NAME
znew —
convert compressed files to
gzipped files
SYNOPSIS
DESCRIPTION
The
znew utility uncompresses files compressed by
compress(1) and recompresses
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.

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.
