znew -- Command

Recompress .Z files to .gz files
znew [ -ftv9PK ] [ file.Z ...  ]

The command znew recompresses files from .Z (compress) format to .gz (gzip)
format.

znew recognizes the following command-line options:

-9 Use the slowest, most thorough compression method.

-f Force recompression of file even if file.gz already exists.

-K Keep a .Z file when it is smaller than the .gz file.

-P Use pipes for the conversion to reduce disk space usage.

-t Test the new files before deleting the originals.

-v Verbose mode:  display the name  and percent by  which the size  of each
   recompressed is reduced.

Notes

To recompress a file already in gzip format, rename the file to replace the
suffix .gz with the suffix .Z, and then invoke znew.

znew does  not maintain the time  stamp if you invoke  it with command-line
option -P.
