Compression programs on Linux

[ Thanks to linuxaria for this link. ]

"GNU Gzip is a popular data compression program originally written by Jean-loup Gailly for the GNU project. Mark Adler wrote the decompression part.

"gzip is any of several software applications used for file compression and decompression. 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. 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. Version 0.1 was first publicly released on October 31, 1992, and version 1.0 followed in February 1993.

"gzip is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. DEFLATE was intended as a replacement for LZW and other patent-encumbered data compression algorithms which, at the time, limited the usability of compress and other popular archivers."
