ZNEW(1) General Commands Manual ZNEW(1)


znewconvert compressed files to gzipped files


znew [-9fKtv] file ...


The znew utility uncompresses files compressed by compress(1) and recompresses 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 ratios.


compress(1), gzip(1)


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.
