compressed files to gzipped files
utility uncompresses files compressed by
them with gzip(1)
The options are as follows:
- Use the -9 mode of
gzip(1), achieving better
compression at the cost of slower execution.
- Overwrite existing ‘.gz’ files. Unless this
option is specified, znew refuses to
overwrite existing files.
- Keep the original ‘.Z’ file if it uses less
disk blocks than the gzipped one. A disk block is 1024 bytes.
- Test integrity of the gzipped file before deleting the
original file. If the integrity check fails, the original
‘.Z’ file is not removed.
- Print a report specifying the achieved compression
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.
