Compress (software)
compress is a Unix shell compression program based on the LZW compression algorithm. Compared to gzip's fastest setting, compress is slightly slower at compression, slightly faster at decompression, and has a significantly lower Data compression ratio, compression ratio. 1.8 MiB of memory is used to compress the Hutter Prize data, slightly more than gzip's slowest setting. The uncompress utility will restore files to their original state after they have been compressed using the ''compress'' utility. If no files are specified, the standard input will be uncompressed to the standard output. Description Files compressed by ''compress'' are typically given the filename extension, extension ".Z" (modeled after the earlier pack (compression), pack program which used the filename extension, extension ".z"). Most ''tar (file format), tar'' programs will pipe (Unix), pipe their data through ''compress'' when given the command line option "-Z". (The ''tar'' program in its own does n ...

Pack (software)
Pack is a legacy Unix shell compression program based on Huffman coding. The unpack utility will restore files to their original state after they have been compressed using the ''pack'' utility. If no files are specified, the standard input will be uncompressed to the standard output. Although obsolete, support for packed files exists in modern compression tools such as gzip and 7-zip. Description of program Files compressed by ''pack'' are typically given the extension ".z" (not to be confused with the ".Z" of compress). Files can be returned to their original state using ''unpack''. In addition, there may also be a ''pcat'' command which reads in a compressed file and sends its output to stdout.
