GZIP(1) GZIP(1) NAME gzip, gunzip - compression and decompression utilities SYNOPSIS gzip [ -v ] [ -level ] [ file... ] gunzip [ file... ] DESCRIPTION Gzip and gunzip perform data compression and decompression compatible with the Unix gzip file format, which uses a hybrid Lempel-Ziv 1977 and Huffman compression algorithm called `deflate'. If no arguments are given gzip compresses each file replacing it by a file of the same name with the a .gz suffix appended. If no files are given, standard input and standard output are used. Level is a single decimal digit between 1 and 9; higher numbers give better compres- sion. The default level is 6. The -v option causes gzip to report the compression ratio of each file that it com- presses. Gunzip performs the opposite operation to gzip; each file (which must have a .gz suffix) is uncompressed, and replaced by a file of the same name with the .gz suffix removed. If no files are given, standard input and standard output are used. SOURCE /appl/cmd/gzip.b /appl/cmd/gunzip.b SEE ALSO filter(2), filter-deflate(2) Page 1 Plan 9 (printed 12/30/24)
