NAME
     znew -- convert compressed files to gzipped files

SYNOPSIS
     znew [-ftv9K] file ...

DESCRIPTION
     The  znew	utility  uncompresses files compressed by compress(1) and recom-
     presses them with gzip(1).

     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 execution.

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

SEE ALSO
     gzip(1)

CAVEATS
     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.
