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 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 .
