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.
