NAME
znew —
convert compressed files to gzipped
files
SYNOPSIS
znew |
[-9fKtv] file ... |
DESCRIPTION
The znew utility uncompresses files
compressed by
compress(1) and recompresses them with
gzip(1).
The options are as follows:
-9- Use the -9 mode of gzip(1), achieving better compression at the cost of slower execution.
-f- Overwrite existing ‘.gz’ files. Unless this option is
specified,
znewrefuses to overwrite existing files. -K- Keep the original ‘.Z’ file if it uses less disk blocks than the gzipped one. A disk block is 1024 bytes.
-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.

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