NAME
       gznew -   recompress .Z files to .gz files

SYNOPSIS
       gznew [ -ftv9PK] [ name.Z ...  ]

DESCRIPTION
       gznew  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 gznew.

OPTIONS
       -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

BUGS
       gznew does not maintain the time stamp with the -P option if cpmod(1) is not available and touch(1) does not support the -r option.
