1. To feed data through any compression algorithm.
2. tool The Unix program "compress", now largely
supplanted by gzip.
Unix compress was written in C by Joseph M. Orost, James
A. Woods et al., and was widely circulated via Usenet. It
uses the Lempel-Ziv Welch algorithm and normally produces
files with the suffix ".Z".
Compress uses variable length codes. Initially, nine-bit
codes are output until they are all used. When this occurs,
ten-bit codes are used and so on, until an
implementation-dependent maximum is reached.
