Compress for UNIX

compress is a UNIX compression program. It introduces the LZC compression method, which is an LZW implementation which uses variable size pointers as in LZ78.

Files compressed by compress are typically given the extension .Z, and GNU tar pipes its data through compress when given the command line option -Z.

Files can be returned to their original state using uncompress.

compress has fallen out of favor because of the UNISYS and IBM patents covering the LZW algorithm used by it. For this reason gzip and nowadays bzip2 became more popular.

Compress for Mac OS X

There is also a Freeware Mac OS X application with the same name but it is completely unrelated with the former. This program supports the zip, 7z, bzip2, gzip, and tar formats.
