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.
