znew - recompress .Z files to .gz files

       If the -P option is used, znew does not maintain the timestamp  if  touch(1)  does  not  support  the  -r
       option, and does not maintain permissions if chmod(1) does not support the --reference option.

                                                                                                         ZNEW(1)

       The  Znew  command  recompresses  files  from  .Z (compress) format to .gz (gzip) format.  If you want to
       recompress a file already in gzip format, rename the file to force a .Z extension then apply znew.

       znew -   recompress .Z files to .gz files

-f     Force recompression from .Z to .gz format even if a .gz file already exists.

       -t     Tests the new files before deleting originals.

       -v     Verbose. Display the name and percentage reduction for each file compressed.

       -9     Use the slowest compression method (optimal compression).

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

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