Last checked against version &gzip-contversion;. gunzip and uncompress decompress files which are compressed with gzip. gzexe allows you to compress executables in place and have them automatically uncompress and execute when they are run (at a penalty in performance). gzip reduces the size of the named files using Lempel-Ziv coding (LZ77). zcat uncompresses, and writes to standard output, either a list of files on the command line or a file being read from standard input. zcmp invokes the cmp program on compressed files. zdiff invokes the diff program on compressed files. zforce forces a .gz extension on all gzip files so that gzip will not compress them twice. This can be useful for files with names truncated after a file transfer. zgrep invokes the grep program on compressed files. zmore is a filter which allows examination of compressed or plain text files, one screen at a time on a soft-copy terminal (similar to the more program). znew re-compresses files from .Z (compress) format to .gz (gzip) format.
