NAME

objZ − Compression utility

SYNOPSIS

objZ [ options ] input

FLAGS

The objZ command accepts the following options:

−uDecompress input.  The input file must be in ALPHAMAGICZ compressed object file format. 

−vPrint the argument count, input length, and output length. 

DESCRIPTION

The objZ command takes a regular, read/write file in ALPHAMAGIC format as input and converts it to ALPHAMAGICZ compressed format. The compressed output file replaces the input file. 

When the −u flag is specified, the objZ command takes as input a file in ALPHAMAGICZ format (that is, a file previously produced by the objZ command or by the as command with the −compress flag) and converts it to ALPHAMAGIC format. 

ERRORS

When compressing an input file, the objZ command generates errors if the file is not a regular file (for example, a directory or device special file), if the file is read-only, if its header cannot be read, if the file is not in ALPHAMAGIC format, or if a compression failure occurs. 

When decompressing an input file, the objZ command generates errors if the file is not a regular file, if the file is read-only, if the file is not in ALPHAMAGICZ format, or if a decompression failure occurs.
