pack—pack, pcat, unpack—compresses and expands files
pack [ – ] [ –f ] name … pcat name … unpack name …
pack compresses files. Wherever possible (and useful), each input file name is replaced by a packed file name.z with the same access modes, access and modified dates, and owner as those of name. Typically, text files are reduced to 60–75% of their original size. pcat does for packed files what cat(1) does for ordinary files, except that pcat cannot be used as a filter. The specified files are unpacked and written to the standard output. Thus, to view a packed file named name.z use: pcat name.z or just pcat name. unpack expands files created by pack.
