PACK(1) PACK(1) NAME pack, pcat, unpack - compress and expand files SYNOPSIS pack [ - ] file ... pcat [ file ] ... unpack file ... DESCRIPTION Pack attempts to compress the files and places the results in corresponding files named file.z with the same access modes, dates, and owner as the originals. Successfully packed files are removed. Unpack reverses the process. Pcat unpacks files to the standard output by analogy with cat(1). The .z suffix may be omitted from the name of the input file for unpack or pcat. Pack encodes individual characters in a Huffman code. Option - causes statistics of the encoding to be printed. The option toggles on and off at each appearance among the list of files. DIAGNOSTICS The return value of pack, unpack, or pcat is the number of files it failed to process. No packing happens when the input can't be read or appears to be packed already, the output file name exists or is too long or can't be created, or the input has links or is a directory.
