Welcome to this momentary pit stop on the road to finding what you need concerning gzip!

gzip is a single-file/stream lossless data compression utility, where the resulting compressed file generally has the suffix .gz.
gzip also refers to the associated compressed data format used by the utility.


A Brief History

Back when woolly mammoths roamed the Earth, Jean-loup Gailly and Mark Adler wrote the gzip utility to replace the Unix compress utility. At the time the continued use of compress was threatened by giant corporations holding patents on the LZW algorithm used by compress. In addition to avoiding patent infringement, gzip provided superior compression. The gzip utility and format remain in wide use, these many eons later.
