only compresses one file. If you compress multiple files with the Gzip compression utility, it produces multiple GZ files. A TAR file puts multiple files together. A TAR file does not reduce the size as there is no compression involved. What are the Differences Between TAR, GZ, TAR.GZ, TGZ, and ZIP Files? What is a TAR File? A TAR file's abbreviation stands for Tape Archive. Keep reading to learn how to use these files in Linux. This article breaks down the differences between TAR, GZ, TAR.GZ, TGZ, and ZIP files. Adding that sort of check is left as an exercise for the reader.Tar and Gzip utilities are often used together to create compressed TGZ/TAR.GZ files, which will be helpful in moving your data between systems efficiently. ![]() This won't help if a file is specified in the archive with an absolute path (which is normally a sign of malicious intent). One partial solution would be to automatically create a new directory to extract into: for f in *.tar do If both a.tar and b.tar contain the same file and try to extract it at the same time, the results are unpredictable.Ī related issue, especially when taking archives from an untrusted source, is the possibility of a tarbomb. More troubling, you may end up with a corrupted copy of the file if you try this "clever" optimization: for f in *.tar do 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. Tar: Exiting with failure status due to previous errors Meanwhile, GNU tar returns 2 and spams STDERR even with the verbose option off: tar: b.tar: Not found in archive ![]() 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. Originally, the tar command was intended for use with magnetic tape devices. ![]()
