(Last checked against version &gzip-contversion;.) gunzip decompresses gzipped files. gzexe is used to create self-uncompressing executable files. gzip compresses the given files, using Lempel-Ziv (LZ77) coding. zcat uncompresses the given gzipped files to standard output. zcmp runs cmp on gzipped files. zdiff runs diff on gzipped files. zforce forces a .gz extension on all given files that are gzipped files, so that gzip will not compress them again. This can be useful when file names were truncated during a file transfer. zgrep runs grep on gzipped files. zless runs less on gzipped files. zmore runs more on gzipped files. znew recompresses files from compress format to gzip format -- .Z to .gz.
