![]() ![]() Version 0.1 was first publicly released on October 31, 1992, and version 1.0 followed in February 1993. ![]() The program was created by Jean-Loup Gailly and Mark Adler as a free software replacement for the compress program used in early Unix systems, and intended for use by the Project. ![]() The term usually refers to the GNU Project’s implementation of such a tool using Lempel-Ziv coding (LZ77), for which it stands for GNU zip. Gzip is any of several software applications used for file compression and decompression. GNU Gzip is a popular data compression program originally written by Jean-loup Gailly for the GNU project. Apple has included built-in ZIP support in Mac OS X 10.3 and later, including other compression formats. Microsoft has included built-in ZIP support (under the name “compressed folders”) in versions of its Windows operating system since 1998. The ZIP format is now supported by many software utilities other than PKZIP (see List of file archivers). The format was originally created in 1989 by Phil Katz, and was first implemented in PKWARE’s PKZIP utility, as a replacement for the previous ARC compression format by Thom Henderson. The ZIP file format permits a number of compression algorithms. A ZIP file contains one or more files that have been compressed to reduce file size, or stored as-is. The ZIP file format is a data compression and archive format. I will consider zip, gzip, bzip2 and xv, i will not test compress another compression program present on Linux systems but now dated and surpassed by the other programs.īut as first thing an overview of these 4 methods/programs of compression To make amends today I will introduce the main methods to compress the file and I’ll do some tests to see how they behave. $ tar c nmap-7.60 | xz > a previous article about the tar program I mentioned gzip and bzip2 compression methods as options to create a tarball (and I forgot xz). ![]() If we can to compress normal files or directories to the tar.xz format we can use tar command with c option which will create given file or directory tar to the standard output and than we will redirect it to the xz command to compress like below. We will provide x option to tar command in order to extract tar archive. xzcat is a wrapper which will use xz command simply decompress given file content to the standard output. We will redirect xzcat command output to the tar command like below. $ tar xvf Decompress With tar Command Decompress with tar and xzcat CommandĪnother option to decompress tar.xz files is using tar and xz command separately. We will provide xvf options to the tar command but v is optional which will list extracted file names to the terminal. So we can use single tar command in order to decompress the tar.xz file. Tar command have builtin support for most of the compression format. $ file Print File Type Decompress With tar Command We will provide the file name which is in this case. We can start by checking wheter given tar.xz extension is in xz format with file command. In this tutorial we will look how to compress and decompress or extract tar.xz file in Linux. xz is very efficient compression algorithm and tool better than gzip and bzip in general. But tar is defacto standard for Linux to put given file and folders into single file. Linux provides different compression format with different tools. ![]()
