Gzip Description
GNU Gzip, a popular data compression program, was originally created by Jean-loup Gailly to support the GNU project. Mark Adler was responsible for the decompression. This program was created to replace compress due to the IBM and Unisys patents that covered the LZW algorithm used in compress. These patents made compress impossible to use, so we needed a replacement. Gzip's superior compression ratio is just an added bonus. Stable source releases can be found on the main GNU Download server (HTTPS/HTTP, FTP) as well as its mirrors. Please use a mirror if you can. Using Lempel-Ziv code (LZ77), gzip reduces file size. Each file is replaced with one with the extension ".gz" whenever possible. This allows for the same ownership, access and modification times. (The default extension for MSDOS, OS/2FAT and Atari is 'z'. If no files are provided, the standard input is compressed and output to the standard output.
