# NAME

`znew` —
convert compressed files to gzipped files

# SYNOPSIS

`znew` | [`-ftv9K`] file ...

# 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.
