Gzip

GNU Operating System

GNU Gzip is a popular data compression program originally written by Jean-loup Gailly for the GNU project. Mark Adler wrote the decompression part. We developed this program as a replacement for compress because of the Unisys and IBM patents covering the LZW algorithm used by compress. These patents made it impossible for us to use compress, and we needed a replacement. The superior compression ratio of gzip is just a bonus. Stable source releases are available on the main GNU download server (HTTPS, HTTP, FTP) and its mirrors; please use a mirror if possible. gzip reduces the size of the named files using Lempel-Ziv coding (LZ77). Whenever possible, each file is replaced by one with the extension ‘.gz’, while keeping the same ownership modes, access, and modification times. (The default extension is ‘z’ for MSDOS, OS/2 FAT, and Atari.) If no files are specified, the standard input is compressed to the standard output.
