pcat(1) MPE/iX Shell and Utilities pcat(1)
NAME
pcat — display Huffman packed files on standard output
SYNOPSIS
pcat file ...
DESCRIPTION
pcat uncompresses argument files which were compressed by pack(1) using a Huffman
minimal redundancy code. The uncompressed data is sent to the standard output. This is
handy for packed text files, but inappropriate for binary files, since the standard output is
treated as a text stream. Binary files can be decoded in place by unpack(1).
The names of compressed input files are expected to end in .z. If a specified input file name
does not end in this suffix, zcat automatically adds the .z; for example, if the command line
specifies file abc, zcat looks for abc.z.
DIAGNOSTICS
Possible exit status values are:
0 Successful completion.
n Indicates that n files could not be unpacked properly. For example, if three out of six
files could not be packed properly, the exit status is 3.
Messages
See the man page for unpack(1) for a list of error messages that pcat may produce.
PORTABILITY
x/OPEN
Portability Guide 4.0. UNIX System V. The UNIX command appends .z to the names
of packed files.
