GZIP: Compression Program
util/gzip/
GZIP is a compression program from the Free Software Foundation.
GZIP uses the Lempel-Ziv algorithm (LZ77), and generally achieves
better compression than LZW (compress), Huffman coding (pack) and
adaptive Huffman coding (compact), and is patent free. Implementations
exist for VMS, MSDOS, OS/2, Atari, Unix, and Macintosh.
The standard extension for GZIP files is ".gz". GZIP is backward
compatible with compress, so it will also expand ".Z" files.
Extensions:
gz Gzipped text or data file
dgz Gzipped DVI file
pgz Gzipped PostScript file
sgz Gzipped shell archive
tgz Gzipped tar file
txz Gzipped text file
