How To Unzip.tar.bz2 File In Unix



The .tar portion of the file extension stands for tape archive, and is the reason that both of these file types are called tar files. Tar files date all the way back to 1979 when the tar command was created to allow system administrators to archive files onto tape. Forty years later we are still using the tar command to extract tar files on to our hard drives. Someone somewhere is probably still using tar with tape.

Note that the target directory must already exist, tar will not create it if it is not present. If you need to create a directory and have tar extract the files into it all in one command, you can do that as follows:


If we specify --strip-components=1 with our example tar file, the Ukulele Songs top-most directory within the tar file is not created on the hard drive. The files and directories that would have been extracted to that directory are extracted in the target directory.


There are only two levels of directory nesting within our example tar file. So if we use --strip-components=2, all the files are extracted in the target directory, and no other directories are created.


The tar command is used to create an archive of multiple files or directories and the bzip2 compression algorithm is used to reduce the size of the archive. The resulting archive file has a .tar.bz2 extension and can be unpacked using the tar command with the -j option.


You can use Linux tar command with option -j to extract bz2 file. As this is a also tar compressed file, You also need to use -x command line option.


An archive file are useful for creating backups, making bundle of files and save disk space. In this tutorial, you have learned how to extract a .tar.bz2 file using command line. Additionally, you learned to create .tar.bz2 file or list files without extracting it.


Source code is often packed for download as a TAR (Tape ARchive) file, that is a standard format in the Unix/Linux world. These files have a .tar extension; they can also be compressed, the extension is .tar.gz or .tar.bz2 in these cases. There are several ways to unpack these files.


Where .zip files consist of many individually compressed files, .tar files are compressed as a single package, leaving its files uncompressed. In other words, .zip files are a collection of compressed files, while .tar files are a compressed collection of files.


It depends. For sending and storing, both .zip and .tar.gz files will allow you to send relatively large packages as a single file. However, there are some pretty major differences when it comes to accessing data within the files and the compression efficiency.


This command will extract (-x) the file (-f) specified (in this case, filename.tar.gz) to the current directory. Note that this command also works with other common compression formats such as .tar.bz2.


You can create your own compressed .tar files using compression utilities such as gzip. Gzip is one of the most popular and available options, especially since it comes built in to most Linux distributions and macOS.


If you want to keep the original file after compression, there are two options. The first is the -k option, and the other uses the -c option to output the compressed file to a different file, preserving the original.


With the command prompt open, use the appropriate commands to change the current working directory (cd) to the location of the .tar.gz file you want to unzip. Alternatively, you can also specify a source and destination file path when using the tar utility.


Solution: Find a new copy of the .tar.gz file, or simply extract it as a .tar file using tar -xf filename.tar instead. If this command also throws an error, the next solution might help.


While every tar.gz file is a .tar archive, not every .gz is a .tar file. The .gz extension represents the gzip compression format, which can be applied to almost any file format to compress data and save space.


Though both .zip and .tar.gz archive and compress files, they do so in different ways. Where .zip archives and compresses individual files, .tar only archives individual files, leaving a separate compression format such as .gz (gzip) to compress all of them as a single file/archive. In other words, .zip is a collection of compressed files, while .tar.gz is a compressed collection of files.


Yes. Since .tar.gz compresses multiple files all at once, it can take advantage of similarities between individual files to save on space. Generally speaking, a collection of files archived and compressed as a .tar.gz will be more space-efficient (i.e., smaller) than the same collection compressed as a .zip.


This article will help you understand how you can handle the common file formats TAR, GZIP, BZIP and ZIP on Linux operating systems (including CentOS, Ubuntu) and even some Unix-based OSes like MacOS (OS X) via the command line either via SSH or a local terminal session.


On many Linux-like operating systems the command line tools for working with TAR, GZIP, BZIP and ZIP files are already installed, so you almost certainly don't need to install anything, but if you are running a minimal installation of your OS or if you've removed the tools in the past, follow the directions below to install what you need. Select the tab for the OS you are running:


The TAR file format is a very early archiving format that doesn't include any active compression by default. Often on Linux, items are tarred and then gzipped to compress them. TAR files typically end in .tar.


c: Create a TAR file.v: Output verbosely (you'll be told exactly what is happening in detail).f: Specify a filename for the resulting TAR file.


c: Create a TAR file.v: Output verbosely (you'll be told exactly what is happening in detail).f: Specify a filename for the resulting TAR file.z: Compress the TAR file with GZIP


Execute the following to create a single .tar.bz2 file containing all of the contents of the specified directory compressed with BZIP. (BZIP typically produces smaller files than GZIP, at the cost of more processing time.):


c: Create a TAR file.v: Output verbosely (you'll be told exactly what is happening in detail).f: Specify a filename for the resulting TAR file.j: Compress the TAR file with BZIP2


x: Extract the contents from the file specified.v: Output verbosely (you'll be told exactly what is happening in detail).f: Specify a filename to uncompress.


x: Extract the contents from the file specified.v: Output verbosely (you'll be told exactly what is happening in detail).f: Specify a filename to uncompress.z: Uncompress the tarball via GZIP.


x: Extract the contents from the file specified.v: Output verbosely (you'll be told exactly what is happening in detail).f: Specify a filename to uncompress.j: Uncompress the tarball via BZIP2.


If you'd rather specify a different directory to extract files to rather than just dumping everything in the current directory add -C /PATH/TO/DIRECTORY/ to the commands above. Replace /PATH/TO/DIRECTORY/ with the actual path to the directory where you want the files to be placed.


In most cases, once the compression is done using tar, it results in a .tar file. Further compression is done using gzip, which would result in a .tar.gz file.


The additional option z represents gzip compression. Alternatively, you can create a .tgz file which is similar to tar.gz. An example of this is shown below:


The .bz2 file provides more compression compared to gzip. However, this would take more time to compress and decompress. To create this, you need to use the -j option. An example of the operation is:


This wraps the complete details on the bz2 file and how one can easily extract it using various ways in Linux. As we have mentioned earlier, it is good to compress the file because of its reduced file size. We have described multiple procedures that can help you compress, extract, and open bz2 files in Linux without having any issues.


pigz is a parallel version of gzip. Although it only uses a single thread for decompression, it starts 3 additional threads for reading, writing, and check calculation. Your results may vary but we have seen significant improvement in decompression of some of our datasets. Once you install pigz, the tar file can be extracted with:


tbz, tbz2, and tb2 are extractly the same file format. They are short for tar.bz2. The tar.bz2 file is a bzip2 compressed tar archive file. It uses tar to archive the files first, then it uses bzip2 algorithm to compress the tar files. It decompresses similarly. First bzip2 uncompresses and then tar archive extracts it. This file is used for archiving data on Unix or Linux systems and for exchanging files on the internet.


A tar archive file contains uncompressed byte streams of the files which it contains. To achieve archive compression, a variety of compression programs are available, such as gzip, bzip2, xz, lzip, lzma, or compress, which compress the entire tar archive. Typically, the compressed form of the archive receives a filename by appending the format-specific compressor suffix to the archive file name. For example, a tar archive archive.tar, is named archive.tar.bz2, when it is compressed by bzip2.


Popular tar programs like the BSD and GNU versions of tar support the command line options Z (compress), z (gzip), and j (bzip2) to automatically compress or decompress the archive file upon creation or unpacking. GNU tar from version 1.20 onwards also supports --lzma (LZMA). 1.21 also supports lzop via --lzop, 1.22 adds support for xz via --xz or -J, and 1.23 adds support for lzip via --lzip. 350c69d7ab
