     znew -- convert compressed files to gzipped files

     znew [-ftv9K] file ...

     The znew utility uncompresses files compressed by compress(1) and recompresses them with

     The options are as follows:

     -f      Overwrite existing '.gz' files.  Unless this option is specified, znew refuses to
	     overwrite existing files.

     -t      Test integrity of the gzipped file before deleting the original file.  If the
	     integrity check fails, the original '.Z' file is not removed.

     -v      Print a report specifying the achieved compression ratios.

     -9      Use the -9 mode of gzip(1), achieving better compression at the cost of slower exe-

     -K      Keep the original '.Z' file if it uses less disk blocks than the gzipped one.  A
	     disk block is 1024 bytes.


     The znew utility tries to maintain the file mode of the original file.  If the original file
     is not writable, it is not able to do that and znew will print a warning.
